Abstract

The temperature distribution along the length of the termination of a single core cable as well as the maximum temperature location are calculated using an analytical method. Also, parameters affecting the maximum temperature along the length of the medium voltage cable termination such as the ambient temperature, the cable load current, insulation thermal conductivity, and termination dimensions (outer jacket length, length of the semi-conductor, length of the field regulator, thickness of the insulation, and thickness of the jacket) are discussed. The analytical method used is based on the heat flow produced by the cable conductor and heat transfer by conduction, convection, and radiation.
