Description

Nexans ENERGEX® CN Distribution Cables are single conductor concentric neutral power cables available in voltage classes from 15 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.  For single phase systems the conductance of the neutral is equivalent to that of the phase conductor. 

These cables are LEAD FREE and RoHS compliant. 

 


Application

ENERGEX® CN Distribution Cables are suitable for use above ground in open air, in conduit in air, directly buried, in underground duct, or aerially when suspended on a messenger wire.   While suitable for use in cable tray in a typical Utility installation, ENERGEX® CN is not TC rated and cannot be used in cable tray in an installation subject to the requirements of the Canadian Electrical Code.  ENERGEX®  CN cables are suitable for continuous operation at 90ºC wet or dry, and are sunlight resistant.
