- Product Type: Ultra-energy-saving oil-immersed distribution transformer, conforming to the requirements for high-energy-saving power distribution equipment under the national "dual carbon" goal.
- Model Interpretation: The design serial number "22" applies cutting-edge technologies for oil-immersed transformers, such as amorphous alloy cores, high thermal conductivity insulating oil, and three-dimensional wound cores; "NX1" is a high-end model, possibly including environmentally friendly insulating oil (e.g., plant-based insulating oil, biodegradable) and intelligent monitoring modules (for real-time monitoring of oil temperature and load); "Energy Efficiency Class 1" is the highest energy efficiency level for oil-immersed transformers, reducing energy consumption by 10%-15% compared to Class 2.
- Core Advantages & Application Scenarios: It features ultra-low loss (no-load loss is only 60%-70% of that of ordinary S13 models), excellent environmental performance, and strong adaptability to intelligent operation and maintenance. Some models are eligible for energy-saving subsidies. It is suitable for key distribution lines of power grid companies, large industrial parks, and new energy supporting power distribution (e.g., photovoltaic/wind power grid connection) scenarios with high requirements on energy efficiency, environmental protection, and intelligence.
