3/ carries out the standard

1. IEC60076 power transformer   distribution transformer

2. GB1094.3, 5-2003 power transformer

3. GB/T6451-2008 oil-immersed three-phases transformer power technical parameters and requirements

4. GB1094.1 ~ 2-1996 power transformer

4/ performance characteristics

1, S11 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. S11 series S9 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
