3 Introduction ONE LEADER, TWO BRANDS The world’s largest cable company, the Prysmian Group, consists of Prysmian and Draka which are two of the world’s most respected commercial brands in the industry. With subsidiaries in 50 countries, almost 100 manufacturing plants, 17 Research & Development Centres and around 22,000 employees, the Prysmian Group is truly a global company. Proudly manufacturing in Australia since 1940, Prysmian understands local standards and conditions and our products are designed and developed accordingly. Prysmian specialises in integrated, added value cabling solutions highly customised to the individual specifications of customers. Prysmian operates a Quality Management System compliant with the requirements of ISO 9001:2008 and products are fully supported by the global technical and production capabilities of the Prysmian Group. Prysmian understands local standards and conditions and our products are designed and developed accordingly.

4 THIS MANUAL CONTAINS TECHNICAL INFORMATION ON A WIDE VARIETY OF COMMONLY USED MEDIUM VOLTAGE (MV) POWER CABLES MANUFACTURED TO AUSTRALIAN STANDARD AS/NZS 1429.1.  Full constructional and technical details are given for Prysmian’s standard range of MV power cables. Other constructions and variants are available by special order. For standard industrial applications, XLPE insulation is normally recommended, but for situations where the cable may be continuously subject to wet conditions, the well proven resistance of Prysmian’s EPR compound offers additional security. Both insulation systems have been assessed for long term resistance to water under the two year UNIPEDE test regime and successfully met the criteria. Prysmian’s EPR compound has also met the requirements of more onerous long term tests. The standard oversheaths supplied are either BLACK PVC (5V-90) or a combination of layers of PVC and HDPE to AS/NZS 1429.1, AS/NZS 4026 and AS/NZS 3808. For situations where limiting the emission of smoke and corrosive gases from cables affected by fire is  desirable, the use of Prysmian’s LSOH HFS-90TP sheath to AS/NZS 3808 is recommended. These cables are constructionally and dimensionally the same as AS/NZS 1429.1 cables and employ the same insulation systems but with LSOH sheaths. The tabulated data in this technical manual is valid irrespective of the sheathing option. High-density polyethylene sheath (HDPE) can be supplied where greater impermeability to moisture and greater resistance to abrasion is required for adverse installation conditions, but such sheaths are not recommended in areas of fire risk. Where protection against termites and other invasive insects is required, cables can be supplied with a covering of Nylon 12, or with two helically applied brass or stainless steel tapes. Alternatively Prysmian offer Termitex™ covering as a protection against termites. For protection against rodents, Prysmian recommend the use of armour or steel tapes. Brass or copper tapes provide only limited protection against rodents and specifiers need to be aware of the risk for each installation. Cable Components

5 Prysmian offers a choice of two standard screen sizes for different earth fault requirements for EPR and XLPE cables. For systems with small earth fault levels a light duty screen is offered for protection based on the screens having a nominal short-circuit rating of 3 kA for one second. For systems with high fault levels, a heavy-duty screen is available with a nominal short-circuit rating of 10 kA for one second. i.) Light-duty Screened Cables are for use in circuits protected by fast acting devices such as HRC fuses or systems having low I 2 t earth fault values. ii.) Heavy-duty Screened Cables are designed to carry high earth fault currents comparable with system symmetrical fault currents. They are designed for supply systems having high I 2 t earth fault values. For three core cables, one third of the required screening is nominated for each core, the fault current being assumed to be shared by all screens. The one-second earth fault current ratings are given in the data sheets for each of the medium voltage XLPE and EPR cables. These standard screens can be varied to suit individual system fault requirements. Prysmian has many alternative solutions to meet the demanding problems  faced by Utilities and Contractors in power distribution. The company provides a cable design service capable of servicing your requirements for power cable specification. Prysmian innovation has led to new products including: • New concepts for protection of cable from termites backed by sponsored CSIRO research. • Alternative solutions to armour for protection of cables from impact damage. • EPR COMPACT medium voltage cables have been developed for cost-effective replacement of networks using existing ductwork. These cables have been designed to optimise electrical and mechanical properties in dimensionally smaller cables. This has been accomplished through use of the EPRotenax™ Premium Performance insulation system, which combines maximum current carrying capacity with a rugged outer sheath and sufficient insulation thickness to deliver the same reliable service as the paper cables being replaced. Prysmian can also advise on various tree-retardant insulations and water blocking options. CABLE COMPONENTS

