    Product Details

    Complete Cable: Cross-linked semi-conducting conductor shield, insulation and semi-conducting insulation shield are extruded over stranded copper conductor and cured in a single operation. Uncoated copper flat strap neutrals (helically applied) and extruded-to-fill black jacket are applied over the cable core. PowrPak® cables meet the latest ANSI/ICEA S-94-649 and AEIC CS8 specifications for Ethylene Propylene Rubber (EPR) insulated concentric neutral cable except for dimensional requirements.

    Conductor: STRANDFILL®, bare, compact, concentric lay stranded copper tested in accordance with ICEA T-31-610.

    Conductor Shield: Extruded semi-conducting thermosetting polymeric stress control layer.

    Insulation: Extruded Ethylene Propylene Rubber (EPR) Class II and III.

    Insulation Shield: Extruded semi-conducting thermosetting layer, clean and free stripping from insulation.

    Copper Flat Straps: Bare annealed copper flat strap neutrals designed to meet customer fault current requirements.

    Jacket: Black, non-conducting Linear Low-Density Polyethylene (LLDPE) extruded to fill spaces between flat straps.

    Features and Benefits:
    • Reduced overall diameter for tight duct applications without reducing insulation wall
    • No environmental concerns
    • Higher emergency ampacity capabilities
    • Less costly than PILC
    • Millions of feet successfully installed and operated since its introduction in 1989
    • Triple-extruded for clean interfaces
    • Class 10,000 environment utilized for cable core material handling
    • Flexibility for easy handling
    • Excellent moisture resistance
    • Improved temperature rating over PILC
    • Low dielectric loss
    • Deformation-resistant
    • High dielectric strength
    • Excellent resistance to water treeing
    • Clean-stripping insulation shield without the use of a release agent

    Temperature Rating:
    • Normal . . . . . . . . . . . . . . . . . . . . . . . . .105°C
    • Emergency* . . . . . . . . . . . . . . . . . . . . . .140°C
    • Short Circuit . . . . . . . . . . . . . . . . . . . . .250°C
    * Operation at the emergency overload temperature shall not exceed 1500 hours cumulative during the lifetime of the cable.

    Applications: PowrPak® cables are intended for use in dry or wet locations for today's aging and expanding urban underground distribution systems of utilities where PILC has been used previously. It is specifically designed to be used in urban underground network systems where existing duct space is limited.

    Options:
    • Class C copper conductors
    • Reduced insulation wall thickness
    • BIFILL® blocked conductor and cable core/ jacket. Tested in accordance with ICEA T-34-664
    • Dry nitrogen cure
    • True Triple Extrusion
    • Red stripes on jacket
    • Deformation-resistant polypropylene jacket
    • 3 X 1/C triplex or parallel
