Swiss supercapacitors drive Chinese 550kV DC meshed grid
High voltage supercapacitors made in Switzerland are being used for DC circuit breaker and DC voltage divider applications in a meshed power grid project in ZhangBei, China. The project will send power to the capital, Beijing, from a variety of renewable sources including wind and solar power.
a participant in the ZhangBei DC Grid Project. "The ZhangBei project will supply enough power on the grid to manage the increasing demand for high energy without breakdown of the grid. The technology provided by CONDIS capacitors will aid us in minimizing disruptions by increasing the number of lines and substations."

The long term stability, temperature control and insulation design of the HV supercapacitors and voltage dividers help handle variable working conditions in high altitude HVDC substations such as Zhangbei.
