1.Imibhoshongo yokudluliselanamazinga kagesi angu-110kV nangaphezulu
Kulolu hlu lwamandla kagesi, imigqa eminingi iqukethe ama-conductor angu-5. Amakhondaktha amabili aphezulu abizwa ngezintambo ezivikelekile, ezaziwa nangokuthi izintambo zokuvikela umbani. Umsebenzi oyinhloko walezi zintambo ezimbili ukuvimbela umqhubi ukuba ashaywe umbani ngokuqondile.
Amakhondakta amathathu aphansi amakhondatha esigaba A, B, kanye no-C, avame ukubizwa ngokuthi amandla ezigaba ezintathu. Ukuhlelwa kwalawa ma-conductor ezigaba ezintathu kungahluka kuye ngohlobo lombhoshongo. Ngohlelo oluvundlile, amakhondatha ezigaba ezintathu asendizeni efanayo evundlile. Emigqani yesifunda esisodwa, kukhona nokuhlelwa okuvundlile esimweni sohlamvu "H". Ngemigqa eyiziyingi ezimbili noma eyiziyingi eziningi, ukuhleleka okuqondile kuvame ukwamukelwa. Kuyaphawuleka ukuthi imigqa embalwa ye-110kV inocingo olulodwa kuphela oluvikelwe, okuholela kumakhondatha angu-4: ucingo oluvikelekile olu-1 kanye namakhondatha ezigaba ezi-3.
2.35kV-66kV umbhoshongo wokudlulisa izinga likagesi
Imigqa eminingi ephezulu kulolu hlu iqukethe amakhondaktha angu-4, ongaphezulu kwawo osavikelekile futhi emithathu ephansi abaqhubi besigaba.
3.10kV-20kV umbhoshongo wokudlulisa izinga likagesi
Imigqa eminingi ephezulu kulobu bubanzi iqukethe amakhondatha angu-3, wonke amakhondatha esigaba, asikho isivikelo. Lokhu kubhekiselwa kumigqa yokudlulisa yesekethe eyodwa. Njengamanje, olayini abangu-10kV ezindaweni eziningi bangamalayini asakazwa ngamasekethe amaningi. Isibonelo, umugqa we-double-circuit uqukethe ama-conductor angu-6, futhi umugqa we-circuit ezine uqukethe ama-conductor angu-12.
4.Low-voltage overhead transmission tower (220V, 380V)
Uma ubona ulayini ongaphezulu onamakhondaktha amabili kuphela esigxotsheni sikakhonkolo esiphansi kanye nebanga elifushane phakathi kwawo, lokhu ngokuvamile ulayini ongu-220V. Le migqa ayivamile ezindaweni zasemadolobheni kodwa ingase ibonakale ezindaweni zasemakhaya ezibamba ukushisa. Amakhondaktha amabili ahlanganisa ikhondakta yesigaba kanye nekhondatha engathathi hlangothi, okungukuthi amakhondaktha aphilayo naphakathi nendawo. Okunye ukucushwa ukusethwa kwe-4-conductor, okuwumugqa we-380V. Lokhu kufaka izintambo ezi-3 ezibukhoma kanye nentambo emaphakathi e-1.
