1. According to the function and structure, it can be divided into suspension wire clamps, tension wire clamps, ut wire clamps, connecting wires, connecting wires, protective wires, equipment wire clamps, T-type wire clamps, busbar wires, wire pulling wire clamps, etc. According to the purpose, it can be used as production line hardware and conversion hardware. 2. According to the product unit of power accessories, it can be divided into four parts: malleable cast iron, forging, aluminum copper aluminum and cast iron. 3. It can also be divided into national standards and non-national standards 4. According to the main performance and use of accessories, accessories can be roughly divided into the following categories 1), Suspension hardware, also known as support hardware or suspension clamps. This hardware is mainly used to suspend conductor insulator strings (mainly used for straight towers) and jumpers on insulator strings. 2) Fixing hardware, also known as fixing hardware or wire clamps. This hardware is mainly used to fix the terminals of conductors, fix them on the insulator wires of resistance wires, and is also used for the fixing of the terminals of lightning rods and the anchoring of diagonal wires. The anchoring hardware bears all the tension of the conductor and the lightning rod, and some of them have become conductors 3), connecting hardware, also known as hanging wire parts. This hardware is used to connect insulators into strings and connect hardware and hardware. It bears mechanical loads. 4). Connecting hardware. This hardware is specially used to connect various bare wires and lightning rods. The connection bears the same electrical load as the conductor, and most of the connecting accessories bear all the tension of the conductor or lightning rod. 5). Protective hardware. This hardware is used to protect conductors, insulators, etc., such as grading rings for protecting insulators, hammers for preventing insulator strings from pulling up, and anti-vibration hammers and protective rods for preventing conductor vibration, etc. 6) Contact hardware. This hardware is used to connect hard buses and soft buses to the output terminals of electrical equipment, T-type connections of conductors, and parallel connections without bearing force, etc. These connections are electrical contacts. Therefore, high conductivity and contact stability of contact hardware are required. 7). Fixed hardware, also known as power plant hardware or high current bus hardware. This kind of hardware is used to fix and connect various hard busbars or soft busbars and post insulators in power distribution equipment. Most of the fixing hardware is not used as a conductor, but only for fixing, supporting and hanging. However, since these accessories are used for large currents, all components should be free of hysteresis loss.
