Ukuzincamathelisa okanye ukuzibophelela ngocingo lobhedu olunameleli, oko kukuthi ucingo lwemagnethi olunamathela ngokuzenzekelayo lunikwe iimeko ezithile zangaphandle (ubushushu okanye ukudityaniswa kotywala).
SBEIW Ubushushu obunganyangekiyo obuzibophelelayo ngocingo lobhedu olunameleli olunemityatho edibeneyo lunokusetyenziselwa ukujija xa lusebenza ngokubhaka okanye ukufudumeza kombane ukwenza idyasi yebhondi yocingo encanyathiselwe enye kwenye kwaye imise ucingo lube lulonke ngokuzenzekelayo kwaye lucuthene emva kokupholisa. .
Zombini ubhedu olusulungekileyo kunye nobhedu oluhonjiswe nge-aluminiyam zingasetyenziswa zombini njenge-conductor yocingo xa kukho iimfuno ezahlukeneyo zomgangatho wethowuni.Uphononongo lubonisa ukuba ukucoceka okuphezulu kobhedu kunenzuzo ekuphuculeni umgangatho wesandi.Ingabonwa ukuba i-4N ecocekileyo (99.99%) yobhedu idla ngokuthathwa kwiimarike.
