POWER TRANSFORMER
35kV transformers of S9, S11 and S13 series are manufactured in conformity with IEC60076 standards (applicable International Electrotechnical Commission standards), GB1094 standards (applicable state standards of the People's Republic of China) and GB/T6451 “Technical Parameters and Requirements of Three-Phase Oil-Immersed Power Transformer”.
The voltage range of on-load & offloading voltage regulation is 35±2*2.5%kV, 38.5±2*2.5%kV, 35±3*2.5%kV and 38.5±3*2.5%kV. The voltage can be adjusted manually, electrically or automatically at the primary voltage side within the specified range with the help of on-load
tap changer.
35kV transformers with above 10000kVA capacity are equipped with folded plate structure oil tanks, which increase the mechanical strength, decrease welding joints, and improve the appearance quality of transformers. It is a new generation of product and it has high economic effectiveness.
