Olunye uhlobo oluqhelekileyo lweinqaba yothumeloIngaba iinqaba yentsimbi ye-engile, eyakhiwe kusetyenziswa amacandelo ensimbi ye-angle. Ezi nqaba zisetyenziswa ngokubanzi ekwakhiweni kweentambo zothumelo lwe-voltage ephezulu ngenxa yamandla azo, ukuqina, kunye nokusebenza kakuhle kweendleko. Uyilo lwe-angle yensimbi yensimbi luvumela ukuba lukwazi ukumelana nemikhosi eyenziwa yimigca yokuhambisa kunye neemeko zokusingqongileyo apho zifakwe khona.

Iinqaba zoxinzelelolelinye icandelo elibalulekileyo leziseko zothumelo lwentambo. Ezi nqaba zenzelwe ngokukodwa ukuxhasa ukuxinana kweentambo zothumelo, ziqinisekisa ukuba zihlala ziqinile kwaye zikhuselekile, naphantsi kweemeko zemozulu ezahlukeneyo. Iiinqaba zombane ophezuluzenzelwe ukumelana noxinzelelo lombane kunye noomatshini olubekwe ziintambo zothumelo, zibonelela ngeendlela ezizinzileyo nezithembekileyo zokuhambisa umbane kumgama omde.

Ukwakhiwa kunye nokugcinwa kweiinqaba zothumelozibaluleke kakhulu ekuthembekeni ngokubanzi kunye nokusebenza kakuhle kwegridi yamandla. Iinqaba eziyilwe ngokufanelekileyo zaza zafakelwa zibalulekile ekuqinisekiseni ukuhanjiswa kombane okukhuselekileyo nokungaphazanyiswa, ngeli lixa kucutha umngcipheko wokucinywa kombane kunye nokuphazamiseka.

Ukuqukumbela, iinqaba zothumelo, kubandakanywa iinqaba zentsimbi, iinqaba zoxinzelelo, kunye neenqaba zombane ophezulu, zizinto ezibalulekileyo kuthungelwano lokuhambisa amandla ombane. La maqumrhu adlala indima ebalulekileyo ekuxhaseni iintambo zothumelo ezithwala umbane onamandla ombane omkhulu, ukuqinisekisa unikezelo lwamandla oluthembekileyo kuluntu nakumashishini. Njengoko ubuchwephesha buqhubela phambili, uphuhliso loyilo lweenqaba zothumelo oluyilayo luya kuphucula nangakumbi ukusebenza kakuhle nokomelela kwegridi yamandla, kube negalelo kwiziseko ezingundoqo zamandla ezizinzileyo nezithembekileyo.
