Power Transformer (According to IEC)

SR11series wound core transformer
This Series product's iron core adopt low-loss high-quality silicon steel sheet, so the transformers have of energy-conserving environmental protection, no need to cut then no cut holes left, so it can dispel the horizontal, vertical seam that the traditional iron core has, decrease loss of magnetism. Utilize orientation of silicon steel sheet fully, dispel the may increased loss of finished product because magnetism way not in accordance with orientation of the silicon steel sheet, it is the substitute of distribution network;
Low loss: Off-load loss decreased about 30%-45%, off-load current decreased about 80%;
Low noise: Decreased 7-10dB
Voltage 35kV oil-immersed transformer
This series of products are on the basis of digesting, absorbing domestic advanced technology, through optimizing innovation, the new products with the high-tech are remarkable in material saving & loss reduction, have stronger competitiveness in the market
It's section cut straight in multistage round, full miter jointing. Adopting the new craft of two pieces three-grade and going forward one by one overlapping. The new technology's using make no load loss lower 8-10% in average. It save energy remarkably.
The main and vertical insulation of the body of Transformer is re-designed on the basic of electric field calculation model test and absorbing successful experience at home and abroad. It increase the ability of resisting short circuit effectively.
Voltage 110kV full sealed free -maintain power transformer
