S13-Type Oil-immersed Power Transformer
The S13 model is a self-developed product developed by our company based on the original S11 distribution transformer, through the integration of research and application of new materials and manufacturing processes with independent innovation and technology adoption. By optimizing and innovating the design of the iron core and coil structure, it achieves the objectives of reducing no-load losses and noise levels.
The noise level has decreased by an average of 20% compared to the current national standard JB/T10088-2004, and the product performance meets advanced domestic standards.
Product Overview
The S11、S13、S20、S22-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 effect and reduce pollution. Fully sealed transformer and ordinary oil-immersed transformer, compared with the elimination of the oil storage cabinet, oil volume changes by the corrugated oil tank corrugated sheet of the elasticity of the automatic adjustment to compensate for the transformer isolated from the air to prevent and slow down the deterioration of the oil and the aging of the insulation, enhance the reliability of the operation, the normal operation of maintenance-free.
Product Features
◆ Transformer core is made of high quality cold rolled silicon steel sheet stacked together, greatly reducing no-load loss and no-load current, and the core is tied to ensure that the core of the tightness and reduce noise;
◆ High-voltage and low-voltage windings are wound with oxygen-free copper, and the low-voltage winding is of layer-cylinder structure for 315KVA and below. 400KVA and above low-voltage is of foil-winding structure, and the high-voltage winding is of multi-layer-cylinder structure;
◆ Transformer connecting group adopts Dyn11 to reduce the impact of harmonics on the power grid and improve the quality of power supply;
◆ Transformer is fully sealed structure, prolonging service life, free of core lifting, free of maintenance;
◆ The measured noise value is lower than the standard. After normal transportation, this series of transformers can be put into operation without core lifting and checking, installing relevant parts and components, carrying out acceptance project test, and passing the test.
Conditions Of Use
◆ Maximum ambient temperature: +40°C;
◆ Minimum ambient temperature: -25°C;
◆ Altitude: <1000m;
◆ Maximum monthly average relative humidity: 90% (20℃ );
◆ Installation location: installed in places without fire, explosion danger, serious filth, chemical corrosion and severe vibration, indoor or outdoor.
