This paper reports on the results of a basic inquiry for the purpose of developing extrusion-molded joints (EMJ) for use with 500-kV XLPE cable. The authors have made it clear that the factors that govern EMJ performance, like cable performance, are contaminants in the insulation and protrusions in the semiconductor layer. Through modeling experiments the authors determined the minimum breakdown strength of EMJ and used this to determine design values for 500-kV EMJ. Finally, the authors carried out breakdown tests on actual equipment, resulting in the prospect of the actual realization of 500-kV EMJ.
