Electrical Control Panel

The electrical control panel we developed comprises high/low voltage switchgear, grid-connecting control system, and direct current system. So it can conveniently realize the integration of power generation, grid connecting, power transformation and distribution.

In QNP, you can get the one-stop purchasing service. Here you can get steam turbine, generator, electrical control panel, etc. Besides, uniformed after-sale service experience can be provided. Thus we can save you a great deal of purchasing cost and get excellent service.

We can also provide custom electrical control panel according to your requirements, ensuring our products can cooperate with the other equipment well in your power plant and the whole system works perfectly.
