3. Structural and technological features

1) Amorphous alloy as a core (the main energy-saving component)

• Ultra-thin amorphous alloy strip with high magnetic permeability and extremely low loss.

• Core design with winding, fewer connections, uniform magnetic circuit and low excitation current.

• A solid epoxy seal provides moisture resistance, corrosion protection and vibration isolation.

• Extremely low idle losses, virtually no heat generation.

2) Winding design (high reliability and short circuit resistance)

• Low voltage copper foil winding: uniform current density, low eddy current, good heat dissipation.

• High voltage multilayer cylindrical winding: balanced number of ampere turns, excellent short circuit resistance.

• Vacuum epoxy casting with fiberglass reinforcement: no bubbles, no cracks, high strength.

• Class H thermal insulation: heat-resistant, moisture-resistant, anti-aging, impact-resistant.

3) Temperature control and intelligent monitoring

• PT100 platinum resistors built into the windings provide accurate temperature measurement.

• Intelligent temperature controller: overheat alarm, protection triggering, automatic fan control.

• Standard RS485/Modbus interface, connection to power monitoring systems and autonomous control systems.

4) Body and casing

• Fully sealed design: waterproof, dustproof, salt fog resistant, stain resistant.

• High-strength steel clamping structure: seismic and impact resistance during transportation.

• Housing for electrostatic plastic spraying: anti-corrosion, aesthetically pleasing and durable.

• For outdoor installation, a rain cover is provided.

4. Main advantages of the product

1) Super economical

• Amorphous alloy core with industry-leading low no-load losses.

• Long-term operating costs for electricity are reduced by more than 50% compared to traditional transformers.

2) Safe and fireproof

• No oil, no leaks, no risk of fire or explosion.

• Fire resistance class F1, smokeless, non-toxic, non-flammable.

• Can be installed directly in basements, distribution boards, high-rise buildings, shopping centers, hospitals.

• There is no need for oil pits, fire walls or fire suppression systems, which significantly reduces construction costs.

3) Ultra-low noise level

• Wound core combined with anti-vibration design, noise level ≤45dB(A).

• Quiet operation, suitable for residential areas, schools and hospitals.

4) High short circuit resistance

• Solid cast windings with high mechanical strength.

• Excellent resistance to lightning impulses, short circuits and overloads.

• Significantly lower failure rate compared to oil-cooled and conventional dry-type transformers.

5) High adaptability to the environment

• Moisture-proof, dust-proof, anti-condensation, salt fog resistant, corrosion-resistant.

• Suitable for coastal, chemical, mining, wet and dusty environments.

• Can be put into operation immediately after stopping, without preliminary drying.

6) It does not require maintenance and has a long service life.

• No oil use, oil changes, filtration or testing required.

• Scheduled maintenance only includes dust cleaning and checking connections.

5. Application scenarios

• Modernization of urban and rural power grids (State Grid Company, South Grid Company of China).

• Residential areas, schools, hospitals, office buildings with high requirements for noise and fire safety.

• Shopping malls, subways, airports, train stations, indoor distribution centers.

• Factories, mines, chemical and metallurgical industries (wet, dusty, explosive environments).

• Photovoltaic systems, wind energy, energy storage systems (significant energy savings during long-term no-load/low-load operation).

• Basements, high-rise buildings and crowded areas (no fire hazard, safe and secure).
