Abstract

The invention proposes a strain clamp constructing method, comprising the following steps: a first pressing and connecting step wherein the inner layer wire core of a conductive wire and the second end of an anchor rod are pressed and connected; a wire releasing step wherein the conductive wire is released; a penetrating step wherein the anchor rod extends partially into a tube body from the first end of the tube body so that the first end of the anchor rod is out of the tube body while the second end is in the tube body; a second pressing and connecting step wherein the outer layer aluminum wire of the conductive wire and the tube body are pressed and connected and the tube body and the anchor rod are pressed and connected; and a connecting step wherein the first end of the anchor rod is connected with the strain string. According to the invention, the proposed strain clamp constructing method lets the outer layer aluminum wire of a conductive wire and the tube body be pressed and connected, and then, the inner layer wire core of the conductive wire and the second end of the anchor rod are pressed and connected. This means that the outer layer aluminum wire of the conductive wire and the inner layer wire core are pressed and connected, resulting in the effective holding of the conductive wire, connecting of the conductive wire with the strain string, and better transmitting force and electric charges.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a construction method of a tension clamp. Background technique [0002] At present, my country's UHV project construction has entered the stage of comprehensively accelerating construction, and the supporting power grids at all levels are developing rapidly. During the construction of power grids at all levels, the proposal of new fittings and new construction methods is of vital importance to the development of engineering construction and technology. effect. [0003] The tension clamp is used to fix the wire or lightning protection wire on the tension insulator string of the non-linear tower, which acts as an anchor, and can also be used to fix the guy wire of the guy tower. It is an important fitting in the transmission line. The holding force of the strain clamp on the wire plays an important role in the safe operation of the transmission line. ...
