Standards & References

Southwire 35kV HI-DRI Primary UD TRXLP Cable meets or exceeds the following ASTM specifications:

B231: Aluminum 1350 Conductors, Concentric-Lay-Stranded
B609: Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes
B3: Soft Annealed Copper Wire
ICEA S-94-649
AEIC CS-8
RUS U-1

Construction

The cable is composed of a moisture blocked unilay compressed stranded 1350-H16/26 aluminum phase conductor, covered by a semi-conducting cross-linked polyethylene strand shield, a tree-retardant cross-linked polyethylene primary insulation, and a semi-conducting cross-linked polyethylene insulation shield. Conductors are available with 100% insulation level. A concentric neutral of bare copper wires and a sunlight resistant, -40°C rated, insulating linear low density polyethylene jacket are applied over the insulation shield. The cable is identified by surface print on the jacket and with the lightning bolt symbol for supply cables indented in the jacket. Red extruded stripes available upon request.
