Ukuvikelwa kombani kwesiteshi esincane Ukuze uthole ukuvikelwa kombani womugqa, ukuvikelwa kombani okuyingxenye kuphela kuyadingeka, okungukuthi, ngokusho kokubaluleka komugqa, kuphela izinga elithile lokumelana nombani elidingekayo. Futhi embonini yamandla, isiteshi esincane sasidinga ukumelana nombani okuphelele. Izingozi zombani ezitshalweni zikagesi kanye neziteshi ezingaphansi zivela ezicini ezimbili: umbani ushaya ngokuqondile ezitshalweni zikagesi neziteshi ezincane; Umbani emigqeni yokudlulisa umbani udala amaza ombani ahlasele izikhungo zikagesi neziteshi ezincane endleleni. Ukuze uvikele isiteshi esingaphansi ekushayweni kombani oqondile, udinga ukufaka izinduku zombani, izinduku zombani, namanetha aphansi abekwe kahle. Ukufakwa kwezinduku zombani (izintambo) kufanele kwenze zonke izinto zokusebenza nezakhiwo esiteshini esincane ngaphakathi kwebanga lokuvikela; Kufanele futhi kube nesikhala esanele phakathi kwento evikelayo kanye nenduku yombani (intambo) esemoyeni kanye nensiza engaphansi komhlaba ukuze kuvinjelwe ukuhlasela (i-flashover ehlehlayo). Ukufakwa kwenduku yombani kungahlukaniswa induku yombani ezimele kanye nenduku yombani enefreyimu. Ukumelana nokuqina kwemvamisa yamandla kwenduku yombani eqondile akufanele ibe ngaphezu kuka-10 ohms. I-insulation yamayunithi okusabalalisa amandla afinyelela ku-35kV ayinamandla. Ngakho-ke, akufanelekile ukufaka induku yombani enefreyimu, kodwa induku yombani ozimele. Ibanga likagesi phakathi kwendawo yokuxhuma engaphansi komhlaba yenduku yombani kanye nenethiwekhi eyisisekelo eyisisekelo kanye nephuzu eliphansi le-transformer enkulu kufanele libe likhulu kune-15m. Ukuze kuqinisekiswe ukuphepha kwe-transformer eyinhloko, ukuboshwa kombani akuvunyelwe ukufakwa kuhlaka lomnyango we-transformer.
