Special Purpose Distribution Transformers
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.

Product Features：
1. Stainless steel edge bolts for a clean and durable appearance.
2. Vacuum oil filling to remove air bubbles and enhance short-circuit strength.
3. Fully sealed tank to isolate oil from air and slow oil aging; molded seals improve reliability.
4. Ultra-low losses:
SH(B)15-M: no-load loss and no-load current reduced by about 60% compared with S11.
SH(B)16-M: no-load loss and no-load current reduced by about 60%, load loss reduced by 10%.
5. Optimized winding structure:
1) Low voltage uses copper foil for uniform electric field.
2) LV inner frame uses molded paper tube.
3) HV windings use semi-overlap with non-woven glass tape.
4) Laminated wood pressing blocks improve mechanical strength.
