Background
The distribution wire is a distribution line erected in the air by a pole standing on the ground for transmitting electric energy. The distribution line is the last loop for transmitting the electric energy to the user, and whether the distribution line is safe and reliable directly influences whether the user can use the electric energy or not. The insulator is used for supporting a wire and ensuring that the wire is sufficiently insulated from electrical equipment such as a cross arm, an electric pole and the like. At present, the fixing mode of the distribution line and the insulator is binding, namely binding the distribution line on the insulator by using a binding wire. This approach has the following drawbacks:

2. Binding-wire is often worn and broken: the binding wire not only needs to bear the load of the vertical direction of the lead and the pulling force of the horizontal direction in the process of running on the line, but also is often corroded by sunlight, rain and chemical substances. This causes the binding wires to break frequently, which results in grounding of the wires and reduction in power supply reliability.
Therefore, in order to improve the power supply reliability of the distribution line and the safety of construction work, a reliable wire clamp is needed to fix the distribution line on the insulator.
