- ⦁ Ho ba le MATLA ho etsa mesebetsi ea rona le ho fana ka litšebeletso ho bareki ba ka hare le ba kantle.
Tora ea Phetiso ea Matla
Tora ea phetiso kapa tora ea matla (pylon ea motlakase kapa pylon ea motlakase United Kingdom, Canada le likarolo tsa Europe) ke mohaho o molelele, hangata e le tora ea tšepe ea tšepe, e sebelisetsoang ho tšehetsa mohala oa motlakase o ka holimo.
Li sebelisoa mecheng ea matla a phahameng a AC le DC, 'me li na le libopeho le boholo bo fapaneng. Bophahamo bo tloaelehileng bo tloha ho 15 ho isa ho 55 m (49 ho isa ho 180 ft), leha tse telele ka ho fetesisa ke litora tsa 370 m (1,214 ft) tsa 2,700 m (8,858 ft) span ea Zhoushan Island Overhead Powerline Tie. Ntle le tšepe, lisebelisoa tse ling li ka sebelisoa, ho akarelletsa le konkreite le lehong.
Angle-steel tower, tora e tloaelehileng ea quadrangular truss communication tora, e sebelisang Q345B tšepe ea boleng bo holimo e le thepa ea 'mele ea tora e kholo, sebopeho se thata, deformation e nyane; angle steel splicing connection, likarolo tse bobebe bo bobebe, tora e ka tsamaisoa ka letsoho mme ea kenngoa ka theko e tlase. Ho ka ba le lisebelisoa tse ka holimo tse 6 tsa sethala, sethala ka seng se tšehetsa li-antenna tse 6.
