The LW8-35 outdoor high-voltage SF6 circuit breaker, independently developed by Taikai, has been awarded the National Science and Technology Progress Award (Third Prize) and has consistently held the leading market share in China for years. This breaker features a self-energizing arc-extinguishing design based on the "thermal expansion + blow-assisted" principle and is equipped with a CT14 spring operating mechanism. It delivers exceptional breaking performance, a short arcing time, and an extended electrical lifespan. To date, more than 20,000 units have been successfully deployed across various levels of the national power grid.
