Product Detail

Structural features

S11-M series oil-immersed transformer adopts high quality grain orientation cold rolled silicon steel sheet iron core, all inclined non-hole binding structure, the iron core is multi-level step shape, three joints or five joints, low air loss, low noise; Coil: the use of high quality QQ lacquer coated round copper wire, oxygen free copper rod drawn flat copper money or copper knot wound.its form has cylinder type, continuous type, new screw type, split type, etc., with enough electrical strength, mechanical strength and heat dissipation capacity. Fuel tank: The use of high quality steel plate welded, elliptic, rectangular and other structures, cooling elements using chip radiator,expansion heat dissipator or corrugated oil tank, the tank in the factory for reliable sealing test,the internal and external surface after pickling, phosphating treatment, three bottom side paint coating, both corrosion resistance and beautiful.
