Product Overview
  • Key Power Grid Distribution Lines: For power grid companies, transformers deployed on critical distribution lines (e.g., those supplying urban central areas or key industrial zones) require high efficiency and reliability. The ultra-low loss and intelligent monitoring features of this product ensure stable power supply while reducing grid operating costs.
  • Large-Scale Industrial Parks: Industrial parks with high energy consumption (e.g., manufacturing hubs, high-tech industrial zones) have strict demands for energy efficiency to control production costs. The transformer’s energy-saving performance helps enterprises meet energy conservation targets and comply with environmental regulations, while its high load-carrying capacity adapts to the fluctuating power needs of industrial equipment.
  • New Energy Grid-Connection Systems: In photovoltaic (PV) or wind power generation projects, the transformer plays a crucial role in converting and distributing the generated electricity to the grid. Its high efficiency minimizes energy loss during the grid-connection process, and the intelligent monitoring system ensures compatibility with the intermittent nature of renewable energy sources, maintaining stable power quality.
  • Green Building Complexes: Modern green building complexes (e.g., eco-friendly residential areas, LEED-certified commercial buildings) prioritize energy efficiency and environmental sustainability. This transformer’s low energy consumption and eco-friendly design align with the green standards of such projects, contributing to their overall environmental performance ratings.200kVA 20kV Oil-immersed Distribution Transformer S(B)13-NX3 Energy Efficiency Level 3
