S9-50KVA 11KV/0.4KV three phase oil immersed power transformer

1.Certificate:CCC,CTQC,ISO9001,ISO14001,OHSAS18001 2.Apply for IEC,ANSI 3.oil immersed power transformer 4.5 years warran

The three-phase oil-immersed distributing transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made up of cold-rolled silicon-steel plate of high-quality. high voltage winding group is made up of high-quality oxygen-free copper liner lines and it adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent As high-tech product that promoted by the country, the product has many advantages such as high efficiency, low loss, its social benefits are remarkable that it will save much of electricity consumption and operating cost.

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
