A connection apparatus of a cross arm of a light weight buffer metal for a high-tension wire is provided to obtain reliability of power supply by preventing the generation of power outage in advance. A connection apparatus of a cross arm of a light weight buffer metal for a high-tension wire includes a supporting cover frame(10), a supporting rubber(20), a cross arm supporting part(30) and a cross arm(40). In the supporting cover frame, an electric pole connection hole inserted with the top of an electric pole(50) is formed, and a supporting protrusion is formed on a bottom center of a top supporting plate. The supporting rubber has a protrusion groove(21) into which the supporting protrusion of the top supporting plate is inserted, and adheres to the electric pole. In the cross arm supporting part inserted between the top supporting plate and a bottom supporting plate of the supporting cover frame, a protrusion groove which the supporting protrusion of the top supporting plate is inserted into, is formed on the center. The cross arm is fixed by a connection bolt through an installation guide hole(41), and a connection part(44) of an insulator(43) is connected with a nut(45) and penetrates the installation guide hole. |
