Amorphous Alloy Dry-Type Transformer

Amorphous Alloy Dry-Type Transformer

An amorphous alloy dry-type transformer is a high-efficiency, energy-saving power distribution device that utilizes an amorphous metal ribbon core and air as the cooling medium, eliminating the need for insulating oil.

Principle:
The metallic atoms in amorphous alloy materials possess a disordered, non-crystalline atomic structure, resulting in extremely low hysteresis loss compared to conventional silicon steel. When subjected to alternating voltage, the core undergoes rapid cyclic magnetization with drastically reduced excitation energy consumption. Windings rely on natural air convection or forced-air cooling (AN/AF) for heat dissipation. Furthermore, the core adopts a wound configuration, ensuring that the magnetic flux flows smoothly along the material's easy magnetization direction, which further minimizes no-load losses.

Core Advantages:

• Exceptional Energy Efficiency: No-load losses are approximately 70% to 75% lower than those of standard silicon steel dry-type transformers, offering massive energy-saving benefits during long periods of light-load operation.

• Superior Fire Safety: Non-combustible, risk-free from oil leaks, and possessing excellent explosion-proof properties.

• Reliable Operation & Low Maintenance: Features low operating noise, strong overload capacity, and an eco-friendly design that requires zero oil sampling, testing, or replacement, significantly simplifying routine maintenance.

• Limitations: The core exhibits relatively lower mechanical impact resistance, and initial equipment procurement costs are higher than traditional dry-type models.

Application Scenarios:
Primarily deployed in high-safety and strict fire-prevention environments, such as high-rise buildings, commercial complexes, hospitals, subways, data centers, schools, and underground utility tunnels. It is also widely utilized in indoor substations, industrial plant distribution, and renewable energy integration (such as solar and wind power step-up systems), perfectly aligning with modern grid decarbonization and energy-saving initiatives.
