Performance And Use Of Electrical Fittings
Insulation Piercing Connector is a metal accessory that connects and combines various devices in the power system, and plays a role in transmitting mechanical loads, electrical loads and certain protective functions.
According to the functional structure, power fittings can be divided into categories such as suspension clamps, tension limiters, connection fittings, protective fittings, equipment clamps, T-type clamps, busbar fittings, and wire pulling fittings. According to their uses, they can be divided into line fittings and substation fittings.
According to the power fitting product unit, it can be divided into forgeable cast iron, forging, aluminum copper and cast iron.
If the main performance and use of the fittings are roughly divided into the following categories.
1) Suspension fittings, also known as support fittings or suspension clamps. This kind of fittings is mainly used to suspend the conductor insulator string (mostly used for straight pole towers) and suspend jumpers on insulator strings.
2) Anchor fittings, also known as fastening fittings or wire clamps.
3) Connection fittings, also known as hanging parts. This kind of hardware is used to connect insulators into strings and to connect hardware with hardware. It bears mechanical loads.
4) Connecting hardware. This kind of hardware is specially used to connect various bare wires and lightning conductors. The connection bears the same electrical load as the wire, and most of the connecting hardware bears the full tension of the wire or lightning conductor.
5) Protective hardware. This kind of hardware is used to protect wires, insulators, etc., such as equalizing rings for protecting insulators, heavy hammers for preventing insulator strings from being pulled up, and anti-vibration hammers and protective wires for preventing wire vibration.
6) Contact hardware. This kind of hardware is used to connect hard busbars, soft busbars and outlet terminals of electrical equipment, T-connections of wires and non-load-bearing parallel connections, etc. These connections are electrical contacts. Therefore, the contact hardware is required to have higher conductivity and contact stability.
7) Fixed hardware, also known as power plant hardware or high-current busbar hardware. This kind of hardware is used to fix and connect various hard busbars or soft busbars and support insulators in the power distribution device. Most of the fixing hardware is not used as a conductor, but only for fixing, supporting and suspending. However, since these hardware are used for large currents, all components should be free of hysteresis loss.
