Product Overview

  • Model Interpretation

    The design serial number "18" incorporates cutting-edge technologies tailored for high-end dry-type transformers: ultra-thin iron cores, which minimize magnetic loss to a market-leading level while reducing the equipment’s carbon footprint; and high-efficiency winding processes that optimize energy transfer efficiency and lower long-term thermal stress on components. As a high-end customized variant, the suffix "NX1" likely includes compliance-focused enhancements—such as integrated noise-canceling systems (meeting the strict acoustic standards of healthcare and educational facilities) and reinforced short-circuit withstand structures (aligning with industrial safety regulations for critical infrastructure). "Energy Efficiency Class 1", the top national energy efficiency rating, reduces energy consumption by an additional 8%-12% compared to Class 2. This not only meets the rigorous energy-saving mandates of eco-certified zones (e.g., LEED-certified buildings) and high-standard industrial parks but also supports users in achieving carbon reduction targets.
