The is a new oil immersed type transformer that constructed with newest core material and optimized structure design, which can greatly decrease the no load loss of the traditional type transformer. It used single wave silicon steel sheets and high-precision winding process for outstanding electric property and energy saving.
The transformer is filled with top-grade insulating oil with high thermal conductivity and dielectric strength. It is suitable for various load conditions in the field of operation. Its sealed tank has blocked-out effect to inhibit the oxidation of its oil and no absorption of moist air, resulting in lower costs and longer life.
S13 transformers are important small power distribution devices. They are often used at electric power plant, substation, industrial, commercial and infrastructure applications in a power network. Excellent overload ability, low temperature rise, and reliable short-circuit strength make them an ideal choice for time-saving and efficient power distribution.
