Overhead Line

Because the conductors used to conduct current are set up on the poles with insulators and fittings, they are called overhead lines and overhead power lines. Overhead lines are generally composed of conductors, insulators, fittings, poles and towers and their foundations, lightning protection wires and grounding devices, etc. The main function of a wire is to conduct electric current; it is the fundamental part of a circuit. When conducting electric current, insulators are needed to keep the three phases insulated from each other and from the ground. The tower is used to erect conductors so that there is a certain distance between the conductors and the ground as well as among the three phases. Fittings are metal accessories installed on poles and towers, used to connect wires, insulators, etc. The main function of a lightning rod is to protect the conductor and prevent it from being directly struck by lightning
