S9, S10, 35KV low loss power transformer instructions.

S9, S10 and 35KV low-loss power transformers are three-phase oil-immersed R type, step-type coil core distribution transformers.

The ladder type three column inside and outside frame roll structure, all in the outermost spot welding do not bind.

The core materials are cold-rolled silicon steel sheets, such as dq133-30 (type 9), 30ZH120 (11) and 23ZH90 (type 13). The core materials used in the actual production are not lower than the design requirements.

The core is continuous rolling without joints.

The core section of R type iron core is round, and the step type core is made of multistage wide roll.

After the iron core is formed, vacuum annealing is carried out to eliminate the stress and reduce the loss.

The integrated, S10, 35 kv level low loss power transformer with fully sealed corrugated tank structure, transformer oil and the surrounding air do not contact, so the transformer oil will not absorb moisture, thus will not reduce the dielectric strength;

In addition, the oxygen cannot enter the tank, thus avoiding the aging of insulating materials, improving the service life of the product, and improving the social benefits.

Technical characteristics

Energy saving: the 35KV level is 30% lower than GB/T6451, and the load loss is reduced by 25% on average, and the operating cost is reduced by an average of 20%.

Long service life: complete sealing structure is adopted in the transformer oil tank. The fuel tank and the box can be connected or welded along the available bolts. The transformer oil does not extend the service life with air contact.

High operational reliability: the fuel tank seals the relevant parts for improvement, increases the reliability, and improves the process level to ensure the reliability of the seal.

Cover an area of an area small, the integrated M, S11 M series transformer with corrugated tank type radiator, when the oil temperature change corrugated plate heat bilges cold shrink can replace the role of oil storage tank, corrugated plate tank of beautiful shape, cover an area of an area small.
