Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub thawv sib txuas yog yooj yim: nws siv cov khoom sib txuas los txuas ntau cov cables lossis cov xov hlau ua ke. Feem ntau, cov qauv sab hauv ntawm lub thawv sib txuas siv cov khoom sib txuas tshwj xeeb xws li insulators, terminals, thiab kho cov ntsia hlau kom muaj kev ruaj ntseg thiab txhim khu kev qha.
Cov thawv sib txuas yog siv dav hauv cov tshuab fais fab. Piv txwv li, nyob rau hauv cov kab sib txuas thiab substations, ntau lub thawv sib txuas yog siv rau cable lossis hlau pob qij txha thiab ceg. Tsis tas li ntawd, nyob rau hauv cov xwm txheej tshwj xeeb, xws li kev sib txuas siab -voltage cables lossis xa cov yees, cov thawv sib txuas kuj tau siv rau kev sib txuas hluav taws xob.
Nyob rau hauv luv luv, raws li ib tug tseem ceeb heev hluav taws xob kev twb kev txuas ntaus ntawv, lub hlws ris lub thawv pab peb txuas thiab ceg circuits, tiv thaiv kev ua hauj lwm ntawm cov khoom siv hluav taws xob, thiab txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm lub hwj chim system.
