Application
PowerGuard®-XL cables are intended for use in wet or dry locations for distribution of single or three phase medium-voltage power. They are suitable for installation in duct or direct burial. 

Construction
Single conductor cable with filled strand aluminum conductors, triple extruded dry cured insulation system consisting of a thermosetting semiconducting conductor shield, high dielectric strength PowerGuard®-XL TRXLPE insulation, thermosetting semiconducting insulation shield, copper concentric neutral wires, water blocking agents, black encapsulating cross-linked polyethylene jacket.

Description
Conductor: Class A or B Compressed concentric stranded aluminum alloy 1350 per ASTM B 231, or compact strand per AST B400. Stranded conductors are water-blocked with conductor filling compound.
Conductor Shield: Extruded thermosetting semiconducting shield which is free stripping from the conductor and bonded to the insulation.
Insulation:  Extruded, Tree Retardant Cross-linked Polyethylene (TRXLPE) as defined in ANSI/ICEA S-94-649 - 100% insulation level.
Insulation Shield:  Extruded thermosetting semiconducting shield with controlled adhesion to the insulation providing both electrical integrity and ease of stripping.
Metallic Shield: Solid flat strap copper wires helically applied and uniformly spaced.
Crushing of round wires to make flat wires shall not be allowed. Water-blocking agents applied over the insulation shield and around the neutral wires to resist longitudinal water penetration. Longitudinal water penetration tested in accordance with the latest edition of ICEA T-34-664 except that the minimum requirement is 15 psig for 1 hour.
Water Block: Water-blocking agents applied over the insulation shield and around the neutral wires to resist longitudinal water penetration. Longitudinal water penetration shall be tested in accordance with the latest edition of ICEA T-34-664 except that the minimum requirements are 15 psig for 1 hour.
Jacket: Black insulating sunlight resistant linear low-density polyethylene encapsulating the neutral wires with three extruded red stripes and NESC lightning bolt symbol.
