Qhov zoo ntawm iav insulators

Hauv thawj ob peb xyoos ntawm kev tsim khoom thiab kev ua haujlwm, iav insulators tau pom tias muaj cov txiaj ntsig zoo ntawm cov plooj (porcelain insulators):
Vim lub siab mechanical zog ntawm txheej txheej ntawm iav insulators, cov kab nrib pleb tsis tshua muaj tshwm sim ntawm qhov chaw. Lub zog hluav taws xob ntawm iav feem ntau tseem tsis hloov pauv txhua lub sijhawm ua haujlwm, thiab nws cov txheej txheem kev laus qeeb qeeb dua li cov plooj (porcelain). Yog li ntawd, iav insulators feem ntau yog muab pov tseg vim kev puas tsuaj rau tus kheej thiab tshwm sim hauv thawj xyoo ntawm kev ua haujlwm. Txawm li cas los xij, qhov tsis xws luag hauv cov plooj (porcelain insulators) tsuas yog pib pom tom qab ob peb xyoos ntawm kev ua haujlwm.
Los ntawm kev siv iav insulators, kev tiv thaiv tsis tu ncua ntawm cov insulators thaum lub sijhawm ua haujlwm tuaj yeem raug tshem tawm. Qhov no yog vim tias txhua yam kev puas tsuaj rau cov iav tempered tuaj yeem ua rau muaj kev puas tsuaj rau lub rwb thaiv tsev, thiab cov neeg ua haujlwm tuaj yeem pom nws yooj yim thaum kuaj kab. Thaum lub insulator puas lawm, cov iav tawg nyob ze ntawm lub hau steel thiab hlau ko taw yog daig, thiab cov neeg kho tshuab lub zog ntawm cov seem ntawm cov insulator yog txaus los tiv thaiv txoj hlua insulator los ntawm kev tawg. Tus kheej rupture tus nqi ntawm cov iav insulators yog ib qho ntawm cov cim tseem ceeb los ntsuas cov khoom zoo, thiab nws tseem yog lub hauv paus zoo rau kev ntsuam xyuas hauv kev sib kis tam sim no engineering kev sib tw thiab kev sib tw.
