Kev them nyiaj yug insulators yog ib yam tshwj xeeb ntawm kev tiv thaiv rwb thaiv tsev uas ua lub luag haujlwm tseem ceeb hauv cov kab hluav taws xob hluav taws xob. Yav dhau los, kev txhawb nqa insulators feem ntau yog siv rau ntawm cov ncej fais fab thiab maj mam tsim los dai ntau cov insulators raug tshem tawm ntawm ib kawg ntawm cov kab hluav taws xob siab txuas ntxiv txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Lawv feem ntau yog ua los ntawm silicone roj hmab lossis porcelain thiab hu ua insulators. Insulators ua si ob lub luag haujlwm tseem ceeb hauv cov kab hluav taws xob siv hluav taws xob, uas txhawb nqa cov kab hluav taws xob thiab tiv thaiv tam sim no los ntawm ntws rov qab mus rau hauv av. Ob lub ntsiab lus tseem ceeb no yuav tsum tau lav. Insulators yuav tsum tsis txhob ua yuam kev luv luv vim yog kev hloov pauv ntawm ib puag ncig thiab cov khoom siv hluav taws xob, txwv tsis pub cov insulators yuav poob lawv cov txiaj ntsig thiab ua rau muaj kev puas tsuaj rau kev siv thiab kev ua haujlwm ntawm cov kab xa tawm.
Muaj ntau lub disc-hom insulators yog dai rau ntawm qhov kawg ntawm high voltage kab kev twb kev txuas ntauwd kom lub creepage nrug. Lawv feem ntau yog ua los ntawm laminated iav, porcelain, los yog yas thiab hu ua insulators. Txhawm rau tiv thaiv cov av thiab lwm yam kab mob los ntawm adhering rau saum npoo ntawm lub insulator thiab ua rau luv luv-circuit faults los ntawm lub insulator, uas yog hu ua creepage. Yog li ntawd, qhov sib nrug ntawm qhov chaw, uas yog, qhov deb ntawm qhov nkag, yog nce, uas yog qhov kev ncua deb ntawm kev them nyiaj thiab tso tawm raws li qhov chaw insulator. Creepage nrug=nto qhov sib nrug / system software siab voltage. Nyob ntawm seb muaj pes tsawg tus kab mob sib kis, thaj chaw uas muaj av hnyav feem ntau siv qhov deb ntawm 31mm / ib KV. Ib qho xoom-tus nqi insulator yog hais txog ib qho insulator uas nws muaj peev xwm faib ntawm ob qhov kawg yog ze rau xoom lossis sib npaug rau xoom thaum lub sijhawm ua haujlwm.
Qhov cuam tshuam ntawm xoom-tus nqi lossis tus nqi qis qis: cov rwb thaiv tsev ntawm cov kab hluav taws xob xaim hluav taws xob nyob ntawm cov insulator, vim yog cov khoom tsis xws luag lossis lwm yam cuam tshuam xws li cov khoom siv hluav taws xob tsis zoo lossis hluav taws xob. Cov yam ntxwv ntawm lub rwb thaiv tsev ntawm lub insulator yuav deteriorate tsis tu ncua. Thaum cov rwb thaiv tsev tiv thaiv txo qis los yog xoom, nws yog hu ua tus nqi qis qis lossis xoom-tus nqi insulator. Insulators yog du thiab tuaj yeem txo cov nyhuv capacitive ntawm cov kab cable, yog li txo qhov poob tam sim no.
