The GIS insulating rod is a critical component of gas-insulated switchgear, requiring both high insulation performance and robust mechanical strength.

The GIS insulating pull rod is a critical component of gas-insulated switchgear, requiring both superior insulation performance and robust mechanical strength. China has successfully developed ultra-high-voltage GIS insulating pull rods rated from 363 kV to 1100 kV, which passed evaluation in May 2024. These rods boast comprehensive performance that finally breaks the long-standing reliance on imported components, providing essential support for ultra-high-voltage engineering projects.
