330kV three-phase on-load tap-changer autotransformer

OSFSZ-360000/330
This product is a 330kV three-phase oil-immersed on-load tap-changer auto-transformer independently developed and designed by TBEA. It is one of the key equipment in 330kV voltage level power transmission and transformation projects. Its function is to connect power grids of different voltage levels and meet the needs of the power system by adjusting the output voltage.

  • Product Advantages
    Compact structure, reduced footprint.
    The high-voltage outgoing line device adopts a conventional layout, facilitating on-site installation.
    The radiator is directly hung on the body, resulting in a low temperature rise during operation.
    Safe and stable, with reliable operation.
  • Application Scenarios
    This product can be applied to 330kV voltage level transmission and transformation lines, providing strong support for long-distance, cross-regional, and large-capacity energy transmission.
