Cov txheej txheej rwb thaiv tsev ntawm lub zog hluav taws xob yog tsim ntawm ntau cov khoom sib txawv xws li ntawv, roj, hemp, roj hmab, yas, asphalt, thiab lwm yam. Yog li ntawd, cov cable muaj qhov ua tau ntawm qhov hluav taws thiab tawg. Cov laj thawj rau hluav taws thiab tawg ntawm lub cable yog:
(1) Luv-luv tsis ua haujlwm los ntawm kev puas tsuaj rwb thaiv tsev. Cov ntawv txhuas tiv thaiv ntawm lub hwj chim cable raug puas ntsoog thaum nteg lossis lub rwb thaiv tsev cable yog mechanically puas thaum ua haujlwm, uas ua rau cov hluav taws xob tawg ntawm cov xaim lossis nruab nrab ntawm cov ntawv txhuas, thiab cov arc ua rau cov khoom siv rwb thaiv tsev thiab cov txheej tiv thaiv sab nrauv ntawm rau cable rau hlawv thiab taws.
(2) Lub sijhawm ntev ua haujlwm dhau ntawm txoj haujlwm cable. Lub sijhawm ua haujlwm ntev dhau ntawm kev ua haujlwm, kev ua haujlwm kub ntawm lub cable rwb thaiv tsev cov khoom ntau tshaj qhov ntsuas kub tshaj plaws ntawm cov cua kub li qub, thiab lub rwb thaiv tsev ntawm lub cable muaj hnub nyoog thiab qhuav. Qhov tshwm sim ntawm rwb thaiv tsev laus thiab ziab yog feem ntau tshwm sim rau tag nrho cov kab cable. Vim tias qhov kev laus thiab qhov tsis zoo ntawm lub rwb thaiv tsev cable, cov khoom siv rwb thaiv tsev poob lossis txo qhov rwb thaiv tsev thiab cov khoom siv, yog li nws nquag tua thiab kub hnyiab, thiab tseem kub hnyiab thiab tua hluav taws ntawm ntau qhov chaw raws tag nrho ntev ntawm lub cable.
(3) Cov roj tso rau hauv cov roj txuas nrog kua los yog dej tawm vim qhov txawv ntawm qhov siab. Thaum cov roj-immersed cable tso nrog lub qhov siab sib txawv loj, lub cable tuaj yeem nqus roj. Raws li qhov tshwm sim ntawm qhov txaus, qhov qaum ntawm lub cable dries vim poob cov roj. Lub tshav kub tsis kam ntawm cov ntu ntawm lub cable nce, ua rau daim ntawv rwb thaiv tsev yuav hlawv thiab tawg ua ntej. Tsis tas li, vim tias cov roj ntawm lub sab qaum ntws ntws mus rau hauv qab, qhov chaw tsim nyob rau ntawm lub taub hau cable sab saum toj thiab lub siab tsis zoo yog tsim tawm, uas ua rau lub cable yooj yim kom nqus noo thiab ua kom kawg ntub. Vim tias lub tsub zuj zuj ntawm cov roj, qhov qis qis dua ntawm txoj kab hluav taws xob ua rau ntau lub siab zoo li qub, uas txhawb nqa cov roj to ntawm lub taub hau cable. Noo noo thiab roj to ntawm lub cable ntxiv qhov tshwm sim ntawm qhov ua tsis tiav thiab qhov hluav taws kub.
(4) Rwb thaiv tsev rhuav tshem cov thawv nruab nrab. Qhov nruab nrab ntawm qhov txuas ntawm lub thawv ob leeg tsis txuas ntom ntom, txuas ruaj khov, lossis cov khoom sib txuas tsis tau xaiv zoo, qhov kev sib koom tes yog oxidized, ua kom sov, thiab txhaws thaum lub sijhawm ua haujlwm; thaum cable nruab nrab sib koom ua kom zoo, qhov zoo ntawm tus neeg sawv cev insulating nchuav mus rau hauv nruab nrab lub thawv sib koom ua ke tsis tau raws li qhov yuav tsum tau ua thaum lub tshuab hluav taws xob insulating, muaj pores hauv lub thawv thiab lub thawv cable tsis zoo, puas, thiab noo noo los. Cov xwm txheej saum toj no tuaj yeem ua rau rwb thaiv tsev tawg, tsim kho lub voj voog luv, thiab ua rau lub cable tawg thiab ntes hluav taws. Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob Network
(5) rau hauv lub taub hau cable. Vim tias qhov saum npoo ntawm lub cable lub taub hau yog ntxooj thiab muaj kuab paug, lub tsho me me ntawm lub taub hau cable tau tawg thiab cov hlau txhuas me me heev, uas ua rau flashover thiab hluav taws, ua rau lub nplaim hluav taws xob ntawm lub cable lub taub hau thiab cov hlau hluav taws xob rwb thaiv tsev kom hlawv Cov.
(6) Cov qhov hluav taws kub sab nraud thiab sab nraud ua rau hluav taws xob cable. Piv txwv li, kev sib kis ntawm cov roj system hluav taws, kis ntawm roj Circuit Court breaker tawg hluav taws, qhov sib xws ntawm cov nplaim hluav taws xob hauv cov kab hluav taws xob (boiler pulverizing system) lossis cov roj zeb xa hluav taws xob, cov ci ntawm cov pa roj hluav taws kub ntau, cov tshuaj tiv thaiv corrosion ntawm cov kua qaub thiab alkali, hluav taws xob vuam vaim thiab lwm hom hluav taws tuaj yeem ua rau lub cable Tsim hluav taws.
