Transformer cores are made of many thin silicon steel sheets or molybdenum-manganese iron sheets laminated together. A thin layer of oxide is formed on the surface of these sheets and this oxide prevents eddy current losses. The construction of the transformer core is very important as it directly affects the efficiency of the transformer.

The high and low voltage winding is wound with epoxy resin in vacuum state. After high temperature curing, it forms a solid whole with good mechanical strength and small partial discharge. Cast resin insulation guarantees secure performance of the transformer with no need for complicated and costly maintenance. Preventive maintenance of cast resin transformers consists in a simple visual check. Low operating costs Low losses in the magnetic core and in the windings reduce the costs of operation. The coils are made with pure copper wire /foil, and encapsulated by high quality epoxy resin.

A radiator is a component that increases the flow of heat from a thermal device. It accomplishes this task by increasing the working surface area of the device and the amount of cryogenic fluid that moves over its enlarged surface area. Finned radiators, as the cooling components of the power transformer and special transformer,are widely used at home and abroad. Our radiator is manufactured by automatically punching, combining, drop sew-welding & edge cutting with high quality cold rolled steel to make the elements. The connection between elements and oil collection pipe apply outside welding(CO2 protecting welding) which has completed solved the problems of welding residue&scrap iron to affect the production quality by applying inner welding. It has alsoexperienced sealing testing,surface treating and hot oil flushing to ensure the product quality. Product tested by the third-party tofully meet the transformer industry standard(JBT5347-99).
