Equipment for power cable junction and power cable equipped therewith.

摘要

The present invention relates to a power-cable joint accessory intended to be mounted on a stripped terminal part of this cable and to provide the dielectric strength around this stripped terminal part, the cable comprising a conducting core and, in succession around the core, an inner semiconducting screen, a dielectric layer, an outer semiconducting screen and an external protective jacket (sheath); the accessory comprises a first part intended to reconstitute the dielectric layer, and a second part and a third part which together are intended to reconstitute the inner and outer semiconducting screens respectively, characterised in that the first and second parts of the joint accessory are produced identically and simultaneously, made of an insulating polymeric matrix containing at least one conductive polymer which is incorporated, into the polymeric matrix, with a mass fraction such that the resulting electrical conductivity of the first and second parts is less than 10<-14> S/cm for DC use and less than 10<-10> S/cm for AC use, and in that the third part has an electrical conductivity less than 1 S/cm. <IMAGE>
