Product features:
1.Transformer core with imported high quality cold-rolled silicon steel sheet laminated product and, greatly reduce the no-load loss and no-load current, and the core of colligation and ensure the core compaction, reduce the noise.
2.high and low voltage winding with copper winding, the low voltage winding 500KVA and below the double cylinder type structure above 630KVA double helix or four helix structure, high voltage winding multi-layer cylindrical structure.
3.transformer connection group by Dyn11, to reduce the impact of harmonics on the grid, improve power quality.
4.transformer is sealed and prolong the service life, free hanging, maintenance free.
5.The measured noise value is lower than the standard.
This series of transformer through normal transportation, without lifting core, can be installed on the parts of the project acceptance test, after passing can be put into operation.
