Dry-type Power Transformer

The SG12 series dry-type transformer refers to transformers whose core and windings are not immersed in insulating oil. The SG12 dry-type power transformer is a three-phase, non-encapsulated (open type), vacuum impregnated dry-type power transformer. Both the high and low voltage windings use NOMEX(R) paper insulation recognized by UL in the USA. They are vacuum pressure impregnated with H-class solvent-free insulating varnish and cured at high temperatures. Produced using advanced VPI (Vacuum Pressure Impregnation) technology, it differs significantly from traditional F-class epoxy resin cast dry-type power transformers not only in the insulating materials used but also in electromagnetic, mechanical, and temperature rise calculations, structural layout, and manufacturing processes. Its insulation heat resistance rating, partial discharge measurement, load overload capacity, and adaptability to external environments have all been significantly improved and enhanced.
