oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding

The three-phase oil-immersed distribution transformer produced by our company uses a new insulating structure to improve the ability to withstand short-circuits. The iron core is made of high-quality cold-rolled silicon steel sheet, and the windings are made of multilayer cylinder or foil structure. All of fasteners use special anti-loose treatment.
The product has the characteristics of high efficiency and low loss. It can save a lot of power consumption and operating costs and also has significant social benefits. It is the national high-tech products.

Features of Products
1 The body adopts a new type of insulation structure to improve the ability to withstand short-circuits;
2 Spiral coil with longitudinal oil passage has a better internal heat dissipation;
3 High efficiency, low loss, can save a lot of power and operating costs;
4 The surface of the corrugated oil tank is coated with three anti-paint after oil removal, rust removal, and phosphating. It is suitable to use in metallurgy, petrochemical, and mining environments.

Material

Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short circuit.
Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
High-quality rubber sealing material, which can prevent the transformers form aging or leakage.

·working conditions
