dry-type cast resin transformers have been shown to reduce this risk. Since they do not contain petroleum, they greatly reduce the risk of fire. They are also rated F1 in terms of fire protection standards. This means they will not cause a fire under short circuit conditions and are inherently fire resistant.

A transformer is a static electrical appliance that converts ac energy of one voltage class into AC energy of another voltage class of the same frequency by means of electromagnetic induction between coils. The transformer works on the principle of electromagnetic induction and consists of two windings that are insulated from each other and have unequal turns.
