Lub txee hloov pauv yog ib qho khoom siv hluav taws xob uas cov kab hluav taws xob sab nraud ua ntej nkag mus rau qhov hloov pauv tseem ceeb hauv lub txee, tom qab ntawd mus rau ceg tswj cov keyboards, txhua qhov teeb tsa raws li nws xav tau. Nws muaj cov cuab yeej siv, kev tswj tsis siv neeg, lub cev muaj zog sib nqus, ntau yam AC contactors, thiab lwm yam. Qee qhov hloov khoom siv kuj muaj siab -voltage thiab low-voltage compartments, thiab high-voltage busbars, xws li hauv cov chaw fais fab. Qee qhov kuj tseem muaj cov khoom siv qis qis los tiv thaiv cov cuab yeej tseem ceeb.
Lub luag haujlwm tseem ceeb ntawm lub txee hloov pauv yog qhib, kaw, tswj, thiab tiv thaiv cov khoom siv hluav taws xob thaum lub sijhawm tsim hluav taws xob, xa tawm, xa tawm, thiab cov txheej txheem hloov hluav taws xob hauv lub zog hluav taws xob. Cov khoom tseem ceeb hauv lub txee hloov pauv muaj xws li cov hluav taws xob hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov cuab yeej siv hluav taws xob, thiab ntau yam khoom siv tiv thaiv. Hloov cov txee tuaj yeem muab faib ua ntau txoj hauv kev, xws li los ntawm kev teeb tsa kev teeb tsa hluav taws xob (tshem tawm cov khoom hloov pauv thiab cov khoom hloov ruaj khov); los yog los ntawm cov qauv txee (qhib cov txee hloov, hlau- kaw cov txee hloov, thiab hlau- kaw cov khoom siv armored); thiab los ntawm qib voltage (high-voltage hloov txee, nruab nrab-voltage hloov txee, thiab qis-voltage hloov txee). Nws yog qhov tsim nyog rau ntau lub sijhawm xws li cov chaw tsim hluav taws xob, cov chaw tsim hluav taws xob, cov nroj tsuag petrochemical, metallurgical steel dov mills, lub teeb kev lag luam thiab textiles, factories thiab mines, cov zej zog, thiab cov tsev siab - nce siab.
