Home / Product / RWU90 Solar PV Cable
Engineered specifically for the North American market, the heavy-duty RWU90 solar cable is built to withstand wet environments and harsh winters. Designed with cross-linked polyethylene (XLPE), it is the ultimate choice for underground direct burial and exposed PV wiring in demanding climates.
The RWU90 (“W” stands for Wet) is intended for use in wet or dry locations, making it perfect for underground conduit systems, direct earth burial (where permitted by code), and exposed wiring for large-scale solar farms. It fully complies with the Canadian Electrical Code (CEC) for solar system wiring.
-CSA C22.2 No. 38, RoHS, Sunlight Resistant (SUN RES), Direct Burial (DIR BUR).
