Abstract

The present invention provides a large steel anchor type tension clamp for aluminum alloy cored aluminum wire conductor, the tension clamp includes a large steel anchor and an aluminum tube arranged along the same axial direction, and the aluminum alloy core aluminum molded wire is arranged on the aluminum tube Among them, the improvement is that one end of the large steel anchor is an elliptical ring, the other end is provided with a hole along its axis, and a thread is provided on the outside of the middle; the aluminum alloy core of the aluminum alloy core aluminum profile wire is arranged in the hole, An aluminum sleeve is arranged between the aluminum alloy core aluminum profile wire and the aluminum tube. Compared with the existing technology, the aluminum alloy core aluminum type wire lead wire large steel anchor type tension clamp provided by the present invention sets the aluminum alloy core of the wire inside the large steel anchor and presses it through hydraulic pressure, which greatly improves the strength of the large steel anchor. It is effective and stable to hold the wire; it adopts hydraulic crimping, the process is mature, the crimping quality is easy to be guaranteed, and the crimping problem of aluminum alloy cored aluminum wire is overcome.

Description

technical field [0001] The invention relates to a strain clamp, in particular to a large steel anchor type strain clamp for an aluminum alloy core aluminum type wire conductor used for an overhead power transmission line. Background technique [0002] The electric energy generated by the generator is boosted by the transformer, and then connected to the transmission line through the circuit breaker and other control equipment to realize the power transmission. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are erected on the ground and are composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. In the 1880s, DC transmission was first successfully realized. However, because the voltage of DC transmis...
