Insulators siv nyob rau hauv cov kab sib kis tau muab faib ua ob pawg: disc ncua kev kawm ntawv thiab qws ncua kev kawm ntawv raws li lawv cov qauv, thaum raws li kev faib tawm ntawm cov ntaub ntawv dielectric, muaj peb hom insulators: porcelain, iav thiab organic hluavtaws insulators.
Cov hluav taws xob plooj (porcelain) ntawm disc-shaped suspension porcelain insulator yog porcelain piece ua los ntawm quartz xuab zeb, av nplaum, feldspar thiab lwm yam ntaub ntawv raw los ntawm pob milling, pulping, av nkos refining, sib sau, glazing thiab sintering. Nws yog bonded nrog steel cap thiab steel ko taw los ntawm qib high-qib cement los ua lub hau taw disc-zoo li raug tshem tawm porcelain insulator. Lub hau steel thiab steel ko taw dais cov neeg kho tshuab nro, cov plooj (porcelain) feem ntau dais siab, thiab lub caj dab ntawm cov plooj (porcelain) yog nyias, uas tseem yog thaj chaw uas siv hluav taws xob muaj zog. Thaum muaj micro pores thiab lwm yam tsis xws luag nyob rau hauv lub caj dab ntawm cov plooj (porcelain) qhov chaw, los yog cov kab nrib pleb tshwm nyob rau hauv lub lag luam, nws yog ib qhov ua tau los rhuav tshem cov plooj (porcelain) qhov chaw thiab tsim tsis muaj nqi insulators. Yog li ntawd, hom insulator no yog ib qho tawg hom insulator. Cov iav qhov chaw, lub kaus mom hlau thiab steel taw ntawm tempered iav insulators yog ntsia nrog qib siab cement los ua lub hau taw hom disk ncua kev kawm tempered iav insulators. Nws cov qauv thiab cov duab yog ze heev rau cov porcelain insulator. Thaum lub iav qhov chaw hauv kev ua haujlwm tsis zoo vim qhov kev ua tiav ntawm kev siv lub sijhawm ntev thiab lub zog hluav taws xob, lub kaus disc ntawm tempered iav lub cev yuav tawg, uas yog, "tus kheej tawg". Qhov zoo tshaj plaws feature ntawm toughened iav insulator yog nws yuav nws tus kheej tawg thaum muaj inferior insulators nyob rau hauv toughened iav insulator, uas tshem tawm cov txheej txheem nyuaj uas insulators yuav tsum tau kuaj ib tug los ntawm ib tug. Sab nrauv ntawm lub insulator yog ua los ntawm cov khoom siv silicon roj hmab core pas nrig, uas yog tsim los ntawm epoxy resin, thiab sab nraud ntawm lub insulator yog txuas nrog lub kaus core pas nrig. Cov tub ntxhais pas nrig yog tsim los ntawm epoxy resin, thiab sab nraud ntawm lub insulator yog tsim rau hauv ib lub kaus sib xyaw. Cov hom kev sib txuas ntawm mandrel thiab qhov kawg fittings feem ntau suav nrog sab nrauv wedge, sab hauv wedge type, sab hauv thiab sab nrauv wedge ua ke, mandrel rib kua nplaum hom thiab crimping hom. Vim nws cov cuab yeej tsim khoom yooj yim thiab cov txheej txheem tsim khoom, qhov zoo ntawm cov khoom siv hluav taws xob sib xyaw yog lub teeb, thiab txhua yam yooj yim rau kev khiav lag luam, uas yog nyiam heev los ntawm lub hwj chim department.
Yog li ntawd, iav insulator, ceramic insulator thiab composite insulator muaj lawv tus kheej zoo thiab qhov tsis zoo. Nyob rau hauv cov txheej txheem installation, nws kuj yog nyob ntawm tus tsim cov kev xav tau ntawm cov kab tshwj xeeb kom pom qhov twg tsim nyog dua
