Product Information

Specification

Also known as:

Single-Phase Transformers, Pad-Mounted Transformer, Power Distribution Solutions, Oil-Immersed Technology.

About:

Pad-mounted transformers for solar applications have their active part immersed in dielectric oil and use dead-front terminals, which means they do not have exposed energized parts and are located inside a cabinet, with safety-sealed compartments, with doors and locks. both for the low voltage side and for the high voltage side, which makes it a very safe device. In addition, the pad mounted transformer has built-in connection, protection and maneuver elements typical of a substation that protect the equipment.

Notes: This product can be customized as per customer requests.
