S20 transformer refers to oil immersed transformer, S is three-phase, 20 is transformer performance level code, M represents fully sealed, KVA represents the rated capacity of the transformer, 10/0.4 refers to the rated high voltage side of the transformer being 10kV and the low voltage side being 0.4kV.

-Can solve the problems of large capacity heat dissipation and high voltage insulation in transformers;

-High reliability, impact resistance, anti-interference, lightning protection, able to adapt to various harsh outdoor environments;

-Transformer oil has good insulation performance, good thermal conductivity, and is cheap and cost-effective;

-The use of high-quality cold-rolled silicon steel sheets for lamination has the advantages of high magnetic conductivity and low loss.
