Qaboojiyaha dhejiska ayaa si ballaaran loogu adeegsadaa nidaamyada danab ee hooseeya ilaa sare, codsiyo kala duwan, waxaa jira insulators boostada xarigga iyo insulators boostada.
Insulators boostada line waxaa lagu dhejiyaa cirifka korontada ee line gudbinta. Marka loo eego adeegsiga iyo booska ay ku rakibtay tiirka, insulators boostada xarriiqdu waxay u qaybsan yihiin dhowr nooc: Tie Top Line Post Insulators, Horizontal and Vertical Line Post Insulators, Under Arm Line Post Insulators and Clamp Top Line Post insulators.
Xirmooyinka boosteejooyinka boostada waxay bixiyaan kaabayaal iyo qaab dhismeed loogu talagalay warshadaha korontada, gudbinta iyo qaybinta qaybinta, iyo tas -hiilaadka kale ee korontada ilaa 1100kV.
Xirmooyinka dhejiska waxaa laga samayn karaa porcelain iyo polymer silicone. Waxaa loogu talagalay suuqyada kala duwan waxaana loo soo saaray cabbirrada caadiga ah, si ay ula kulmaan shuruudaha korontada iyo farsamada ee IEC, heerarka ANSI ama tilmaamaha macmiilka.
