220kV Power Transformer

220kV three-phase oil immersed on-load voltage regulating transformer brings about a series of major transformations in terms of material, technique and construction. It is characteristic of compact construction, low weight, high efficiency, low loss and low noise, reliability of performance. The product can reduce considerable loss on energy grid and operational costs and extend distinct economic efficacy.

It is suitable for power plant, transformer substation, and large-scale industrial and chemistry factory and etc. the product is according to national and IEC standards.
