4/ performance characteristics

1, S9-M series power transformer core USES the high quality cold-rolled steel coil, USES the high quality anaerobic copper into and beautiful outlook, safety of operation. S9 series S7 series transformer and compared, and the annual average no-load loss is reduced by 10% and the average load loss is reduced by 20% and save energy obviously, widely used in industry and agriculture, urban and rural power grid.

2. High reliability, performance level advanced, economical index is reasonable.

3. The core of the level 3 juncture when, surface coating cured paint, in order to reduce loss and noise.

4. Winding new structure, reasonable design oil way, adopt new insulation structure, improve mechanical strength and resistance to short