6 CABLE COMPONENTS DESIGNATIONS Each cable type is identified by a reference type designation for ease of reference and a full order designation which fully identifies each cable and should be used on order documentation. Cables are metre marked for ease of installation and inventory control.  All cables are listed with the voltage rating for which the cable is designed, expressed in the form Uo/U, where Uo is the nominal voltage between conductor(s) and earth and U is the nominal voltage between phase conductors. RECOMMENDED USE The cables described in this technical manual are designed to be used for the supply of electrical energy in fixed installations up to the indicated rated voltage at a nominal power frequency in the range 49Hz to 61Hz. Cables to AS/NZS 1429.1 and AS/NZS 4026 are  intended for use either installed in air, directly buried  in the ground or in ducts. Cables with LSOH sheath  have improved fire performance when installed in air and are primarily intended for such locations. Reasonable protection against mechanical damage should be provided. Cables in this technical manual are not specifically designed for use as self-supporting aerial cables, as submarine cables, where exposure to excessive heat  or corrosive products or solvent substances is involved. In case of any doubt concerning the suitability of a particular cable type for a particular use, guidance should be sought from Prysmian’s Customer  Service Centre.

132 CABLE SELECTION  Cables should be selected and used such that the product does not present an unacceptable risk or danger to life or property when used in its intended manner. Cables should also be selected so that they are suitable for the operating environment conditions e.g. use in petrochemical works, need for fire performance, the need for protection against attack by rodents, termites, etc, equipment classification and any other external influences which may exist. They should also be selected according to the appropriate rated voltage and the cross-sectional area of every conductor such that its current carrying capacity is not less than the maximum sustained current which would normally flow through it, and the short circuit current rating of conductor and screen is adequate for the prospective short circuit and time for which it persists. In addition, consideration should be given to other relevant factors, such as: •  voltage drop requirements •  operating characteristics of connected equipment •  economics ENVIRONMENTAL PROTECTION The standard cable finishes are adequate for normal environmental conditions. However, there are many installations where conditions are much more onerous than normal and some brief notes for protection of cables against hostile environments are given below. Once the type of protective covering to meet environmental conditions has been decided, it is generally possible taking voltage and current ratings into account, to arrive at the type of cable insulation to be used. OIL REFINERIES AND CHEMICAL PLANTS Polymeric and elastomeric cables are not compatible with hydrocarbon oils and organic solvents. Such oils and solvents particularly at elevated temperatures are absorbed by the insulation and sheathing materials leading to swelling and resultant damage. Semi-conductive components on high voltage cables may lose their conductive properties. It follows that where polymeric and elastomeric cables are used in locations where exposure to hydrocarbon oils and organic solvents is likely, a lead sheath is required. The most satisfactory protection for the lead sheath would be a high density polyethylene sheath with steel wire armour. For casual contact with oil spills, a Nitrile or CSP rubber sheath can be used. PVC sheaths offer good protection against chemical attack. Specifiers should contact Prysmian for recommendations regarding the protection of cables against harsh chemical environments. TERMITES, TEREDOES & RODENTS Special constructions are necessary to resist insects such as termites, as all cables with normal finishes are susceptible to their attack. If cables are installed in locations where termite attack is likely, protection may take the form of one of the following: •  Two helically applied brass tapes, the upper one  overlapping the gap in the lower one, may be incorporated into the cable design. In the case of armoured cable the brass tapes may be applied under the bedding of the armour. For unarmoured cable the brass tapes can be applied over the normal PVC or other extruded sheath followed by a PVC sheath over the brass tapes. •  A nylon jacket may be applied over the PVC or other  extruded sheath followed by a sacrificial layer of extruded PVC over the nylon to protect it from damage during installation. •  Termitex™ technology incorporated into the cable  design, for long term protection. Chemical treatment of the backfill is no longer recommended because of damage to the environment and the risk to health. The teredo worm is prevalent in tropical, subtropical and temperate oceans and estuaries. Protection is usually attained by incorporating two brass tapes under the armour of all submarine cables. In areas liable to attack by rodents, galvanised steel wire armour provides an effective barrier. A layer of nylon covering under the armour provides additional protection from insects. Prysmian have expertise in designing cables to resist boring insect and rodent attack. Please call the Customer Service Team for advice. Technical Information

