Amorphous Alloy Transformers Overview
Amorphous alloy transformers are the lowest-loss choice for lightly loaded distribution networks. The core uses an amorphous metal ribbon (Fe-Si-B) instead of grain-oriented silicon steel - its disordered atomic structure nearly eliminates magnetic hysteresis loss, cutting no-load (iron) losses by 60-70% compared with a conventional core. QDTB builds them from 30 kVA to 1,600 kVA to Class 1 efficiency per GB 20052. Because no-load loss flows 24/7 regardless of how much power is drawn, the amorphous core pays for itself fastest in rural feeders, PV plants that idle overnight, and residential networks that run at a low average load.
Available Series
SBH15-M Series
The SBH15-M series combines oil-immersion technology with amorphous alloy core material, achieving ultra-low no-load losses for energy-efficient power distribution.
SCBH15 Series
The SC(B)H15 series combines cast resin dry-type technology with amorphous alloy core, delivering ultra-low losses with fire-safe, maintenance-free operation.
SH16 Amorphous Transformers Series
SH16 series amorphous alloy distribution transformers use amorphous metal cores for ultra-low no-load loss, exceeding SH15/SBH15 energy-saving grades. Rated 30–1600 kVA, 6/10/35 kV primary, oil-immersed, for energy-efficiency programs where minimum no-load loss is the priority.

Application Scenarios
Rural distribution
Long feeders with low average load; no-load loss is the biggest waste, so amorphous pays back quickly.
Solar PV plants
The transformer stays energized overnight while the array produces nothing; amorphous minimizes that standby loss.
Residential networks
Load peaks in the evening and idles overnight; the 24/7 no-load saving adds up fast.
Wind farms
Variable, fluctuating loading; the low-loss core keeps efficiency high across the whole operating range.
Green buildings / LEED
Energy-efficiency certification credits favor lowest-loss distribution equipment.
Smart grid
Low-loss operation complements demand-response and renewable integration programs.
Technical Advantages
Amorphous metal core
Fe-Si-B ribbon with a disordered atomic structure; hysteresis loss is a fraction of grain-oriented silicon steel.
60-70% lower no-load loss
The dominant loss source on lightly loaded or continuously energized networks.
Class 1 efficiency (GB 20052)
Highest energy-efficiency grade; supports LEED and green-building credits.
Lower total cost of ownership
Modest price premium recovered in 3-5 years on low-load networks, then pure savings for 20+ years.
