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.

*** AC resistance, including skin effect, and inductive reactance are calculated 
for cables in separate ducts, or spaced in air or direct burial for 1/3 CN. 
Assumed spacing is 190 mm flat axial separation. Balanced three-phase 
current loading is assumed for 1/3 CN cables.
