1.Its iron core is made of cold-rolled silicon steel sheet in high quality and adopts the
struture of miter  joints without perforation.

2.Coil appears good-looking and operates safely, is made of high quality oxygen-free
copper, and is wide used in urban and rural power transmission and distribution.

3.Fuel tank is corrugated sheet type or expansion- type radiator tank. It reduces the
transformer height  because it is no need of oil conservator. Oil is isolated from air,thus
it extends the service life of the transformer.

4.Performance features

   1)The iron core is made of high quality cold-rolled silicon steel sheet with the
orientation of high  permeability crystal grain and adopts the struture of miter joints
without perforation. The circular section of the iron core is multistage cascade structure.

   2)The high voltage winding has taps corresponding to the requirements of the tapping
voltage. Switch is mounted on the tank cover. The tapping voltage is converted when the
power supply is cut.

   3)The transformer is equipped with oil level gauge to indicate three oil-level marks of
-25℃,20℃ and 40℃  when the transformer is operating.
