Ruibian (Jiangsu) Electric Power Co., Ltd. is one of the leading manufacturers and suppliers of amorphous alloy core distribution transformer in China. With abundant experience, our factory offer high quality products made in China with competitive price. Welcome to contact us for pricelist.
Materials & Processes
Core: Amorphous alloy ribbon, with unit loss only 25% of silicon steel. Uses three-phase five-limb or three-dimensional wound core structures, with protective frames around the core.
Windings (oil-immersed): High-quality oxygen-free copper wire, vacuum-dried active part.
Windings (dry-type): Coils cast with Class H epoxy resin under vacuum.
Tank (oil-immersed): Corrugated tank or fully sealed construction, manufactured on automated production lines.
Energy efficiency levels: Available as S25 (NX1 Level 1), S21 (NX2 Level 2), S15 (NX3 Level 3), etc.
Key Advantages
Extremely low no-load losses: No-load loss reduced by 60%~70% compared to silicon-steel transformers of the same capacity.
Significant energy savings: Large-scale application yields substantial savings. For example, if all distribution transformers in Cangzhou region were replaced with new amorphous alloy types, annual electricity savings could reach about 200 million kWh.
High short-circuit withstand capability: Three-phase five-limb structure with frame protection gives a compact and rational design.
Stable operation: Vacuum-dried active part ensures low partial discharge.
Fully sealed design (oil-immersed): Effectively isolates air to slow oil aging – ideal for difficult maintenance areas.

FAQ
Q1: What standards do amorphous alloy core transformers comply with?
A: GB1094 "Power Transformers", GB/T6451 "Technical Parameters and Requirements for Three-Phase Oil-Immersed Power Transformers", GB/T 25446 "Technical Parameters and Requirements for Oil-Immersed Amorphous Alloy Distribution Transformers", and GB20052 "Energy Efficiency Grades and Values of Power Transformers".
Q2: What is the noise level of amorphous alloy core transformers?
A: Dry-type amorphous alloy transformers have noise levels 10~15 dB lower than the JB/T10088 standard. Oil-immersed types are even quieter due to oil damping.
Q3: Are amorphous alloy core transformers suitable for long-term no-load operation?
A: Very much so. The key advantage of amorphous alloy transformers is their extremely low no-load loss, so the energy-saving benefits are most prominent in scenarios with long no-load hours and low load factors.
