S20-1600KVA oil-immersed transformer is our company’s S13 transformer under the premise of S13 transformer, according to the integration of new materials, new technologies and scientific and technological innovation, according to the transformer core and electromagnetic coil structure optimization design, so as to reduce the transformer no-load loss, load loss and noise.

S20-1600KVA oil-immersed transformer Characteristics.

1. The core of the S20-1600KVA 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.

S20-1600KVA oil-immersed transformer defects

1. S20-1600KVA oil-immersed transformer oil is flammable, and may ignite and explode when encountering fire

2. Transformer oil is harmful to the body

3. The transformer oil needs to be maintained regularly

S20-1600KVA oil-immersed transformer oil is flammable, and may ignite and explode when encountering fire 2.

5. S20-1600KVA oil-immersed transformer has poor sealing and is suitable for aging, and the water and oil leakage in the operation site is serious, which endangers the safe operation of machinery and equipment, and at the same time damages the environment

6. S20-1600KVA oil-immersed transformer has low flame retardant grade, and is manufactured according to the A-class insulation layer design scheme
