Umbhoshongo wokudlulisa (futhi i-pylon kagesi, i-hydro tower e-Canada, kanye ne-pylon eBrithani) isakhiwo eside, ngokuvamile umbhoshongo we-lattice owenziwe ngensimbi osetshenziselwa ukusekela intambo yamandla engaphezulu. Kumagridi kagesi, imibhoshongo yokudlulisa ithwala izintambo zikagesi ezinamandla amakhulu ezithutha amandla kagesi omningi ukusuka eziteshini ezikhiqizayo kuya eziteshini zikagesi, lapho ugesi uthunyelwa khona kubathengi; ngaphezu kwalokho, izigxobo ezisetshenziswayo zisetshenziselwa ukusekela izintambo zama-voltage amancane zokudluliswa nokusabalalisa ezithutha ugesi usuka eziteshini ezincane uye kumakhasimende kagesi.

Kunezigaba ezine zemibhoshongo edluliswayo: (i) umbhoshongo omisiwe, (ii) umbhoshongo ogcina ufile, (iii) umbhoshongo odonsa kanzima, kanye (iv) nombhoshongo oguquguqukayo.[1] Ubude bemibhoshongo yokudlulisela isuka ku-15 kuya ku-55 m (49 kuya ku-180 ft);[1] ephakeme kakhulu imibhoshongo engu-380 m (1,247 ft) ye-2,656 m (8,714 ft) ye-Jintang-Cezi Overhead Powerline Link , phakathi kweziqhingi iJintang neCezi esifundazweni saseZhejiang, eChina. Isikhathi eside kakhulu sokuwela ugesi ngamanzi yi-Ameralik Span yentambo yamandla ewela i-Ameralik fjord, enobude obungu-5,376 m (17,638 ft). Kudingeka imibhoshongo eminingi yokudlulisela ukunciphisa ukuguquguquka kwesimo sezulu, ngakho-ke ngeminyaka yama-2020 imibhoshongo yokudlulisa yaba yinto ebalulekile kwezepolitiki.

Imibhoshongo yolayini wokudlulisa imvamisa ihlukaniswa ngokwesimo, okuhlanganisa uhlobo lwengilazi, uhlobo lwekhanda lekati, uhlobo olungaphezulu, uhlobo olomile kanye nohlobo lwebhakede. Ngokwemisebenzi yayo, kukhona imibhoshongo yolayini wokudlulisa umfutho, imibhoshongo yolayini wokuhambisa u-suspension, imibhoshongo yolayini wokuhambisa ekhoneni, imibhoshongo yolayini wokuhambisa ekhoneni letheminali (imibhoshongo efile), imibhoshongo ewela imifula, njll.
