Description:

Our company provide 220kV and below oil-immersed power transformer ,with capacity of 360 MVA and below. The 220KV transformer is based upon world-wide advanced technology and also incorporates the experiences of internationally leading transformer companies as well as our own long-term experiences.Our transformer conform entirely with latest national standard GB1094.1~2-1996, GB1094.3-2003, GB1094.5-2003 and international standard IEC-76. Outstanding features as follows:

1. Low loss, and significantly energy-saving. The average no-load loss is 35% lower than prescribed by National Standard GB/T 6451-2008.

2. The core laminations are made up from high-quality cold-rolled grain-oriented silicon steel sheets with chamfered joints and without punched holes, and are stacked without the upper yoke sheets in place, so that they are effectively improved no-load upper together with lower frame.

3. Zigzag directed flow of oil are provided within the windings, so that all parts of the windings can be cooled more evenly.

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.
