Standards & References
Southwire 28kV HI-DRI Primary UD TRXLP 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
- CSA
Construction
The cable is composed of a moisture blocked reverse lay, compact stranded soft drawn copper, 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. Has a Super Smooth conductor shield. 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.
