Transmission line towerziyizakhiwo ezibalulekile ezisetshenziselwa ukusekela izintambo zokudlulisela futhi zingahlukaniswa ngezinhlobo ezahlukene ngokusekelwe emiklamweni nasekusetshenzisweni okuhlukene. Kunezinhlobo ezintathu zomugqa wombhoshongo wokudlulisela:i-angle steel tower, umbhoshongo we-tube yokudluliselafuthii-monopole, kodwa umbhoshongo kagesi uza ngezitayela ezihlukahlukene, okulandelayo yisingeniso esifushane sezinhlobo eziningana ezivamile zama-pylons amandla:

1. Umbhoshongo weGantry

Njengoba igama liphakamisa, amakholomu amabili okusekela umqhubi kanye nombhoshongo ongaphezulu womugqa ophansi, "njengomnyango" omkhulu. Lokhu kusebenza kombhoshongo kukhulu uma kuqhathaniswa, kunomugqa wokudonsa unomnotho omuhle, ovame ukusetshenziswa endaweni engaphezulu kabili futhi umqhubi uhlelwe ngokuvundlile, ngokuvamile usetshenziselwa ulayini ongu-≥ 220 kV, ungasetshenziswa ukuthuthukisa ukuzinza kombhoshongo, ikholomu ngezinye izikhathi. ngomthambeka othile.

Umbhoshongo omise okwe-2.V

Umugqa wokubopha umbhoshongo omise okwe-V, ikesi elikhethekile lombhoshongo womnyango, omise okwe-"V", ufika "nesitifiketi esikhulu se-V", ngakho-ke ehlane kuyabonakala kakhulu. Kulula ukuyakha, futhi ukusetshenziswa kwensimbi kuphansi kunakweminye imibhoshongo enesango elidonswe ngocingo, kodwa ithatha indawo enkulu, futhi ukusetshenziswa kwayo kunethiwekhi yomfula kanye nezindawo ezinkulu zokulinywa ngemishini kungaphansi kwemikhawulo ethile. Okuvame ukusetshenziswa emigqeni engu-500 kV, ku-220 kV futhi ibe nenani elincane lokusebenzisa.

Umbhoshongo omise okwe-3

Umbhoshongo wawuwuhlobo lwe-“T”, Umbhoshongo omise okwe-T uyingxenye ebalulekile yengqalasizinda yokudlulisa amandla, esebenza njengombhoshongo oyinhloko wokudlulisa amandla e-DC. Idizayinelwe ngemigqa yokudlulisela emibili elenga ngezansi ekucushweni okumise okuka-T, nohlangothi olulodwa lokudluliswa kwe-positive kanye nolunye ukudlulisela okunegethivu. Lapho ebhekisisa, umuntu angabona “amakhona” amabili amancane phezulu kombhoshongo, enohlangothi olulodwa oluklanyelwe umugqa ophansi nolunye umugqa wombani. Lo mklamo uqinisekisa ukuzinza nokuphepha kwesistimu yokudlulisa amandla, ikakhulukazi uma kwenzeka umbani ushaya.
