Current Rating of XLPE & PVC Insulated 1100 Volts grade Underground Cables

The XLPE (Cross Linked Poly Ethylene ) insulated heavy duty cables were introduced worldwide in mid sixties. These cables have overcome the limitations of PVC Insulated Cables such as thermal degradation, poor moisture resistant and thermoplastic in nature. What is current carrying capacity of a cable? The current rating of any cable is defined as the maximum current carrying capacity of the power cable under normal operating conditions of temperature,...
