Standards & References

Southwire 35kV Primary UD EPR Cable meets or exceeds the following ASTM specifications:

  • B3: Soft Annealed Copper Wire
  • B8: Concentric-Lay-Stranded Copper Conductors, Hard, Medium-Hard or Soft
  • ICEA S-94-649
  • AEIC CS-8
  • RUS U-1

Construction

The cable is composed of a moisture blocked reverse lay, compressed stranded soft drawn copper, 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 either 100% insulation levels. 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. A semiconducting polyethylene jacket is also available upon request.
