Metal Switchgear and RMU. 12/24kV Full gas insulated RMU. RMR is a full gas ring main unit for the secondary distribution network. RMR can be supplied in 10 different configurations suitable for most switching applications in 12/24 kV distribution networks. It complies IEC60420, GB/T11022, GB3804,GB3906 with high quality.

5/11/2017Working Principle of Sulfr hexafluoride Circuit Breaker. The contacts of gaz sf6 Circuit Breaker are surrounded in an environment of insulating gas gas at some pressure. Actually, the dielectric strength of Sulfr hexafluoride 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.

10/11/2021Sulfur hexafluoride (Sulfr hexafluoride) is not nearly as infamous as CO2, with the latter getting most of the blame for anthropogenic climate change. Yet while measures are being implemented to curb the release

Sulfur Hexafluoride (sf 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas, and an excellent electrical insulator. sf 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.
