Ulwakhiwo Oluqinileyo:
Ezi ndawo zokungenisa umoya zakhiwe ukuze zikwazi ukumelana neemeko ezinzima zokusingqongileyo, kuquka amaqondo obushushu agqithisileyo, ukufuma, kunye nokuvezwa ziikhemikhali, okuqinisekisa ukuthembeka nokuqina kwexesha elide.
Ukuvala kunye nokukhusela:
Iisokhethi zekhebula ezinombane ophezulu zisebenzisa izinto zokukhusela kunye nezokukhusela ukuthintela ukuvuza nokuqinisekisa ukudluliselwa kwamandla ngokukhuselekileyo, nto leyo enciphisa umngcipheko weengozi zombane kunye neengozi.
Iimpawu zokuchonga iimpazamo kunye nokhuseleko:
Ezinye iisokhethi zekhebula ezinombane ophezulu zixhotyiswe ngeenkqubo zokubona iimpazamo ezinokubona ngokukhawuleza kwaye zihlukanise naziphi na iimpazamo zombane, nto leyo eyandisa ukhuseleko kwaye inciphise ixesha lokungasebenzi.
Ukuphucula ukusebenza kakuhle kokudluliselwa kwamandla:
Iisokhethi zekhebula ezine-voltage ephezulu zidlala indima ebalulekileyo ekuphuculeni ukusebenza kakuhle kothumelo lwamandla. Uyilo lwayo olusebenzayo kunye nokusebenza kwayo kunceda ukufezekisa ezi njongo zilandelayo:
Nciphisa ukulahleka kwamandla:
Iisokhethi zekhebula ezine-voltage ephezulu, ukuba zifakelwe kwaye zigcinwe ngokuchanekileyo, zinokunciphisa ukulahleka kombane ngexesha lokudluliselwa kombane, ziqinisekise ukuhanjiswa kombane ngokufanelekileyo kwaye zinciphise inkunkuma yamandla iyonke.
Ukuthembeka kwenkqubo okuphuculweyo:
Iiplagi zekhebula ezinombane ophezulu ezinokuthenjwa zinceda ekwandiseni ixesha lokusebenza kwenkqubo ngokuthintela iimpazamo zombane kunye nokusilela, ukunciphisa ixesha lokungasebenzi kunye nokwandisa ukuthembeka kwenethiwekhi yokusasazwa kwamandla. Khuthaza ukuhlanganiswa kwamandla avuselelekayo kwigridi: Iiplagi zekhebula ezinombane ophezulu zidlala indima ebalulekileyo ekuhlanganisweni kwamandla avuselelekayo kwigridi.
