Cov pillar insulator yog tsim los ntawm mandrel, kaus tiab sheath (bonding txheej) thiab txuas fittings. Lub mandrel thiab hlau kawg muaj zog tensile thiab dabtsi yog khoov lub zog, thiab lub kaus lub tais ua los ntawm cov ntaub ntawv organic muaj zoo hydrophobicity thiab anti-fouling flashover muaj peev xwm. Nws yog tsim rau high voltage kis kab, tshwj xeeb tshaj yog rau cov chaw qias neeg, thiab muaj peev xwm tiv thaiv kom txhob muaj kuab paug flashover xwm txheej. Thaum cov kab hluav taws xob thiab kev puas tsuaj yog tib yam, qhov hnyav ntawm cov pas nrig sib txuas pillar insulator tsuas yog 1/6 txog 1/10 ntawm cov hlua khi hlua khi, thiab nws yooj yim rau nruab thiab hloov.
Cov txiaj ntsig zoo no ua rau nws hloov cov khoom lag luam rau cov plooj (porcelain insulators) dav siv tam sim no. Qws composite post insulators muaj lub zog tshwj xeeb (lub zog tensile rau huab hwm coj piv) thiab cov yam ntxwv zoo heev los tiv thaiv fouling flashover, tab sis muaj peev xwm ntawm kev cuam tshuam hauv kev sib tshuam thiab mand-rod brittle so, thiab kev pab cuam lub neej ntawm cov khoom siv organic thiab ntev. -term kev ntseeg siab ntawm qhov kawg kev sib txuas cheeb tsam tsis tau pom zoo.
Lub mandrel yog fiberglass bar tsim los ntawm resin bonding lab ntawm iav fibers thaum uas tig mus rau axis. Lub zog tensile yog siab dua 600MPa, 3 mus rau 5 npaug ntawm lub zog siab porcelain, sib npaug rau cov pa roj carbon zoo, nrog kev ua haujlwm zoo thiab qaug zog, tiv taus cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob, thiab yog qhov tseem ceeb ntawm sab hauv. rwb thaiv tsev. Reinforcement fibers thiab resins nrog me me creep yog xaiv. Xyuas kom meej tias lub mandrel muaj cov khoom zoo thiab cov khoom siv hluav taws xob.
