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