133 EXPOSURE TO MECHANICAL DAMAGE  1.  Slight exposure to impact and to tensile stresses.  The application of a high density polyethylene sheath can give appreciable added mechanical protection to cables with the normal PVC sheath. This method is suitable for single and multi-core cables. 2.  Moderate exposure to impact and to tensile  stresses. Single core cables can be armoured with non-ferrous armour wire, usually hard drawn aluminium. For Multicore cables a single layer of galvanised steel wire armour is recommended. The steel wire is necessary if there is likely to be a moderate tensile stress applied to the cable during pulling in or during service. Steel wire armoured cables offer good protection against rugged installation conditions. 3.  Severe exposure to impact and tensile stresses.   The double wire armour finish offers a very high level of protection against mechanical damage whether it be impact or longitudinal tensile stress such as in subsidence areas and submarine installations on an uneven sea floor. 4. Polymeric protection against impact.   Prysmian developed AIRBAG™, which provides enhanced mechanical/impact protection keeping the handling and installation characteristics of unprotected cables. EXPOSURE TO ULTRA VIOLET RADIATION Prysmian has special materials designed to prevent UV degradation when exposed to sunlight. To be sure the correct material is used it is necessary to state at the time of enquiry and ordering that the cable will be exposed to sunlight. FIRE SITUATIONS The performance of a cable in a fire situation can be a major factor in the choice of cable type. When correctly selected, located and installed cables do not present a fire hazard but in the case of fire initiated elsewhere, cables provide a source of fuel and a possible means of propagation along its length.  Additionally cables can contribute to the emission of smoke and noxious gases injurious to equipment and human health. Evolution of smoke can reduce visibility, which can cause panic and create serious problems in evacuating personnel. The presence of acid gas in the smoke can result in corrosion, damage of electronic and other equipment and can cause intense irritation to the eyes and lungs. Cables manufactured from PVC and some other traditional materials when exposed to fire will produce dense black smoke and harmful fumes and may propagate fire when installed in bundles. Where these factors are of concern, the use of LSOH sheathed cables is recommended.  On the basis of standards in current use, cables can be divided into the following categories in relation to their behaviour in the presence of fire: Flame propagation (single cable) – when tested singly, the cable should self-extinguish within a short period of time and within a short distance from the point of application of a Bunsen burner flame. Such cables meet AS/NZS 1660.5.6 and IEC 60332 Part 1 and are often called flame retardant. Such cables will not necessarily prevent propagation along bunches of cables installed together on vertical racks and exposed to a large-scale fire source. Flame propagation (cable bunches) – when tested installed in defined bunches on a vertical ladder, the cables should not propagate flame more than a limited distance from the point of application of a ribbon burner flame front. Such cables meet AS/NZS 1660.5.1 and IEC 60332 Part 3 and are often called reduced propagation. Three categories exist in AS/NZS 1660.5.1 according to the volume of combustible material tested, Category A (7 l/m), Category B (3.5 l/m) and Category C (1.5 l/m). It should however be noted that propagation of fire is often a function of installation conditions and appropriate care should be taken to ensure that the test category chosen is representative of the actual installed condition. Low smoke zero halogen cables – have controlled limits on smoke evolution when cable samples are burnt in a closed 3m cube smoke chamber and controlled limits on acidic and corrosive gases when subject to material pyrolysis in a tube furnace. Such cables meet AS/NZS 1660.5.2 (IEC 61034) for smoke emission and AS/NZS 1660.5.4 (IEC 754-2) for determination of degree of acidity by measurement of pH and conductivity and are often called LSOH. By nature of their typical intended use the MV power cables of this type may be used where the performance of the cable in case of fire is important, either for limitation of the propagation of flame along cable bunches or the limitation of smoke and corrosive gas emissions. Reduced flame propagation variants of all cables in this technical manual can be supplied LSOH sheaths for situations where limiting the emission of smoke and corrosive gas from the cables if affected by fire is desirable. TECHNICAL INFORMATION 

134 It is important to know whether the system to which the cable is connected is classified as earthed or unearthed. Supply authority systems are generally, though not always, earthed design. Mining systems are usually the unearthed design. Prysmian products are suitable for voltages that are commonly used in Australia. Voltage is usually expressed in the form Uo/U and Um.   Uo is the rms power frequency voltage between phase and earth.  U is the rms power frequency voltage between phases.  Um is the maximum continuous rms power frequency voltage between any two phases for which the cable is designed. It excludes momentary variations due to fault conditions or sudden disconnection of large loads. CABLE VOLTAGES  CABLE SELECTION VOLTAGE RATING The selection of standard cables for particular supply systems depends on the system voltage and earthing arrangements. Category A – system in which any phase conductor that comes in contact with earth or an earth conductor is disconnected from the system within 1 minute. Category B – system which, under fault conditions, is operated for a short time with one phase earthed, not exceeding 8 hours on any occasion and total duration of earth faults in any year not exceeding 125 hours. Category C – system which does not fall into Categories A and B. Note: If an earth fault is not automatically and promptly isolated, the extra stresses on the cable insulation during the fault reduce the life of the cable to a certain degree. If the system is expected to be operated fairly often with a permanent earth fault, it may be advisable to classify the system in Category C.

