Hloov txee yog cov khoom siv hluav taws xob. Cov kab sab nraud ntawm lub txee hloov nkag mus rau qhov hloov pauv tseem ceeb hauv lub txee ua ntej, thiab tom qab ntawd nkag mus rau qhov hloov pauv hloov. Txhua ceg yog teem raws li nws xav tau. Piv txwv li, cov twj paj nruag, kev tswj tsis siv neeg, lub cev muaj zog sib nqus keyboards, ntau yam AC contactors, thiab lwm yam., qee qhov kuj tau nruab nrog high-voltage thiab low-voltage chav hloov khoom, cov tsheb npav siab, xws li fais fab nroj tsuag, thiab lwm yam, thiab qee qhov yog kuj nruab nrog lub voj voog qis load shedding rau cov khoom tseem ceeb. Lub luag haujlwm tseem ceeb ntawm kev hloov iav yog hloov mus rau thiab tawm, tswj thiab tiv thaiv cov khoom siv hluav taws xob hauv cov txheej txheem ntawm kev tsim hluav taws xob, kev xa tawm, kev faib tawm thiab kev hloov hluav taws xob hauv lub zog hluav taws xob. Cov khoom nyob rau hauv lub txee hloov yog tsuas yog tsim los ntawm Circuit Court breakers, disconnectors, load keyboards, kev khiav hauj lwm mechanisms, kev sib nrig sib inductors thiab tiv thaiv cov khoom ntawm rwb thaiv tsev. Ntawm lawv, lub luag haujlwm ntawm cov khoom siv rwb thaiv tsev yog kev txhawb nqa, kev thauj khoom, kev sib cais thiab lwm yam kev xav tau, yog li cov kev cai ntawm cov ntaub ntawv rwb thaiv tsev yog: siab dua hluav taws xob, siab dua mechanical zog, ntau arc kuj, thiab lwm yam.
