Overview

Low voltage switchgear is suitable for industries such as power plants, petroleum, chemical, metallurgical, textile, and high-rise buildings, and is used for power transmission, distribution, and energy conversion. The product complies with the GB7251.1-2013 "Low Voltage Switchgear" (IDT IEC60439-1 1999) standard. Products included in the mandatory 3C certification product catalog.

Product Details

A switch cabinet is an electrical equipment in which the external wires first enter the main control switch inside the cabinet, and then enter the sub control switch. Each branch is set according to its needs. Such as instruments, self-control, motor magnetic switches, various AC contactors, etc. Some also have high voltage and low voltage room switchgear, high voltage busbars, such as power plants, etc. Some also have equipment for protecting the main equipmentLow cycle load reduction.

The main function of a switchgear is to open, close, control, and protect electrical equipment during the process of power generation, transmission, distribution, and energy conversion in the power system. The main components inside the switchgear arecircuit breaker、disconnecting switch、load switchComposed of operating mechanisms, transformers, and various protective devices. There are many classification methods for switchgear, such as the installation of circuit breakers, which can be divided into movable switchgear and fixed switchgear; According to the different cabinet structures, it can be divided into open type switchgear, metal enclosed switchgear, and metal enclosed armored switchgear; According to different voltage levels, it can be divided intoHigh-voltage switchgearMedium voltage switchgear andlow-voltage switchgearWait. Mainly suitable for various occasions such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories and mines, residential areas, high-rise buildings, etc.
