Product Description

Product Features

Oil immersed transformer ,use Japanese Toshiba analysis software and our company special calculation and validation procedures to make sure the performance of products. Superior process equipment ,elaborate material selecting and efficient manufacturing make the transformer have small volume,light weight,low loss,low partial discharge,low noise characteristics.

The product is stable,reliable,economic, environmental protection.It can be applied to many places such as power plants,transformer substation ,large industrial mining and petrochemical enterprise and so on.

Structure Characteristics

Reliable structure
Depending on mature technologies, we made a lot of improvements on the basis of traditional structure:

Spiral winding with longitudinal oil duct that enjoys good inner heat dissipation;

Effective support at winding end surface that further improve the short-circuit resistant capacity of winding;

Adoption of new hoisting structure and body positioning structure that guarantee safety in long-distance transport and in service;

More unique and reliable structure for your option;

Adoption of transformers with more excellent performance  to improve the technical content.

Excellent materials
Because we use oxygen-free copper wires of lower resistivity, which will become smoother and burr-free after a series of surface treatment, so the load of our transformer is lower and the electric performance is better.
We use high quality silicon-steal sheets which are of lower specific loss, so the no-load loss of the transformers is lower.
We use high quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit current.
We use thoroughly filtrated transformer oil containing less water, gas or impurities, which makes our transformer work better.
We use high quality rubber sealing material, which can prevent the transformers from aging or leakage effectively.
All raw materials have passed the quality testing, and all the raw factories have passed the national standard ISO9000 inspection.

Good technology and economic performance
Improved from S9 series product, S11 series product reduces the no-load loss by 31%; no-load current by 75-90%; average temperature-rise level by 3-5 db; and double the products' service life. Even under 20% overloads, it can also work for a long period of time.

Hermetically sealed
The "M" in S11 (M) stands for omniseal structure that the oil tank employed. Compared with common oil-immersed transformer, omniseal oil-immersed transformer discards the oil conservator but adopts wing-likes corrugation for replacing oil tube as component of heat dispersion. The corrugated oil tank which is made of high-quality cold-rolled sheets is produced on the special production lines. The wing-like corrugation will expand and compress as that volume of transformer dose, so that the transformer is separated of operation and atmosphere and can prevent or slower deterioration of oil and breathing of insulation. All these ensure the reliability of operation and without maintenance.

After the treatment of dealing, derusting and parkerizing, the surface of corrugated oil tank is coated with paint which provides three-proofing function, it is suitable for the use in the environment such as metallurgy, petrochemical industry and mining, etc.
