Used for underground DC power supply feeder to cathodic protection systems for pipelines, storage tanks, and other buried or submerged structures.
Nexans Cathodic Protection Cables are suitable for the conditions of use, as required by the Canadian Electrical Code, Rule 80-004(1). These constructions have an excellent record of field use in the Alberta petroleum industry, and are accepted by the Alberta Municipal Affairs (Electrical Safety Information Bulletin, Sept. 1999).
Conductors larger than 8 AWG are compact round stranded copper. 8 AWG conductors are compressed stranded copper, in accordance with applicable CSA and ASTM standards.
Black insulation is high molecular weight, medium density polyethylene, in accordance with ASTM Specification D1248, Type II, Class C, Category 4, Grade J4 and E9.
Coloured insulation is high molecular weight, medium density polyethylene, in accordance with ASTM Specification D1248, Type II, Class D, Category 4, Grade J4 and E9.
For both black and colours, this insulation material offers mechanical toughness superior to that of low density polyethylene, with no compromise of dielectric strength.
Insulation colour is black for positive (anode) cables. Colours are as specified for negative (cathode) cables.
Maximum conductor termperature rating is 75°C.
