Ana amfani da insulators na gidan waya a cikin ƙananan zuwa manyan tsarin wutar lantarki, don aikace -aikace daban -daban, akwai masu rufewa na layin layi da masu rufe gidan.
An saka insulators na layin layi akan sandar lantarki don layin watsawa. Dangane da amfani da matsayin da aka sanya a kan gungumen, an raba masu rufe layin bayan gida zuwa iri iri: Tie Top Line Post Insulators, Horizontal and Vertical Line Post Insulators, Under Arm Line Post Insulators and Clamp Top Line Post insulators.
Masu ba da sabis na tashar tashoshi suna ba da rufi da tallafi na tsarin wutar lantarki, watsawa da rarraba tashoshi, da sauran wuraren wutar lantarki har zuwa 1100kV.
Za'a iya yin insulators na bayan gida da polymer silicone. An ƙera su don kasuwanni daban -daban kuma ana ƙera su zuwa daidaitattun girma, don haka za su iya biyan buƙatun lantarki da na inji na IEC, ƙimar ANSI ko ƙayyadaddun abokin ciniki.
