Amorphous Alloy Dry-type Transformer

Amorphous alloy dry-type transformer meets the new energy efficiency standard GB 20052-2020, and has the advantages of energy saving and environmental protection, safety and reliability, low no-load loss, small no-load current, strong harmonic suppression ability, and high cost-effective operation.

Overview

Amorphous alloy materials

Amorphous alloy materials are synthesized by mixing iron, cobalt, carbon, silicon, boron and other elements in a certain proportion. Under high-temperature melting conditions, they are cooled by a high-speed rotary wheel at 10℃/S, so that the metal has no obvious lattice interface, thus forming an irregular amorphous structure.
