Sulfur Hexafluoride
Sulfur Hexafluoride(SF6) ose kasa e le fa'aola, e leai se lanu, e leai se manogi, ma e le mafai ona mu.SF6 fa'aoga muamua o lo'o i totonu o le alamanuia eletise e pei o se ala dielectric kasa mo va'aiga ta'amilosaga eseese, switchgear ma isi mea fa'aeletise, e masani ona sui ai le suau'u fa'atumuina va'ava'a (OCBs) e mafai ona aofia ai PCBs leaga.SF6 kasa i lalo o le mamafa o loʻo faʻaaogaina e avea o se insulator i le kesi insulated switchgear (GIS) ona e sili atu lona malosi dielectric nai lo le ea poʻo le nitrogen mago.O lenei meatotino e mafai ai ona faʻaitiitia le tele o le mea eletise.

Sulfur hexafluoride (SF6) e masani ona maua i totonu o fagu ma tane pa'u.E masani ona faʻaaogaina i nisi o alamanuia e aofia ai:
1) Malosiaga & Malosiaga: Fa'aaoga muamua e fai ma ala fa'amama mo le tele o mea eletise eletise ma mea fa'aeletoroni e pei o va'ava'ava'a, sui o mea ma mea fa'avave.
2) tioata: fa'amalama fa'amalama - fa'aitiitia le leo ma le vevela.
3) Uamea & Uamea: I le gaosiga o le magnesium ma le alumini ma le faʻamamaina.
4) Fa'aeletonika: maualuga le mama sulfur hexafluoride fa'aaogaina i fa'aoga eletise ma semiconductor.
