In daily life, S20-12500KVA oil-immersed transformer is the key machinery and equipment in power construction, in the requirements of the new industrial chain, the development trend of environmentally friendly, low-noise, intelligent power distribution equipment transformer products have become an inevitable trend, the S20-12500KVA oil-immersed transformer designed and manufactured by our company adopts a sealed corrugated oil tank structure, which has the characteristics of durability, easy maintenance and stable performance, and the economic benefits are obvious. The S20-12500KVA oil-immersed transformer is rugged and durable.

Brand advantage

The S20-12500KVA oil-immersed transformer is rugged and durable. The sealed transformer cover and the edge of the box are connected by anchor bolts or welded to prevent oil and air contact, and the insulation resistance is not easy to return moisture, which greatly reduces the insulation aging rate and improves the service life. The design scheme has a simple structure and low operating noise. Due to the use of new materials and new technologies, noise is reduced, there is no oil conservator, and the relative height is lower than that of the same industry. There is no need to change the oil during the normal service life, which improves the safety and stability of network operation.

Benefits:

1. The core of the transformer is made of advanced cold-rolled ferrite cores, which greatly reduces the no-load loss and no-load current, and bundles the core, improves the compactness of the core, and reduces noise.

2. The wire coil inductance for high and low voltage winding, and the two-layer barrel structure is selected for low voltage winding below 500kVA. 630kVA or above is a double helix structure or a quadruple helix structure, and a double-layer drum structure is used for the high-voltage winding.

3. Dyn11 is selected for the transformer connection group to reduce the harm of harmonic current to the power grid system and improve the reliability of power supply.

4. The transformer is a fully enclosed structure, which prolongs its service life, and is free of hanging core and maintenance.

5. The evaluation noise value is less than the specification. After the normal transportation of this series of transformers, they can assemble relevant parts and components without the inspection of the hanging core, carry out new project experiments, and can be put into use after reaching the standard.

S20-12500KVA oil-immersed transformer is an upgraded version of S9 power engineering transformer, which continues the advantages of low consumption, low noise and high quality, which can obtain good energy-saving effects and reduce environmental pollution. Compared with the general oil-immersed transformer, the fully enclosed transformer cancels the oil storage cabinet, and the change of oil weight is adjusted by the corrugated toughness of the corrugated oil tank, and the transformer and the air barrier avoids and alleviates the oil deterioration and insulation aging, improves the reliability of operation, and the normal operation is durable.
