Product Information

Ggd/Ggj Low Medium Voltage Metal OEM ODM Enclosed Withdrawable Electrical Substation Switchgear
High/Low voltage switchgear refers to the electrical products used for power system generation, transmission, distribution, power conversion and consumption to play the role of on-off, control or protection, voltage level in 3.6kV~550kV, mainly including high/low voltage isolation switch and ground switch, high voltage load switch, high voltage automatic recirculation and sectioner. High voltage operating mechanism, high/low voltage explosion-proof distribution device and high voltage switchgear and other categories.
The switchgear has the functions of overhead inlet and outlet line, cable inlet and outlet line, and busbar connection. It is mainly used in power plants, substations, petrochemical industry, metallurgical steel rolling, light textile industry, factories and mining enterprises, residential areas, high-rise buildings and other different places.

The high and low voltage switchgear is an important part of the power system, which is mainly used to break the circuit, protect the power equipment and control the power system. The following is the main role of high and low voltage switchgear:

1. Disconnect the circuit

The high and low voltage switchgear can successfully perform the switching operation of the circuit breaker, that is, the switchgear can separate or connect the power supply by controlling the switch, and ensure the continuity of power transmission while maintaining the safety of the circuit and equipment.

2. Protect power devices

In the power system, the transmission process of high-voltage power supply will produce various faults, such as overload, short circuit and ground fault. The high voltage switchgear can choose the appropriate protection device according to the actual situation, detect and deal with these faults in time, and ensure the normal operation of the power equipment.

3. Control the power system

The high and low voltage switchgear can control the switch and state of the power equipment according to the actual needs of the power system. For example, when controlling the power system in real time, it is necessary to precisely adjust the transmission and distribution of power, and the high and low voltage switchgear can achieve this by controlling the switch.
