S (11) -30~31500kVA Three-phase oil immersed transformer
Three-phase oil-immersed transformers. The transformer body adopts a new type of insulation structure, which improves the short-circuit resistance ability. The iron core is made of high-quality cold-rolled silicon steel sheets. The winding adopts a multi-layer cylindrical or foil structure. All fasteners are treated with special anti-loosening measures. This product has the characteristics of high efficiency and low loss, which can save a large amount of power consumption and operation costs, and has remarkable social benefits.
- Overview
- Recommended Products
The tank adopts a fully enclosed corrugated oil tank structure, which prevents air and moisture from coming into contact with the transformer oil, reduces the degree of oil aging, and prolongs the service life of thetransformer.
The elastic deformation of the corrugated sheets is used to adjust the volume change of the transformer oil due to thermal expansion and contraction.
The product has an outdoor structure, is free of oil stains, and has a high anti-fouling level. During the normal service life, there is no need to replace the transformer oil, and it is truly maintenance-free, ensuring the safe operation and reliability of the power grid.
The transformer is equipped with a pressure relief safety protection. When the pressure in the transformer is too high due to a fault, it can be reliably and safely released through the pressure relief valve to prevent the expansion of the accident.
