Technical Data Sheet

76 MVA oil type power transformer specifications and data sheet

three phase power transformer

1.Three phase power transformer core is made of imported high-quality cold-rolled silicon steel sheets, which greatly reduces no-load loss and no-load current, and binds the core to ensure the tightness of the core and reduce noise.

2. The high and low voltage windings are made of oxygen-free copper. The low voltage windings of 500KVA and below adopt a double-layer cylindrical structure, and the high-voltage windings adopt a multi-layer cylindrical structure.

3. The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the power supply quality.

4. The transformer is a fully sealed structure, prolonging the service life, free of hanging cores and maintenance-free.

5. The measured noise value is lower than the standard.
