Qhov zoo ntawm iav insulators:
Vim lub siab mechanical zog ntawm qhov chaw ntawm lub iav insulator, qhov saum npoo yog tsis yooj yim rau tawg.Lub zog hluav taws xob ntawm iav feem ntau tseem tsis hloov pauv thaum lub sijhawm ua haujlwm tag nrho, thiab nws cov txheej txheem kev laus qeeb qeeb dua li cov plooj (porcelain).Yog li ntawd, cov iav insulators feem ntau yog muab pov tseg vim kev puas tsuaj rau tus kheej, uas tshwm sim nyob rau hauv thawj xyoo ntawm kev ua haujlwm, tab sis qhov tsis zoo ntawm cov plooj (porcelain insulators) tsuas yog ua haujlwm rau ob peb xyoos xwb tom qab pib nrhiav pom.
Kev siv cov iav insulators tuaj yeem tshem tawm qhov kev tiv thaiv tsis tu ncua ntawm cov insulators thaum ua haujlwm.Qhov no yog vim tias txhua yam kev puas tsuaj rau cov iav tempered yuav ua rau kev puas tsuaj ntawm cov insulator, uas yog ib qho yooj yim rau cov neeg ua haujlwm nrhiav tau thaum saib xyuas cov kab.Thaum lub insulator puas lawm, cov iav tawg nyob ze ntawm lub hau steel thiab hlau taw yog daig, thiab cov neeg kho tshuab lub zog ntawm cov seem ntawm cov insulator yog txaus los tiv thaiv lub insulator los ntawm tawg.Tus kheej-tawg tus nqi ntawm cov iav insulators yog ib qho tseem ceeb ntsuas los ntsuas cov khoom zoo, thiab nws tseem yog lub hauv paus zoo rau kev ntsuam xyuas kev sib tw hauv qhov kev sib tw tam sim no thiab kev sib tw.
