Siemens Energy and Mitsubishi Electric have signed an MoU to conduct a feasibility study on the joint development of high-voltage switching solutions with zero global-warming potential (GWP) in the high-voltage power transmission industry. …
The solutions are expected to substitute greenhouse gases with clean air for insulation. They companies will research methods for scaling up the application of clean air insulation technology to higher voltages. They have planned to start with a 245-kV dead-tank circuit breaker that will speed up the availability of climate-neutral high-voltage switching solutions for customers around the globe. Both the companies will be manufacturing and selling the service switchgear solutions independently.
