Transmission line tower ke meaho e melelele e sebelisetsoang phetiso ea matla a motlakase. Litšobotsi tsa bona tsa sebopeho li thehiloe haholo-holo mefuteng e fapaneng ea meaho ea truss ea sebaka. Litho tsa litora tsena li entsoe ka tšepe e le 'ngoe ea equilateral angle kapa tšepe e kopantsoeng ea angle. Lisebelisoa tse sebelisoang hangata ke Q235 (A3F) le Q345 (16Mn).
Likamano pakeng tsa litho li entsoe ka liboutu tse mahoashe, tse kopanyang likarolo ka matla a ho kuta. Tora eohle e hahiloe ka tšepe ea mahlakoreng, lipoleiti tsa tšepe tse kopanyang, le liboutu. Likarolo tse ling, joalo ka motheo oa tora, li hokahanngoa ho tsoa lipoleiting tse 'maloa tsa tšepe ho etsa yuniti e kopaneng. Moralo ona o lumella hore ho be le galvanization ea hot-dip bakeng sa ts'ireletso ea kutu, ho etsa hore lipalangoang le kopano ea kaho e be bonolo haholo.
Litora tsa transmission line li ka aroloa ho latela sebopeho le sepheo sa tsona. Ka kakaretso, li arotsoe ka libōpeho tse hlano: sebopeho sa kopi, sa hlooho ea katse, sebopeho se otlolohileng, sebopeho sa cantilever, le sebopeho sa moqomo. Ho ipapisitsoe le ts'ebetso ea bona, li ka aroloa ka litora tsa tsitsipano, litora tse otlolohileng, litora tsa mahlakoreng, litora tse feto-fetohang (bakeng sa ho fetola boemo ba li-conductor), litora tsa ho qetela le litora tse tšelang.
Straight-Line Towers: Tsena li sebelisoa likarolong tse otlolohileng tsa mehala ea phetisetso.
Tension Towers: Tsena li kentsoe ho sebetsana le tsitsipano ho li-conductor.
Angle Towers: Tsena li behiloe libakeng tseo mohala oa phetisetso o fetolang tsela.
Crossing Towers: Litora tse phahameng li behiloe ka mahlakoreng a mabeli a ntho leha e le efe e tšelang ho netefatsa hore ho na le tumello.
Phase-Changing Towers: Tsena li kenngoa ka linako tse ling ho leka-lekanya ho se sebetse ha li-conductor tse tharo.
Terminal Towers: Tsena li fumaneha libakeng tsa khokahano lipakeng tsa mehala ea phetisetso le liteishene tse nyane.

Litora tsa phetiso li entsoe ka lipalo tsa konkreite tse matlafalitsoeng le litora tsa tšepe. Li ka boela tsa aroloa ka litora tse iphelisang le litora tse nang le banna ho latela botsitso ba tsona.
Ho tsoa methapong e teng ea phetisetso ea China, ho tloaelehile ho sebelisa litora tsa tšepe bakeng sa maemo a motlakase a kaholimo ho 110kV, ha lipalo tsa konkreite tse matlafalitsoeng hangata li sebelisoa bakeng sa maemo a motlakase a ka tlase ho 66kV. Lithapo tsa Guy li sebelisoa ho leka-lekanya meroalo e ka morao le tsitsipano ho li-conductor, ho fokotsa nako ea ho kobeha botlaaseng ba tora. Tšebeliso ena ea lithapo tsa motlakase e ka fokotsa tšebeliso ea thepa le ho theola litšenyehelo tse akaretsang tsa mohala oa phetiso. Litora tsa Guyed li atile haholo libakeng tse bataletseng.
Khetho ea mofuta oa tora le sebopeho li lokela ho ipapisa le lipalo tse fihlelang litlhoko tsa motlakase ha ho ntse ho nahanoa boemo ba motlakase, palo ea lipotoloho, sebaka le maemo a jeoloji. Ho bohlokoa ho khetha foromo ea tora e loketseng morero o itseng, qetellong u khethe moralo o tsoetseng pele ka botekgeniki le o loketseng moruo ka tlhahlobo ea papiso.
Lithapo tsa phetiso li ka hlophisoa ho ipapisitsoe le mekhoa ea tsona ea ho kenya lithapo tsa phetiso e holimo, lithapo tsa phetiso ea lithapo tsa motlakase, le likhoele tse kentsoeng ka tšepe tse kentsoeng ka khase.
Lithapo tsa Phetiso e Ntle: Hangata li sebelisa li-conductors tse se nang letho, tse tšehelitsoeng ke litora tse fatše, 'me li-conductors li emisitsoe litora li sebelisa li-insulator.
Lithapo Tse Fetisang Lithapo Tsa Motlakase: Hangata li patoa ka tlas'a lefatše kapa li behoa ka har'a lithapo kapa likotopo, tse nang le likhoele hammoho le lisebelisoa, lisebelisoa tse tlatselletsang le lisebelisoa tse kentsoeng likhoeleng.
Mehala ea Ts'ebetso ea Metal-Enclosed Transmission Lines (GIL): Mokhoa ona o sebelisa lithupa tsa tšepe tse tsamaisang litšepe bakeng sa ho fetisoa, tse koaletsoeng ka ho feletseng ka har'a khetla ea tšepe e thehiloeng fatše. E sebelisa khase e hatelletsoeng (hangata SF6) bakeng sa ho kenya letsoho, ho netefatsa botsitso le polokeho nakong ea phetisetso ea hajoale.
Ka lebaka la litšenyehelo tse phahameng tsa lithapo le GIL, mehala e mengata ea phetiso hajoale e sebelisa mela e holimo.
Lithapo tsa phetisetso le tsona li ka aroloa ka maemo a motlakase ho ea ho li-voltage tse phahameng, lithapo tse phahameng haholo le lithapo tsa motlakase tse phahameng haholo. Chaena, maemo a motlakase a likhoele tsa phetiso a kenyelletsa: 35kV, 66kV, 110kV, 220kV, 330kV, 500kV, 750kV, 1000kV, ±500kV, ±660kV, ±800kV0, le ±10kV ±10.
Ho ipapisitsoe le mofuta oa phetiso ea hajoale, mela e ka aroloa ka mela ea AC le DC:
AC Lines:
Matla a Phahameng a Matla (HV) Lines: 35 ~ 220kV
Matla a Eketsehileng a Matla a Phahameng (EHV): 330 ~ 750kV
Ultra High Voltage (UHV) Lines: Ka holimo ho 750kV
DC Lines:
