10 35кВ масляной ванне силовой трансформатор

3 phase,50--20000kVA,Copper winding IEC,ISO9001,low loss,low noise long service lifetime & safe high quality,reasonable price The transformers are in accordance with National Standards GB1094“Power Transformers”and GB/T6451“Technical Specifications and Requirements for Three Phase Oil-immersed Power Transformers”.The voltage regulation range is 10±4×2.5% kV for 10 kV class and 35±3×2.5%kV for 35 kV class.Voltage regulation is effected by adjusting the on-load tap changer on the high voltage side .Adjustment can be made manually or motor-operated ,and in the latter case automatic regulation is also possible through additional devices ,Such transformers can keep the output voltage on the secondary side at a required stable level .The tank wall of more than 35 kV 3150 kVA transformers is made into a corrugated shape .Thus ,mechanical strength is much improved ,and weldding work reduced ,and the outlook appearance is improved too ,Therefor they are widely used in places where requirment on voltage quality is emphasized ,such as institutes ,building ,hotels,hospital and factories .There transformers are new products and have better economy in operation .
