The first batch of commercially produced amorphous alloy transformers made in Shanghai in 1998 were quietly displayed in the factory.
Only its witnesses know that the accelerated heartbeat, the slight pain from trembling palms, and the burning sensation in the eyes are all proof that China has ended its "dependence on imported materials and technology" for amorphous alloy transformers.
At that time, 16 years had already passed since the United States launched the first commercial bullet.
In 1982, a 10kVA amorphous alloy transformer was put into actual grid operation. By 1986, GE achieved the mass production of amorphous alloy transformers and officially entered the commercial market.
Just over 20 years later, China's share of the global amorphous transformer market is set to exceed 45%.
Technically, the thickness of iron-based amorphous alloy strips has surpassed 18 micrometers. After the expiration of Hitachi Metals' patents, China's annual patent applications increased by 34%, with transformer energy-saving efficiency further improving by 30%-40%.
From following to leading, this marks a transformative turning point, with amorphous alloy transformers serving as the unwavering witness from beginning to end.
From the first practical transformer in 1885 to the first amorphous alloy transformer prototype in 1979, traditional silicon steel sheets spent nearly a century establishing an absolute rule in the power industry
Silicon steel sheets are the core, thickness ensures reliability, and losses are a necessary cost
This set of rules is firmly held by the giants of traditional silicon steel material technology, and even to this day, it still boasts a large number of steadfast and reliable adherents.
Monopoly implies layer-by-layer price hikes. Until the early 21st century, high-end silicon steel sheets in China still relied on imports, with the core material cost of a 10kV silicon steel transformer accounting for over 60%.
The giants resting on their laurels, amassing wealth but updating at an extremely slow pace, have also given our country an opportunity to catch up and surpass them
From 2016 to 2024, the production of silicon steel increased from 8.65 million tons to 18 million tons, with an average annual growth rate of 8.1%;
By 2024, the production share of high-permeability oriented silicon steel (HiB) will reach as high as 68%;
The global amorphous transformer market accounts for over 45%.
The traditional transformers, seemingly reaping the benefits of monopoly, were easily revolutionized by new materials and technologies due to their hidden massive energy waste.
According to relevant data, the total no-load loss of hundreds of millions of traditional transformers nationwide exceeds 70 billion kilowatt-hours annually, equivalent to the annual power generation of three Three Gorges power stations.
As energy conservation and carbon reduction become global consensus, and with the advent of AI driving massive power demands, the high losses of traditional transformers—when compared to the energy efficiency of new technologies and materials—ultimately serve as the first hammer to shatter the old rules.
Every breakthrough carries the determination to stand firm after breaking through, and amorphous alloy transformers are the ones who broke through this situation.
Compared to the huge resistance of magnetic domain movement in the regular crystal structure of silicon steel sheets, the disordered amorphous structure of amorphous alloys is much more friendly to the movement of magnetic domains, with hysteresis loss only 1/4 of that of silicon steel sheets.
This material characteristic made Newtranstech SCBH19 born in Rome, which is a significant blow to the evolution of oriented silicon steel transformers from non oriented silicon steel.
Moreover, SCBH19 adopts independently developed high-performance amorphous alloy strip, with a yield rate of up to 90% and a cost reduction of 25% compared to early imported materials.
In terms of structural design, the dry oil-free architecture combined with optimized iron core structure not only has the same overload capacity as oil transformers, but also avoids oil leakage and pollution risks, greatly improving scene adaptability.
If a single technological breakthrough is not enough to shake old rules, then the full dimensional compatibility of SCBH19 is enough to crush them.
Since 2021, the proportion of SCBH19 in procurement has skyrocketed from 15% to 75%, and its proportion in supporting transformers for new energy power plants has exceeded 80%.
Most importantly, from dry-type transformers and oil immersed transformers to three-dimensional wound iron core transformers and photovoltaic step-up transformers Amorphous alloys have always participated in and changed the pattern of transformers in the power industry as a disruptor, and have established themselves to the world through innovation time and time again:
Energy saving is no longer just icing on the cake!
Reliability, not just relying on giants!
China can also be the answer to the world!
Newtranstech,always contributing their own strength！
