STRESS CONE for cable terminations

摘要

The proposed utility model relates to the field of electric power and can be used in cable terminations. Stress cone comprises a cylindrical body with a through longitudinal bore, one of the end portions, which comprises a conductive polymer member formed as a cylindrical mold sleeve positioned coaxially to the longitudinal through-hole, the inner surface, which is flush with the inner surface of the through hole. The lower part of the bushing beyond the dimensions of the housing, and a large portion of the sleeve is recessed into the housing body, while its inner wall is chamfered, forming an annular space filled with material of the body made of insulating and transparent material. The wall thickness of the most part of the sleeve, the recessed inward than the wall thickness at the sleeve that extends beyond the body dimensions. Provided stress relief cone assembly, reduce the likelihood of formation of air bubbles on the surface of the insulation of high-voltage cables, increase strength, increase the probability of detection of possible faults, reduced material consumption in the manufacture and design simplification, proposed stress cone. 2 ZP f ly-1-yl.
