Sọlfọ Hexafluoride
Sọlfọ Hexafluoride(SF6) bụ gas na-adịghị n'ime ahụ, enweghị agba, enweghị isi, na nke na-anaghị ere ọkụ. A na-ejikarị SF6 eme ihe n'ụlọ ọrụ eletriki dị ka ihe na-eme ka ọkụ eletrik dị iche iche na-agbaji voltaji, switchgear na ngwa eletriki ndị ọzọ, na-anọchikarị ihe na-eme ka ọkụ eletrik jupụtara na mmanụ (OCBs) nke nwere ike ịnwe PCB ndị na-emerụ ahụ. A na-eji gas SF6 n'okpuru nrụgide eme ihe dị ka ihe na-egbochi ọkụ eletrik na switchgear gas insulated (GIS) n'ihi na ọ nwere ike dielectric dị elu karịa ikuku ma ọ bụ nitrogen akọrọ. Ihe onwunwe a na-eme ka o kwe omume ibelata nha nke gia eletriki nke ukwuu.

A na-enwetakarị sọlfọ hexafluoride (SF6) n'ime silinda na tankị drum. A na-ejikarị ya eme ihe n'ụfọdụ ụlọ ọrụ gụnyere:
1) Ike na Ike: A na-ejikarị ya eme ihe dị ka ihe mkpuchi maka ọtụtụ ngwa eletriki na eletrọniki dị elu dịka ihe mgbawa sekit, gia mgbanwe na ihe na-eme ka ihe dị mfe.
2) Iko: Windo na-ekpuchi ihe - mbelata nnyefe ụda na nnyefe okpomọkụ.
3) Ígwè na Ígwè: N'ime mmepụta na nhicha nke magnesium na aluminom gbazere agbaze.
4) Eletrọniki: Sulfur hexafluoride dị ọcha nke e ji eme ihe n'ọrụ eletrọniki na semiconductor.
