Power transformer, dry type transformer, distribution transformer
SG(C)10 series grade C insulated unsealed coil dry type transformer, which is exploited firstly by our company, is a new kind transformer with the advantages of low loss, high efficiency, safety and environmental protection according to the demand of Chinese power market, the limit of using location and regular over-load of transformer. It combined the techniques of Mora in Germany and dupont in American SG(C) 10 filled the blank of national dry type transformer market and has obtained the national patent already. (patent No: 20042002633.8).

Functional characteristics
1. Good heat emission, big overload capacity. Can work without wind machine for long time under 130 overload, and be full load without compulsive wind cool without capacity descending under IP45 condition
2. Perfect safe and resistance to fire operating can be combusting for long period under 800º C and without smoke
3. Strong resistance to thermal shock(can be full load immediately at -50º C)
4. Complete waterproof and airproof
5. No partial discharge
6. Good hydrophobility and good resistance to alkaline cauterization and fundal influence
7. Environmental, low noise, no deleerious gas, easy to decomposition
