Abstract (en)
[origin: EP0645781A1] Power cable with improved dielectric strength, comprising an electrical core and a first polymeric dielectric layer for insulating the said core, characterised in that the said first dielectric layer consists of an insulating polymeric matrix containing at least one conductive polymer incorporated into the said polymeric matrix with a mass fraction such that the resulting electrical conductivity of the said first layer is less than 10<-14> S/cm for DC and less than 10<-10> S/cm for AC. <IMAGE>
