    S11, 10KV low-loss power transformer instructions

    S11, 10KV low-loss power transformers execute national standard GB1094 "power transformer" and GB/T6451 "technical parameters and requirements of three-phase oil immersed power transformer".

    S11 is a three-phase oil immersed R type, step type coil core distribution transformer. The inside and outside frame of the ladder type three-column frame structure, all in the outermost spot welding without binding. The core material is made of cold-rolled silicon steel sheet with dq133-30 (type 9), 30ZH120 (11) and 23ZH90 (type 13). The iron core material used in actual production is not lower than the design requirement. The core is continuous rolling without joints. R type iron core sheet width ensures that the core section is round, and the staircase core is made of multistage sheet width. After the iron core is formed to vacuum annealing, the stress is eliminated and the loss is reduced.

    S11, 10 kv level low loss seal corrugated tank structure is adopted for power transformer, transformer oil and the surrounding air do not contact, so the transformer oil will not absorb moisture, and will not reduce the dielectric strength; In addition, the oxygen cannot enter the fuel tank, thus avoiding the aging of insulating materials, improving the service life of the product, and improving the social benefits.

    Technical features

    Energy saving: the S11 model is 30% lower than GB/T6451, and the load loss is reduced by 25% on average, and the running cost is reduced by 20%.

    Long service life: full seal structure is used in transformer oil tank. The fuel tank and box are joined or welded along the available bolts. The oil of transformer is not connected with air to extend the service life.

    High reliability: the oil tank seals the parts for improvement, improves 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.
