They are widely used in various fields such as industry, construction, transportation, and energy, and are crucial for the safe and stable operation of electrical systems. Electrical accessories are diverse, but mainly include the following categories:
Cable Trays: Used to support and protect cables, preventing mechanical damage or environmental corrosion. Common cable tray types include ladder-type, tray-type, and trough-type, and are mostly made of steel or aluminum alloy, featuring high strength, rust resistance, and corrosion resistance.
Terminal Blocks: Used for electrical connections, facilitating the fixing and conduction of wires or cables. Terminal blocks come in various types, such as plug-in type, screw type, and spring type, suitable for different current and voltage levels.
Circuit Breakers and Switches: Used for connecting, disconnecting, and protecting circuits. Circuit breakers include air switches and residual current devices (RCDs), which automatically disconnect the circuit in case of overload or short circuit, ensuring safety.
Distribution Boxes and Meter Boxes: Used for centralized management and distribution of electrical energy, typically installed in buildings or industrial equipment. The distribution box can house circuit breakers, meters, and other equipment for easy maintenance and management.
Insulation materials: such as insulating tape and sleeves, used to isolate conductive parts and prevent short circuits or leakage. Insulation materials must possess good high-temperature resistance and aging resistance.
Grounding devices: such as grounding wires and grounding rods, used to conduct leakage current from electrical equipment to the earth, preventing electric shock accidents.
Cable joints and terminations: used for connecting and terminating cables, ensuring the cable's sealing and electrical performance.
Electrical installation accessories: such as cable clamps, cable ties, and mounting brackets, used for fixing and installing cables and equipment.
