Abstract

The GIL covered voltage levels from 110 kV to 1000 kV. For Yellow River Laxiwa Hydropower Station, it´s first 800 kV power plant in China. It´s located at altitude of 2300-2500 meters. In high voltage and high altitude areas, normal XLPE cable was limited to be used. This paper introduces particular issues of 800 kV GIL in construction, design, manufacturing, erection and commissioning. And gives special recommendations for GIL applied in high fall vertical shaft and high altitude region.
