1. igitekerezo cyo kohereza (kohereza) imirongo
Umurongo wohereza (guhererekanya) uhujwe n’urugomero rwamashanyarazi na sitasiyo (biro) yohereza imirongo yamashanyarazi.
2. urwego rwa voltage yumurongo wohereza
Imbere mu gihugu: 35kV, 66kV, 110kV, 220kV, 330kV, 500kV, 750kV, ± 80okV.1000kV.
Intara: 35kV, 110kV, 220kV, 500kV, ± 8ookV
3. Gutondekanya imirongo yohereza
(1) ukurikije imiterere yikwirakwizwa: imirongo ya AC, imirongo ya DC.
(2) ukurikije imiterere: imirongo yohereza hejuru, imirongo ya kabili.
Ibigize ibice byingenzi bigize umurongo wohereza hejuru: umuyobozi, umurongo wumurabyo (byitwa umurongo wumurabyo)
Ibikoresho, insulator, iminara, insinga na fondasiyo, ibikoresho byo hasi.
Umunara wumurongo wo hejuru usanzwe ushingiye kubikoresho, imikoreshereze, umubare wumuzunguruko, imiterere nuburyo nibindi.
4. Ibyiciro
.
.Umunara muto (pole) umunara, hakurya (pole) umunara.

5. Ibibazo byumurongo umwe wohereza.
Mu turere twateye imbere mu bukungu kandi dutuwe cyane, umutungo wubutaka ni muto cyane, gusa kubaka umurongo umwe wohereza.
Kubaka imirongo imwe yumuzunguruko ntishobora kongera guhaza amashanyarazi.
Imirongo myinshi ihinduranya umunara umwe nuburyo bwiza bwo kuzamura ubushobozi bwo kohereza umurongo wa koridor, ntibishobora kongera ubushobozi bwo kohereza kuri buri gice cyumurongo, ariko kandi byongera ubushobozi bwumurongo.
Agace k'umuhanda ubushobozi bwo kohereza, kongera amashanyarazi, ariko kandi bigabanya igiciro rusange.
Mu Budage, guverinoma iteganya ko imirongo mishya yose igomba gushyirwaho ku munara umwe inshuro zirenga ebyiri.Mumurongo mwinshi-ultra-high-voltage umurongo
Umuhanda, kumunara umwe inshuro enye kumirongo isanzwe, kugeza inshuro esheshatu.Kuva mu 1986, umunara umwe hamwe n'ikadiri myinshi-isubiramo umurongo uhuza uburebure bwa metero 2000.
Kuva mu 1986, uburebure bwuzuye bwimirongo myinshi ihinduranya hamwe numunara umwe byari hafi 27.000km, kandi hari uburambe bwimyaka irenga 50 yo gukora.
Mu Buyapani, imirongo myinshi ya 110 kV no hejuru yayo ni imirongo ine ifite umunara umwe, naho imirongo ya 500 kV yose ni umuzenguruko umwe ufite umunara umwe, usibye iyambere.
Imirongo 500kV, usibye imirongo ibiri yumuzunguruko muminsi yambere, byose ni imirongo ibiri kuminara imwe.Kugeza ubu, umubare ntarengwa w’umuzunguruko ku munara umwe mu Buyapani ni umunani.
Mu myaka yashize, hamwe n’ubwubatsi bwihuse bw’amashanyarazi, Guangdong n’utundi turere dufite umunara umwe washyizwemo imizunguruko nayo irasa naho ihinduka ikoranabuhanga rikuze.
