Performance Characteristics

●Compared with S11 type transformer, the no-load loss of this series is reduced by about 30% on average.

●Capacity in the range of 630~2000kVA low-voltage winding adopts cylinder or spiral structure, high mechanical strength, ampere-turn distribution balance, the product of short-circuit resistance is good.
The short-circuit resistance of the product is good.

●The body of the product is equipped with additional positioning structure so that it does not shift during transportation, and all the fasteners are equipped with fastening nuts to ensure that the fasteners do not loosen during long-term operation.
●Meanwhile, all fasteners are equipped with fastening nuts to ensure that the fasteners will not loosen during long-term operation, which meets the requirement of not lifting the core.

●The transformer adopts corrugated oil tank, eliminating the oil storage cabinet, and the cover and the edge of the tank are completely welded or bolted, prolonging the service life of the transformer oil.
●The surface of the product is degreased, descaled, phosphatized and then sprayed with primer and top coating, which can meet the special requirements of metallurgy, petrochemical system and humid and dirty areas.
The products can meet the special requirements of metallurgical and petrochemical systems and humid and dirty areas.

●Selected components, fully sealed transformer tanks, pressure relief valves, signal thermometers, gas relays, etc. are installed according to standard requirements to ensure the safe operation of the transformer.
This series of products has a beautiful appearance and small volume, ensuring the safe operation of the transformer.
●This series of products have beautiful appearance, small volume, can reduce the installation area, is the ideal maintenance-free high-quality products.
