Ingu-220kV ejwayelekileumbhoshongo wokudlulisela,owaziwa nangokuthi umbhoshongo wokudlulisa amandla, uklanyelwe ukusekela izintambo zamandla kagesi aphezulu ezithwala ugesi amabanga amade. Ubude bale mibhoshongo bungahluka ngokuya ngezinto ezimbalwa, okuhlanganisa indawo, indawo, kanye nezimfuneko ezithile zolayini wamandla abawusekelayo. Ngokuvamile, a220kV umbhoshongoisukela kumamitha angama-30 kuye kwangama-50 (cishe amafidi angama-98 kuye kwangama-164) ubude. Lokhu kuphakama kuyadingeka ukuze kuqinisekiswe ukuthi izintambo zokudlulisela ziphakanyiswa ngokuphephile ngaphezu kwezinga eliphansi, ukunciphisa ubungozi bokuthintwa ngengozi nabantu, izimoto, noma izilwane.

Umklamo we-atransmission power line towerakukhona nje ukuphakama; kuhlanganisa nokucatshangelwa kobunjiniyela okuqinisekisa ukuzinza nokuqina. Le mibhoshongo ivamise ukwakhiwa ngensimbi noma ukhonkolo oqinisiwe, izinto ezikhethwa ngamandla azo kanye nokumelana nezinto zemvelo. Isakhiwo kufanele simelane namandla ahlukahlukene, okuhlanganisa umoya, iqhwa, kanye nesisindo sezintambo zokudlulisela ngokwazo.

Ngaphezu kobude, isikhala phakathiimibhoshongo yokudluliselaesinye isici esibalulekile sokuklama kwazo. Ngombhoshongo kagesi ongu-220kV, ibanga phakathi kwemibhoshongo lingasuka kumamitha angama-200 kuye kwangama-400 (cishe amafidi angama-656 kuye kwayi-1,312). Lesi sikhala sinqunywa izici zikagesi nezemishini zezintambo zokudlulisa, kanye nemithetho yezokuphepha elawula ukudluliswa kwamandla.

Phezulutransmission line towers, okuhlanganisa nohlobo lwama-220kV, avame ukuhlonyiswa ngezinsimbi ezivimbela amandla kagesi ukuthi angavuzi endaweni ezungezile. Lawa ma-insulators abalulekile ekugcineni ukusebenza kahle kokudluliswa kwamandla kanye nokuqinisekisa ukuphepha kwendawo ezungezile. Inhlanganisela yobude, isikhala, kanye nobuchwepheshe be-insulator ivumela le mibhoshongo ukuthi ithwale ngempumelelo ugesi wamandla kagesi aphezulu ebangeni elikhulu.

Iqhaza lemibhoshongo yokudlulisa idlulela ngale kokusebenza nje; futhi zisebenza njengesithombe esibonakalayo sengqalasizinda kagesi enika amandla izimpilo zethu zesimanje. Ukubonakala kombhoshongo wamapayipi okudlulisela ugesi uma ubhekene nesibhakabhaka kuyisikhumbuzo sezinhlelo eziyinkimbinkimbi eziletha ugesi ezindlini zethu nasemabhizinisini ethu.

Eminyakeni yamuva nje, kuye kwaba nokugcizelela okukhulayo ekuhlanganisweni kobuhle bemibhoshongo yokudlulisela endaweni. Ezinye izifunda seziqalile ukuhlola amadizayini anciphisa umthelela obonakalayo ngenkathi zisahlangabezana nezindinganiso ezidingekayo zobunjiniyela. Lo mkhuba ukhombisa ukuqwashisa okubanzi ngokubaluleka kokulinganisa izidingo zengqalasizinda nokucatshangelwa kwemvelo kanye nomphakathi.