135 CURRENT RATINGS  The current ratings indicated in this manual have been based on the calculation procedures as recommended in IEC 60287 and the following assumptions. Rating factors should be applied to cover any variation. •  Max. continuous conductor temp. = 90°C •  Ambient air temperature = 40°C •  Ambient ground temperature = 25°C •  Depth of laying = 0.8m •  Thermal resistivity of soil = 1.2°C.m/W •  Balanced load, comprising either a single three core  cable or three single core cables, in trefoil formation touching throughout, with the screens bonded at both ends of the route. •  Installation conditions: 1.  Direct Buried:  Cables are installed direct in the ground, with suitable compacted backfill 2.  Buried Singleway Ducts:  Cables are installed with one cable per duct 3.  In Free Air:  Cables installed shielded from direct sunlight and with a minimum clearance from any vertical wall of 0.3xCable Dia. and 0.5xCable Dia. for single and three core cables respectively to ensure free air circulation. In order to select the appropriate cable for a given application, consideration must be given to the nature of the installation. It is not possible to provide a definitive guide to specifying the correct cable type for every situation, this choice must be made by the specifier and/or installer based upon a knowledge of the installation, applicable regulations and the characteristics of available cable designs. General guidance on the use of cable types included has been given above, but for further information and guidance it is recommended to make reference to the appropriate cable standard (e.g. AS/NZS 1429.1 or AS/NZS 4026). TEMPERATURE LIMITS In respect of thermal effects the temperature limit given for each cable type is the maximum temperature due to any combination of the heating effect of current in the conductors and ambient conditions. All insulation and sheathing materials become stiffer as their temperature is lowered and due regard has been taken of this factor in the guidance on minimum installation temperature. The materials used for these cables are compatible with temperatures of 90ºC for continuous operation and 250ºC for short circuit conditions of up to 5 seconds. The fault ratings for the conductors and the metallic screens are provided for a time period of 1 second. When other times (t) between 0.2 and 5 seconds are required, the appropriate rating may be obtained by multiplying the 1 second rating by the factor: 1/√t. The ratings for the screens are based upon the traditional adiabatic method, which provides a substantial safety margin when account is taken of the heat loss occurring in practice. The non-adiabatic method to IEC standards can be used according to  AS/NZS 1429.1 when agreed between the purchaser and supplier. This can provide substantial systems savings. Short circuit capacity that is related to the energy expended during a short circuit. It is equated to the mass x specified heat capacity x temperature change in the conductor. Two types of conditions have to be considered – symmetrical and earth short circuit currents. Various cable designs have different nominated maximum temperatures after short circuit, depending usually on the type of insulation and sheathing, and these temperatures should not be exceeded.  Economics important criteria related to cable economics are the initial system cost and annual cost of losses. Economics are generally considered on a present value calculation based on initial cost and discounted cost of losses. Data provided in the tables assists specifiers to estimate purchase and running costs. TECHNICAL INFORMATION 

136 It is recommended that all cables described in this manual be installed in accordance with the Electricity supply authority Specifications or Regulations, the Wiring Rules and any other appropriate national regulations or legislation. In installing cables, care should be taken to ensure that the ambient and cable temperature has been above 0ºC for the previous 24 hours to avoid the risk of cracking of the oversheath. For groups of parallel single core circuits, the cables should be installed in trefoil touching formation as hereunder: i) Two conductors per phase. ii) Three conductors per phase. It is good practice when planning ducts or trenches to prescribe a bending radius of 3 metres for 11kV, 22kV and 33kV cables and 2 metres for cables below 11kV.  The following tables set out the recommended minimum bending radii for single or multicore polymeric insulated cables greater than 1.1/1.1kV: – Recommended duct sizes are given in the following table: – Where: D = Overall diameter of cable in mm. D = Diameter over Nylon jacket component in mm. The radius is related to the inner surface of the cable and not the axis. The recommendation for installation allows for the cable to be pulled under tension. Where cables are placed in position adjacent to joints and terminations and the bending is carefully controlled, the controlled bending radius as given in the data tables may be used. Sidewall Bearing Pressures need to be considered also. Using a pulling eye on the conductor: Copper       – 0.07 kN/mm 2  of conductor  Aluminium, Stranded   – 0.05 kN/mm 2  of conductor Using a pulling eye on the Steel Wire Armour: P = 0.005 D 2 Using a Stocking grip: P = 0.0035 D 2   Where:   P = Tension in kN   D = Cable diameter in mm Notes:1.  When considering the use of a stocking grip the  tension should not exceed the values given for a pulling eye on the conductor(s). 2.  Refer also to Maximum Sidewall Bearing Pressure. Using bond pulling: By this method the cable is tied at intervals to a steel hawser which is coiled onto a take-up winch in the normal manner. The hawser would be twice the length of the cable being pulled. In this way the pulling load on the cable is kept to a low value and risk of damage to the cable is minimised.

