Product Overview
The three-phase amorphous alloy dry-type distribution transformer represents the next generation of green, energy-saving transformer technology. It combines the ultra-low no-load loss characteristics of amorphous alloy core materials with the safety and environmental benefits of dry-type construction. The core is made of advanced amorphous alloy – a "non-crystalline metal" with randomly arranged atomic structure, produced by rapid quenching solidification technology, which enables significantly easier magnetization and demagnetization compared to conventional silicon steel.
This transformer features epoxy resin vacuum-cast windings with a fully encapsulated design, offering excellent electrical insulation, mechanical strength, and moisture resistance. It delivers exceptional energy efficiency, fire safety, and maintenance-free operation, making it the ideal choice for indoor distribution applications where both energy conservation and safety are top priorities – including commercial buildings, hospitals, data centers, airports, subways, and high-rise residential complexes.

Key Features
1. Ultra-Low No-Load Loss & Superior Energy Efficiency
• No-load loss reduced by 70-80% compared to conventional silicon steel dry-type transformers
• No-load current approximately 50% lower than silicon steel core transformers
• Particularly suitable for applications with low average load rates and long standby periods – delivering maximum energy savings and rapid return on investment
2. Fire Safety & Environmental Protection
• No insulating oil used – completely eliminates oil leakage, fire, and explosion risks
• Self-extinguishing, flame-retardant materials meet international fire safety standards
• Environmentally friendly, fully recyclable materials with zero pollution to the surrounding environment
• Suitable for installation in densely populated areas and fire-sensitive environments
3. Excellent Short-Circuit Withstand Capability
• Epoxy resin vacuum-cast windings provide superior mechanical strength and coil rigidity
• Glass-fiber reinforced structure enhances impact resistance and prevents winding deformation
• Robust mechanical design withstands short-circuit forces reliably
4. Superior Moisture & Pollution Resistance
• Epoxy resin encapsulation provides excellent moisture-proof, dust-proof, and salt-spray resistance
• Suitable for high-humidity, polluted, and coastal environments without performance degradation
• No pre-drying required before commissioning, even in damp storage or installation conditions
5. Low Noise & Low Partial Discharge
• High-quality amorphous alloy strip material with optimal flux density selection minimizes magnetostriction noise
• Advanced manufacturing processes control partial discharge levels below 5pC
• Vibration-damping design minimizes operational vibration and noise transmission
6. Maintenance-Free & Long Service Life
• No oil or liquid media – eliminates routine oil testing, filtration, and replacement
• Epoxy resin encapsulation protects windings from moisture, dust, and contaminants
• No core lifting inspection or periodic maintenance required – only simple exterior cleaning
