HENTG's S13 is a self-developed transformer evolved from the S11 model. Through the application of new materials and technologies, integration of independent innovation and technology introduction, as well as optimized core and coil structure design, it achieves reduced no-load loss. Its noise level averages a 20% decrease compared with the national standard JB/T10088-2004, with performance reaching the domestic advanced level.

Applications
  • Urban & rural distribution networks
  • Industrial and mining enterprises
  • Commercial buildings & real estate projects
  • Solar and wind energy substations
  • Transportation infrastructure (e.g., airports, railways)
