ConstructionConductor: Class A or B compact 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 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 the required balance between electrical integrity and ease of stripping.Metallic Shield: Solid bare copper wires helically applied and uniformly spaced.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 requirement is 15 psig for 1 hour.Outer jacket: An extruded-to-fill black non-conducting cross-linked polyethylene jacket, meeting the physical requirements the tables below, when tested by the methods specified in ANSI/ICEA S-94-649. The jacket shall be free-stripping and not interfere with contact between the neutral wires and the underlying extruded insulation shield. The jacket is sunlight resistant. The jacket shall contain a print legend marking, sequential length marking and three longitudinal extruded red stripes. Designed for 40 years of service.
