Regarding the allowable long-term working temperature of wire and cable cores, rubber insulation is usually 65℃, PVC insulation is 70℃ and cross-linked polyethylene insulation is 90℃. The maximum allowable temperature of the conductor during a short circuit (the longest duration does not exceed 5s): is 160°C for PVC insulation and 250°C for cross-linked polyethylene insulation. ZMS cable production company to introduce the difference between XLPE cable and PVC cable.
Cross-linked polyethylene(XLPE) insulated power cables are a common category of cables used in civil engineering, including normal, flame retardant, fire-resistant, and halogen-free low smoke flame retardant. Cross-linked polyethylene insulated power cables are resistant to environmental stress. It also has the characteristics of high mechanical strength, chemical resistance, excellent electrical performance, simple structure, lightweight, and easy to use.
