Abstract

The invention provides an anti-waterlogging strain clamp which comprises a steel anchor, an aluminum pipe and a drainage plate, wherein the steel anchor is arranged at one end of the aluminum pipe and is connected with a wire arranged in the aluminum pipe. The anti-waterlogging strain clamp is characterized in that a grease injection hole is formed in the lateral wall of the aluminum pipe. Compared with the prior art, the anti-waterlogging strain clamp has the advantages that rain water is prevented from seeping into the strain clamp to cause waterlogging, frost heaving is avoided, safe and steady operation of an electric transmission line is guaranteed, the anti-waterlogging effect is good, the structure is simple, installation and operation are easy, economic performance is good, and large-scale popularization and usage can be realized easily.

Description

technical field [0001] The invention relates to a strain clamp, in particular to a strain clamp for preventing accumulation of water and used for an overhead power transmission line. Background technique [0002] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly, the operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. At present, power grid construction has become the main direction of my country's electric power construction. By 2020, a strong smart grid will be fully built, and the goal of building a world-class power grid will be initially realized. [0003] The tension clamp is used to fix the conductor or lightning conductor on the tension insulator string of the non-linear tower, and it acts as an anchor. It is also used to fix the guy wire of the guy tower. It is an important fitting in the transmission line. ...
