Ulayini ongaphezulu ubhekisela kulayini ovulekile ongaphezulu omiswe phansi, okuwumugqa wamandla kagesi omiswe esigxotsheni esinama-insulators kanye nezixhumi zamandla.Yakhiwe ngocingo kanye nocingo oluphansi (intambo yomhlabathi engaphezulu), umbhoshongo, isivikelo, ihadiwe, nezinye izingxenye zesisekelo sombhoshongo, ihange kanye nomshini wokumisa phansi, ucingo lwenziwe ngensimbi esebenza kahle, kunengxenye ewugqinsi eyanele gcina ukuminyana kokugeleza okufanele) kanye ne-radius enkulu yokugoba (ukunciphisa ukukhishwa kwe-corona) kanye nokudluliswa kwamandla kagesi aphezulu kakhulu kusetshenziswa i-split conductor;Iyunithi yezinhlamvu ze-insulator yakhiwe ngochungechunge olulodwa lokumisa (noma ibha) lokuvikela, okufanele luhlangabezane nezidingo zamandla okushisa kanye namandla omshini, futhi inani lama-insulators kuchungechunge ngalunye linqunywa izinga le-voltage yokudlulisela.Izigxobo nemibhoshongo, iningi labo elakhiwe ngensimbi noma ukhonkolo oqinisiwe, yizona zakhiwo eziyinhloko ezisekela imigqa yokudlulisela phezulu…
Sibona imigqa engaphezulu ivame ukugxunyekwa ocingweni oluvulekile phansi, inhlabathi inobude obuthile, kodwa, manje, futhi asazi ukuthi kusukela nini, imigqa ephezulu iqala ukunyamalala ekubukeni kwethu, ukunyamalala akusho ukuthi akukho phezulu. Imigqa lapha, kunjalo, kodwa lemigqa engaphezulu ingena emhlabathini, futhi yagqitshwa emhlabathini.Kwenzakalani lapha?Kusizani ukuthi ulayini ongaphezulu uya emhlabathini?Okulandelayo, ukuze ngikhulume nawe mayelana nomugqa ongaphezulu kulwazi oluhlobene nomhlabathi, ngithemba ukuthi ungaqonda.
Ngaphambi kokuba siqale ukukhuluma ngezinzuzo zolayini basemoyeni emhlabathini, siqale sibheke izindaba ezimbalwa: Isifunda sikahulumeni omdala sase-Tongzhou ingxenye esentshonalanga, i-Songzhuang Road, i-Defence South Road Defense Road North, umgwaqo i-Hongyun Science and Technology Park neminye imigwaqo engu-83. , “umugqa wendiza wokuxhumana ungene emhlabathini” kule migwaqo, ubude bomgwaqo ungamakhilomitha angu-45.398, isilinganiso sokutshalwa kwezimali kwephrojekthi: 137,425,900;I-Baotou Industrial Road engxenyeni eseningizimu yomgwaqo omkhulu (kusuka ku-Dongmen Street ukuya ku-Zhanbei Road) umugqa ongaphezulu kufanele ungene phansi;I-Shanghai Xuhui kanye ne-Changning, i-Sichuan, nazo zisebenza ndawonye ukuze zisunduze ulayini ongaphezulu emsebenzini wokuhlanganisa …… Lezi zindaba yizigameko zakamuva zocingo oluphezulu emhlabathini.
Ngokuqondene nokuthi kungani izintambo ezingaphezulu zingena emhlabathini?Ngakho-ke yiziphi izinzuzo zokungena komugqa ophezulu?Kufanele siqonde isizathu somugqa ongaphezulu komhlaba, kubikwa ukuthi izindawo eziningi zidinga ulayini ongaphezulu emhlabathini, ngoba ulayini ongaphezulu kulula ukuthintwa izimo zemvelo, ukuze imigqa yalezi zindawo ivamise ukucisha ugesi, “isitolo asilokothi sisebenzise izinto zikagesi ezinamandla amakhulu”, sisaba uma kuduma izulu nemvula, okubangela ukulimala.Kodwa-ke, ngemva komugqa ongaphezulu ungene emhlabathini, akufani, ngokulungiswa, umgwaqo ezinhlangothini zombili zomusha, osiza ekuthuthukisweni kwemvelo yasemadolobheni;Gwema ngokuphumelelayo ukwehluleka kwenethiwekhi yokusabalalisa okubangelwa isimo sezulu esibi kanye nokulimala kwangaphandle, ukunciphisa kakhulu inombolo kanye nobubanzi bokuhluleka kwamandla, kuyilapho uthuthukisa ukuphepha nokuthembeka kwegridi yamandla, okuyinzuzo enkulu kithi.
