The invention relates to an insulated wire strain clamp fastening device. The insulated wire strain clamp fastening device comprises a wedge shell and a wedge block, wherein the wedge block is arranged in the wedge shell; the wedge shell is provided with a positioning piece; a through hole which is used for an insulated wire to penetrate in is formed in the wedge block; the wedge block is connected with a pushing assembly which is used for pushing the wedge block to move in the wedge shell; the pushing assembly is provided with a driving assembly which is used for driving the pushing assembly to move. The insulated wire strain clamp fastening device disclosed by the invention has the advantages that the wedge shell is positioned at a high-altitude position where the insulated wire needs to be installed through the positioning piece, so that the work security is ensured; the wedge block is pushed to move in the wedge shell through the pushing assembly, so that one-step clamping of a clamp core of a strain clamp is realized, and the insulated wire can be clamped; the pushing assembly is driven to work through the driving assembly, so that a thread running problem of an insulated strain clamp after installation is completely eradicated, the problem of damage caused by clamp core knocking during existing operation is solved, and the insulated wire strain clamp fastening device is safe and reliable during operation, is light in weight and convenient to take.
Description
technical field [0001] The invention relates to an insulated wire tension clamp fastener. Background technique [0002] In the power system, with the large increase of insulated lines, the running problem of insulated wire clamps occurs from time to time. Construction workers use tools and tools to knock gold tools during construction, which will cause damage to tools and metal tools, which can easily cause safety hazards. Take the span of 60 meters as an example, every time the wire is loosened by 10CM, the wire sag will drop by about 5CM, and the wire tension will drop by 25KG. The 10kV distribution network line is a three-phase three-wire line, and the 0.4kV is a three-phase four-wire line. The sag changes Not only will it affect the appearance of the line, but it will also lead to more serious consequences. The hazards are: 1) Changes in the tension of one side of the wire will cause changes in the force of the other phases of the wire, resulting in unbalanced tension on...
