Dry Type Transformer

Unlike their liquid-filled counterparts, dry-type transformers do not incorporate liquid to dissipate excess heat and meet temperature classification requirements. Instead, the coils within a dry-type transformer are constructed of a gaseous or dry insulation medium.

Low-voltage dry-type transformers (LVDT) are generally used inside buildings to reduce voltage to the values necessary to power appliances, lighting and other products. Unlike liquid-immersed transformers, these are generally owned by the building owner.
