This Three-phase oil transformer is an electrical appliance that uses insulating oil as an insulation medium and consists of the iron core, coil, voltage regulating switch, oil tank, etc. It has the characteristics of small size, cheap price, and strong weather resistance. The transformer adopts the core free structure, and all accessories are pre-installed in the factory. Three Phase Oil Transformer is suitable for all kinds of high voltage electrical equipment, power system, industrial and mining enterprises, transportation, post and telecommunications departments, scientific research units and so on.
The transformer is based on the world's advanced technology and integrates the experience of leading international transformer companies and our own long-term experience. With its strong structure and beautiful appearance, it can meet the needs of different users. Also, we can print your logo on our machines for free. If you are interested, please feel free to contact us and we will offer you the best service

Features:
Iron core: All adopt high quality grain-oriented cold-rolled silicon steel sheet, full inclined non-porous binding structure, multi-step ladder core, three-seam or five-seam, low no-load loss, low noise;
Coil winding: It is made of high-quality QQ acylated enameled round copper wire and flat copper wire pulled by the oxygen-free copper rod. Its forms include cylinder type, continuous type, new spiral type, split type, etc. It has enough electrical strength, mechanical strength, and heat dissipation capacity.
Oil tank: It is welded with a high-quality steel plate, with elliptic, rectangular structure, etc., and the heat dissipation element adopts chip radiator, expansion radiator, or corrugated oil tank. The oil tank is tested for reliable sealing in the factory.
