Ukukhetha uluhlu lwesicelo solawulo lombane oluchanekileyo lunokwenza ukuba ludlale indima enkulu. Oku kulandelayo yeminye yemimandla yesicelo sayo. Uluhlu losetyenziso lwamanqanaba amathathu olawulo lwamandla ombane lubanzi kakhulu, kwaye lusasazwe kwiindawo ezinkulu ezifana nezothutho, iposi kunye nonxibelelwano, unomathotholo nomabonwakude, kunye neenkqubo zekhompyuter.
Ukongeza, kwezinye iindawo ezifuna ukuchaneka kwedatha ephezulu, njengokubumba isitofu senkqubo yekhompyuter, izixhobo zoomatshini be-CNC, iimotor ezahlukeneyo zombane kunye nezinye izixhobo, kunye nezixhobo zonyango ezithunyelwa kwamanye amazwe (ezifana noomatshini beCT) kunye nezinyusi ezahlukeneyo ezixhasa iimodeli ezizodwa, kwakhona Inokusetyenziswa, kwaye indima yayo ikhonza imveliso yabantu.

Enyanisweni, uluhlu lwesicelo lwayo lubanzi kakhulu xa kuthelekiswa nezinye iintlobo zolawulo lombane. Njengoko iindlela zokuvelisa ziphucula, kukholelwa ukuba ziya kuba nezicelo ezibanzi.
I-voltage stabilizer yesigaba esinye ihlala ibhekisa kwigalelo kunye nemveliso ye-220V eTshayina, kwaye igalelo ngokubanzi kunye nemigca yemveliso ngumgca ongathathi hlangothi kunye nomgca ophilayo, emva koko umgca osezantsi wongezwe, kwaye le migca mithathu isetyenziswa njenge izigaba zegalelo kunye nemveliso.
Izilawuli zombane zenqanaba elinye zihlala zisetyenziswa kwizixhobo zombane ezisezantsi njengezixhobo zasekhaya, izixhobo zeofisi, kunye nezixhobo zovavanyo ezincinci.


Izilawuli zombane zamanqanaba amathathu zihlala ziyaziwa kubasebenzisi beesekethe. Amandla amanqanaba amathathu ngokubanzi abhekisa kumandla oshishino 380V. I-input yayo kunye ne-output wiring idla ngokudibaniswa ngamacingo amathathu aphilayo. Indlela yokufaka i-wiring ye-three-three-three-three-three, i-three-phase-four-wire, i-Five-phase ye-five-five, njl.
Umahluko phakathi kwezi zibini kukuba igalelo kunye nemveliso yombane kunye nenani lemigca yokufikelela iyahluka, kwaye isakhiwo sangaphakathi kunye nokusetyenziswa nazo zihluke. Ekusetyenzisweni, izilawuli ze-voltage zesigaba esisodwa zisetyenziselwa kuphela ukunikezelwa kwamandla ombane wesigaba esisodwa, ngelixa izilawuli ze-voltage zesigaba sesithathu zinokuba zizigaba ezintathu Ukunikezelwa kwamandla kunika amandla amanqanaba amathathu. Ngokweemfuno ezikhethekileyo zefektri kwinkqubo yokuvelisa, ingasetyenziselwa ukunikezelwa kwamandla kwisigaba esisodwa.
