Furthermore, a locking nut is connected to the tightening bolt through threads, and the locking nut is connected with the insulator. The locking nut is locked to the insulator, so that the puller bolt is locked, and the puller bolt is prevented from being loosened due to vibration of the insulator.
Furthermore, a second T-shaped groove is formed in the lower end of the section of the first wire clamp and the section of the second wire clamp after fixed connection, and the second T-shaped groove is connected with the upper end of the busbar in a clamped mode. Because the busbar is longer, the busbar is clamped in a mode of combining the first wire clamp and the second wire clamp, so that the first wire clamp and the second wire clamp are installed more quickly.
Further, the support horizontal pole passes through the chemical anchor bolt to be fixed at the tunnel top, be equipped with between support horizontal pole and the tunnel top and cup joint and be in oblique gasket on the chemical anchor bolt. Because the tunnel top is the arc, so increased the area of contact who supports horizontal pole and tunnel top with the gasket to one side, make support that horizontal pole and tunnel top laminating are inseparabler.
Further, the insulator external material is silicon rubber. The insulator made of silicon rubber as an external material has good hydrophobicity, ageing resistance, tracking resistance and electric corrosion resistance, high tensile strength and bending strength, high mechanical strength, good impact resistance, shock resistance and brittle failure resistance, light weight and convenient installation and maintenance.
Furthermore, the first wire clamp and the second wire clamp are fixedly connected through a fastener and fixed at the lower end of the insulator through a screw, and the screw is made of stainless steel. Use the screw to fix first fastener and second fastener at the insulator lower extreme, simple structure, convenient operation, the screw adopts stainless steel material moreover, can prevent the rust corrosion busbar that produces after the screw corrosion.
