Taili S(B)H Amorphous Alloy Oil immersed transformer uses material of amorphous alloy and adapts ultra-rapid cooling technology to produce the core, where liquid metal is cooled at 10⁶ °C/s to form 0.02–0.04 mm thin strips. This material has excellent magnetic performance, no crystalline defects, and requires very low magnetization power. A typical amorphous alloy contains 80% iron with boron and silicon as additional elements.
