Foshan – September 30, 2026 -- Transmart Industrial Limited is expanding its push into North America, betting that ultra-thin nanocrystalline ribbon technology will capture demand from AI data centers and power grid upgrades as U.S. electricity consumption enters its strongest four-year growth streak since 2000.
Transmart manufactures nanocrystalline ribbon at 12 to 14 micrometers, a thickness achieved by only a small number of manufacturers worldwide
The thinner ribbon reduces eddy-current losses at high switching frequencies, letting engineers design transformers, inductors and filters that run cooler while shrinking in size and weight for a given power rating. Transmart's self-developed, patented production lines cover precision slitting, automatic winding, vacuum annealing and multi-wire cutting, giving the company direct control over ribbon dimensions, magnetic properties and core geometry.
Nanocrystalline cut cores hit core losses as low as 0.4 W/kg under 20 kHz, 50 mT test conditions
The company's 3000-permeability low-permeability nanocrystalline ribbon is engineered for high-frequency transformer applications requiring stable performance across a wide frequency range. Its amorphous core portfolio covers toroidal, C-core, E-core, block and amorphous stator geometries for lower-frequency, high-efficiency applications, while a full-range grain-oriented silicon steel platform spans 0.05 mm to 0.35 mm thicknesses across eight standard increments.
Transmart runs two dedicated China-based facilities certified to ISO 9001, ISO 14001, ISO 45001 and IATF 16949
One plant focuses on silicon steel cores, current sensor cores and instrument transformer cores; the other produces nanocrystalline cores, amorphous cores and common mode chokes. The company, in business more than 25 years, serves customers in over 50 countries, with a base historically concentrated in Europe.
U.S. electricity demand is projected to rise 3% in 2027 after 1% growth in 2026, per EIA data
The U.S. Energy Information Administration's January 2026 Short-Term Energy Outlook marks this as the first four-consecutive-year demand increase since 2007, driven largely by large-scale computing facilities and AI workloads. Transmart is citing this trend as the basis for growing engagement with customers, partners and engineering teams across North America, targeting power grid distribution, AI data center power conversion, renewable energy inverters, EV charging infrastructure and EMI/EMC filtering applications.
"As power systems move toward higher frequencies and greater density, the performance of the core material becomes one of the defining factors in system design," said Richard Long, Director of Transmart. He added that North America is a market where this shift is happening quickly.

The company positions its ultra-thin ribbon processing and high-frequency core design as a technology foundation for SST, though the architecture remains at an early R&D stage with limited commercial deployment.
