Types and Classification Description of Electrical Fittings
1. Introduction to what is power fittings:
Iron or aluminum metal accessories widely used in power transmission lines are collectively called power fittings. There are many types of hardware with different uses, such as various clamps for installing wires, various hanging rings to form insulator strings, various crimping tubes and repair tubes for connecting wires, and various types of spacer rods for split wires. etc. In addition, there are various types of wire-staying hardware used in pole towers, as well as the size of the protective wires, which must cooperate with each other.
2. Types and functions of electrical hardware:
1. Connecting hardware, which is used to connect insulators into strings and to connect hardware to hardware. It bears mechanical loads.
2. Suspension fittings, also known as suspension clamps/suspending fittings. This kind of hardware is mainly used to hang wire insulator strings and jumper insulator strings.
3. Tension-resistant hardware, also known as fastening hardware or anchoring hardware. This kind of hardware is mainly used to fasten the terminals of wires and fix them on the wire-resistant insulator string.
4. Protective hardware, which is used to protect wires, insulators, etc. (Such as: anti-shock hammer, pressure equalizing ring, protective strip, etc.).
5. Connecting hardware, which is specially used to connect various wire accessories.
6. Fixed hardware, which is used for fixing and connecting various busbars and pillar insulators in power distribution devices.
3. Summary of power hardware:
Through the above articles, we have learned that power fittings are metal accessories that connect and combine various devices in the power system, and serve to transmit mechanical loads, electrical loads and some protective functions. In addition, most fittings need to withstand large pulling forces during operation. , some also need to ensure good electrical contact, which is related to the safety of wires or towers. Even if one is damaged, it may cause line failure. Therefore, the quality, correct use and installation of hardware have a certain impact on the safe power transmission of the line.
