SANERGRID is the French representative for cast resin transformers from european leader manufacturer Trafo ELETTRO.

The objective of a dry-type transformer (as opposed to a standard oil-type transformer) is to offer an increased level of fire safety while ensuring total reliability in service.

Dry-type transformers thus provide increased protection for people and the environment with reliability comparable to that of transformers immersed in standard mineral oil.

In case of space problem related to the respect of the NFC13-200 concerning the fireproof trays for oil transformers, the coated dry transformers are not subjected to this requirement what facilitates their installation.
