Sunel breakthrough new technology,dry type transformer china,transformer let promotion Sunel new transformer co., LTD dry type transformer distribution transformer has accounted for 40 to 50%. In China, about 50 percent, based on historical experience and transformer voltage level of structural changes in distribution transformer ratio is about 40%, in accordance with the proportion of 40%, this years Chinese New conservatively estimated distribution transformer production will reach 846 million KVA; while the proportion of 20-25% by count, dry type transformer cooling performance, overload capacity, forced air cooling can increase the capacity to run, using advanced technology, high mechanical strength, resistance to short-circuit capability, partial discharge , good thermal stability, high reliability and long service life. Sunel new transformer co., LTD dry type transformer temperature control system using intelligent signal can automatically detect and display the three-phase winding roving respective working temperature, it can automatically start and stop the fan, and alarm and trip settings and other functions, both in the factory scale, the product capacity, voltage, etc. have a world leading level.
