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.
