Power⁺ F | Indoor SF6 3.3kV to 11kV

The Power⁺ F are an Indoor SF6 Switchgear Panels of voltage range 3.3kV to 11kV and current ratings from 1250A to 3150A.

Outdoor Panels are of Kiosk Type construction with double doors in the front. The Rear door that is both hinged and bolted for safety. Robust weather and dust proof IP55 degree of protection externally and IP2X between compartments.

We believe in shorter lead times and faster response for our product customisations.
