Product Description
1. High Efficiency & Maximized ROI
Ultra-Low Loss Design: Premium grain-oriented silicon steel + step-lap core technology reduces no-load losses by 20% and load losses by 15% vs. national standards.
Smart Thermal Management: Auto-start forced-air cooling keeps winding temperature rise ≤55K, extending insulation life by up to 30%.
Wide Voltage Adaptation: On-load tap changer (±2×2.5%) automatically compensates for grid fluctuations—minimizing energy loss and maximizing yield.
2. Rugged Protection for All Environments
Extreme Climate Ready:
High Altitude: Stable operation above 3,000m with 15% enhanced insulation strength.
Corrosion Resistant: C4-grade coating + stainless fasteners withstand 2,000+ hours of salt spray.
Arctic Performance: Reliable startup at –40°C with integrated oil-tank heating.
Multi-Layer Safety:
IP54 Enclosure (dust & water resistant)
UL94 V-0 Flame-Retardant Materials
Advanced Surge Protection: Multi-stage arresters with voltage protection ratio ≤1.5
3. Modular & Fast Deployment
Factory-Integrated: Transformer, HV/LV switchgear, and monitoring system pre-assembled—70% faster on-site installation.
Space-Smart Design: Compact footprint (3,600 × 2,200 × 2,500 mm) fits rooftops, carports, and confined sites.
Plug-and-Play Ready: Standardized interfaces for quick connection to inverters and the grid.
4. Intelligent Operation & Full Visibility
Real-Time Health Monitoring: Tracks 12+ parameters—oil temp, winding temp, oil level, partial discharge, etc.
AI-Powered Predictive Alerts: Detects insulation aging or loose connections up to 14 days in advance.
Remote Control & Cloud Integration:
Seamless SCADA/EMS compatibility
Real-time performance & health data via mobile app
