Pad Mount Transformer

Pad mount Transformers

With the maximum demand of pad mount transformer in the European cities & all over the world. We Balaji Power Automation introduce of launching series of pad-mount transformer.

We manufacture pad transformer as per IS 2026, IS 6600, IEC 60076, ANSI & IS 1180 standards.

RANGE : Upto 10 MVA in 46,000 Class.

What is Power Transformer?

padmount or pad-mounted transformer is a ground mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad. Since all energized connection points are securely enclosed in a grounded metal housing, a padmount transformer can be installed in places that do not have room for a fenced enclosure.

Pad-mount transformers are available in various electrical and mechanical configurations. Pad-mount transformers operate on medium-voltage distribution systems, up to about 35 kV. The low-voltage winding matches the customer requirement and may be single-phase or three-phase.
