Product Description

S11 Series 3-phase 33KV Oil-immersed Power Transformer

3 Phase 33KV Electrical Power Transformer Oil Immersed Type With Full Sealed Structure 0

Product features 
1, Transformer core is made of stacked imported high-quality cold-rolled silicon steel sheets. This has
     reduced the no-load loss and current greatly and conduct bind for iron core, is able to ensure the
     compactness of iron core and reduce noises.
2, High and low voltage winding is made of oxygen-free copper. Low-voltage winding 500kVA and below
   adopts double-cylinder structure; 630kVA and above adopt double-helix or four-spiral structure;
   high-voltage winding adopts multi-layer cylindrical stmcture.
3, Transformer connection group adopts Dyn11 to reduce effect of harmonics on network and improve
    power-supply quality.
4, Transformer is full sealed structure which can prolong service life, and avoid hanging core and
5, Measured noise value is lower than standard. This series transformers need not to do hanging center
