A permanently elastic dielectric composition comprising a resilient dielectric base material, an electrically polarizable component having low electrical conductivity to increase the relative dielectric constant of the composition, and a component displaying metal conductivity for maintenance of the relative dielectric constant at high power frequencies.

Elastomeric composition for providing electrical stress control

A multi-core cable connection for medium voltage cables in which each core connection includes a pair of prefabricated permanently elastic stress control elements, each of which has a sleeve-like main body of insulating material and a conductive sleeve-like insert in the body, extending out of one end thereof and bridging the core insulation and the conductor connector.

Multi-core cable connection for medium voltage cable

A dielectric composition for influencing electric fields comprising a dielectric base material having electrically conductive and electrically insulating platelet-shaped particles and stress control devices made therefrom.
