It adopts imported environmentally friendly cross-linked polyolefin, which has excellent flexibility, is not easy to burst, and has flame retardant properties that cannot be burned. It has low smoke to almost no smoke and no poisonous gas. WDZ-BYJ adopts IEC227 standard environmental protection new-generation flame retardant cross-linked low-smoke halogen-free polyolefin as insulation replacement product. It has excellent flame retardant, low smoke, and low toxicity properties, and overcomes the traditional halogen-containing When the polymer is burned, it produces the most fumes, which make people uncomfortable and corrode the equipment, which represents the development trend of today's wire and cable.The characteristics of WDZ-BYJ wires are that they have low halogen-free, low-halogen, low-smoke, and low-smoke halogen-free characteristics. If a fire occurs, the spread speed is slow, the concentration of toxic smoke is low, the visibility is high, and the amount of harmful gas released to people is small. Disaster site personnel evacuated. Low-smoke halogen-free cables are extremely corrosive when burning, thus avoiding damage to instruments and equipment. The characteristics of low-smoke, low-halogen, and halogen-free cables make the cable materials resistant to aging and UV rays, among others. When the irradiation performance is large, the performance is greatly improved, thereby extending the service life of various cables.
