Definition of Electrical Hardware

The GB/T5075-2001 standard "Terminology for Electric Power Hardware" defines electric power hardware as metal accessories that connect and combine various devices in the power system, serving to transmit mechanical and electrical loads as well as providing protection.

Hanging accessories, support hanging accessories, or support hanging clamps. These hardware items are primarily used for emitting multiple guide wire clamps on overhead transmission towers and insulator strings for ascending jumper wires. Such electrical fittings are mainly employed to secure the terminals of electrical wires and cables onto insulator strings, and also for fixing lightning rod terminals and anchoring tension cables. Anchor fittings bear the full tension of conductors and lightning protection cables, with some anchor fittings also serving as conductors. They connect accessories and hanging nodes. Fittings are used to connect connectors in series and to link fittings with other fittings. Other mechanical equipment. Connection accessories. This type of electrical fitting is specifically designed for connecting various exposed protective wires and lightning protection lines. They connect lines with the same tensile strength as the supporting cables, as well as all supporting cables for fittings or lightning protection lines. Hardware. These electrical fittings are used for protection and insulation, such as voltage equalizing rings used to protect insulators, heavy weights to prevent the lifting of insulator strings, anti-vibration weights to prevent signal vibration, and so on.

Fixed hardware, also known as power station hardware or high-current busbar hardware. This type of hardware is used for the fixation and connection of various hard or soft busbars and a small number of insulators in distribution equipment. Fixed accessories are generally not the main components, but serve to fix, support, and suspend. However, due to their use in high currents, all components should have no lag losses. Contact hardware. Hardware used to connect the hard busbars, soft busbars, and terminal ends of electrical equipment. This includes T-type wire connections and stress-free parallel connections. These connections are electrical contacts. Therefore, the conductivity and stability of the contact hardware are required.
