Description

Nexans ENERGEX CN Distribution Cables are single conductor concentric neutral power cables available in voltage classes from 5 kV to 46 kV.  These cables are manufactured using the latest in clean compound handling technology.  ENERGEX CN has a semiconducting crosslinked polyolefin (XLPO) conductor shield, a tree retardant crosslinked polyethylene (TRXLPE) insulation and a strippable semiconducting crosslinked polyolefin (XLPO) insulation shield.  Three phase systems typically use CN cables with 1/3 neutrals. 

These cables are LEAD FREE and RoHS compliant. 

 


Application

ENERGEX CN Distribution Cables are suitable for use above ground in open air, in cable tray, in conduit in air, aerially when suspended on a messenger wire, and either directly buried or in duct. ENERGEX CN cables are suitable for continuous operation at 90ºC wet or dry, and are sunlight resistant.
