Tom qab ua tiav ntawm qhov kev teeb tsa, kev tshuaj xyuas kev lees paub zoo yuav tsum tau ua. Ua ntej, xyuas kom meej tias sab nrauv ntawm qhov qis -voltage switchgear los ua ke tsis zoo thiab tsis muaj kev puas tsuaj, tsis muaj cov cim qhia ntawm deformation lossis kev puas tsuaj rau lub cev. Qhov thib ob, tshuaj xyuas cov kev sib txuas hluav taws xob kom ntseeg tau tias lawv muaj kev nyab xeeb thiab txhim khu kev qha, tsis muaj kev xoob lossis cov cim qhia ntawm overheating. Tib lub sijhawm, cov cuab yeej ntsuas tsim nyog yuav tsum tau siv los ua cov kev ntsuas hluav taws xob ua haujlwm ntawm lub switchgear, yog li ua kom muaj kev ua raws li cov qauv tsim thiab cov qauv tsim.
Lub txee lub cev tsis muaj deformation, khawb, xim chipping, lossis corrosion; cov xim yog uniform, thiab cov cim yog meej.
Lub txee lub cev yog ruaj ntseg bolted rau nws lub hauv paus, thiab grounding yog txhim khu kev qha; grounding kuj tsawg dua los yog sib npaug rau 4Ω.
Tag nrho cov kev sib txuas ntawm cov kab hluav taws xob muaj kev ruaj ntseg; txhua lub davhlau ya nyob twg tsuas yog ib tus neeg xyuas pib (nrog rau kev zam rau ob); conductors dhau los ntawm cov khoom siv hlau yuav tsum tau tiv thaiv.
Lub Hoobkas daim ntawv pov thawj ntawm kev ua tau zoo, cov ntawv xeem, cov duab kos, thiab cov ntawv ua haujlwm tiav.
