Overview
China 110/66 kV power transformer manufactured by Rockwill with a low price and good quality. Supporting customization. It has exported to many countries like South Africa, Mozambique, Tanzania, Uganda, Ethiopia, etc.
Product Details
have adopted series of important reforms on the 110kV level three-phase oil-immersed on-loadtap changing transformer referring material, process and structure. The transformer has the features of small size, light weight, high efficiency, low loss, low noise, reliable operation etc. which can reduce a large amount of power network loss and operation expense with significant economic benefits. It is suitable for power plant, substation, heavy section plant or enterprises etc.