137 TECHNICAL INFORMATION  MAXIMUM SIDEWALL BEARING PRESSURE Another factor which can limit the maximum tension that a cable can withstand is the sidewall bearing pressure exerted on a cable in duct bends and elbows. The sidewall bearing pressure formula is expressed as: SWBP = [W 2  + (T/(0.0098 x R)) 2 ]     (equation 1)   as most of the time, [T/(0.0098 x R)] 2   W 2    equation 1 can therefore be simplified as follows: SWBP ≈ T/(0.0098 x R)       (equation 2)  From eqn. 2 = T = 0.0098 x R x SWBP   (equation 3)  From eqn. 2 = R = T / (0.0098 x SWBP)   (equation 4) Where:   SWBP = sidewall bearing pressure (kg/m)   W = weight of cable per unit length (kg/m)    T = cable pulling tension (kN)    R = radius of the bend or elbow (m) The recommended maximum SWBP for sheathed cables shall be 1450kg/m. Examples: 1. To find out the maximum pulling tension of a  12.7/22kV 240mm 2  copper single core PVC sheathed  cable based on its minimum recommended bending radius: First calculate the minimum recommended bending radius without considering SWBP: = 18 x Cable Diameter = 18 x 40.5mm = 729mm Then calculate the maximum pulling tensions:a) Maximum pulling tension for straight pull:  T = 0.07 kN/mm 2  x 240 mm 2     = 16.8 kN b) Maximum pulling tension when taking maximum  SWBP into consideration. From Equation 3: T   = 0.0098 x 0.729 x 1450   = 10.4 kN We have to select the lesser of the two pulling tensions, i.e. 10.4kN. In this example, the maximum SWBP dictates the maximum pulling tension. 2. To find out the minimum bending radius for the same cable if we do need a pulling tension of 16.8kN: From Equation 4: R  = 16.8 / (0.0098 x 1450)   = 1.2m JOINTS AND TERMINATIONS Whilst jointing and terminating of Medium Voltage Polymeric Cables is routine, care is needed to maintain clean working conditions and in ensuring that the insulation semiconducting screen is completely removed and properly connected at the stress control areas. Reference should be made to literature for suitable systems available from Prysmian. TESTS AFTER INSTALLATION High Voltage d.c. testing of primary insulation is not recommended and can be detrimental to the cable and accessories. AS/NZS 1429.1 describes an a.c. voltage test at power frequency that should be applied for 24 hours at the normal operating voltage of the system. A sheath integrity test (e.g. with a 1000 Volt minimum rated insulation resistance tester) may be applied between the outer-most metallic layer and the earth to identify post-installation damage, provided the metallic layer is isolated from earth at the joints, terminations, etc. SHORT CIRCUIT FORCES When single core cables are installed touching, special attention should be given to cleating and strapping arrangements to contain the repulsive forces under short circuit conditions. Longitudinal thrust and tensions in cable conductors may be considerable and may cause buckling of conductors and other damage in a joint or termination. When cables are installed, provision should be made to accommodate the resulting longitudinal forces on terminations and joints. Sharp bends and fixings at a bend should be avoided. PREVENTION OF MOISTURE INGRESS Care should be exercised during installation to avoid any damage to cable coverings. This is important in wet or other aggressive environments. The protective cap should not be removed from the ends of the cable until immediately prior to termination or jointing. When the caps have been removed the unprotected ends of the cable should not be exposed to moisture. The possibility of damage to moisture seals during handling and installation or during storage of the cable should be considered and where such damage may have occurred, the seals should be inspected and remade if necessary.
