Abstract
An oil-filled pole-mounted distribution transformer comprises a tank housing a transformer core-coil assembly immersed in cooling oil. The tank is made of a corrosion-proof composite material and a radiator is provided for cooling the oil. The radiator is external to the tank and has a hot oil inlet and a cool oil outlet located at different levels into the tank for causing a natural circulation of oil through the radiator by thermal siphoning.
