Improved stay insulator

Abstract

The invention relates to an improved stay insulator. The insulator comprises an insulator body, a connecting column, a fixing frame, two clamping units, a tensioning unit and a locking unit, the connecting column is installed at the lower end of the insulator body, the locking unit is connected between the connecting column and the fixing frame, the two clamping units are installed at the left endand the right end of the fixing frame, and the tensioning unit is installed in the fixing frame. According to the invention, the problem that a traditional insulator only has a hanging and locking effect on a cable passing through the insulator can be solved; in the prior art, the tension of the cable needs to be manually adjusted by a worker, the high-altitude operation of the worker is often influenced by wind power, and the action amplitude is large when the cable is tensioned, so that the risk of high-altitude operation of the worker is increased, and the like.

Description

Technical field [0001] The invention relates to the technical field of insulators, in particular to an improved pull-wire insulator. Background technique [0002] Insulators are devices installed between conductors of different potentials or between conductors and ground potential components, and can withstand voltage and mechanical stress. It is a special insulation control that can play an important role in overhead power transmission lines. In the early years, insulators were mostly used for telegraph poles, and slowly developed at the end of high-voltage wire connecting towers with many disc-shaped insulators. In order to increase the creepage distance, they are usually made of glass or ceramics, called insulators. The traditional insulators only have the effect of hooking and locking the passing cables, and they do not have the function of controlling the tension of the cable. The tightness needs to be manually adjusted by the staff. The staff working at heights are often a...

Problems solved by technology

It is a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed in high-voltage wires. There are many disc-shaped insulators hanging on one end of the connection tower. It is In order to increase the creepage distance, usually made of glass or ceramics, they are called insulators. Traditional insulators only have the effect of anchoring and locking the passing cables, and do not have the function of controlling the tension of the cables. The tension of the cables The tightness needs to be manually adjusted by the staff. The staff working at heights is often affected by the wind, and the movement range will be larger when the cables are tightened, which increases the risk of personnel working at heights.
