Bophara ba lesoba: E sebelisoa bakeng sa ho thaepa liboutu/lithakhisa ho tsamaisana le lintlha tsa bolt tsa likarolo tse hokahaneng. Mefuta e tloaelehileng ke M8, M10, M12, M14, M16, M18, le M20. Hole center distance: Sebaka se pakeng tsa litsi tsa masoba a mabeli a bapileng. E tlameha ho lumellana le boemo ba lesoba le ntseng le phahama la likarolo tse hokahaneng. Boholo bo tloaelehileng ke 50mm, 60mm, 80mm, le 100mm.
Litlhaloso tsa thepa li khethoa ke ts'ebetso e hlokehang ea poleiti ea joko ea galvanized triangular:
K'habone e tloaelehileng: Q235, e loketseng meroalo e bobebe ho isa bohareng le tikoloho ntle le kutu e khethehileng, e nang le litšenyehelo tse tlase;
Holimo-matla a tšepe ea carbon: Q345, e loketseng meroalo e boima le meroalo e phahameng{2}}ea ho jara lisebelisoa, ka matla a fetang 30% ho feta Q235;
Tšepe e sa hloekang: 304/316 tšepe e sa hloekang, e entsoeng ka masenke a eketsehileng (kapa a feteletsoeng), e loketseng libaka tse lebōpong la leoatle le tse senyang lik'hemik'hale, empa ka litšenyehelo tse phahameng.
Tekanyetso ea galvanizing e ama ka kotloloho ho hanyetsa kutu le bophelo ba ts'ebeletso. Ho chesa-dip galvanizing: E lumellana le GB/T 13912-2022 le ASTM A123, e nang le botenya ba zinc E kholo ho feta kapa e lekanang le 65μm (ts'ebetso e tloaelehileng) le E kholo ho feta kapa e lekanang le 85μm (tikoloho e senyang), e netefatsa sebaka se ts'oanang ntle le libaka tse fositseng. Electro-galvanizing: Zinc layer botenya ba 10~20μm, e loketseng tikoloho ea ka tlung le e omileng, ka theko e tlase ho feta ea hot-dip galvanizing, empa ho senyeha ho fokolang.
Litlhaloso tsa Bokhoni ba Mojaro:
Mosebetsi oa Leseli: E lekantsoe mojaro Ka tlase kapa ho lekana le 5kN;
Mosebetsi o Bohareng: 5kN ~ 20kN;
Boikarabelo bo boima: 20kN ~ 50kN;
Boima bo Eketsehileng: E kholo ho feta kapa e lekanang le 50kN;
Maemong a mangata, lipoleiti tsa joko tsa galvanized triangular li etsoa ho latela litlhoko tsa bareki. Ha u itloaetsa, litlhophiso tse kang{1}}litlhoko tsa ho beleha, litekanyo tsa likarolo tse hokelang, le tikoloho ea ts'ebeliso li tlameha ho fanoa ho netefatsa hore li lumellana le maemo a ts'ebetso.
Lefapha la motlakase le hloka litlhokahalo tse phahameng haholo bakeng sa-ho mamella ho tsitsa le boemo ba leholimo ba likarolo. Lipoleiti tsa joko tse nang le galvanized triangular, e le likarolo tsa mantlha tsa "connecting hardware," li loketse litlhoko tsa phetisetso ea lithapo tse phahameng-tse phahameng/tlaase{3}} tsa motlakase.
Maemo a Kopo: Ho hokela likhoele tsa insulator, li-conductor, li-crossarms tsa tora, kapa ho lokisa li-conductors tsa shunt le li-jumpers;
Litlhoko tsa Bohlokoa: Ho jara boima ba conductor, moea o matla, le lehloa le leqhoa; e hanana le pula le kutu ea UV libakeng tse kantle;
Tšebeliso e Tloaelehileng: Ho kopanya likhoele tsa insulator (likoti tse 2) le li-crossarms tsa tora (sekoti se le seng) ka likoti tse tharo tsa poleiti ea joko, ho arolelana tsitsipano ea conductor ka ho lekana le ho thibela khatello e sa lekaneng le ho senyeha ha li-insulators; e sebelisetsoang ho arola li-conductors (2~4 splits) ho 220kV le holimo{5}}lithapo tsa motlakase e le lintlheng tsa khokahanyo ea makala ho tsamaisa tsitsipano ea conductor.
Litlhaloso tse Loketseng: Boima bo Bohareng/Bo boima-mosebetsi (botenya ba poleiti 8~14mm, bophara ba lesoba M16~M20, boima ba moroalo 10~30kN), ho chesa-dip galvanized (e lumellana le GB/T 13912-2022).
