Outdoor Type TNB Substation Power Distribution for Power Generation Plants



Product Description


  • Box-type substations are used for power distribution in 10/0.4KV three-phase AC systems.
  • They are compact and self-contained, housing all necessary components within one or several boxes.
  • American box-type substations have a cross-shaped layout and a two-part structure, allowing for better heat dissipation and a smaller footprint compared to European box-type substations.
  • Fuses are used to protect the high-voltage side, and plastic shell automatic air circuit breakers are used to protect the low-voltage side.
  • Exposure to direct sunlight for long periods can affect the heat dissipation of plastic shell circuit breakers, potentially leading to high-voltage side faults.
  • Proper ventilation and cooling measures should be taken to prevent this issue.
