Special control cabinet for submersible electric pump and integrated pry installation of transformer.

 

The special control cabinet for submersible electric pumps provides 8 safety protections for the submersible pump. When the submersible electric pump suddenly stops it can save the three-phase voltage, three-phase current and control voltage data at the moment of shutdown, and can transmit it to the computer.


Based on the different voltages required by the submersible electric pump: there are low-voltage control panels and medium-voltage control panels.
