Product overview
S11-M full-sealed oil-immersed power transformer developed by the Company has the advantages of low loss,

low noise and high efficiency and can achieve good energy-saving effect and reduce pollution. Compared with

common oil-immersed transformer, it is unnecessary for full-sealed transformer to be equipped with oil conservator

and change in oil volume is automatically adjusted and compensated by elasticity of corrugated sheet of corrugated

tank,and transformer is isolated from air to prevent and slow down oil degrading and insulation aging, enhance

operational reliability, with normal operation and no maintenance.

Product feature
1. The transformer core is stacked by imported high-quality cold-rolled silicon steel sheet, which reduces no-load current

greatly, and makes the core bound to ensure compactness of the core and reduce noise.
2. High-low voltage winding is wound with oxygen-free cooper, low-voltage winding of 500kVA and below adopts double

layer cylinder structure, that of 630kVA and above adopts double helix and four helix structure, and high-voltage winding

adopts mutilayer cylinder structure.
3. Transformer winding connection adopts Dyn11 to reduce influences of harmonic wave on the power grid and imporve

power supply quality.
4. The transformer is of full-sealed structure to prolong the shelf life and avoid suspended core use and maintenance.
5. The measured noise level is below the standard.
