Overview

The dehumidification series products developed by our company can solve the condensation and moisture problems effectively in operation of all indoor substation equipment. The situation would be in the substation distribution room, high-voltage switch cabinet, low-voltage switchgear of outdoor, terminal box, etc. It prevents conduction or insulation accidents caused by long-term high humidity operation of the substation equipment.
