1. Adopt the structure of connecting hardware and pin insulator as a whole. The connecting hardware can be used as forced torque span parallel groove clamp or compression type connecting pipe, among which bolts are used for special pin insulator connection and fixation.

2. The upper end of the insulator hardware is equipped with its own bolt structure, which is simpler in structure and more convenient in installation.

3. The connecting hardware adopts three section torque type span parallel groove clamp, the middle section is directly fixed by the bolt on the upper end of insulator, and there is a gland on both sides, which increases the connecting area and conductivity, and reduces the resistance; because of the span design, it can meet the different specifications of conductor, reduce the product type and inventory, and facilitate the purchase and maintenance of users.

4. The three section torque type span parallel groove clamp adopts the high elastic aluminum alloy gland and adopts the torque design, so that the gland keeps good contact with the conductor, reduces the maintenance workload and improves the power reliability.

5. It is designed with a complete set of silicone rubber cover, which is safer and more beautiful.
