TWU Cable is a bare copper conductor that ranges from 14 AWG to 4/0 AWG. It features a durable Polyvinyl Chloride (PVC) insulation and jacket, providing excellent resistance to moisture, mechanical stress, and environmental conditions. Rated for 600 volts and operating temperatures from -40°C to 60°C, TWU Cable performs well in both indoor and underground conduit installations. It meets stringent CSA C22.2 No. 75 standards and complies with FT1 and VW-1 flame ratings, making it suitable for environments where fire resistance and regulatory compliance are essential.
Application
CSA certified TWU cable is good for fixed wiring in residential, commercial, and light industrial locations. Its high-purity copper conductor combined with flame-retardant PVC insulation significantly improves overall safety in tight spaces or near flammable structures. The cable is rated at 600 volts and can carry medium power loads, suitable for underground pipes, walls or wet environments. It meets CSA FT1 flame retardant rating to slow the spread of fire in the event of a fire.

Standards

- An annealed solid or stranded soft copper conductor, offering excellent electrical conductivity and long-term durability.
- The insulation is made from flame-retardant, moisture-resistant, and low-temperature PVC.
- Rated for 600 volts, this cable meets CSA C22.2 No. 75-03 and FT1 flame test standards.
- Custom colors and alternative constructions are available on request.
