12/20KV N2XSY cable

6/10KV 12/20KV 18/30KV Copper Core XLPE Insulated PVC Sheath N2XSY Cable

Cable Construction

Circular bare copper-conductor of stranded wires to HD 383

Inner semi-conducting coating

Conductor insulation of cross-linked Polyethylene (XLPE), PE-compound DIX8 to HD 620.1

Outer extrusion of semi-conducting coating spliced with the insulation

Wrapping of conductive material

Shield: Braiding of copper wires with one or two tape(s) applied helically


PVC outer jacket, compound DMV6 to HD 620.1

Jacket color: Red


Suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switch boards and power stations. Due to the good laying characteristic, this cable can also be installed in difficult in difficult line guide ways.

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.
