Application of YJV Power Cable Products
This product is mainly used for power transmission and distribution in rated voltage 0.6/1 kV～1.8/3 kV power transmission and distribution system. The flame retardant properties of flame retardant and halogen-free low-smoke flame retardant products are completely higher than the corresponding provisions in GB/T 18380, and can be widely used in airports, nuclear power plants, petroleum, chemical, transportation and other places where the flame retardant performance is critical.
