66KV level S(F)9, S(F)10, S(F)11 3-phase transformer with no-load tap changer

Product description

　　110KV oil immersed on-load regulation power transformer has a seires of big changes in material, technical and construction with the characters of small size, light weight, high efficiency with low loss and low noise, stable opable operation which cutting down large number of loss from energy GRID and minising operation charge, improving the industrial economic benefit. It is used in power plant, transformer substation, big-sized and chemistry factory and etc. The product is according to National and IEC standards.
