GB/T********9 Technical parameters and requirements for three-phase oil-immersed power transformer

Performance characteristics:
1. The features of this product are high efficiency and low loss. It can save a lot of operation cost, and the social benefits are very significant.
2. The iron cores are made of the imported high-conduction magnetism, cold-roll, and grain-oriented silicon-steel sheets. The iron cores and windings adopt the vacuum drying and vacuum oil-filling processes, which make the internal moisture down to the very low level.
3. The conservator is hermetically sealed, which make the internal running oil to insolate with oxygen and moisture efficiently.
4. The above features guarantee the transformer does not need to replace the oil during the normal operation, greatly decrease the maintenance cost, and prolong the service life.
