Enwere ọtụtụ ụdị mkpuchi ihe, nke nwere ike kewaa ụzọ atọ: gas, mmiri mmiri na ihe siri ike. Ihe mkpuchi gas a na-ejikarị gụnyere ikuku, nitrogen, na sọlfọ hexafluoride na-ekpuchi ihe nkiri PC. Ihe mkpuchi mmiri na-agụnyekarị mmanụ mkpuchi ịnweta na mmanụ sịntetik (mmanụ silicone, dodecylbenzene, polyisobutylene, isopropyl biphenyl, diarylethan, wdg). Enwere ike kewaa ihe mkpuchi siri ike ụzọ abụọ: organic na inorganic. Organic siri ike mkpuchi ihe na-agụnye ikpuchi agba, mkpuchi gluu, mkpuchi akwụkwọ, insulating eriri ngwaahịa, rọba, roba, varnished ọkpọkọ na insulating impregnated eriri ngwaahịa, eletriki ihe nkiri, mejupụtara ngwaahịa na nrapado teepu, eletriki laminates, wdg Inorganic siri ike mkpuchi ihe tumadi. gụnyere mica, glass, ceramics na ngwaahịa ha.
