S13-8000KVA oil-immersed power transformer is a self-developed product independently developed in the case of the original S11 oil-immersed transformer, according to the exploration and application of new materials and new processes and the combination of scientific and technological innovation and technology introduction, through the optimization and creative design of the core and coil structure, to achieve the effect of reducing no-load loss and noise. The average no-load loss of S13-8000KVA oil-immersed power transformer is reduced by 37%. The noise level of S13-8000KVA oil-immersed power transformer is reduced by 20% compared with the current national standard JB/T10088-2004, and the product characteristic level has reached the level.

Benefits:

The core of the S13-8000KVA oil-immersed power transformer is made of imported cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current, and binds the core to ensure the compactness of the core and reduce noise.

The high and low voltage winding resistance is wound with oxygen-free copper, the low-voltage winding resistance below 500kVA adopts a double-layer barrel structure, the 630kVA and above adopts a double helix or quadruple helix structure, and the high-voltage winding resistance adopts a two-layer barrel structure.

Dyn11 is used in the transformer connection group to reduce the impact of harmonics on the power grid and improve the quality of power supply.

The transformer is a sealed structure, which improves the service life, no hanging heart, and no maintenance.

The noise level of the evaluation is lower than the specification.

After normal transportation, the S13-8000KVA oil-immersed power transformer can be installed with relevant parts and components without hanging heart inspection, and can be put into operation after passing the inspection.

The S13-8000KVA oil-immersed power transformer developed and produced by the company has the advantages of low loss and low noise, which can achieve better energy-saving effect and reduce pollution. Compared with the general oil-immersed transformer, the S13-8000KVA oil-immersed power transformer cancels the oil storage tank, and the change of oil volume is automatically adjusted by the elasticity of the corrugated oil tank corrugated sheet, and the transformer is isolated from the air, preventing and reducing the deterioration of oil and insulation aging, improving the reliability of operation, and maintaining maintenance-free operation.
