Features:
1. Low loss, and significantly energy-saving.
2. The core laminations are made up from high-quality cold-rolled
grain-oriented silicon steel sheets
3. Zigzag directed flow of oil are provided within the windings
4. The regulating winding is a separate winding which apart from
the high voltage main winding
5. The windings of one phase are assembled into an integral phase
block before placing into the core.
6. Core frames in the form of a flat plate are used for clamping
the core.
7.Transformer tanks are fabricated with steel plates wide enough so
that there are no weld joints on each surface.
8.Diaphragm membrane is provided within the conservator, preventing
direct contact of oil with air, protecting the oil from aging
