XLPE got more Capacity to hold on incise of high temperature. XLPE will not deteriorate it's insulation property until it reaches 90 degree centigrade. it will not suddenly loss it's insulation property if the temperature jump above 90 degree centigrade, but the overall life of cable will be reduced. PVC can withstand temperature only up to 70 degree centigrade.
PVC is cheaper then XLPE.
PVC is thermoplastic whereas XLPE is thermosetting plastic.
PVC= poly vilyn chloride & XLPE = Cross link polyethylene.
