ApplicationsPowerGuard® cables are intended for use in wet or dry locations for distribution of single or three phase medium-voltage power. These cables may be installed in ducts or direct buried.
ConstructionCross-linked semi-conducting conductor shield, insulation and semi-conducting insulation shield are extruded over an aluminum conductor and cured in a single operation. Uncoated copper tape (helically applied) and overlaying black PVC jacket are applied over the cable core. The conductor Class B compressed concentric lay filled stranded 1350 aluminum. Conductor shield is an extruded semi-conducting thermosetting polymeric stress control layer. Insulation is extruded, TRXLPE (Tree-Retardant Cross-linked Polyethylene). Insulation shield is an extruded semi-conducting thermosetting layer, clean and free-stripping from insulation. The metallic shield is flat uncoated 5-mil-thick copper tape helically applied with minimum 25% overlap. The jacket is sunlight and moisture resistant black, non-conducting PVC (Polyvinyl Chloride)

Notes
- Extruded layer thicknesses and insulation and insulation shield diameters are in accordance with ANSI/ICEA S-97-682 for shielded power cables rated 5-46 kV and also meet the requirements of the latest revisions of AEIC CS8.
- Ampacity based on earth thermal resistivity of 90ºC-cm/watt, 105ºC conductor temp., 20ºC earth ambient temperature, 75% load factor and 36" depth of burial. Values are based on one three-phase circuit, one conductor per phase, in flat adjacent configuration (direct buried) with metallic shield bonded at each end.
Dimensions and weights not designated minimum or maximum are nominal values and subject to manufacturing tolerances. In this context, weight means mass.
