S11 type oil immersed transformer

2. The high and low voltage windings are made of oxygen free copper, and the low voltage windings of 500kVA and below adopt a double-layer cylindrical structure. 630kVA and above adopt double helix or four helix structure, and the high-voltage winding adopts multi-layer cylindrical structure.

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

4. The transformer is a fully sealed structure, which extends its service life, eliminates the need for hanging cores, and requires no maintenance.

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