Khoom Taw Qhia:
Composite post insulators tuaj yeem siv txoj hauv kev nqaim kom qhib qhov hluav taws xob thiab xa hluav taws xob. Lawv tsim nyog rau kev hloov pauv hauv nroog network, tuaj yeem txo qhov siab ntawm tus ncej, thiab tuaj yeem txuag tau ntau tus neeg ua haujlwm, khoom siv thiab nyiaj txiag. Vim tias lawv lub zog khoov siab, lawv tuaj yeem tiv thaiv cov plooj (porcelain cross) - caj npab los ntawm qhov tshwm sim yooj yim Qhov kev sib tsoo cascade yog ib yam khoom uas tsis tuaj yeem hloov los ntawm porcelain cross- caj npab; Nws yog qhov me me, lub teeb hauv qhov hnyav, muaj zog hauv kev poob siab thiab kev cuam tshuam, thiab tsis tas yuav tsum tau ntxuav phau ntawv, muab kev lees paub rau kev ua haujlwm nyab xeeb. Cov khoom no txais yuav tus pas nrig tag nrho tsim, compact qauv, zoo, thiab qhov hnyav yog 1/10 ntawm tib theem ntawm porcelain thiab iav insulators. Nws yooj yim heev rau kev thauj thiab nruab.
Haum rau qhov chaw qias neeg, siab mechanical tensile loads, loj spans thiab compact kab. Pollution flashover voltage yog 30%-50% siab dua li cov plooj (porcelain) thiab iav insulators ntawm tib theem. Kev ua tau zoo yog ruaj khov nyob rau hauv qhov kub thiab txias ntawm -60 degrees - +200 degrees; qhov kev tsim tsis tawg yog tau txais, thiab tsis tas yuav ntsuas tus nqi xoom thaum lub sijhawm ua haujlwm. Superior hluav taws xob kev ua tau zoo thiab siab mechanical zog. Lub tensile thiab flexural lub zog ntawm epoxy iav txhuas rods nqa sab hauv yog 2 zaug siab dua li cov hlau zoo tib yam, thiab 8 ~ 10 npaug ntawm cov ntaub ntawv muaj zog porcelain, uas zoo txhim kho kev ntseeg siab ntawm kev ua haujlwm nyab xeeb.
Kev ua qias tuaj zoo, zoo tiv thaiv - kev ua qias tuaj, muaj zog tiv thaiv - pa phem flashover lub zog, nws ntub dej tiv taus hluav taws xob thiab muaj kuab paug tiv thaiv hluav taws xob yog 2 ~ 2.5 npaug ntawm cov plooj (porcelain insulators) nrog tib qhov kev nkag mus deb. Thiab nws tsis tas yuav tsum tau ntxuav, thiab nws tuaj yeem khiav nyab xeeb hauv qhov chaw muaj kuab paug hnyav.
