Product Overview:
The 10kV Amorphous Alloy Dry Type Transformer represents the pinnacle of modern energy-saving electrical distribution. By perfectly merging the ultra-low loss characteristics of amorphous alloy materials with the fire-proof, maintenance-free benefits of epoxy resin cast structures, STELLAR has engineered a transformer that delivers unparalleled operational efficiency and indoor safety.
Compared to traditional silicon steel transformers, this 3 phase amorphous alloy transformer dramatically slashes no-load losses by an astounding 60% to 70%. It is the ultimate eco-friendly choice for energy-intensive urban infrastructure, including high-rise commercial buildings, airports, subways, railway stations, and specialized power plants where strict fire safety and maximum energy conservation are mandatory.
Key Advantages:

The core of this transformer is crafted from advanced amorphous alloy ribbons rather than conventional cold-rolled silicon steel. Amorphous metal possesses a unique, randomized atomic structure that offers incredibly low magnetic reluctance. As a result, the transformer requires significantly less energy to magnetize the core. This technological leap reduces no-load losses (iron losses) by 60% to 70%, offering facility managers a rapid return on investment through substantial, continuous electricity savings over the equipment's lifespan.
While the amorphous core maximizes efficiency, the structural integrity is guaranteed by our premium epoxy resin encapsulation. The high and low voltage windings are cast under strict vacuum conditions, eliminating air bubbles and void spaces. This ensures an impeccably solid insulation matrix with high dielectric strength and virtually zero partial discharge, dramatically extending the operational life of the 10kv amorphous alloy dry type transformer.
Designed specifically for densely populated or high-risk environments, this dry type transformer contains zero flammable liquids. The epoxy resin is inherently flame-retardant and self-extinguishing, posing absolutely no fire or explosion hazard. It completely eliminates the need for expensive fire suppression vaults, allowing for safe, direct installation within commercial centers, subterranean subway stations, and high-rise service floors.
One historical challenge with amorphous cores is their mechanical fragility. STELLAR overcomes this through an innovative clamping framework and specialized winding support structures that isolate the core from physical stress. Combined with the rock-solid epoxy cast coils, the transformer exhibits outstanding mechanical rigidity, effortlessly withstanding the extreme electro-dynamic forces generated during sudden grid short-circuits.
The dense resin encapsulation acts as an impenetrable shield against humidity, dust, and corrosive airborne particles. This exceptional moisture resistance means the transformer can be safely energized without pre-drying, even after periods of shutdown in damp conditions. Without oil to test, filter, or replace, routine maintenance is virtually eliminated, saving operators significant time and labor costs.
An amorphous alloy transformer uses a core made from rapidly cooled metallic glass rather than traditional silicon steel. This unique atomic structure drastically reduces magnetic resistance, which cuts the transformer's no-load losses (idling energy waste) by 60% to 70%, leading to massive long-term energy savings.
Absolutely. Because it is a dry type transformer, it uses vacuum-cast epoxy resin instead of flammable oil. It is 100% flame-retardant, self-extinguishing, and non-explosive, making it the safest and most compliant choice for indoor installations like shopping malls, high-rises, and subways.
While amorphous metal itself is brittle, STELLAR uses an advanced, reinforced clamping frame that protects the core from mechanical stress. The epoxy-cast coils further reinforce the entire assembly, giving the transformer excellent mechanical rigidity and high resistance to sudden short-circuit forces.
As a leading China amorphous alloy transformer manufacturer, we supply these highly efficient units in a broad rated capacity range from 30 kVA up to 4000 kVA, stepping down standard 10kV grid voltages to 0.4kV for direct facility usage.
