ABSTRACT:
A means for relieving dielectric stress at a termination of a shielded and insulated high voltage cable. A smooth geometry high permittivity homogeneous material tube coaxially contacts both the ground electrode and the high voltage electrode. The tube consists of an elastomeric material having a permittivity in a range of from 10 to 25. The elastomeric material is non-rigid, thereby enabling the tube to be more readily fitted firmly around the cable and into the housing of the stress relief means. The ground electrode is the outer portion of the housing and diverges from the opening of the housing at the vicinity thereof in a direction toward the high voltage electrode. This dielectric stress relief means provides a satisfactory electric field gradient in applications wherein the rating is in a range from 15 kilovolts to 35 kilovolts.
