Description

[0002] In China, a large number of connections of overhead transmission lines and ground wires adopt compression-type power fittings, namely strain clamps and straight-line connecting pipes, which not only bear the entire tension of the wires and ground wires but also are conductive bodies and cannot be disassembled after installation. In the processes of material, technology, production, construction and acceptance, if the wires and ground wires are not firmly and precisely attached in the compression pipes or are not penetrated in place or the steel core compression does not meet the requirements, it will be a major hidden danger for the safe operation of the line.

The X-ray detection method can directly display the compression state of the wire in the aluminum pipe, so that intuitive judgment can be easily made, and the negative film can be used as the original record for detection for long-term preservation.
