Product Description

Applications
For use on single phase and three phase primary underground distribution systems operating at 20kV phase to phase. Suitable for either direct burial or installation in ducts.

Construction
Copper concentrically stranded compressed conductor, triple single head extruded conductor shield, XLPE (cross-linked polyethylene) insulation and easy strippable insulation shield, all dry nitrogen cured; solid bare copper wires uniformly spaced around the cable as a concentric neutral; LLDPE or PVC jacket.
