Umgca ongaphezulu ubhekiselele kumgca ongaphezulu ovulekileyo omiswe phantsi, ongumgca wamandla ombane omiswe kwi-pole tower ene-insulators kunye nezixhobo zombane.Yenziwe ngocingo kunye nocingo lomhlaba (umcingo ongaphezulu komhlaba), inqaba, isigqubuthelo, i-hardware, kunye namanye amacandelo esiseko senqaba, i-ankile kunye nesixhobo sokumisa, ucingo lwenziwe ngesinyithi esilungileyo, kukho icandelo elishinyeneyo elaneleyo gcina ukuxinana kokuhamba okufanelekileyo) kunye neradiyasi enkulu yokugoba (ukunciphisa ukukhutshwa kwe-corona) kunye nokuhanjiswa kwamandla ombane aphezulu ngokuqinisekileyo kukusebenzisa i-conductor eyahlulahlula;Umtya we-insulator uqulunqwe ngumtya owodwa wokumisa (okanye ibha) ye-insulator, ekufuneka ihlangabezane neemfuno zamandla e-insulator kunye namandla omatshini, kwaye inani le-insulators kumtya ngamnye lichongwa yinqanaba lombane lokuhambisa.Iipali kunye neenqaba, ubukhulu becala zenziwe ngentsimbi okanye ikhonkrithi eyomeleziweyo, zezona zakhiwo zenkxaso kwiintambo zokuhambisa ngaphezulu...
Sibona imigca engaphezulu idla ngokuxhonywa kucingo oluvulekileyo emhlabeni, umhlaba unobude obuthile, kodwa, ngoku, andazi ukusuka nini ukuya phambili, imigca engaphezulu iqala yanyamalala kwimbono yethu, ukunyamalala akuthethi ukuba akukho ngaphaya. imigca apha, kunjalo, kodwa le migca engaphezulu ingena emhlabeni, kwaye yangcwatywa emhlabeni.Kuqhubeka ntoni apha?Inceda ntoni i-overhead line ukuya emhlabeni?Okulandelayo, ukuthetha nawe malunga nomgca ongaphezulu kulwazi olunxulumene nomhlaba, ndiyathemba ukuba unokuqonda.
Ngaphambi kokuba siqale ukuthetha ngeenzuzo zomgca womoya emhlabeni, siqale sijonge iimeko ezimbalwa zeendaba: iSithili saseTongzhou icandelo elidala likarhulumente wasentshona, iSongzhuang Road, i-Defence South Road Defense Road, indlela yaseHongyun Science kunye neTekhnoloji yePaki kunye nezinye iindlela ezingama-83. , "umgca we-airline wonxibelelwano emhlabeni" kwezi ndlela, ubude bendlela yi-45.398 yeekhilomitha, uqikelelo lotyalo-mali lweprojekthi: 137,425,900;I-Baotou Industrial Road esemazantsi ecandelo lendlela enkulu (ukusuka kwisitalato i-Dongmen ukuya kwi-Zhanbei Road) umgca ongaphezulu kufuneka ungene emhlabeni;I-Shanghai Xuhui kunye ne-Changning, i-Sichuan, nazo zisebenza kunye ukutyhala umgca ongaphezulu emhlabeni kunye nomsebenzi wokudibanisa…… Ezi ndaba ziimeko zakutsha nje zocingo olungaphezulu emhlabeni.
Kutheni le nto iingcingo eziphezulu zingena emhlabeni?Ngoko ke yintoni inzuzo yokungena kumgca ongaphezulu?Kufuneka siqonde isizathu somgca ongaphezulu emhlabeni, kuxelwe ukuba iindawo ezininzi zifuna umgca ongaphezulu emhlabeni, kuba umgca we-overhead ulula ukuchatshazelwa yimeko yokusingqongileyo, ukuze imigca yezi ndawo ivame ukucinywa kombane, "Ivenkile ayinabuganga bokusebenzisa izixhobo zombane eziphezulu", ukoyika xa kukho iindudumo kunye nemvula, kubangele iingxwelerha.Nangona kunjalo, emva komgca we-overhead ukuya emhlabeni, akufani, ngokulungiswa, indlela emacaleni omabini olutsha, ilungele ukuphuculwa kokusingqongileyo kwedolophu;Ngokufanelekileyo ukuphepha ukusilela kwenethiwekhi yokusabalalisa okubangelwa yimozulu embi kunye nomonakalo wangaphandle, ukunciphisa kakhulu inani kunye nobubanzi bokungaphumeleli kwamandla, ngelixa uphucula ukhuseleko kunye nokuthembeka kwegridi yamandla, eyinzuzo enkulu kuthi.
