Abstract
A cold shrinkable termination for an electric power cable that includes an insulation tube and stress control glue. When the cold shrinkable termination is mounted on the electric power cable, the stress control glue fills a gap between the electric power cable and the insulation tube so as to prevent local electric field concentration from occurring at an exposed end of the electric power cable. The stress control glue has a dielectric constant within a range of 5 to 100. In this cold shrinkable termination, a stress control glue with high dielectric constant is provided to optimize the electric-field distribution on an insulation surface of the electric power cable. Thereby, the structure of the cold shrinkable termination is simplified and the cost thereof is reduced. The cold shrinkable termination may be adapted to an electric power cable used to transmit voltage less than 26/35 kV.
