ZF16-252(L)/Y4000-50 Gas Insulated Switchgear

ZF16-252(L)/Y4000-50 Gas Insulated Switchgear

  1 Overview
  ZF16-252(L)/Y4000-50 Gas Insulated Metal-Enclosed Switchgear (hereinafter referred as GIS) is applicable for the electrical system with features of three phases AC, 50Hz, and rated voltage of 252kV.
  The GIS meets the relative requirements of national standard - GB7674-2008 and international standard IEC60517. All the components inside the GIS conform to the corresponding national standard.
  The three-phase main busbars of GIS share one common enclosure, while all the other compo-nents are separated in three different compartment.
