Sulfur Hexafluoride
Sulfur HexafluorideO le (SF6) o se kesi e le o se mea ola, e leai se lanu, e leai se manogi, ma e le mu. O le fa'aoga autu o le SF6 o lo'o i totonu o le alamanuia eletise o se kesi dielectric medium mo le tele o voltage circuit breakers, switchgear ma isi masini eletise, e masani ona sui ai le oil filled circuit breakers (OCBs) e mafai ona i ai ni PCB matautia. O le kesi SF6 i lalo o le mamafa e fa'aaogaina o se insulator i le gas insulated switchgear (GIS) aua e sili atu lona malosi dielectric nai lo le ea po'o le dry nitrogen. O lenei meatotino e mafai ai ona fa'aitiitia tele le tele o le eletise.

E masani ona maua le sulfur hexafluoride (SF6) i totonu o silini ma tane o le tane. E masani ona faʻaaogaina i nisi o alamanuia e aofia ai:
1) Malosiaga ma le Malosiaga: E fa'aaogaina tele o se mea e taofia ai le eletise mai le eletise ma mea fa'aeletoronika e pei o mea e taofi ai eletise, mea e sui ai le eletise ma mea e fa'atele ai le eletise.
2) Tioata: Fa'amalama e puipuia ai le ea - fa'aitiitia ai le fesiita'iga o le leo ma le vevela.
3) Uamea ma U'amea: I le gaosiga ma le fa'amamāina o le magnesium ma le alumini ua liusuavai.
4) Mea Fa'aeletoronika: Sulfur hexafluoride mama maualuga e fa'aaogaina i mea fa'aeletoronika ma semiconductor.

Fa'amatalaga
1) o faʻamatalaga faʻapitoa uma o loʻo faʻaalia i luga e mo lau faʻasinomaga.
2) e talia ma le fiafia nisi fa'amatalaga fa'aopoopo mo nisi talanoaga.
