Raws li qhov tseem ceeb ntawm cov rwb thaiv tsev sab nraud ntawm lub zog hluav taws xob, cov porcelain insulators ncaj qha cuam tshuam rau kev nyab xeeb thiab txhim khu kev lag luam ntawm daim phiaj hluav taws xob, thiab yuav tsum ua kom tau raws li cov kev xav tau nruj hauv hluav taws xob, tshuab, thiab ib puag ncig. Cov khoom siv rwb thaiv tsev yog sib npaug rau "cov pob qij txha" ntawm ultra-high voltage (UHV) thiab ntxiv -high voltage (EHV) kis kab; lawv qhov kev ua tau zoo cuam tshuam ncaj qha rau qhov ua tau thiab kev ntseeg tau ntawm UHV thiab EHV kis tau tus mob thiab hloov pauv thev naus laus zis.
Nyob rau hauv cov nqe lus ntawm hluav taws xob kev ua tau zoo, porcelain insulators yuav tsum muaj lub zog rwb thaiv tsev siab. Rau UHV daim ntawv thov, lawv yuav tsum muaj peev xwm tiv taus kev khiav hauj lwm voltages siab tshaj 1000kV thiab xob laim impulse voltages tshaj 3000kV. Lawv qhov chaw feem ntau yog tsim los nrog cov qauv awning kom nce qhov kev ncua deb, nrog rau tus qauv creepage nrug ntawm 20-35mm / kV.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo txhua yam, porcelain insulators yuav tsum muaj lub zog txhua yam los txhawb qhov hnyav ntawm cov khoom siv thiab cov khoom siv thiab tiv taus ntau yam kev ntxhov siab thaum ua haujlwm. UHV porcelain insulators yuav tsum muaj peev xwm tiv taus txhua yam kev ntxhov siab xws li khoov, torsion, nro, thiab compression. Kab porcelain insulators tuaj yeem tiv taus cov khoom siv hluav taws xob ntawm 80-160kN.
Nyob rau hauv cov nqe lus ntawm ib puag ncig adaptability, porcelain insulators yuav tsum tiv thaiv complex thiab hnyav sab nraum zoov ib puag ncig rau ncua sij hawm, xws li cua, daus, nag, xob laim, ultraviolet hluav taws xob, thiab muaj kuab paug. Lawv qhov ntsuas kub ua haujlwm feem ntau yog -60℃rau +80℃.
Cov ntaub ntawv thiab cov qauv tsim ntawm cov porcelain insulators yuav tsum ua tau raws li cov cai no. Cov khoom siv plooj (porcelain) feem ntau yog siv lub siab -lub zog aluminium- raws li cov qauv plooj (porcelain formula) kom paub meej cov khoom zoo thiab kev ntseeg siab. Cov pa phem-cov insulators tiv taus feem ntau siv qhib- hom hloov pauv- qhov loj me los yog ribbed alternating-size sheds nyob rau hauv lub sheds los txhim kho cov yam ntxwv paug thiab txhim khu cov ntub flashover thiab muaj kuab paug tiv thaiv. Cov pob qij txha txuas ntawm cov khoom siv plooj (porcelain) thiab cov khoom siv hlau feem ntau siv cov xuab zeb cylindrical -coated qauv nrog granulated xuab zeb tshwj xeeb los txhim kho kev sib raug zoo thiab kev siv zog. Hlau fittings xws li flanges siv siab- cov ntaub ntawv muaj zog (piv txwv li, cov hlau nplaum) thiab tau txais kev tiv thaiv kev tiv thaiv corrosion (xws li, kub-dip galvanizing).
Txhawm rau kom ntseeg tau, txhua yam khoom yuav tsum raug kuaj xyuas, kuaj ultrasonic, thiab plaub -txoj kev bending load kuaj. Cov txheej txheem kev ntsuas hluav taws xob ib txwm siv, xws li cov txheej txheem me me tso tawm, infrared thermal imaging txoj kev, thiab txoj kev kuaj pom tam sim no, muaj qee yam kev txwv. Novel tsis yog-tshuaj ntsuam xyuas kev puas tsuaj, xws li kev vibration acoustic test, tuaj yeem siv rau kev tshuaj xyuas cov khoom siv hluav taws xob tom qab.
