Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm iav insulator thiab porcelain insulator: iav insulator lub insulator ntaus ntawv yog ua los ntawm iav, uas yog hu ua iav insulator; Tam sim no, toughened iav insulators yog siv dav hauv cov kab sib kis. Porcelain insulator yog ua los ntawm hluav taws xob ceramics. Ceramic insulator yog thawj zaug insulator. Cov txheej txheem yog qhov yooj yim, tab sis nws tsis muaj qhov zoo dua uas nws tsis yooj yim rau khaws cov pa phem. Qhov tseeb, cov pa phem ntawm ceramic insulator ntawm qhov chaw kuj tseem hnyav heev. Piv nrog rau ceramic insulator, qhov zoo tshaj plaws ntawm iav insulator yog tias nws tsis xav tau xoom tus nqi kuaj pom, thiab xoom tus nqi iav insulator yuav nws tus kheej tawg.
Iav insulator: nws muaj cov khoom siv hluav taws xob zoo thiab hluav taws xob, thiab nws lub zog tensile, hluav taws xob tawg tsis kam, kev co qaug zog tsis kam, arc hlawv tsis kam thiab txias thiab kub poob siab kuj zoo dua li cov plooj (porcelain insulator). Sib txawv ntawm cov porcelain insulators, iav insulators muaj lub rwb thaiv tsev tus kheej tshem tawm muaj peev xwm ntawm xoom tus nqi tawg, uas yog ib qho yooj yim mus nrhiav tsis muaj kev ntsuas rwb thaiv tsev. Tus kheej tawg tus nqi feem ntau yog siab dua nyob rau hauv thawj peb lub xyoos, uas yog opposite rau cov porcelain insulators. Ntau xyoo ntawm kev ua haujlwm thiab cov ntaub ntawv xeem qhia tau tias cov iav tempered insulators muaj cov khoom siv hluav taws xob ruaj khov thiab lub neej ntev.
Ceramic insulator: nws muaj qhov zoo ntawm kev ua haujlwm zoo rwb thaiv tsev, kev hloov pauv huab cua, tiv thaiv tshav kub thiab hloov tau yooj yim. Nws yog dav siv nyob rau hauv kab ntawm ntau theem voltage. Disc porcelain insulator belongs rau hom kev tawg. Nws yog tsim los ntawm cov plooj (porcelain) thiab hlau qhov chaw nrog cov khoom sib txawv ntawm lub cev thiab tshuaj lom neeg sib txuas los ntawm cov cement. Nws yuav maj mam deteriorate thiab ua rau muaj kev hem thawj rau kev nyab xeeb ntawm daim phiaj hluav taws xob tom qab lub sij hawm ntev raug rau hluav taws xob teb, mechanical load thiab ntuj tshav ntuj, cua, nag, daus thiab pos huab. Tshwj xeeb, nyob rau hauv cov ntaub ntawv ntawm flashover ntawm insulator hlua uas muaj deteriorated insulator (vim xob laim tawm tsam los yog muaj kuab paug flashover, thiab lwm yam), lub taub hau ntawm deteriorated insulator yuav rhuab thiab tawg tam sim ntawd, ua rau muaj kev huam yuaj ntawm tus neeg xyuas pib tsaws. Qhov zoo thiab qhov tsis zoo ntawm iav insulator thiab porcelain insulator tuaj yeem sib piv. Cov iav insulator thiab porcelain insulator tuaj yeem siv tau raws li kab tsim.
