Introduction To The Specific Functions Of Different Types Of Electrical Fittings

1) Suspension fittings: This hardware fittings for transmission lines is mainly used to hang wires or optical cables on insulators or towers (mostly used for straight poles)
2) Tension fittings: It is used to fasten the wire terminal to fix it on the tension insulator string, and can also be used on the ground wire, optical cable and pull wire (mostly used on corners or terminal towers)
3) Connection fittings: Also known as hanging wire parts; mainly used to connect insulators into strings and connect fittings to fittings. It bears mechanical loads.
4) Connection fittings: Specially used for the connection of various exposed wires and ground wires. The connection fittings bear the same electrical load and mechanical strength as the wires.
5) Protective fittings: This kind of fittings are used to protect wires, insulators, etc. Such as equalizing rings, shock-absorbing hammers, protective wires, etc.
6) Contact fittings: It is used to connect hard busbars, soft busbars and outlet terminals of electrical equipment, T-connections of wires and parallel connections that do not bear force, etc.
7) Fixing hardware: used to fasten the conductor terminal to the tension insulator string. It can also be used for ground wires, optical cables and cable pulls (mostly used at corners or terminal towers).
