Umurongo woherezaninzego zingenzi zikoreshwa mugushigikira imirongo yoherejwe kandi irashobora gushyirwa mubwoko butandukanye bushingiye kubishushanyo mbonera no gukoresha. Hano hari ubwoko butatu bwumurongo wumurongo:Inguni y'icyuma, umuyoboro wa tubenamonopole, ariko umunara wamashanyarazi uza muburyo butandukanye bwuburyo, ibikurikira nintangiriro ngufi kubwoko butandukanye busanzwe bwa pylons:

1． Umunara

Nkuko izina ribigaragaza, inkingi ebyiri zo gushyigikira umuyobozi nu munara wubutaka hejuru yumurongo, nk "umuryango" munini. Uyu munara ushobora gukoreshwa ni munini, hamwe n'umurongo wo gukurura ufite ubukungu bwiza, usanzwe ukoreshwa mubutaka bubiri hejuru kandi kiyobora itunganijwe neza, ubusanzwe ikoreshwa kumurongo wa 220 kV, irashobora gukoreshwa mugutezimbere umunara, inkingi rimwe na rimwe n'umusozi runaka.

Umunara umeze nka V.

Umurongo uhuza umunara wa V, umunara wumuryango udasanzwe, umeze nka "V", uzana "icyemezo kinini cya V", bityo mubutayu buramenyekana cyane. Biroroshye kubaka, kandi gukoresha ibyuma biri munsi yubwa iyindi minara yashizwemo insinga zometseho insinga, ariko ifata ahantu hanini, kandi ikoreshwa ryayo mumigezi yinzuzi hamwe n’ahantu hanini ho guhingira imashini hashobora kugarukira. Bikunze gukoreshwa mumirongo 500 kV, muri 220 kV nayo ifite umubare muto wo gukoresha.

3.Umunara umeze

Umunara wari ubwoko bwa "T", umunara umeze nka T ni igice cyingenzi mubikorwa remezo byo gukwirakwiza amashanyarazi, nkumunara munini wohereza DC. Yashizweho hamwe nimirongo ibiri yohereza imanitse hepfo muburyo bwa T-shusho, hamwe uruhande rumwe rwo kohereza neza urundi rwohereza nabi. Iyo ugenzuye neza, umwe ashobora kwitegereza “inguni” ebyiri ntoya hejuru yumunara, uruhande rumwe rwagenewe umurongo wubutaka urundi rukaba kumurongo wumurabyo. Igishushanyo cyerekana umutekano n'umutekano bya sisitemu yo gukwirakwiza amashanyarazi, cyane cyane mugihe habaye inkuba.
