Apr 05, 2014History of SF 6. SF 6 or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that SF 6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20 th

This SF6 gas insulated switchgear working principle is the biggest advantage in the working stability and development of miniaturization and it also without any maintenance for 30 years time. SF6 gas insulated switchgear(GIS) has vacuum circuit breaker and disconnector without maintenance, which greatly reduces maintenance and inspection workload.
In order to achieve the purpose of frequent monitoring of density, SF6 circuit breakers should be equipped with SF6 gas density meters or density relays. The SF6 gas density meter is for monitoring, and the density relay is for control and protection. SF6 gas density meter installed on SF6 circuit breaker, with pointer and scale is called
superb SF6 moisture reuse manufacturers,our company's path in SF6 gas handling started in 1967, when we supplied a complete piping system for installation of the first SF6 gas insulated switchgear. Since then, our product portfolio has successively been developed to the widest product range of emission-free gas handling equipment worldwide.
Cold Weather Operating Problems with SF 6 Circuit Breakers. IEEE Standards. ANSI/IEEE C37.04-1979 1 and ANSI/IEEE C37.010-1979 2 are the standards relating to the rating structure and application of circuit breakers. There is no specific advice concerning low temperature. The standard service conditions are covered in C37.04 1, which includes altitude less than 1000m, and a temperature range
