Power cables are an essential element in the transportation and distribution of electricity in all modern economies. Medium-voltage (MV) and high-voltage (HV) AC power cables are the workhorses transporting bulk power across the electrical grid. Historically, there have been two types of MV power cable: Paper Insulated Lead Covered (PILC) and Polyethylene cables. The cable design can typically be a single-core cable or a three-core cable. If we go back more than 50 years to the 1960s, paper insulation was the dominant technology used in copper and aluminum distribution power cables.
