On the basis of the first generation three-phase five column amorphous alloy dry-type transformer, the SC (B) H15 series has improved the structure of the amorphous iron core and launched an innovative generation of amorphous alloy dry-type transformers with energy-saving, safety, and environmental protection concepts. The product is safe, reliable, and environmentally friendly, significantly reducing no-load losses and load losses. The no-load losses are reduced by three-quarters compared to ordinary dry-type transformers, making it an advanced dry-type transformer in the world today. Amorphous dry transformation products have flame retardant, explosion-proof, non polluting, and high fire rating; High mechanical strength, strong ability to withstand short circuits, safe and reliable operation; Low noise, small size, easy installation, and maintenance free; Small partial discharge, high insulation level, and long product service life; Excellent "three defenses" capability and strong overload capacity; The primary and secondary sides can choose any connection method and other features.
