3 Phase Oil Immersed Power Transformer

S11 belongs to the fully sealed distribution transformer with wound iron core, and it is a new generation of low noise and low loss transformer developed in recent years. 

S-11-M series fully sealed oil-immersed power transformer has the advantages of low loss, low noise and high efficiency, and can achieve good energy saving effect and reduce pollution.

Product Features:

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

2. The high and low voltage windings are made of oxygen-free copper, the low voltage windings 500KVA and below adopt a double-layer cylindrical structure, the 630KVA and above adopt a double-helix or quadruple-helix structure, and the high-voltage windings adopt a 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 the power supply.

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

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