oem transporting sf6 gas North Korea

The generation cycle within the sf 6 circuit breaker is not at all complicated – first, gas compression and storage in a highly pressurized reservoir must manifest. Next, the compressed gas is slowly released and settles in the low pressure tank then, reutilized once pumped back to the pressurized reservoir.

Operation and working principle of sf6 gas Circuit Breaker By Learn Electrical

where can I get 220kv sf6 circuit breaker Hong Kong,5/11/2017Working Principle of insulating gas Circuit Breaker. The contacts of sf6 gas Circuit Breaker are surrounded in an environment of sf 6 gas at some pressure. Actually, the dielectric strength of sf 6 gas is directly proportional to its pressure. In 220 kV, 400 kV and 765 kV applications, the gas pressure is maintained at 6.5 bar.

Sulfur hexafluoride (gaz sf6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. Sulfr hexafluoride has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.
