12/20kV Cu(AL)/XLPE /copper tape screen/SWA(STA)/PVC Power Cable(3 CORE) AND 12/20 Cu(AL)/XLPE/copper wire+copper tape screen/AWA(ATA)(1 CORE )/PVC Power Cable.
Single core/Three-cores power cables can be arrranged according to Chinese GB standard, Internation IEC standard, Ameica ASTM standard, British BS standard, etc.
XLPE Cable with Copper Wire Screen
Integrated intelligent high voltage XLPE cable can online monitor the operation parameters during the operation of high voltage cable. It can online real-time monitor cable actual operation temperature and then realize online temperature measurement and control, online fault location and improve the operation load of cable system. Besides, it also can accomplish online monitoring of partial discharge, current carrying capacity and outer sheath condition. It can provide important specification judging evidence for cable safety operation and more load operation, ensure the cable safety operation, extend cable service life, develop the cable transmission capability to the deepest extent, reduce the operation cost, meet the requirement of customers’ safety and economy, and then decrease the replace frequency, reach energy saving and consumption reducing, increase utilization of transmission energy, achieve the best effect of transmission performance of XLPE cable, and have great economic benefit and social benefit.
Medium voltage cables for distribution networks; also for connection to generation units and plant and process connection. To be laid directly in ground, outdoors, indoors and in cable ducts.
