Chipinda cha goli ndi cholumikizira chapakati pamakina ndi gawo logawa katundu mu mizere yotumizira, ma substations, ndi makina oyenerera magetsi. Nthawi zambiri ndi mbale yachitsulo yosalala yokhala ndi mabowo angapo. Ntchito yake yayikulu ndikulumikiza ma insulators, U{2}}mphete zooneka ngati zoboola pakati, ma bolts, tension clamps, ndi zigawo zina zotsatizana kapena zofananira, kugawa kofanana kwa kokitala, katundu wamphepo, ndi katundu wa icing, kuwonetsetsa kukhazikika kwamakina amagetsi pansi pazovuta zogwirira ntchito. Mwachidule, zili ngati "adaputala yapadziko lonse" pamagetsi-kulumikiza chopingasa mbali imodzi ndi chingwe cha insulator mbali inayo, kugawa katundu wa conductor pakati, kupangitsa kuti ikhale "stress{5}}bearing hub" yofunikira kwambiri-voltage/ultra-high-
Chitsulo{0}chochepa cha carbon
Chitsulo chochepa{{0}chokhala ndi mpweya wa kaboni wocheperako{0}chikutanthauza chitsulo wamba chokhala ndi mpweya Wochepera kapena wofanana ndi 0.25%. Pakhomo, Q235 (zokolola mphamvu 235MPa) imagwiritsidwa ntchito nthawi zambiri, pomwe padziko lonse lapansi imagwirizana ndi SS400 ndi A36. Ndizinthu zofunikira kwambiri zachitsulo m'munda wa mafakitale. Ndi mphamvu yolimba ya 370-500MPa, imatha kupirira kunyamula mizere wamba, sipunduka mosavuta, komanso sisweka popinda ndi kupondaponda. Ndizoyenera malo ovuta a dzenje ndi mapangidwe osakhazikika. Kudula, kubowola, kuboola, kukhomerera, ndi kupindana kotentha n'kosavuta, zomwe zimapangitsa kuti azipanga bwino kwambiri, ziwongolere pang'ono, komanso mtengo wake-wotsika pang'ono{17}}wosintha makonda. Zochitika zazikulu zogwiritsa ntchito ma 10kV, 35kV, ndi 110kV otumizirana mameseji wamba, madera wamba a m'tauni, ma bay insulator, malo okwera mabasi, ma hardware omwe{18}osachita dzimbiri,{19}m'madera{19}}a m'mphepete mwa nyanja,{21}anthu omwe alibe mpweya,magawo olemera kwambiri. Ndi pulojekiti yofunika kwambiri pama projekiti omwe amaika patsogolo kutsika mtengo.
Hot-dip galvanized high-chitsulo champhamvu cha carbon
Ndilo mbale yolemetsa kwambiri-yokhala ndi mpweya wa 0.18%-0.22%. Kuwonjezedwa kwa tinthu tating'ono ta Mn ndi Si kumalimbitsa mphamvu zake, zomwe zimapangitsa kuti ikhale yochepa kwambiri kuposa -zitsulo za carbon. Simakonda kupindika komanso kusweka polemedwa kwambiri, simatopa kwambiri, ndipo simakonda kusweka pogwedezeka-kwanthawi yaitali. Komanso kumatentha-dip galvanized, kumapereka moyo woteteza dzimbiri kwa zaka 20-25. Ndiwolimba kuposa chitsulo chochepa cha carbon, koma mtengo wake ndi 20% -40% kuposa Q235. Ilinso ndi kuuma kwakukulu, komwe kumafunikira nkhungu zapadera pobowola ndi kukhomerera, zomwe zimapangitsa kuti pakhale kugwiritsa ntchito mphamvu pang'ono. Mapulogalamuwa akuphatikiza mizere ya gridi ya 220kV, 400kV, ndi 500kV, malo otalikirapo, madera okhala ndi icing yolemera, ndi mphepo yamkuntho, mbale zoyikira mabasi apamwamba m'malo ang'onoang'ono, zida zolumikizira masiteshoni osinthira, ndi mizere yotumizira mphamvu yamphepo.
