Ⅰ. Core Pain Points
Urban CBD supertall buildings face two critical challenges:
• Noise Control Difficulty: Traditional transformers' no-load noise (>55dB) disrupts premium office environments, violating green building acoustic standards.
• Premium Space Constraints: Electrical room costs exceed ¥100,000 per square meter; large traditional transformers encroach on core functional areas.
Application Scenarios: 500m+ supertall landmarks, LEED Gold-certified office towers, international financial centers.
II. Customized Solution Design
1. Acoustic Optimization System (Noise ≤45dB(A))
Technical Module
Innovative Design
Performance Gain
Magnetic Noise Reduction
Stepped-lap core joints + 27QG110 high-permeability silicon steel
≤45dB(A) no-load noise ▼ 18% below national standard
Vibration Control
Resilient shock pads + Nano-fiber sound-absorbing panels
8dB structural noise transmission reduction
▶ Achieved Outcome: Operating sound pressure level lower than a library environment (50dB), compliant with ISO 3744 indoor acoustic certification.
2. Space Compression Technology (+20% Power Density)
Coil Foil Winding Process: 0.05mm ultra-thin copper foil lamination technology
→ 15% eddy current loss reduction
3D Cooling Channels: Vertical air ducts + honeycomb radiators
→ 30% thermal efficiency improvement
Footprint Comparison (2500kVA):
Traditional Transformer: ≥ 3.8m²
This Solution: 3.0m² ▼ 21% space saving
3. Fire Safety Assurance (Zero Hazardous Emissions)
Insulation System: UL-certified CERADUR® eco-friendly resin
Fire Resistance: Passes 950℃ open flame test
