Windings are cast with epoxy resin mixtures to present high withstand strength against harsh environment, non-explosion features, and increased mechanical strength. With the advantages of light weight, compact size, and easy maintenance, Sanil cast resin transformers are used for commercial buildings, hospitals, airports, industrial plants and large ships

Cast resin type auto transformers are used for railway substations to serve AC rail loads.

AFWF cast resin transformer is equipped with heat exchanger for cooling by forced air and liquid circulation. Approximately 90% heating losses are absorbed in coolers, which reduces size and weight of the transformer by 30% compared with transformer of AN cooling method

Marine cast resin transformers supply electricity for internal loads of ships such as lightings, electric motors and mooring. Marine cast resin transformers are designed to withstand fluctuating loads, vibration and provide for easy installation in a limited space.
