Cast resin transformers are constructed with their HV windings encapsulated in resin , Apart from being oil-free, all components of dry-type transformers are in solid form; they do not have flash points, nor do they require bushings. Thus, major causes of fire and oil-spillage are eliminated. Moreover, the total cost of ownership for dry-type transformers is much lower due to lower cost of installation and no need of fire suppression system.
