Power fittings are metal accessories that connect and combine various devices in the power system and play a role in transmitting mechanical load, electrical load and some protection.

Classification of power fittings:

1. According to the function and structure, it can be divided into suspension clamp, tension clamp, connection fittings, connection fittings, protection fittings, equipment clamps, T-shaped clamps, bus fittings, stay wire fittings, etc; According to the purpose, it can be used for line fittings and substation fittings.
2. According to the product units of electric power fittings, they are divided into four units: malleable cast iron, forging, aluminum copper aluminum and cast iron.
3. It can also be divided into national standard and non-national standard
4. According to the main performance and use of fittings, fittings can be roughly divided into the following categories
1) . suspension fittings, also known as support fittings or suspension clamps. This kind of hardware is mainly used to hang the conductor insulator string (mostly used for linear pole tower) and the jumper on the insulator string.
2) Anchorage fittings, also known as fastening fittings or wire clamp. This kind of fittings is mainly used to fasten the terminal of the conductor to fix it on the resistant insulator string. It is also used for fixing the terminal of the lightning conductor and anchoring the stay wire. Anchorage fittings bear all the tension of conductor and lightning conductor, and some anchorage fittings become conductors
3) . connecting fittings, also known as wire hanging parts. The fittings are used for connecting insulator strings and connecting fittings with fittings. It bears mechanical loads.
4) . connecting fittings. This kind of fittings is specially used to connect various bare conductors and lightning wires. The connection bears the same electrical load as the conductor, and most of the connection fittings bear all the tension of the conductor or lightning conductor.
5) . protective fittings. Such fittings are used to protect conductors and insulators, such as grading ring for protecting insulators, heavy hammer for preventing insulator string from pulling up, anti vibration hammer and protective rod for preventing conductor vibration, etc
6) . contact fittings. The fittings are used for connecting the hard bus and soft bus with the outgoing terminal of electrical equipment, T-connection of conductor and non stress parallel connection, etc. these connections are electrical contacts. Therefore, high conductivity of contact fittings is required
