Transmission Tower,yomwe imadziwikanso kuti transmission line tower, ndi mawonekedwe atatu-dimensional omwe amagwiritsidwa ntchito kuthandizira mizere yamagetsi yam'mwamba ndi mizere yoteteza mphezi pamagetsi othamanga kwambiri kapena okwera kwambiri. Kuchokera pamawonekedwe, nsanja zotumizira nthawi zambiri zimagawidwa kukhalangodya zitsulo nsanja, zitsulo chubu nsanjandi nsanja zopapatiza zazitsulo zamachubu. Zomangamanga zachitsulo zimagwiritsidwa ntchito kumadera akumidzi, pomwe mitengo yachitsulo ndi nsanja zopapatiza zazitsulo ndizoyenera kumatauni chifukwa chocheperako. Ntchito yayikulu ya nsanja zotumizira ndikuthandizira ndi kuteteza mizere yamagetsi ndikuwonetsetsa kugwira ntchito kokhazikika kwamagetsi. Amatha kupirira kulemera ndi kupsinjika kwa mizere yopatsirana ndikumwaza mphamvuzi ku maziko ndi pansi, potero kuonetsetsa kuti mizereyo ikuyenda bwino komanso yokhazikika. Kuphatikiza apo, amateteza mizere yotumizira ku nsanja, kuwalepheretsa kuti asaduke kapena kusweka chifukwa cha mphepo kapena kusokonezedwa ndi anthu. Zinsanja zopatsirana zimapangidwanso ndi zida zotchingira kuti zitsimikizire kuti mizere yolumikizira imagwira ntchito, kupewa kutayikira ndikuwonetsetsa chitetezo. Kuphatikiza apo, kutalika ndi mawonekedwe a nsanja zotumizira zimatha kupirira zovuta monga masoka achilengedwe, kuwonetsetsa kuti njira zotumizira zikuyenda bwino komanso zokhazikika.
Kutengera cholinga,nsanja zotumiziraakhoza kugawidwa mu nsanja kufala ndi nsanja kugawa. Zinsanja zotumizira zimagwiritsidwa ntchito makamaka pamizere yamagetsi othamanga kwambiri kuti ayendetse mphamvu kuchokera ku magetsi kupita ku malo ang'onoang'ono, pamene nsanja zogawira zimagwiritsidwa ntchito pamizere yapakati ndi yotsika kwambiri yogawa mphamvu kuti igawike mphamvu kuchokera kumagulu kupita kwa ogwiritsa ntchito osiyanasiyana. Malinga ndi kutalika kwa nsanjayo, imatha kugawidwa kukhala nsanja yotsika-voltage, nsanja yothamanga kwambiri komanso nsanja yopitilira muyeso. Zinsanja zotsika mphamvu zimagwiritsidwa ntchito kwambiri popangira mizere yamagetsi otsika, okhala ndi nsanja zazitali nthawi zambiri zosachepera 10 metres; nsanja zokhala ndi mphamvu zambiri zimagwiritsidwa ntchito popanga mizere yothamanga kwambiri, yotalika nthawi zambiri kuposa 30 metres; Masanja a UHV amagwiritsidwa ntchito popanga mizere yotumizira ma voliyumu apamwamba kwambiri, omwe nthawi zambiri amakhala opitilira 50 metres. Kuphatikiza apo, malinga ndi mawonekedwe a nsanjayo, nsanja zotumizira zitha kugawidwa m'makona azitsulo, nsanja zachitsulo zamachubu ndi nsanja zolimba za konkriti.Ngongole zitsulondi zitsulo chubu nsanja zimagwiritsa ntchito kwambiri mizere kufala voteji, pamene analimbitsa konkire nsanja zimagwiritsa ntchito mizere sing'anga ndi otsika-voltage kugawa.
Ndi kupezedwa ndi kugwiritsiridwa ntchito kwa magetsi, kuyambira chakumapeto kwa zaka za zana la 19 mpaka kuchiyambi kwa zaka za zana la 20, magetsi anayamba kugwiritsidwa ntchito mofala kuunikira ndi mphamvu, motero kupangitsa kufunika kwa nsanja zotumizira. Towers za nthawi imeneyi zinali zomangira zosavuta, zambiri zopangidwa ndi matabwa ndi zitsulo, ndipo zinkagwiritsidwa ntchito kuthandizira mizere yamagetsi oyambirira. M'zaka za m'ma 1920, ndikukula kosalekeza kwa gridi yamagetsi ndi kupititsa patsogolo kwa teknoloji yotumizira mphamvu, zida zansanja zovuta kwambiri zidawonekera, monga nsanja zazitsulo zazitsulo. Nyumbazi zinayamba kutengera kamangidwe kameneka kuti zigwirizane ndi madera komanso nyengo. Pambuyo pa Nkhondo Yachiwiri Yapadziko Lonse, ntchito ya nsanja zotumizira mauthenga idalimbikitsidwanso chifukwa chofuna kumanganso zida zowonongeka komanso kuchuluka kwa magetsi. Panthawi imeneyi, mapangidwe a nsanja ndi njira zopangira zida zakhala bwino kwambiri, ndi zitsulo zamphamvu kwambiri komanso njira zotsutsa zowonongeka. Kuphatikiza apo, mitundu yosiyanasiyana ya nsanja zopatsirana zawonjezeka kuti zikwaniritse zosowa zamitundu yosiyanasiyana yamagetsi ndi malo okhala.
