66KV~110KV Power Transformer - SFL Transformer

66KV~110KV Power Transformer

110kV three-phase oil-immersed on-load voltage regulating power transformer has adopted a series of major reforms in material, technology and structure. It has the characteristics of small size, light weight, high efficiency, low loss, low noise and reliable operation. It can reduce a large number of power network losses and operating costs, and has remarkable economic benefits.

66kV class power transformer has adopted a series of major reforms in material, technology and structure. It has the characteristics of small size, light weight, high efficiency, low loss, low noise and reliable operation. It can reduce a lot of power network losses and operation costs, and has remarkable economic benefits.

It is suitable for power plants, substations, large-scale factories, mineralization enterprises, etc.

Application range
Mainly applicable to substations, coal mining enterprises, petroleum enterprises, solar power generation, wind power generation and other important places with special requirements.
