Our High Efficiency Amorphous Dry Type Transformer works very well when you need a way to distribute power that blends cutting-edge technology with tried-and-true dependability. With an amorphous metal core, this advanced transformer cuts core losses by 70–80% compared to regular units, getting 98.5–99.2% efficiency rates. Every unit meets ISO9001 quality standards and is backed by 18 patents. It is made with more than 120 sets of advanced equipment, such as CNC automatic winding machines and microcomputer-controlled gradient curing ovens. Our technical team of 15 senior engineers and 30+ intermediate techs will make sure you get a transformer that uses less energy, doesn't need oil, and doesn't need any upkeep for more than 30 years.

You might be curious about what makes amorphous transformers different from other types. The answer lies in the subject itself.
We use amorphous ribbon in our transformers. It is made from metals of Fe, Ni, Co, B, and C. This makes an atomic shape that is not solid. As a result? At the rated flux density, core losses can be as low as 0.15 to 0.25 watts per kilogram.
When you look at standard silicon steel cores, they only give off 1.0 to 1.3 W/kg. Your energy bills will change right away to show the difference.
The irregular string is only 20 to 25 micrometres thick. This very thin form makes magnetic leakage much better. It cuts eddy current losses by a huge amount.

Every kilowatt you save means lower costs for running your business. Our transformers' magnetic features stay stable over a wide range of temperatures. Whether you're at full load or only partially loaded, the efficiency stays the same.
Temperature rises that are 20 to 30°C lower than normal levels will be good for your building. This means that less cooling is needed. Not as much air cooling. Spend less on HVAC.
When you build without using oil, there are no fire risks at all. You won't need tools to keep oil inside or keep an eye on leaks. There is no danger to the earth from oil spills.
The cast resin shielding method keeps fires from starting and puts them out on its own. Even in the worst situations, your building is safe.
This makes them perfect for places that are likely to catch fire, like high-rises, subways, airports, stops, and more.
You should not constantly fix transformers. There are more important things to do. Our plan will last for more than 30 years without needing much upkeep.
No oil changes. No worries about moisture. The cast plastic construction naturally stands up to the elements.
Time is saved by your team. Your budget stays the same.

Your sensitive equipment demands clean, stable power. Our transformers deliver exceptional power quality with noise levels below 45 dB. The high efficiency reduces cooling loads in your temperature-controlled environment.
Solar farms and wind power stations face harsh conditions. Our transformers handle variable loads and extreme temperatures from -40°C to +50°C. The weatherproof construction ensures reliable operation year-round.
Continuous process operations require 99.9% reliability. Our transformers provide robust short-circuit withstand capability exceeding 25 times rated current. You get uninterrupted power for critical production lines.
We've successfully delivered solutions for XCMG Group factory power supply upgrades, GCL Photovoltaic Industrial Park, and numerous electronic industrial parks. Each project was completed ahead of schedule while maintaining strict quality standards.
From the Xinhuai Central Complex to Zhongjun Huijingcheng, our transformers power major commercial developments. They fit into confined spaces with footprints 15-25% smaller than conventional units.
Critical infrastructure demands absolute reliability. We've supplied Xuzhou Rail Transit Network Control Center and Xuzhou High-speed Railway East Station with dual-circuit power supply designs featuring High Efficiency Amorphous Dry Type Transformer. These installations ensure uninterrupted service for thousands of daily commuters.
You deserve confidence in every transformer you purchase. That's why we implement strict quality management at every stage.
Our production process includes:
Every step follows our "zero defects" philosophy integrated into ISO9001 quality management standards.

Before any transformer leaves our facility, it undergoes:
Core Loss Verification: Per IEC 60404-2 standards, confirming efficiency claims through precise no-load loss measurements
Partial Discharge Testing: According to IEC 60270, ensuring insulation integrity below 10 pC at 1.5 times rated voltage
Temperature Rise Testing: Per IEC 60076-11, validating thermal performance under rated load conditions
Short-Circuit Withstand Testing: Demonstrating mechanical strength under fault conditions
Routine Inspections: Including winding resistance measurement, insulation resistance exceeding 1000 MΩ, and voltage ratio accuracy within ±0.5%
Our professional quality inspection laboratory provides third-party validation. You receive independent certification of efficiency ratings and safety compliance.

Most buildings get their money back in three to five years just by saving energy. The exact time varies on how much power you use and how often you use it. Our transformers cut no-load losses by 70–80%, which saves you money all the time. Demand charges are also lower during busy times when efficiency is higher.
Of course. The IP20 to IP54 grades come from the cast resin structure. From -40°C to +40°C and up to 95% humidity, they work consistently. The design is resistant to water and cracks, and it can handle changes in temperature. We've successfully put units in workshops, outdoor substations, and places near the coast that are prone to corrosion.
Amorphous cores don't lose their magnetic properties over time like silicon steel cores do. They keep their properties fixed for more than 30 years. Thermal stress doesn't break down the non-crystalline structure. Ratings of performance will stay the same from year to year. If performance doesn't go down, energy saves last longer.
Our design can handle short-circuit currents that are more than 25 times the maximum current. The cast plastic design keeps the windings in place when there is a fault. Before delivery, this ability is confirmed by thorough short-circuit testing that meets IEC standards. Your organization of system safety works as it should.

The change in performance is big. When compared to regular silicon steel, amorphous cores cut no-load losses by 70–80%. This will save a lot of energy, especially for generators that are used all the time. The effect on the environment is also big: lower losses mean less CO2 emissions over the life of the generator. Amorphous technology has clear benefits for buildings that want to be more environmentally friendly and cut down on operating costs.
