What Are The Categories Of Electricity Funds?

What are the categories of power fittings:

1. According to the function and structure, it can be divided into Power Connectors, tension wire clamp, connection fittings, connection fittings, protection fittings, equipment wire clamps, T-type wire clamps, busbar fittings, wire pulling fittings and other categories; according to the purpose, it can be used as line fittings and substation fittings.

2. According to the power fittings product unit, it can be divided into forgeable cast iron, forging, aluminum copper aluminum and cast iron, a total of four units.

3. It can also be divided into national standards and non-national standards

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 wire clamps. This kind of fittings is mainly used to suspend the wire insulator string (mostly used for straight pole towers) and suspend jumpers on insulator strings.

2), anchoring fittings, also known as fastening fittings or wire-resistant wire clamps. This kind of hardware is mainly used to fasten the terminal of the conductor to fix it on the line-bearing insulator string. It is also used to fix the terminal of the lightning conductor and anchor the wire. The anchoring hardware bears all the tension of the conductor and lightning conductor. Some anchoring hardware becomes a conductor.

3) Connecting hardware, also known as hanging wire parts. This hardware is used to connect insulators into strings and connect hardware with hardware. It bears mechanical load.

4) Connecting hardware. This 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 all the tension of the wire or lightning conductor.

5) Protective hardware. This 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 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 fittings are required to have higher conductivity and contact stability.

7) Fixed fittings, also known as power plant fittings or high-current busbar fittings. This type of fittings is used to fix and connect various hard busbars or soft busbars to support insulators in distribution equipment. Most of the fixed fittings are not used as conductors, but only for fixing, supporting and suspending. However, since these fittings are used for high currents, all components should be free of hysteresis loss.
