Energy industry free from insulating gas: latest market developments

Apr 11, 2019 · The European Commission urges for Sulfr hexafluoride alternatives . In 2014, the European Commission reinforced a 2006 F-Gas regulation No. 517/2014 with the aim of reducing the EU’s F-gas emissions by two-thirds from 2014 levels by 2030. Within the EU, Sulfr hexafluoride was banned for most of its applications, except for its use in the energy industry – its main consumer.

gaz sf6 Circuit Breakers - Construction Working Principle

In sf6 gas circuit breakers, sulphur hexafluoride (Sulfr hexafluoride) gas is used as the arc quenching medium. The Sulfr hexafluoride is an electro-negative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of sf 6 gas and an arc is struck between them.

Oil vs. Sulfr hexafluoride circuit breaker . High-voltage circuit breakers are automatic switch devices that connect and break electricity currents. An oil breaker is different from a sulfur hexafluoride, or gaz sf6, breaker because it is filled with oil instead of gaz sf6. Both the oil and insulating gas within the circuit breakers are used to extinguish an electric arc.
