2017/8/24Therefore, this limit does not mean that higher SF6 concentrations pose any toxic hazard. According to Clause 7.1 of IEC 60480: "In principle, a mixture of 20% of oxygen and 80% SF6 can be inhaled without adverse effect. Concentrations above 20% would cause suffocation due to lack of oxygen.

History Jack Cover, a NASA researcher, began developing the first Taser in 1969. By 1974, Cover had completed the device, which he named TASER using a loose acronym of the title of the book Tom Swift and His Electric Rifle, a book written by the Stratemeyer Syndicate under the pseudonym Victor Appleton and featuring Cover's childhood hero, Tom Swift.
High quality sf6 gas Leak Steps
High quality sf6 gas Leak StepsThe function of SF6 gas leakage monitoring system. 1. The SF6 gas leakage monitoring system can monitor the SF6 concentration in the switch room in real time. When the SF6 concentration is greater than or equal to 1000ppm, it will automatically alarm and start the fan. 2.
