Description ：

The circuit breakers are all equipped with pure spring operating mechanisms which makes structure simple and highly reliable. The mechanical endurance for the operating mechanism is over 10000 times, and it is convenient for maintenance and meets mechanism’s  requirements for oil free and air free. It uses self-energy arc extinguishing principle, and reduces operation power of the mechanism and enhance operational reliability of product. The flanges adopt dual-seal structural design, the outer seal ring is water-proof and inner seal ring is gas proof. Therefore, it can reduce the leakage of the product greatly and makes the product more suitable for outdoor operation.

Q:What is the difference between SF6 live tank and dead tank?

A:In an SF6 live tank circuit breaker, the tank is at the line potential and energized during operation. It's usually lighter and more compact. In contrast, the tank of an SF6 dead tank circuit breaker is grounded, isolating the high - voltage parts. Dead tank types often have better insulation and are suitable for higher voltages, but they tend to be larger and heavier.

Q:What is a dead tank circuit breaker?

A:A dead tank circuit breaker is an electrical device for interrupting current in power systems. Its tank is grounded, isolating it from high - voltage parts. Filled with SF6 gas for insulation and arc - quenching, it's well - suited for high - voltage applications, offering good electrical performance and safety.
