S20-6300KVA oil-immersed transformer is a product independently developed by our company according to the exploration and application of new materials and new technologies and the combination of scientific and technological innovation and technological innovation, according to the creative design of improving the structure of iron core and electromagnetic coil, so as to reduce the effect of no-load loss and noise. The noise intensity is 20% lower than the current national standard JB/T10088-2004, and the product characteristic level has reached the leading level in China.

S20-6300KVA oil-immersed transformer characteristics

The improvement of S20-6300KVA oil-immersed transformer is manifested in two aspects: transformer core and transformer electromagnetic coil, S20 model specification transformer shell is fully enclosed, integrated into the outdoor sun and rain living environment, generally used in remote mountainous areas and new projects of rural network renovation projects.

The core of the S20-6300KVA oil-immersed transformer is made of ferrite core with better quality, the core is neat, the three-proof paint film does not fall off, the core on the side can not be warped up and will be wavy, the surface of the core is free of oil and sundries, there is no short circuit fault between the pieces, the lap of the steel bar, the gap at the joint meets the regulations, and the no-load loss of the core of the S20 transformer is better than that of the core of the S13 transformer.

Advantages of S20-6300KVA oil-immersed transformer

(1) High voltage: The primary voltage of the experimental transformer is 220V or 380V, but the secondary voltage of each experimental transformer often reaches thousands of volts to hundreds of thousands of volts. Experimental transformers with secondary voltages exceeding 750kV generally adopt several cascade structures.

(2) Small current: The rated voltage of the experimental transformer is actually the capacitance current of the tested material, so it is generally lower than 1A. However, the secondary current can reach several amperes for cable and various motor tests, external insulation and pollution experiments, distribution line corona discharge experiments and other experimental transformers.

(3) Short working time: due to the short voltage resistance time of the tested new product, the experimental transformer is generally 0.5h or 1h short-time working system except for the insulation and pollution test, the corona discharge test of the distribution line, and the cable test.
