S20-800KVA oil-immersed transformer has a series of advantages of high working efficiency, low consumption and low noise, which is suitable for the driving force and lighting power consumption of rural power grids and remote mountainous areas, and is an environmentally friendly and energy-saving power supply mode suitable for the transformation of power grids in large cities and high-voltage users of each family. The S20-800KVA oil-immersed transformer can be assembled directly on the Internet and can also be suspended on a utility pole. It has a very significant power-saving and energy-saving effect.

S20-800KVA oil-immersed transformer characteristics

1. The S20-800KVA oil-immersed transformer is made of 70 ferrite core, the performance and quality of the iron core, the electromagnetic coil is made of red copper special cable, the welder-grade insulated laminated wood, the low-voltage winding is made of cylinder or spiral structure, the ampere turn is evenly balanced, the short-circuit resistance is strong, the deformation is not deformed, it is not easy to crack, and the impact toughness is high.

2. The S20-800KVA oil-immersed transformer is equipped with a corrugated oil tank, and a pressure release valve, data signal temperature gauge, gas relay, etc. are set up according to the requirements to ensure the safe operation of the transformer.

3. The oil tank and clamps are solved by anti-rust treatment, pickling passivation, phosphating treatment and several times baking paint, and the unique anti-corrosion paint is adopted, which does not fall off and can meet the unique use needs of the metallurgical industry, petrochemical system and wet, cold and dirty areas.

4. S20-800KVA oil-immersed transformer adopts sealed structure, cover edge design, transformer oil and air barrier, moisture-proof and waterproof, slows down the aging of transformer oil, and increases the service life of transformer.

S20-800KVA oil-immersed transformer is a secondary energy efficiency oil-immersed transformer, the consumption is significantly lower than that of S13 transformer, S20 transformer uses the best design scheme, S20 transformer is high, so the price of secondary energy efficiency transformer is also very high.

Advantages of S20-800KVA oil-immersed transformer.

1. The core of the S20-800KVA oil-immersed 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 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 lifting core, carry out new project experiments, and can be put into use after reaching the standard.
