Product Overview
The GKD type mining low-voltage switchgear is a draw out type switchgear that has obtained the mining product certificate and safety mark certification. It is suitable for various mining areas, including coal mines, non-coal mines and other similar underground industrial production departments where there is no gas or coal dust explosion hazard. Suitable for AC50Hz power supply systems with rated operating voltage of 660V and 380V and rated operating current up to 3200A, it is used for energy conversion and distribution control of power, lighting and distribution equipment, enabling motor starting and lighting supply. It can also serve as a rectifier cabinet for traction locomotives and a DC power cabinet for underground substations. Equipped with a leakage protection unit, it is suitable for underground use.

FAQ
Q: What is the GKD switchgear?
A: The GKD is a mining low-voltage draw out type switchgear suitable for coal mine underground environments.
Q: When should the GKD be selected?
A: It is recommended when the distribution site is an underground environment (without gas or coal dust explosion hazard) in coal/non-coal mines and motor control, lighting supply or DC power is required.
Q: What is leakage protection?
A: A protection device that automatically cuts off the power when insulation failure causes leakage current exceeding the set value, preventing electric shock and electrical accidents.
