The S11/13-M series fully sealed oil-immersed power transformer developed and produced by our company has the advantages of low loss, low noise, and high efficiency, which can achieve good energy-saving effects and reduce pollution.Compared with ordinary oil-immersed transformers, fully sealed transformers have eliminated the oil storage cabinet. The change in oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank.The transformer is isolated from the air, which prevents and slows down the deterioration of oil and insulation aging, enhances operational reliability, and is maintenance-free for normal operation.

The transformer core is made of imported high-quality cold-rolled silicon steel sheets, which greatly reduces no-load loss and no-load current, and the core is tied to ensure compactness of the core and reduce noise.
The high and low-voltage windings are wound with oxygen-free copper. The low voltage winding 500kVA and below adopts a double-layer cylindrical structure, 630KVA and above adopts a foil coil, and the high voltage winding adopts a multi-layer cylindrical structure.
The transformer connection group adopts Dyn11 to reduce the impact of harmonics on the power grid and improve the power supply quality.
The transformer is a fully sealed structure, which prolongs the service life, does not require a hanging core, and does not require maintenance.
The measured noise value is lower than the standard.
