2 MVA 11/0.4 KV Transformer Winding
The functions of transformer winding
The primary wind brings the electric energy of the system into the transformer, while the secondary wind transfers the electric energy out, so the wind is the main component of the transmission and conversion of electric energy.

Transformer knowledge
What is adjustable capacity transformer?
Regulating capacity transformer is a kind of energy-saving transformer specially used in rural areas. It can change the capacity of transformer by changing gear operation, to meet the different needs of rural peak power consumption and low power consumption in slack season. Therefore, it can greatly save electric energy and is a kind of agricultural transformer that should be vigorously promoted.
