SF6 dead tank circuit breakers are equipped with pure spring operating mechanisms which make the structure simple and highly reliable. The mechanical strength of the operating mechanism is more than 10000 times, it is convenient for maintenance and meets the requirements of oil-free and air-free mechanism. It uses the principle of self-energy arc extinguishing and reduces the operating power of the mechanism and improves the operational reliability of the product.
