13/06/2017SafeRing AirPlus was launched last year and is the first 24 kV medium-voltage RMU with an alternative to SF6 on the market. The RMU makes use of AirPlus, a new fluoroketone-based gas mixture developed by ABB in collaboration with 3M. The new gas has a global warming potential (GWP) of less than one - almost 100 percent lower than SF6.
How to Detect Insulated gas reuse in Puerto RicoOct 07, 2021A 6.4 magnitude earthquake, and subsequent aftershocks, that struck Pureto Rico in January 2020 left two-thirds of the Commonwealth's residents without power. The earthquakes significantly damaged the island's two natural gas-fired power plants.
23/11/2019Development Sf6 Alternative Gases in Switchgears. Sf6 gas is widely used in electric power transmission and distribution systems, as for example in gas insulated switchgear (GIS), circuit breakers (CB) and load break switches. It combines unique electrical insulation and arc interruption capability. However, it is also a very strong greenhouse

Sulfur hexafluoride SF6 gas hazards. Sulfur hexafluoride (SF6) is colorless, odorless, heavier than air and is not considered as toxic.However it is suffocating at high concentrations (it replaces oxygen) just like inert gases (also called noble gases). Sulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive gas mixture.
Table 4 compares detections of these SF6 peaks to appearance of PRD-1 in respective wells. In comparing PRD-1 data to SF6 tracer data (Brown 2001 ; Harden 2003), the SF6 plume, indicated by concentration peaks of SF6, was initially detected at the same most-distant point of well DsM10 at the same time as PRD-1, Day 21.

cold-weather application of gas mixture (sf6/n2, sf6/cf4 2.4 Gas Leakage Rate Today's gas-filled circuit breakers have very small leakage rates (<0.5% per year at 20oC). Sealing at low temperatures must be very carefully and precisely engineered; proper materials must be used for gaskets to ensure seals reseal effectively following
SF6 Gas purification device for subway. The recycling device is suitable for SF6 electrical equipment and GIS combined electrical equipment. According to DL/T662-1999 "Sulfur Hexafluoride Inflator and Recovery Device",the device is composed of recycling system, gas charging system, vacuum pumping system, purification system and gas storage
Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling) is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

Sulfur Hexafluoride (SF6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgear employed by the power industry. Applications for SF6 include gas insulated transmission lines and gas insulated power distribution substations.
On-site SF6 recovery service is driven by a trailer which equipped with our full set of recovery, refilling, purification equipment and measuring instrument, drive to the substandard gas compartment, perform onsite shutdown and maintenance, directly recover unqualified SF6 gas, recycle and purify them to be qualified and then return to gas compartment, the maintenance cycle is shorter, and users do not have to invest any money in purchasing SF6 gas handling device, measuring instruments and
PRINTER FRIENDLY. Government efforts to develop power related infrastructure to ensure 100% electrification rate in the rural region of Vietnam under the National Power Development Plan VII (2011-2020) along with the strengthening of urban infrastructure including housing and transportation would increase the demand for switchgears in the country.

Portable sf6 mix emissions in CameroonNov 12, 2021A recent study suggests that the UK's use of SF6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of SF6 to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.
