The 110kV Smart & Energy-Efficient Power Transformer is a next-generation solution engineered by integrating global advanced technologies and proven manufacturing expertise. Designed for the smart grid era, it fully complies with the latest Chinese national standards (GB1094 series) and international IEC recommendations. This transformer not only features built-in intelligent monitoring and diagnostic capabilities but also achieves a breakthrough in energy efficiency, with no-load loss reduced by over 35% compared to the national benchmark. It represents the ideal core equipment for building reliable, economical, and future-proof power infrastructure.
Key Features & Benefits
• IoT-Ready & Smart Monitoring
Equipped with digital interfaces and a self-aware condition management system, it enables real-time diagnostics, assessment, and control. Facilitates integrated grid-device management for predictive maintenance and optimized operation.
• Superior Energy Savings
Constructed with high-grade grain-oriented silicon steel and employing advanced core design (step-lap joints, no-hole punching, non-lapped yoke), it achieves exceptional efficiency. No-load loss is reduced by more than 35% against GB/T6451-2008, offering significant lifecycle cost savings.
• Enhanced Robustness & Safety
Features a unique corrugated tank wall (seamless welding) and a rigid "Six-Side Positioning" system for the core assembly. Combined with a separate tap winding design for better ampere-turn balance, it ensures remarkable mechanical strength, superior short-circuit withstand capability, and safe transport.
• Optimized Cooling & Low Noise
An internal zigzag oil guide structure ensures even cooling across all winding sections. The corrugated tank and panel radiators increase heat dissipation area, while the core design and tank shape effectively reduce audible noise levels.
• Long-Life & Maintenance-Friendly Design
A bellows-type conservator slows down oil aging, and a magnetic oil level gauge ensures accurate reading. High-quality seals, double-gasketed or welded flanges (upon request), and specially treated paint provide excellent environmental protection and durability.
• Premium Manufacturing & Quality Control
Core assembly and winding are conducted in a fully enclosed, cleanroom environment. All insulating materials undergo strict, controlled drying and sealing processes. Key components can be sourced from leading international suppliers per customer requirements.
