Umqondo oyisisekelo wokuvikela umbani wemigqa yokudlulisela Ngenxa yobude obukhulu bezintambo zokudlulisela, zichayeka ehlane noma ezintabeni, ngakho maningi amathuba okushaywa umbani. Ngolayini ka-100-km ongu-110kV kagesi, isilinganiso senani lokushaywa kombani ngonyaka sicishe sibe ishumi nambili endaweni ephakathi nendawo. Isipiliyoni sokusebenza siphinde sifakazele ukuthi ulayini ubangela izingozi eziningi zombani ohlelweni lukagesi. Ngakho-ke, uma ulayini wokudlulisela ungathathi izinyathelo zokuvikela umbani, awukwazi ukuqinisekisa ukusebenza okuphephile. Ukuvikelwa kombani kwezintambo zokudlulisela kufanele ngokuvamile kulandele izimiso ezine eziyisisekelo ezilandelayo: 1. Qinisekisa ukuthi u-conductor akashaywa umbani. 2. Uma umugqa wokuqala wokuzivikela uhluleka futhi ucingo lushaywa umbani, kuyadingeka ukuqinisekisa ukuthi ukufakwa komugqa akunawo umthelela we-flashover. I-3, uma umugqa wesibili wokuzivikela uhluleka, i-flashover ye-insulation inomthelela we-flashover, kuyadingeka ukuqinisekisa ukuthi le flashover ngeke iguqulwe ibe yi-arc ezinzile yefrikhwensi yamandla, okungukuthi, ukuqinisekisa ukuthi umugqa awenzeki iphutha lesifunda esifushane, alukho uhambo. 4. Uma umugqa wesithathu wokuzivikela uhluleka futhi umugqa uhamba, kuyadingeka ukuqinisekisa ukuthi umugqa ugijima ngaphandle kokuphazamiseka. Akuyona yonke imizila okufanele ibe nalezi zimiso ezine eziyisisekelo. Lapho sinquma imodi yokuvikela umbani yolayini wokudlulisela, kufanele sicabangele ngokugcwele ukubaluleka kolayini, amandla omsebenzi wombani, izici ze-topography kanye nokuma komhlaba, izinga lokumelana nomhlabathi nezinye izimo, bese sithatha izinyathelo zokuvikela ezifanele ngokuya izimo zendawo ngokuya ngemiphumela yokuqhathanisa kwezobuchwepheshe nezomnotho.
