Cu/XLPE/CAS/HDPE 36/66kv 48/66kv XLPE Insulated Underground Power Cable48/66kv Copper Conductor XLPE Insulation Creasing-Aluminum Sheathed and PVC Sheathed Logitudinal-Block-Water Power CableConductorsThe cable conductors can be made of copper or aluminium. The choice is a matter ofcustomer's preference or current carrying capacity. Large size solid conductors aremade of aluminium.Available conductor constructions:(1)round solid conductors up to 2000 mm2 (RE)(2)circular stranded compacted conductors up to 1200 mm2 (RM)(3)circular conductors with shaped wires up to 2000 mm2 (RM, Keystone conductors)(4)segmental conductors up to 2500 mm2 (RMS, Milliken conductors)(5)oval shaped stranded compacted conductors up to 800 mm2 for external gaspressure cables (OM)The conductors are manufactured to meet the requirements of the relevant national andinternational standards. For special applications the conductors can be made watertight.InsulationThe insulations for low pressure oil filled cables and for conventional pipe type cablesare lapped from high quality insulating papers. Subsequently the paper insulated cable cores are impregnated in appropriate vessels with low viscous oil or high viscouscompound.For manufacture of XLPE insulated high voltage cables, GW cables disposes of four extrusion lines. Highest quality standards together with latest process control equipmentand combined with decades of experience ensure manufacture of cables meeting the highest requirements and enabling development of most advanced power cable systems.Metallic CoveringConventional paper insulated cables require a pressure proof and watertight metallicenclosure, acting also as metallic screen. At GW cables both, extruded lead sheath aswell as the aluminium sheath can be applied. These types of metal sheaths are, of course,also used on XLPE insulated cables. While the lead sheath leads to smaller dimensions, the aluminium sheath provides high short circuit current carrying capability and lower weight.As the XLPE insulated cables do not require an internal overpressure, they are usuallyequipped with a copper wire screen. For radial moisture barrier a coated aluminium foil is longitudinally applied. The combination with the polyethylene oversheath is called aluminium polyethylene laminated (APL) sheath. This solution provides high short circuit capability and watertightness combined with lowest weight and smallest dimensions.A combination of the copper wire screen with a metal sheath is also possible. For all XLPE insulated high voltage cables, the space between cable core and water barrier is made longitudinally watertight.OversheathAn extruded polyethylene sheath is provided as the standard solution. With respectto its excellent mechanical strength it is the optimum for buried cables. If required,a conductive layer can be provided on the outside. For special applications differentsheathing material may be used, optimized for the purpose.Cabling and ArmouringFor the conventional pipe type cables as well as for the City Cable, laying-up of thethree cores and provision of the strong steel armour is an essential feature. Therefore,GW cables disposes also of the appropriate machinery to carry out these productionSteps.  Size of Structure and Referent Weight             Voltage        Nominal Cross Nominal Conductor DiameterThickness of Inner SheathThickness   of   SheathThickness   of Outer Sheath Thickness   of Water Resistant Layer       Thickness   of Al   SheathThickness   of   Sheath      Thickness   of Appr.
