Is the fittings in overhead line what content to point to?

1. According to the function and structure, it can be divided into hanging wire clip, tensioning wire clip, UT wire clip, connecting metal clip, connecting metal clip, protection metal clip, equipment wire clip, T type wire clip, busbar metal clip, pull wire clip and other categories; It can be used as wiring fittings and transformer fittings according to the purpose.
2. According to the product unit of electric power fittings, it can be divided into malleable cast iron, forging and pressing, aluminum, copper, aluminum and cast iron, altogether four units.
3, can also be divided into gb and NON GB
4. According to the main properties and uses of gold fittings, they can be roughly divided into the following categories
1) Suspension fittings, also known as support fittings or suspension clamp. This kind of fittings is mainly used for hanging wire insulation sub-string (mostly used for straight line tower) and hanging jumpers on insulator string.
2), anchoring tools, also known as fastening tools or wire clamp. This kind of metal is mainly used for fastening the terminal of wire, so that it is fixed on the insulator string of wire resistance, and also used for fixing the terminal of lightning conductor and anchoring the cable. Anchoring fittings bear all the tension of wire and lightning conductor, and some anchoring fittings become conductive body
3) Connecting fittings, also known as wire hanging parts. This kind of appliance is used for connecting insulator string and connecting appliance to appliance. It bears mechanical loads.
4) Connecting fittings. This kind of hardware is specially used for connecting all kinds of bare wire and lightning conductor. The connection bears the same electrical load as the conductor, and most connectors bear all the tension of the conductor or lightning conductor.
5) Protective fittings. This kind of metal is used to protect conductors and insulators, such as pressure equalizing ring for insulator protection, heavy hammer to prevent insulator string from being pulled out, vibration hammer and wire protector to prevent conductor from vibrating, etc
6) Contact with gold fittings. This kind of hardware is used for connecting hard bus, soft bus and outlet terminal of electrical equipment, T connection of wire and parallel wire connection without bearing force, etc. These connections are electrical contacts. Therefore, high conductivity and contact stability are required.
7) Fixed fittings, also known as power plant fittings or high current busbar fittings. This kind of fixture is used for fixing and connecting all kinds of hard bus or soft bus and prop insulator in power distribution device. Most of the fixture fixture is not used as a conductor, but only plays a role of fixing, supporting and suspending. However, as these fittings are designed for high currents, all elements should be free of hysteresis losses.
