Product Overview
  • Model Interpretation

    The design serial number "18" incorporates cutting-edge technologies tailored for high-performance dry-type transformers: ultra-thin iron cores, which minimize magnetic flux loss to an industry-leading level, and high-efficiency winding processes that optimize current transmission efficiency while reducing internal heat generation. As a high-end customized model, the suffix "NX1" likely includes value-added features such as advanced noise dampening systems (critical for noise-sensitive environments) and reinforced short-circuit withstand capacity (enhancing fault resilience). "Energy Efficiency Class 1"—the highest energy efficiency rating in national standards—cuts energy consumption by an additional 8%-12% compared to Class 2. This not only meets the stringent energy-saving criteria of eco-sensitive zones or high-standard industrial parks but also contributes to long-term carbon footprint reduction for users.
