Standards & References
Southwire 15kV Primary UD EPR Cable meets or exceeds the following ASTM specifications:
- B609: Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes
- B231: Aluminum 1350 Conductors, Concentric-Lay-Stranded
- B3: Soft Annealed Copper Wire
- ICEA S-94-649

Construction
The cable is composed of a moisture blocked reverse lay compressed stranded 1350-H16/26 aluminum phase conductor, covered by a semi-conducting cross-linked polyethylene strand shield, an ethylene propylene rubber primary insulation, and a semiconducting cross-linked polyethylene insulation shield. Conductors are available with 133% 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.
