Qhov sib xyaw ncej insulator yog tsim los ntawm ib lub mandrel, lub kaus daim tiab thiab ib qho kev sib txuas. Cov tub ntxhais pas nrig yog ua los ntawm fiberglass steel, uas yog siv los muab cov khoom siv hluav taws xob ntawm cov insulator. Lub sheath txuas nrog rau saum npoo ntawm cov tub ntxhais pas nrig los ntawm cov nplaum, uas ua lub luag haujlwm ntawm kev tiv thaiv cov tub ntxhais qws. Cov khoom sib txuas yog nyob rau ntawm ob qho kawg ntawm cov pillar insulator, uas plays lub luag hauj lwm ntawm kev sib txuas cov pillar insulator nrog tus ncej thiab ntauwd kho vajtse.
Qhov kawg kev twb kev txuas hom ntawm composite ncej insulator yuav muab faib ua wedge hom thiab crimping hom. Wedge hom tuaj yeem muab faib ua hom kab npoo sab nrauv thiab sab hauv wedge hom.
Cov cuab yeej tsim khoom ntawm insulator kaus tiab thiab mandrel tuaj yeem muab faib ua lub kaus extruded thiab ib qho kev txhaj tshuaj. Lub kaus extruded yog los nplaum lub kaus tiab rau mandrel, yog li muaj ob qhov sib txuas: mandrel - sheath thiab sheathing - kaus npog. Lub kaus daim tiab thiab mandrel sheath yog tsim nyob rau hauv ib lub cev nyob rau hauv lub integral txhaj hom, thiab tsuas yog lub mandrel - sheath interface yog muaj.
Qhov tsis ua hauj lwm ntawm cov khoom siv hluav taws xob muaj xws li flashover, mechanical zog poob, mandrel breakdown, brittle so, mandrel crisp rot, sab nraud puas tsuaj, thiab lwm yam. Ntawm lawv, sab nraud quab yuam kev puas tsuaj yog muaj feem xyuam rau lub sab nraud ib puag ncig tswj, thiab lwm yam mas yog nyob ntawm tus insulator tus kheej lub xeev, uas yog ze ze rau kev laus.
Tam sim no, cov ncej hluav taws xob sib txuas feem ntau siv cov qauv kev sib txuas ntawm crimping, thiab cov ncej sib txuas ntawm cov qauv no yuav luag tsis muaj qhov tshwm sim ntawm kev tawg txoj hlua ntawm lub insulator vim qhov txo qis ntawm cov khoom siv hluav taws xob. Nyob rau hauv cov ntaub ntawv ntawm acid-resistant mandrel, lub composite post insulator yuav luag tsis ua brittle breakage.
Yog li ntawd, tam sim no, tsis ua hauj lwm ntawm cov pillar insulators muaj feem xyuam rau kev laus feem ntau suav nrog mandrel tawg thiab nkig tawg. Txij li thaum txo qis hydrophobicity kuj tuaj yeem ua rau paug thiab puas tsuaj rau lub mandrel, txo hydrophobicity kuj suav tias yog ib hom kev tsis ua haujlwm nrog kev laus.
