6kV(10kV) Mine Explosion-proof And Intrinsically Safe High Voltage Motor Soft Starter

Short Description:

With the application of large equipment such as ventilation fans, pumps and belts in coal mines, there is an urgent need for a product that can reduce the current in the motor starting process, smooth starting, and ensure the safety of the motor and related equipment. Coal mine bottom and surrounding medium contains methane, coal dust and other mixed gas, this special occasion, it is necessary to use mine flameproof soft starter.

Explosion-proof motor soft starter is a product specially developed for coal mine environment based on many years of soft start design, development and application experience.
