- Ideal for urban and residential environments
Superior Copper Windings
- Manufactured from 9% pure oxygen-free copper
- Enhanced mechanical strength for short-circuit and surge resistance
- Optimized for stable voltage performance under varying loads
Vapor Phase Drying (VPD) Technology
- Moisture content maintained below 5%
- Prevents insulation aging and oil degradation
- Ensures long-term reliability and maintenance-free operation
Advanced Cooling & Heat Dissipation
- Corrugated walls or plate-type radiators for efficient heat transfer
- Hot-dip galvanized surfaces for corrosion resistance
Hermetically Sealed Tank Design
- Prevents contact between oil and atmosphere
- Eliminates oxidation and moisture contamination
- Extends transformer lifespan significantly
ONAN Cooling System
- Oil Natural Air Natural (ONAN) cooling
- No external power required
- Reliable performance during peak load conditions
Designed for modern grid requirements, our transformers support advanced monitoring and protection systems.
- Pressure Relief Devices (PRD)
Prevent tank rupture during internal faults - Oil & Winding Temperature Indicators (OTI/WTI)
