MATCHING AND CONTACT SECURING LOCK FOR A PREFABRICATED CABLE HEAD IN PARTICULAR THAT FOR SINGLE-CORE HV POWER CABLES

摘要

1. The prefabricated cable head, especially for single-core high voltage power cables, with internal surface of the cylindrical axial central port in the body is shaped along its entire length in the cylindrical and conical shape in such a way that the bases of truncated cones in the middle of the port are facing the central part of the body, which in its upper part is shaped as an elongated cone with thread cut on its external surface, especially a single thread, having an external cone at the entrance and in the middle part of the body changing into a flat protective protrusion, which on the underside has a deep pocket with a rim-like shape on the circumference changing at its bottom into a shallow toroid preferably with circular cross-section, with an upper internal flange fitted inside inseparably and permanently, passing in permanent contact with the external surface of the lower part of the body into a lower setting bell, inside which close to its bottom there is a flexible press-on contact sealing in the form of an oblique ring facing the bottom of the head, a clamp being fitted on the external circumference of the cylindrical part of the core of the smallest diameter, and the internal surface of the lower setting bell is lined with a layer of heat resistant conductive fabric, the entire surface of the port ....IMAGE