(3) Aloyi structural chitsulo
Alloy structural steel Yoke Plate imagwiritsidwa ntchito popanga -voltage yapamwamba/yowonjezera{{1}magetsi okwera kwambiri komanso olemetsa kwambiri-ma pulogalamu. Chitsulo chopangidwa ndi alloy chimapangidwa powonjezera zinthu monga Cr, Mo, Ni, ndi V ku chitsulo cha carbon, ndiyeno panga ndi kutentha-kuchikonza kuti chikhale cholimba kwambiri-cholimba kwambiri. Magiredi oyimilira akuphatikiza 40Cr ndi 35CrMo, za -zolemera kwambiri{10}}zitsulo zokhala ndi zitsulo. Mphamvu ya alloy structural steel ndi 900-1200MPa, 2-3 kuŵirikiza katatu kuposa{17}} carbon steel, ndipo imatha kupirira katundu wopitirira 100kN, kupangitsa kuti ikhale "pamwamba{18}}pa{19}}voltage{25} yokwera kwambiri{25} Simakonda kusweka chifukwa cha-kugwedezeka kwa mphepo kwa nthawi yaitali komanso kusiyana kwa kutentha (-madigiri 40 ~{23}}), imakhala yolimba kwambiri, ndipo siwonongeka mosavuta madzi oundana akatsika kapena ma conductor akuthamanga. Hot-dip galvanizing and passivation treatment, kapena Dacromet coating, imapereka moyo woteteza dzimbiri kwa zaka 25-30, zomwe zimapangitsa kuti zikhale zoyenera m'malo ovuta kwambiri. Alloy structural steel Goli Plates amagwiritsidwa ntchito makamaka mu mizere ya ± 800kV UHVDC ndi 1000kV UHVAC, komanso mbale zolumikizira zolumikizira zingwe zitatu kapena zinayi ndi mbale zazikulu zamatani.
(4) aluminiyamu aloyi
Ma aluminiyamu aloyi amapangidwa ndi aluminiyamu, ndi zinthu zowonjezera monga Mg, Si, ndi Cu. Magiredi omwe amagwiritsidwa ntchito kwambiri ndi 6061 (T6 heat treatment) ndi 6063. Kuchuluka kwawo ndi chimodzi-gawo limodzi mwa magawo atatu a chitsulo, kuwapanga kukhala zitsulo zopepuka. Ndi kachulukidwe ka 2.7 g/cm³ (zitsulo 7.85 g/cm³), amachepetsa kulemera ndi 60% pamiyeso yofanana. Kuyika-pamwamba kwambiri (tower work) sikufuna zida zazikulu ndipo kumatha kuchitidwa pamanja, kuchepetsa chiopsezo cha kugwa. Filimu yowundana ya aluminiyamu imapanga pamwamba pa aluminiyamu, yopatula mpweya ndi chinyezi, zomwe zimachotsa kufunika kotentha-dip galvanizing. Amakhala ndi moyo kwa zaka 20-25 m'madera a m'mphepete mwa nyanja, m'madera opangira mankhwala, ndi{19}}momwe muli chinyezi chambiri, popanda dzimbiri. Yoke Plate imeneyi imagwiritsidwa ntchito makamaka mumizere ya 10kV ndi 35kV low{{20}voltage yogawa magetsi, yoyenera kwa nthawi zazifupi, malo opanda icing, ndi malo wamba amatawuni.
(5)Chitsulo chosapanga dzimbiri
Chitsulo chosapanga dzimbiri chili ndi Greater kuposa kapena yofanana ndi 10.5% chromium. 304 (18-8 stainless steel, 18% chromium, 8% nickel) ndi wamba-giredi yacholinga, pomwe 316 (yokhala ndi 2%-3% molybdenum resistance, spray it super alkaline) imapereka mchere high-end anti-corrosion metal. 304 imalimbana ndi dzimbiri wamba, pamene 316 imagonjetsedwa ndi kupopera mchere, ma acid, alkalis, ndi madzi a m'nyanja. Ili ndi moyo wautumiki wazaka zopitilira 30 m'malo am'mphepete mwa nyanja, m'mafakitale am'madzi, ndi nsanja zakunyanja, ndipo sizichita dzimbiri. Kulimba kwake ndi 510-620MPa, kufupi ndi Q235, kumapereka mphamvu komanso kusatopa, kupangitsa kuti ikhale yoyenera kunyamula katundu wapakati komanso malo ogwedera. Ili ndi-zonyezimira zitsulo zotalika, sizifuna zokutira, ndipo ndi yosavuta kupukuta mafuta ndi fumbi, kuti ikhale yoyenera malo aukhondo ndi mizere yakunja. Imagwira ntchito pamafamu amphepo am'mphepete mwa nyanja, mizere yodutsa m'mphepete mwa nyanja, malo osungiramo mankhwala opangira mankhwala, makina opangira magetsi ochotsa madzi a m'nyanja, mapulatifomu akunyanja, ndi madoko opangira magetsi. Kuti mukhale ndi nthawi yayitali ndi madzi a m'nyanja ndi mchere wamchere, zitsulo zosapanga dzimbiri ndi njira yokhayo yothetsera nthawi yaitali.
Goli Plate lingawoneke ngati losavuta, koma kwenikweni, "zinthu zimatsimikizira moyo wautali, ndipo luso limatsimikizira chitetezo." Kusankha zinthu zoyenera kumatha kukonza zotengera magetsi{1}kwaulere kwa zaka 20-30, kupewa kuzima kwa magetsi; kusankha zinthu zolakwika kungayambitse dzimbiri ndikusintha zaka 1-2 zilizonse, kapena kusweka komwe kumabweretsa ngozi zazikulu zachitetezo.
