    How to solve the damage of the overhead line and how to protect the overhead line from lightning. Due to its structure and installation conditions, it is prone to water and non-volatile. When the insulation layer is ruptured or unsealed, water enters the aluminum wire through the suction effect of the capillary tube and agglomerates at the lower part of the arc. Because the polluted water of the environment is acidic, it produces an oxidation reaction with aluminum to produce white powder. This kind of oxygen
