Abstract

In an insulating joint for a rubber or plastic insulated power cable, insulation shields are formed around insulation layers covering cable conductor joint portions of adjacent cables so that the insulation shields are longitudinally opposed to each other with a layer with high dielectric constant and high volume resistivity interposed therebetween. The layer comprises a mixture consisting of 100 parts by weight of a rubber or plastic as a base, 50 to 700 parts by weight of one or both of silicon carbide or zinc oxide, and 2 to 60 parts by weight of carbon black.
