1. Kev puas tsuaj
Cable tsis ua hauj lwm tshwm sim los ntawm cov neeg kho tshuab kev puas tsuaj account rau ib tug loj feem ntawm cable xwm txheej. Lub cable puas thaum lub sij hawm installation. Cov neeg kho tshuab traction ntau dhau yuav ua rau lub cable thiab ntau dhau kev khoov yuav ua rau lub cable puas; Kev puas tsuaj ncaj qha los ntawm kev quab yuam sab nraud thiab kev puas tsuaj los ntawm ntuj tshwm sim (xws li lub tsheb dov, ntog pob zeb, ib puag ncig corrosion, thiab lwm yam) yog ib qho yooj yim ua rau lub cev tsis ua haujlwm cable.
2. Kev rwb thaiv tsev ntub dej
Qhov laj thawj tseem ceeb yog tias cov cuab yeej siv hluav taws xob nruab nrab ntawm qhov txuas nruab nrab thiab lub davhlau ya nyob twg txuas tsis zoo, uas ua rau kev sib khi tsis ua haujlwm, kev nkag mus rau cov dej noo thiab rwb thaiv tsev puas.
3. rwb thaiv tsev deterioration
Qhov sib txawv ntawm huab cua sab hauv ntawm lub cable rwb thaiv tsev nruab nrab yog tso tawm nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, yog li txo cov rwb thaiv tsev; Overheating kuj tuaj yeem ua rau lub rwb thaiv tsev tsis zoo thiab ua rau txo qis hauv rwb thaiv tsev.
4. Tshaj dhau
Kev cuam tshuam ntawm over-voltage, switching over-voltage and fault transient over-voltage will make cable insulation layer to break and form faults.
5. Kev tsim thiab kev tsim khoom tsis zoo
Cov dej tsis zoo ntawm cov pob qij txha nruab nrab thiab cov pob qij txha hauv lub davhlau ya nyob twg, cov khoom siv hluav taws xob tsis zoo, cov khoom siv tsis zoo, cov txheej txheem tsim khoom tsis zoo, thiab tsis ua raws li cov cai ntawm kev khiav hauj lwm yuav ua rau lub taub hau hluav taws xob tsis ua haujlwm.
6. Cov teeb meem loj
Cov khoom siv insulating ntawm lub cable nws tus kheej yog qhov tsis zoo; Nyob rau hauv cov txheej txheem ntawm wrapping txheej insulating, tsis xws luag xws li wrinkles, kab nrib pleb, kab nrib pleb thiab overlapping gaps yuav tshwm sim nyob rau hauv lub insulating txheej. Qhov tsis xws luag hauv kev tsim cov khoom siv cable sib koom ua ke, kev tsis sib haum xeeb lossis kev tsis sib haum thaum sib dhos; Kev saib xyuas tsis zoo thiab kev tswj xyuas cov ntaub ntawv insulating ua rau cov dej noo, plua plav thiab kev laus ntawm cov rwb thaiv tsev cable.
