SF6 gas / SF6 gas quality
Frequently Asked Questions
Is SF6 harmful to health?
Pure SF6 is physiologically completely harmless. Due to its weight (5 times heavier than air) it might displace the oxygen in the air if large quantities are concentrating in deeper and non ventilated places. Legislation for chemicals does not categorise SF6 as hazardous material.
Why is SF6 used in electric power equipment?
SF6 is a very good electric insulator with excellent arc quenching properties. This is why SF6 is used in gas insulated switchgear and other electric power equipment such as bus bars. Other applications are medium and high voltage switchgear as well as gas insulated lines (GIL).
What do I need to watch out for during gas measurement?
In order to ensure a proper measurement result in practice, attention should be paid to the following:
For measurements performed on gas cylinders with liquid SF6,
- we recommend only using a pressure regulator with metal membranes,
- do not use any rubber hoses,
- only use self-closing couplings.
How can decomposition products in the gas be removed?
Gaseous decomposition products can be filtered out using dry filters and decomposition products in the form of dust can be filtered out using particle filters. This occurs automatically during the recovery and filling process with a DILO service cart.
