Get PriceSF6 gas. Sulfur hexafluoride - SF6 is an industrially produced gas with excellent dielectric and arc quenching properties. The gas is mainly used as insulation and breaking medium in e.g. switchgear, transformers and switches for high and medium voltage. SF6-filled electronic equipment are closed systems that provide no direct emissions.People also askWhat is a gas cart leak?What is a gas cart leak?gas carts, which are used to remove, store, clean, and re-fill SF6gas to high-voltage equipment, are considered a major source of handling-related losses.
