Performance characteristics 

♦ Compared with the S9 transformer, the no-load loss of this series is reduced by about 30% on average.

♦ The low voltage winding with capacity in the range of 630~2000k VA adopts simple or spiral structure, mechanical strong base height, balanced ampere-turns distribution, and good anti-short circuit ability of the product.

♦ The body is added with a positioning structure, so that it does not displace during transportation, and all fasteners are installed with fastening nuts to ensure that the fasteners are not loose during long-term operation and meet the requirements of no core.

♦ Transformer adopts corrugated oil tank, cancels the oil storage tan k, the cover and the edge of the box are completely welded or bolted, prolongs the service life of the transformer oil.

♦ fter oil removal, rust removal and phosphating, the product surface is sprayed with primer and top paint, which can meet the special requirements of metallurgy, petrochemical system and wet and dirty areas.
