Xrun Materials Support the 1100 kV Nanyang UHV Substation with Over Ten Years of Stable Operation

The 1000 kV Jindongnan‑Nanyang‑Jingmen UHV AC Pilot Demonstration Project represents a milestone in China’s UHV power grid development, a commercially operational UHV AC transmission line. Commissioned for commercial service in January 2009.

Shanghai Xrun supplied high‑quality epoxy resin insulation materials for GIS equipment at the Nanyang Substation of this project. After more than a decade of continuous stable service under harsh UHV operating conditions, Xrun’s products maintain outstanding electrical insulation and mechanical stability, forming a robust material foundation for the safe operation of the UHV power grid. This application highlights Xrun’s technical strength and product reliability for UHV‑grade insulation materials.
