Product Description

110KV/66kV series power transformer

Product description

66kV oil immersed on-load voltage regulation power transformer has a series 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 operable operation which cutting down large number of loss from energy GRID and minimizing 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.
