Masu kera bututun Epoxy sun bayyana halaye na kayan rufewa daban-daban:

akwai nau’ikan kayan rufewa da yawa, wanda za a iya raba kashi uku: gas, ruwa da kuma m. Abubuwan da aka saba amfani da su na rufe fuska sun haɗa da iska, nitrogen, da sulfur hexafluoride mai hana fina-finan PC. Abubuwan da ke hana ruwa ruwa sun haɗa da mai da ke hana ma’adinai da mai da ke hana ruwa (man siliki, dodecylbenzene, polyisobutylene, isopropyl biphenyl, diarylethan, da sauransu). Za a iya raba ƙaƙƙarfan kayan rufewa zuwa nau’i biyu: Organic da inorganic. Organic m insulating kayan sun hada da insulating fenti, insulating manne, insulating takarda, insulating fiber kayayyakin, robobi, roba, varnished bututu da insulating impregnated fiber kayayyakin, lantarki fina-finan, composite kayayyakin da m kaset, lantarki laminates, da dai sauransu Inorganic m insulating kayan yafi. sun hada da mica, gilashi, yumbura da samfuran su. Sabanin haka, m kayan rufewa suna da bambanci kuma mafi mahimmanci.

Kayan aikin lantarki daban-daban suna da buƙatu daban-daban don aiwatar da kayan rufewa. Ana buƙatar kayan haɓaka don na’urorin lantarki masu ƙarfin lantarki kamar na’urori masu ƙarfin lantarki da igiyoyi masu ƙarfin lantarki don samun ƙarfin rushewa da ƙananan asarar dielectric. Ƙananan kayan lantarki na lantarki suna ɗaukar ƙarfin injiniya, haɓakawa a lokacin hutu, ƙimar juriya na zafi, da dai sauransu a matsayin babban buƙatun.
