  • Product overview:

    11kV Dry Type Transformer – Energy Saving, Fire Safe, Global Universal Certified
    This 11kV dry type transformer is tailored for global mainstream 11kV power grid systems, widely adopted in Southeast Asia, Africa, the Middle East and rural & urban distribution networks. With low loss, full fire safety and global standard compliance, it delivers high stability and cost performance for global industrial, commercial and civil power supply projects.

    - Low Loss & Energy Saving – 30% lower power loss than traditional SCB11 11kV transformers, greatly reducing grid operation and electricity costs.
    - Beyond Global Standards – Actual performance exceeds IEC, GB, EN and IEEE standards, fully adapting to 11kV grid technical specifications of different countries.
    - Full Global Certification – Approved with CB, CCC, KEMA, SASO, CE and other authoritative certifications, supporting quick market access for most global regions.
    - High-Level Fire Safety – F1 fire class rating with excellent flame retardant and self-extinguishing performance, non-toxic and pollution-free, suitable for densely populated and high-standard fire protection scenarios.
    - Excellent Surge Withstand – Equipped with 95kV lightning impulse resistance for 11kV models, effectively resisting lightning strikes and grid voltage fluctuations in complex operating environments.
    - Intelligent Load Adaptation – Built-in intelligent temperature control system and forced air cooling device, supporting stable continuous operation at 120% rated load to cope with peak power consumption.
    - Global Field Reliability – Fully compatible with universal 11kV grid standards, with stable operating experience verified in more than 50 countries worldwide.
    - Wide Application Coverage – Perfect for 11kV urban & rural distribution networks, industrial factories, mining projects, commercial buildings and public infrastructure.
    - Proven Export Track Record – Mass delivery of qualified units to Southeast Asia, the Middle East, Africa, South America and other regions with long-term stable operation.
    - Complete Standard Compliance – Strictly in line with IEC 60076 series, GB 1094 series and GB/T 6451-2008 core industry standards.
    - Diversified Protection Options – Optional aluminum alloy, cold rolled steel and stainless steel enclosures, with IP20 and IP23 protection grades for different indoor and outdoor environments.
