Generally, the power system is divided into generation, transmission, and distribution.

Electric power distribution refers to supplying power to consumers, and wiring equipment is installed on electric poles.

Wiring equipment includes complete iron, insulators, etc.

The complete iron is fixedly installed on the upper side of the electric pole in a direction perpendicular to the electric pole. It is made of insulating material at the top, and an insulator is installed to support the electric wire.

The distribution method for overhead wires or replacement of distribution lines is to have workers placed on the ground and on the poles at each pole within the line work section, and when the ground worker ties the replacement wire to the rope owned by the pole worker, the pole worker can move it. This is done by pulling up the rope and fixing it to the insulator installed on the wall.

When wiring a wire, a wire grip is used to pull the wire to obtain an appropriate dip, and the wire grip functions to grab and secure the wire.

Meanwhile, temporary hangers are used as an indirect live wire construction method to prevent electric shock accidents for workers during the live wiring work process.
