3. Structural and technological features

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

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

• Wound core design with fewer joints, uniform magnetic circuit, and low excitation current.

• Integral epoxy encapsulation provides moisture resistance, corrosion protection, and vibration isolation.

• Extremely low no-load losses, virtually no heat generation.

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

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

• High-voltage multi-layer cylindrical winding: balanced ampere-turns, excellent short-circuit withstand capability.

• Vacuum epoxy casting with fiberglass reinforcement: bubble-free, crack-free, high strength.

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

3) Temperature control and intelligent monitoring

• PT100 platinum resistors embedded in windings ensure precise temperature measurement.

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

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

4) Enclosure and housing

• Fully sealed design: moisture-proof, dust-proof, salt-fog resistant, pollution resistant.

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

• Electrostatic plastic spraying casing: anti-corrosion, aesthetic, and durable.

• For outdoor installation, a rain shelter is provided.

4. Main Product Advantages

1) Ultra-economical

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

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

2) Safe and fire-resistant

• Oil-free, leak-free, no risk of fire or explosion.

• Class F1 fire resistance, smokeless, non-toxic, non-flammable.

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

3) Ultra-low noise level

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

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

4) High short-circuit resistance

• Cast-in-place windings with high mechanical strength.

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

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

5) High environmental adaptability

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

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

• Can be put into operation immediately after shutdown without pre-drying.

6) Maintenance-free and long service life.

• No need for oil use, oil replacement, filtration, or testing.

• Planned technical maintenance includes only dust cleaning and connection inspection.

5. Application Scenarios

• Upgrading urban and rural power grids (State Grid Corporation of China, China Southern Power Grid).

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

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