The GIS is a high-voltage switchgear with gas-insulated gas insulation, designed to receive, distribute and transmit electrical energy in networks of three-phase alternating current frequency of 50 Hz rated voltage of 110 kV. GIS switchgear cell of YATE-110 type is a complex of modules: circuit breaker, combined disconnector-earthing switches, quick-acting earthing switch, current transformers, connecting elements, cable or air bushings, current conduits, etc., placed in a metal shell filled with gas-insulated gas.
Switchgear with YATE-110 cells is designed for use in substations and power plants at ambient temperatures down to -45 degrees C. Factory delivery of the cell is carried out in a fully assembled form, which allows to significantly reduce the time of commissioning of the facility as a whole.
