This product is suitable for subway or light rail DC traction power cables with a rated voltage of 1500V (maximum working voltage of 1800V).
The structure of this product has the following characteristics:
1. Copper core conductor is used, with low resistivity, good conductivity, and excellent mechanical and physical properties;
2. It adopts cross-linked polyethylene insulation, which has excellent electrical and mechanical physical properties;
3. Adopting a comprehensive waterproof layer structure, including wrapped waterproof tape, longitudinally wrapped aluminum/plastic composite tape (if necessary), and extruded polyethylene inner protective layer, it has excellent waterproof performance;
4. Adopt wrapped high flame retardant tape, copper tape or steel tape armor (if necessary), with good flame retardant and rodent proof functions;
5. The outer sheath of the cable is made of weather resistant low smoke halogen-free flame-retardant polyolefin material, which has the properties of UV protection, flame retardancy, non toxicity, and low smoke.
This product has high environmental safety and reliability, long service life, and does not require frequent maintenance after cable installation.
