Description/Abstract
Most of the transmission cables installed in cable tunnels in the UK are XLPE insulated, hence they are limited to a maximum operating temperature of 90°C. Next generation polymeric dielectrics may tolerate higher temperatures, giving increased current ratings. This paper investigates the potential benefits to both the continuous and emergency ratings from using such cable circuits in tunnels which contain both 400kV and 132kV circuits. Thermal issues surrounding joints in such circuits are also considered through the use of a 2D finite element model.
