Transmission towers ua lub hauv paus tseem ceeb ntawm lub zog xa hluav taws xob, thiab lawv cov evolution tsom mus rau kev nce qib ntawm kev siv hluav taws xob thoob ntiaj teb. Nyob rau hauv lub xyoo pua puv 19, lub invention ntawm lub teeb hluav taws xob teeb ua rau ib tug ntse surge nyob rau hauv kev xav tau hluav taws xob kev lag luam, tsim ib tug ceev kev lag luam -wide kev sib tw kom paub npaum li cas ntev - nyob deb zog kis tau tus mob, uas cim lub hauv paus chiv keeb ntawm lub kis tau tus mob ntauwd kev lag luam. Lub ntiaj teb thawj qhov chaw DC fais fab kev lag luam tau muab tso rau hauv kev ua haujlwm hauv xyoo 1882, tab sis nws tseem ua tsis tau raws li qhov kev xav tau ntawm cov khoom siv hluav taws xob. Nws tsis yog txog xyoo 1891 uas lub ntiaj teb thawj qhov ntev - deb AC kis tau tus mob kab, ncab 175 kilometers nrog ib tug voltage ntawm 15,000 volts, tau tsim nyob rau hauv lub teb chaws Yelemees. Qhov kev rhuav tshem no tshem tawm cov kev cuam tshuam loj rau kev xa hluav taws xob thiab sawv ua qhov tseem ceeb hauv keeb kwm ntawm kev xa hluav taws xob. Thaum pib ntawm lub xyoo pua 20th, high{15}}kev ua tau zoo steel lattice towers maj mam hloov cov khoom siv ntoo. Kev khav theeb lub teeb tsis tau siab - lub zog tsim qauv, zoo heev tiv taus cua, daus thiab corrosion, nrog rau kev pab cuam lub neej ntev, lawv tau dhau los ua cov chaw txhawb nqa rau siab -voltage fais fab kis. Tshaj li ib puas xyoo ntawm kev tsim kho thev naus laus zis thiab kev ua kom zoo dua qub, kev siv cov khoom siv hlau tshiab thiab cov txheej txheem kev tsim kho siab heev tau txhim kho kev ruaj ntseg, tus nqi -kev ua tau zoo thiab kev ua tau zoo ntawm cov xaim hluav taws xob.
Niaj hnub no, kev lag luam tau tsim cov khoom lag luam dav dav. Kev faib tawm los ntawm qib voltage, struts thiab kis tau tus mob, mainstream ntauwd hom muaj xws li ncua kev kawm ntawv pej thuam, tension towers thiab tuag-end towers, tag nrho catering rau ntau yam fais fab engineering tej yaam num npog nruab nrab-voltage 330kV kis tau tus mob thiab siab-voltage kis tau tus mob li ntawm 110kV. 75. Tsav los ntawm kev nthuav dav sai ntawm cua, hnub ci thiab lwm yam kev lag luam tshiab zog, nrog rau kev nrov ntawm cov thev naus laus zis tshiab xws li siab -voltage direct tam sim no (HVDC) kis, kev ua lag luam tau nce ntau dua qhov yuav tsum tau ua rau kev hloov pauv thiab kev ruaj ntseg ntawm lub zog xa hluav taws xob. Tam sim no, kev lag luam ntauwd kis tau tus mob tau hloov pauv thiab hloov kho mus rau qhov tsim qauv hnyav, kev ua haujlwm siab dua thiab eco-kev phooj ywg, ua tau raws li qhov xav tau ntawm kev tsim hluav taws xob tshiab thiab tso lub hauv paus ruaj khov rau ntev - nrug, loj - muaj peev xwm xa hluav taws xob thoob ntiaj teb.
