Tension insulator string hanging device

Abstract

The invention discloses a tension insulator string hanging device, which comprises a connecting beam, an insulator string, a connecting plate and a crimping pipe which are arranged on a cross arm, wherein one end of the insulator string is connected with the connecting beam, the other end of the insulator string is connected with the connecting plate, one end of the crimping pipe is fixed on the connecting plate, one end of a cable is connected in the crimping pipe, the crimping pipe comprises a pipe body and a contraction sleeve, the contraction sleeve is arranged at one end, away from the connecting plate, of the pipe body, the crimping pipe is sleeved with a slip ring capable of axially sliding along the crimping pipe, the cable is sleeved with a cable clamp, the cable clamp is connected with the sliding ring through a connecting bolt, when the cable is disengaged from the crimping pipe, the sliding ring slides in the axial direction of the crimping pipe under pulling of the cable clamp and enables the contraction sleeve and the cable to be held tightly, and a cushion layer is arranged on the contact surface of the cable clamp and the cable. According to the invention, when thecable slides off from the crimping pipe under the action of external force, the contraction sleeve arranged on the crimping pipe can tightly hold the cable in time so as to avoid the breakage of the cable and avoid the great economic loss.

Description

technical field [0001] The invention relates to the technical field of electric power fittings, in particular to a tension insulator string hanging device. Background technique [0002] High-voltage cables are usually hung on the high-voltage iron tower through an insulator string hanging device. The existing insulator string hanging device mainly includes at least one insulator string and a connecting plate. One end of the insulator string is fixed on the cross arm of the high-voltage iron tower, and the other end is It is connected with the connecting plate, and the connecting plate is fixedly provided with crimping tubes for connecting cables. The crimping tube is a tubular structure. When connecting, the end of the cable is inserted into the crimping tube, and then the crimping tube is squeezed and deformed by special crimping equipment, so that the crimping tube is firmly set on the cable. In actual use, when the cable is subjected to external forces such as strong win...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the cable is easy to slip off from the crimping tube under the action of external force during the use of the existing insulator string hanging device, causing major economic losses, and to provide a tension insulator string hanging device device, which can effectively solve the above problems