M'zaka za m'ma 1980, ndi chitukuko chaukadaulo wamakompyuta, mapangidwe ndi kusanthula kwa nsanja zotumizira zidayamba kusinthidwa kukhala digito, kukonza magwiridwe antchito komanso kulondola. Kuphatikiza apo, ndikupita patsogolo kwa kudalirana kwa mayiko, makampani opanga ma transmission tower ayambanso kufalikira padziko lonse lapansi, ndipo mabizinesi amitundu yosiyanasiyana ndi ma projekiti amgwirizano ndizofala. Kulowa m'zaka za zana la 21, makampani opanga ma transmission tower akupitiliza kukumana ndi zovuta komanso mwayi pazatsopano zaukadaulo. Kugwiritsa ntchito zinthu zatsopano monga ma aluminiyamu aloyi ndi zida zophatikizika, komanso kugwiritsa ntchito ma drones ndi njira zowunikira mwanzeru, zathandizira kwambiri magwiridwe antchito ndi magwiridwe antchito a nsanja zotumizira. Panthawi imodzimodziyo, pamene chidziwitso cha chilengedwe cha padziko lonse chikuwonjezeka, makampaniwa akufufuzanso njira zopangira zachilengedwe komanso zopangira zachilengedwe, monga kugwiritsa ntchito zipangizo zobwezeretsedwa komanso kuchepetsa zotsatira za zomangamanga pa chilengedwe.
Mafakitale apamwamba ansanja zotumiziramakamaka zikuphatikizapo kupanga zitsulo, kupanga zipangizo zomangira, ndi kupanga makina. Makampani opanga zitsulo amapereka zipangizo zosiyanasiyana zazitsulo zomwe zimafunikira pa nsanja zotumizira, kuphatikizapo zitsulo za ngodya, mapaipi achitsulo, ndi rebar; makampani opanga zida zomangira amapereka konkire, simenti ndi zipangizo zina; ndipo makampani opanga makina amapereka zida zosiyanasiyana zomangira ndi zida zokonzera. Mlingo waukadaulo ndi mtundu wazinthu zamafakitale okwera kumtunda zimakhudza kwambiri moyo ndi moyo wa nsanja zotumizira.
Kuchokera pamawonekedwe a mapulogalamu otsika,nsanja zotumiziraamagwiritsidwa ntchito kwambiri popereka mphamvu ndi kugawa. Pomwe kugwiritsidwa ntchito kwa mphamvu zongowonjezwdwanso monga dzuwa, mphepo, ndi magetsi ang'onoang'ono akuchulukirachulukira, momwemonso kufunikira kwa ma microgrid, ndikupititsa patsogolo kukula kwa msika wamagetsi otumizira. Izi zakhala ndi zotsatira zabwino pamsika wa transmission tower. Malinga ndi ziwerengero, pofika chaka cha 2022, mtengo wamsika wamsika wapadziko lonse lapansi udzafika pafupifupi $28.19 biliyoni, chiwonjezeko cha 6.4% kuchokera chaka chatha. China yapita patsogolo kwambiri pakupanga ma gridi anzeru komanso kugwiritsa ntchito ukadaulo wamagetsi opitilira muyeso, zomwe sizinangowonjezera kukula kwa msika wapanyumba, komanso zakhudza kukula kwa msika kudera lonse la Asia-Pacific. Zotsatira zake, dera la Asia-Pacific lakhala msika waukulu kwambiri padziko lonse lapansi wogula nsanja zotumizira, zomwe zikuwerengera pafupifupi theka la gawo la msika, pafupifupi 47.2%. Kutsatiridwa ndi misika yaku Europe ndi North America, yowerengera 15.1% ndi 20.3% motsatana.
Tikuyembekezera zam'tsogolo, ndi ndalama zomwe zikupitilira pakukonzanso gridi yamagetsi ndi kusinthika kwamakono, komanso kukwera kwamagetsi okhazikika komanso otetezeka, msika wa nsanja zotumizira ukuyembekezeka kupitiliza kukula. Zinthu izi zikuwonetsa kuti makampani opanga ma transmission tower ali ndi tsogolo labwino ndipo apitiliza kuchita bwino padziko lonse lapansi. Mu 2022, makampani aku China otumiza nsanja afika kukula kwakukulu, ndi msika wokwanira pafupifupi 59.52 biliyoni yuan, chiwonjezeko cha 8.6% kuposa chaka chatha. Kufunika kwamkati kwa msika waku China wa transmission tower makamaka kumakhala ndi magawo awiri: kumanga mizere yatsopano ndikukonza ndi kukweza zida zomwe zilipo. Pakali pano, msika wapakhomo ukulamulidwa ndi kufunikira kwa zomangamanga zatsopano; komabe, m'mene zaka zachitukuko ndi kufunikira kwa kukonzanso zikuchulukirachulukira, gawo la msika la kukonza nsanja zakale ndikusintha pang'onopang'ono likukwera. Zambiri mu 2022 zikuwonetsa kuti gawo lamsika lazokonza ndikusintha ntchito m'malo ogulitsa nsanja zam'dziko langa lafika 23.2%. Mchitidwewu ukuwonetsa kufunikira kopititsira patsogolo kukweza kwa gridi yamagetsi apanyumba komanso kutsindika kowonjezereka pakuwonetsetsa kudalirika komanso kuchita bwino kwa kufalitsa mphamvu. Ndi njira zomwe boma la China likulimbikitsa zosintha mphamvu zamagetsi komanso kumanga gululi mwanzeru, makampani opanga ma transmission tower akuyembekezeka kupitilizabe kukula m'zaka zingapo zikubwerazi.
