Abstract
The invention relates to an elastomeric end piece intended for high voltage electric cables. By incorporating into the elastomer one or more substances whose electrical impedance reduces as a function of the voltage applied, such as silicium carbide, zinc oxide doped with cobalt or bismuth, the titanates or zirconates of alkaline or alkaline-earth metals, the distortion of the radial electric field at the end of the cable which could cause disruptive breakdown is avoided. Application to the end of high voltage electric cables, especially in polluted urban areas.
