Dry Type Electrical Transformer
Dry Type Transformer are fitted in enclosure for Indoor installations and are totally maintenance free and safe from fire as the material used is metal, ceramic, and resin.
It is environment friendly as there is no oil, hence handling becomes easier and there are no chance of spillages and leakage and there is minimal nontoxic smoke in case of fire. Use of Class F/H insulation increases the heat bearing capacity and enables the use of the transformer in humid and chemically polluted atmosphere also.
- Fire safety and environmental aspects are of increasing importance.
- The substitution of oil filled transformers by dry type transformers is one of the most important steps towards it.
- Dry Transformer is used when it has to be located near load centre and in a fire hazardous place.
- Special type of fire resistant insulation is used for the windings, thus reducing the fire risk considerably.
