In power systems, hardware fittings are parts used to fix and connect electrical equipment. Its main function is to ensure the stable installation of insulators, wires and other electrical components, thereby reducing safety hazards such as leakage and short circuits, and improving the reliability and safety of the overall system.

The design and selection of hardware fittings are crucial to the operation of power systems. They need to have multiple characteristics such as high strength, corrosion resistance, and high temperature resistance to adapt to working conditions in different environments.
Hardware fittings generally refer to mechanical parts used to fix insulators, connectors or electrical components. These fittings can be clamps, locking bolts, clips or other types of supporting structures, and their purpose is to ensure the stability and safety of the equipment.
In power systems, hardware fittings are widely used in high-voltage equipment, distribution systems, control panels and other parts. For example, in high-voltage switchgear, hardware fittings are used to fix key components such as insulators and circuit breakers; in distribution boxes, hardware fittings are used to connect wires and protective devices.
Hardware design and material requirements
The design of hardware fixtures must meet specific standards and technical requirements to ensure their reliability in different environments. Here are some common design standards and material properties:
ANSI B70-2018 standard
This standard is a guiding document for the safe design of high-voltage equipment developed by the American Institute of Electrical Engineers (ANSI). According to this standard, hardware fixtures must have high strength, corrosion resistance, and anti-loosening properties.
Material properties
The materials of hardware fixtures are usually made of plastic, polyamide (PA) or magnesium oxide insulation materials. These materials have good mechanical strength, insulation properties and high temperature resistance, which can meet the needs of power systems.
Design requirements
The design of hardware fixtures must take into account the impact of factors such as ambient temperature, humidity, and vibration on the equipment. For example, in a humid environment, hardware fixtures need to have moisture-proof functions; at high temperatures, high-temperature resistant materials need to be selected.
Types and applications of hardware fixtures
Hardware fixtures can be divided into the following types according to their uses:
Clamps
Clamps are used to fix insulators and wires. For example, in a distribution box, clamps can be used to fix wire terminals and connectors.
Locking bolts
Locking bolts are used to connect the two ends of the equipment to ensure that it is firmly installed. In high-voltage switchgear, locking bolts are an indispensable key component.
Clips
Clips are used to fix wires and protective devices. For example, in a control panel, clips can be used to fix power lines and ground wires.
Support structures
Support structures are used to fix key components such as insulators and circuit breakers of high-voltage equipment. These structures are usually made of metal or composite materials and have good strength and durability.
Importance of hardware fixings in power systems
The role of hardware fixings can be summarized as follows:
Ensure the stable installation of equipment
Hardware fixings can fix insulators, wires or other electrical components in a specific position to prevent loosening or movement, reducing safety hazards.
Improve system reliability and safety
By using high-quality hardware fixings, the incidence of equipment failures can be reduced and the normal operation of the power system can be ensured.
Adapt to complex environments
The design of hardware fixings usually takes into account complex environmental conditions (such as humidity, high temperature, etc.) and can meet the needs of the power system.
