Technical features

• 1. The core is made of high-permeability, low-loss cold-rolled oriented silicon steel strip, and adopts a unique lamination structure to minimize the distortion of magnetic flux density, thereby greatly reducing no-load loss and no-load current. Since the core joint air gap of this type of transformer is small and the joints of each layer are staggered, the no-load loss is smaller, the no-load current is lower, and the noise is reduced by 5-10dB.
• 2. The low-voltage winding can be wrapped in foil, which has a compact structure and reduces the radial force during short circuit, greatly enhancing the ability to resist sudden short circuit.
• 3. The box adopts a fully sealed structure of corrugated oil tank to prevent air and moisture from contacting the transformer oil, reduce the degree of oil aging, and extend the service life of the transformer; the volume change of transformer oil due to thermal expansion and contraction is adjusted through the elastic deformation of the corrugated sheet.
