NA2XSEBY Three Core Cable,AL/XLPE/STA/PVC Cable,6/10KV 8.7/15KV 12/20KV 18/30KV

Applications

The cables are mainly used for:

· Indoors and in cable ducts

· Outdoors,underground and in water

· in power supply stations

· Transformer stations

· Industrial Plants

Due to the good laying characteristic, this cable can also be installed in difficult line guideways.

The inner conducting layer between the conductor and the XLPE insulation and the firmly bonded outer conducting layer on the XLPE insulation assures a construction free of partial discharges with high operational reliabilities.

Details

AL/XLPE/STA/PVC Cable

Medium voltage three core cable is suitable for use in power networks, in fixed installation outdoors in cable ducts or directly in the ground. Cable operational stability is enhanced because of very low dielectric loss factor, excellent insulation property of XLPE and firm bonding with conductor screen and insulation screen of semi-conductive material (extruded in one process), which makes it widely used in transformer stations, electric power plants and industrial plants.
