DescriptionSingle conductor cable with filled strand aluminum conductors, triple extruded dry cured insulationsystem consisting of a thermosetting semiconducting conductor shield, high dielectric strengthPowerGuard-XL™ TRXLPE insulation, thermosetting semiconducting insulation shield, copper con-centric neutral wires, water blocking agents, black encapsulating cross-linked polyethylene jacket.
Design ParametersConductor: Class A or B Compressed concentric stranded aluminum alloy 1350 per ASTM B 231.Stranded conductors are water-blocked with conductor filling compound.Conductor Shield: Extruded thermosetting semiconducting shield which is free stripping from theconductor and bonded to the insulation.Insulation: Extruded, unfilled Tree-Retardant Cross-linked Polyethylene (TRXLPE) as defined inANSI/ICEA S-94-649 - 100% insulation level.Insulation Shield: Extruded thermosetting semiconducting shield with controlled adhesion to the in-sulation providing the required balance between electrical integrity and ease of stripping.Metallic Shield: Solid bare copper wires helically applied and uniformly spaced.Water Block: Water-blocking agents applied over the insulation shield and around the neutral wiresto resist longitudinal water penetration. Longitudinal water penetration shall be tested in accor-dance with the latest edition of ICEA T-34-664 except that the minimum requirement is 15 psig for 1hour.Jacket: The outer jacket is an extruded-to-fill black non-conducting cross-linked polyethylene jacket,meeting the physical requirements of Table 1 when tested by the methods specified in ANSI/ICEA S-94-649. The jacket shall be free-stripping and not interfere with an intimate contact between the neu-tral wires and the underlying extruded insulation shield. The jacket shall contain a print legendmarking, sequential length marking and three longitudinal extruded red stripes.Physical Properties of Extruded-to-Fill XLPE JacketUnaged Tensile Strength, min.

+) UL Type MV-105 PowerGuard-XL™ is rated MV-105 in accordance with the UL 1072 Standard. It should be noted that utilizing a 105°C normal operating conductor temperature will increase cable will reduce the shield fault capability slightly. If the user plans on operating these cables at 105°C conductor temperature for normal operation and 140°C for emergency overload, please contact Amerifor the applicable cable ampacity and shield fault capability ratings. Another important consideration is that the migration of soil moisture away from the cable is more likely at the higher operating coature and can result in an increase in soil thermal resistivity, resulting in an increase in conductor and soil temperature.
