CSA RWU90 cable conductors are made of bare ACM aluminum, compacted or compressed into a Class B stranded structure, which is not only lightweight, but also has excellent conductivity, effectively reducing the overall system cost. The cable insulation layer uses heat-resistant and moisture-proof low-temperature cross-linked polyethylene (XLPE) material with excellent thermal stability and mechanical strength. It can operate reliably in environments as low as -40°C, and is particularly suitable for outdoor wiring, underground laying or pipeline laying in cold areas. CSA RWU90 complies with the Canadian Electrical Code CSA C22.2 No.38 standard, ensuring its reliability in safety, durability, and performance.
Application
CSA RWU90 1000V cable is widely used in various power transmission environments that require high reliability and weather resistance. It is particularly suitable for underground wiring, building incoming lines, power distribution networks, and permanent wiring installations in industrial sites. Because it uses cross-linked polyethylene (XLPE) insulation, it has excellent heat and moisture resistance, so it can still work stably in cold, humid, or mechanically stressed environments. The cable is commonly used for underground power supply mains in residential developments, power access systems in commercial complexes, and transmission cable laying in factories and infrastructure projects.

Certification
RWU90 cable has passed UL certification, and the certification number is UL-CA-2545592-0, which can be verified on the UL official website. This certification not only verifies the compliance of the cable in terms of structure, insulation materials and electrical performance, but also further proves its suitability for reliable operation at a rated voltage of 1000V. UL certification is an important quality guarantee for wires and cables to enter the Canadian and international markets, and it has met strict industrial standards in terms of fire resistance, heat resistance, and mechanical strength.
