Technological breakthroughs inject a 'booster' into the new power grid!

High voltage switchgear is known as the "guardian angel" of the power system. It can connect or cut off current during normal operation, and can instantly cut off huge currents in case of faults such as short circuits, protecting the safety of the entire power grid. Among them, the high-voltage circuit breaker is its core, undertaking the dual mission of control and protection.
The wave of technological innovation is sweeping across the entire industry. To adapt to the challenges brought by large-scale new energy grid integration in the future, the international first 800 kV and 80 kA high-capacity circuit breaker has been successfully developed and certified at the national level. The performance of this product meets the highest international standards and can solve the problem of short-circuit current exceeding the standard faced by the Northwest 750 kV power grid, greatly improving the transmission capacity and safety and stability level of the power grid.

At the same time, "green manufacturing" has also become the main line of development. In Wuhan, the world's largest 126 kV vacuum environmentally friendly high-voltage switchgear has been put into mass operation. It fully replaces the strong greenhouse gas sulfur hexafluoride (SF6) that has been used for more than half a century with clean air, and is expected to reduce carbon dioxide emissions by about 100000 tons throughout its lifecycle, making substation operations more environmentally friendly.
