Cov tsos ntawm cov kua nruab nrab ntawm insulator tuaj yeem ncaj qha mus saib tus kab insulator puas yog. Hauv kev kuaj xyuas pom kev, cov ntaub ntawm cov kua tshuaj insulator thiab cov ntaub qhwv thiab cov nplaum raug kuaj xyuas. Qhov kev laus ntawm lub sij hawm soj ntsuam thiab kev txhuam ntawm qhov kawg yog raws li nram no. Nyob rau hauv cov ntaub ntawv, lub insulator yog ib tug ncaj qha seem khoom.
1 Cov hluav taws xob yog catalyzed los ntawm corrosion thiab ruptured.
2 Cov khoom siv hluav taws xob lossis hluav taws xob tshwm tuaj rau hauv cov ntaub thaiv thiab lub qhov ncauj, thiab tag nrho nws ntev npaum li cas yog ntau tshaj li ib feem kaum ntawm tus kabmob dej ntawm qhov insulator los yog qhov tob hauv qhov siab tshaj 30% ntawm cov khoom txheej ntawm qhov chaw tsim.
3 Degumming sealant tsis ua hauj lwm tshwm sim.
4 dej tshuaj qis dua.
