S11 oil-immersed power transformer - Product

Product introduction:

S11-M and S11 series oil-immersed power transformers are new products produced in accordance with national standards. They have compact structure, beautiful appearance, small size, low temperature rise and noise, strong overload capacity, and no-load loss is reduced by more than 30% compared with S9 series products. The no-load current is reduced by up to 45%~80%. It is one of the most energy-saving products produced by our company.

Product features:

The box adopts a fully sealed structure of corrugated oil tank to prevent air and moisture from contacting the transformer, reduce the degree of oil aging, and extend the service life of the transformer; the volume change of transformer oil due to thermal expansion and contraction is adjusted by the elastic deformation of the corrugated sheet.

The product is an outdoor structure with a high anti-pollution level; there is no need to replace the transformer oil during normal use, which is truly maintenance-free and ensures the safe operation and reliability of the power grid.

The transformer is equipped with a pressure release safety protection device. When the transformer fails and the pressure is too high, it can be released reliably and safely through the pressure release valve to prevent the expansion of the accident.

Product sealing form: There are two types of box edge welding and bolt fastening for users to choose.
