S22 type is our company in the original S20 type distribution transformer on the basis of the research and application of new materials, new technology and through the combination of independent innovation and technology introduction, through the optimization of the core and coil structure of the innovative design, to achieve the purpose of reducing no-load loss and noise. Self-developed products.
◆S22 type ultra-low loss fully sealed oil-immersed power transformer is the latest energy-saving transformer designed and produced by our company.
◆S22 series products produced by our company are all made of Shanghai Baosteel 0.18-0.20mm Q-series high permeability curvature silicon steel sheet, high and low voltage windings are all made of all copper foils and copper conductors, and fully sealed corrugated sheet oil tank structure is adopted, which has remarkable economic benefits in network operation.
◆The internal positioning structure of the body is designed to ensure that there is no displacement during transportation. At the same time, all fasteners are fitted with lock nuts to ensure that the fasteners do not loosen during long-term operation and to meet the requirement of not lifting the core.
◆Fully sealed structure design makes the transformer body isolated from air, preventing and slowing down the deterioration of transformer oil and moisture, enhancing the operation reliability.
◆Safety design, installed with pressure relief valve, signal thermometer, gas relay to ensure the safe operation of the transformer.
◆The surface of oil tank is painted with three-proof paint (rain-proof, moisture-proof, salt spray-proof) after oil removal, rust removal and phosphating treatment, which can meet the requirements of metallurgy, petrochemical system and other special environments in humid and dirty areas. The noise level is reduced by 25% on average compared with the current national standard JB/T10088-2004, and the performance level of the product has reached the domestic advanced level.
