Abstract

The invention relates to a dry-type cable terminal comprising an insulating sleeve, a tail pipe, a shielding sealing cover, a conducting rod and an insulating rubber layer. The insulating sleeve is provided with an inner cavity for core wires to pass through; the tail pipe at a pipe opening is arranged at the bottom of the insulating sleeve for core wires to insert in and provided with a lower perforation for the core wires to extend in the inner cavity; the shielding sealing cover at the pipe opening is arranged at the top of the insulating sleeve for the core wires to extend out; an upper perforation for the core wires to pass through the shielding sealing cover is formed on the shielding sealing cover; the conducting rod is arranged on the shielding sealing cover and electrically connected with the end part of the core wire passing from the shielding sealing cover; the insulating rubber layer is cylindrically formed on the inner wall of the insulating sleeve and fixedly connected with the inner wall of the insulating sleeve directly by the adhesiveness of the body; and a stress cone is embedded in the insulating rubber layer. The dry-type cable terminal has simple structure, maintenance free and longer service life.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a dry-type cable terminal head. Background technique [0002] With the development of my country's electric power construction, the demand for electric power continues to rise, the demand for high-voltage power cables is increasing day by day, and the products of high-voltage cable accessories are also growing synchronously. The development and update of cable terminals for inter-connection is very rapid. Since the cable terminal plays a key role in the connection between the cable and electrical equipment such as transformers and distribution boxes, its excellent structure is directly related to the safe operation of the cable. Cause large-scale power outages, and cause losses to the lives and property of the country and the people. The traditional cable terminal head is an oil-filled terminal head, which uses insulating sleeves (such as porcelain tubes or silicone rubber ...
