Abstract:
1. A structure for installing a lightning arrester between a cross arm mounted to an upper end of an electric pole and a power line, wherein an end of a dead end clamp connected with the power line is connected to one end of the lightning arrester by a first pin, an intermediate portion of the dead end clamp and a voltage inlet portion of the lightning arrester are connected to each other via a connection wire, an insulation reinforcing insulator is integrally coupled to a voltage outlet portion formed on the other end of the lightning arrester, and an end of the insulation reinforcing insulator is connected to one end of a shackle by a second pin, the shackle is connected to the cross arm, a disconnector is connected to the voltage outlet portion of the lightning arrester, a grounding line for diverting an abnormal voltage to the ground is connected to the disconnector, and an insulation cover for insulating the power line and the dead end clamp from the outside surrounds the dead end clamp and the voltage inlet portion of the lightning arrester.
