Background technique

The wire clamp is one of the necessary tools for power line construction. Ordinary wire clamps only have the function of clamping wires in the application of power line construction, and have no other functions. Ordinary cable clamps only indicate the model suitable for the wire and the tensile force parameters that can be tolerated on the nameplate, but no one knows whether it exceeds the tensile force range that can be tolerated during construction, which will bring safety hazards to the construction.

At present, in the technical control of maintaining "consistent conductor sag" in the construction of power lines, the operation is cumbersome, time-consuming and labor-intensive, and the original method cannot quickly and accurately meet the requirements of the "Construction Technology Acceptance Specification", resulting in uneven force between conductors. In severe cases, the pole tower, post insulator and cross arm will be skewed, twisted and deformed. To varying degrees, it affects the disaster resistance and safe operation of the line, and this problem is particularly prominent on the 10KV line.
