The 10kV S22 series non-excitation voltage regulation distribution transformer is currently the most advanced 10kV distribution transformer product in China. Using a new type of high-conductivity low-loss silicon steel sheet and optimized iron core structure design, the no-load loss is reduced by more than 40% compared with the S13 series, reaching the international leading energy efficiency level.
The fuel tank adopts a fully sealed fuel tank structure, with small oil volume expansion coefficient and good sealing performance, which can realize maintenance-free operation. The fuel tank adopts a corrugated radiator, which has a large heat dissipation area and high heat dissipation efficiency and adapts to different load conditions.
Suitable for 10kV distribution network, residential quarters, industrial parks, rural power grid transformation and other occasions. This product complies with GB/T 6451-2015 “Technical Parameters and Requirements for Three-Phase Oil-immersed Power Transformers”, meets the national first-class energy efficiency standard, and has significant energy saving effect and economic benefits.
