Connection fittings are mainly used to assemble suspension insulators into strings, and

The string insulators are connected and suspended on the cross arm of the pole tower. Suspension clamp and strain clamp and insulation

The connection of the substring, the connection of the cable fittings and the pole towers also use the connection fittings.

Connecting fittings, also known as wire-hanging parts. This kind of fittings is used for connecting insulators into strings and connecting fittings and fittings. It bears mechanical loads.

Connect the fittings. This kind of hardware is specially used for connecting various bare wires and lightning protection wires. The connection bears the same electrical load as the wire, and most of the connection fittings bear all the tension of the wire or lightning protection wire.

Protective fittings. This kind of hardware is used to protect wires, insulators, etc., such as the equalizing ring for protecting insulators, the heavy hammer used to prevent the insulator string from being pulled up, and the anti-vibration hammer and guard wire to prevent wire vibration.

Contact the fittings. This kind of hardware is used to connect hard and soft busbars to the outlet terminals of electrical equipment, T-connections of wires, and non-stress-bearing parallel connections. These connections are electrical contacts. Therefore, higher electrical conductivity and contact stability of the contact fittings are required.

Fixed fittings, also known as power plant fittings or high-current bus fittings. This kind of fittings is used for fixing and connecting various hard or soft bus bars and post insulators in power distribution devices. Most of the fixed fittings are not used as conductors, but only serve as fixing, supporting and suspending. However, since these fittings are used for large currents, all components should have no hysteresis loss.
