Problems solved by technology

[0002] The matching part between the frame of the sub-conductor spacer and the main body of the clamp for transmission lines is generally a circular structure. This kind of matching structure is prone to wear and tear on the matching part between the frame of the spacer and the main body of the clamp in the case of breeze vibration or strong wind, resulting in damage to the spacer or even Losing the protective function will affect the safety of the transmission line. In addition, the sub-conductor spacers used in the transmission line generally adopt a groove structure frame, which has low strength and is prone to wear and tear.

Abstract

Provided is a sub-conductive wire spacing bar which comprises a polygon framework and a wire clamp body which is connected with the framework. The head end part of the wire clamp body presents to be a hooked shape. The internal arc surface of the hook is provided with an elastic anti-skid protective mat. The cross section of the framework presents to be H-shaped. The framework and the wire clamp body are provided with through holes with different hole diameters. The through holes with different hole diameters are internally provided with cone-shaped clamping pieces which are connected with the framework and the wire clamp body. A gap is arranged between axial directions of the framework and the wire clamp body of the spacing bar so that wearing caused by mutual friction between the framework and the wire clamp body is avoided.

Description

technical field [0001] The invention relates to a sub-wire spacer, in particular to a wear-resistant sub-wire spacer. Background technique [0002] The matching part between the sub-wire spacer frame and the main body of the clamp for transmission lines is generally a circular structure. This kind of matching structure is prone to wear and tear on the matching part between the spacer frame and the clamp body in the case of breeze vibration or strong wind, resulting in damage to the spacer or even Losing the protection function will affect the safety of the transmission line. In addition, the sub-conductor spacers used in the transmission line generally adopt a groove structure frame, which has low strength and is prone to wear and tear. Contents of the invention [0003] The object of the present invention is to provide a wear-resistant sub-wire spacer, which has high strength and is not prone to wear. [0004] The specific solution of the present invention is: a seed wir...
