Download PDF Download Excel Table

Construction:

Conductor:Class B compressed stranded bare copper per ASTM B3 and ASTM B8
Insulation:Cross Linked Polyethylene (XLPE)

Applications and Features:

Southwire’s RWU90 is designed for direct earth burial (with protection as required by the inspecting authority). For service entrance above or below ground. The minimum recommended installation temperature is minus 40°C (with suitable handling procedures). Maximum conductor temperature is 90°C. Note: Standard black is sunlight resistant and marked "SR". Standard coloured insulation is not sunlight resistant.

Specifications:

ASTM B3 Soft or Annealed Copper Wire

ASTM B8 Concentric-Lay-Stranded Copper Conductors

CSA C22.2 No. 38 Thermoset-insulated wires and cables

CSA SUN RES - for Sunlight Resistant rating

CSA AWM I A/B FT1
