Product Description
This is a low smoke zero halogen (LSZH) medium voltage copper power cable, type RHZ1, with fire-retardant property, excellent insulation performance and environmental friendly halogen-free outer sheath for indoor and tunnel power transmission.
Application
RHZ1 medium voltage cables are essential for robust power distribution, supporting critical infrastructure such as utility transformer stations, power plants, and industrial complexes. They are particularly vital in the renewable energy sector, including wind and solar farms. Designed for durability in underground environments—whether in tunnels, trenches, or direct burial—these cables feature a halogen-free polyolefin sheath that ensures both moisture resistance and fire safety. For specialized requirements, RHZ1-OL and RHZ1-2OL variants offer advanced water protection, while AS (fire-retardant) versions provide enhanced security for high-risk areas.
