N2XSY Single Core Cable,CU/XLPE/CTS/PVC Cable,6/10KV 8.7/15KV 12/20KV 18/30KV

Applications

N2XSY is a single core cable with a stranded copper conductor, XLPE insulation, and PVC oversheath. 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.

Overview

CU/XLPE/CTS/PVC Cable

The N2XSY (medium cable）has a single core copper stranded class 2 conductor with cross-linked polyethylene(XLPE)insulation, copper tape screen, and polyvinyl chloride(PVC) oversheath. N2XSY cable is widely used for power distribution networks, transformer stations, switching blocks and power plants, including in the renewable energy sector, the N2XSY offers a low factor of dielectric loss and excellent insulation property of XLPE for high operational reliability. It should not be subjected to heavy mechanical or tensile strain. It can be manipulated and installed in ambient temperatures ranging between -5℃ and +70℃.
