Sulfur Hexafluoride
Sulfur Hexafluoride(SF6) he kinoea kino, waihoʻoluʻu, ʻala ʻole, a ʻaʻole hiki ke puhi ʻia.ʻO ka hoʻohana mua ʻana o SF6 i ka ʻoihana uila ma ke ʻano he kinoea dielectric medium no nā mea hoʻokaʻawale kaapuni uila, nā mea hoʻololi a me nā mea uila ʻē aʻe, e hoʻololi pinepine ana i nā mea hoʻoheheʻe ʻaila piha (OCBs) hiki ke loaʻa nā PCB pōʻino.Hoʻohana ʻia ke kinoea SF6 ma lalo o ke kaomi ma ke ʻano he insulator i loko o ke kinoea insulated switchgear (GIS) no ka mea he ʻoi aku ka ʻoi aku o ka ikaika dielectric ma mua o ka ea a i ʻole ka nitrogen maloʻo.Hiki i kēia waiwai ke hoʻemi nui i ka nui o nā mea uila.

Loaʻa maʻamau ka Sulfur hexafluoride (SF6) i loko o nā pahu pahu a me nā pahu pahu.Hoʻohana maʻamau ia i kekahi mau ʻoihana e like me:
1) Mana & Energy: Hoʻohana mua ʻia ma ke ʻano he insulating medium no kahi ākea o nā uila uila a me nā lako uila e like me nā mea hoʻokaʻawale kaapuni, nā mea hoʻololi a me nā mea hoʻolalelale.
2) Ke aniani: ʻO nā puka makani insulating - hoʻemi ʻia ke kani kani a me ka hoʻoili wela.
3) Steel & Metals: I ka hoʻoheheʻe magnesium a me ka alumini hana a me ka hoʻomaʻemaʻe.
4) Electronics: Hexafluoride sulfur maʻemaʻe kiʻekiʻe i hoʻohana ʻia i nā noi uila a me semiconductor.
