M'zaka zaposachedwa, ntchito yomanga gridi yayikulu ku Southeast Asia, Africa ndi Middle-East ikukulirakulira. Mitundu yambiri ya 110 kV-220 kV imatengera mapangidwe a ma kondakitala awiri kuti apititse patsogolo mphamvu yotumizira. Komabe, ogwira ntchito pang'ono amafotokoza zoopsa zobisika zanthawi yayitali, monga kusamvana kwa ma sub-conductor, ma abrasion am'deralo a hardware ndi kutopa kwamphamvu kwa zopangira zotchingira pansi pakuyenda kwa mphepo. Zolumikizira zachikhalidwe zosalala nthawi zambiri sizitha kuzindikira kuthamangitsidwa koyenera kwa mphamvu yokoka ya mfundo imodzi, zomwe zimakankhira makontrakitala a EPC kuti aziyang'anira kwambiri kapangidwe kazinthu za goli-plate.
Fakitale yathu ya L-1640 ya goli la triangular yapangidwa kuti ikhale yowawa iyi, yokhala ndi kulephera kwadzina komwe kumafika 160 kN. Kutalika konse kwa dzenje ndi 400 mm, utali wowongoka H=100 mm, makulidwe a mbale 18 mm, kulemera kwake ndi 5.8 kg. Mosiyana ndi mbale za makoko akona amakona anayi, imagwiritsa ntchito mphamvu ya apex-ngodya-kulandira mawonekedwe odulira amakona atatu popanda kuwotcherera. Bowo lalikulu lokhala ndi katundu pamwamba limapanga mphamvu yokoka ya mfundo imodzi yochokera ku ma insulator, pomwe mabowo awiri apansi amatulutsa kukanikiza koyenera kwa kuyimitsidwa kwa ma sub-conductors. Mabowo ophatikizika apakatikati amathandizira kwambiri ntchito yolumikizira isanakwane kuti igwire ntchito zokwezera mtunda wautali. Mphepete mwa mabowo onse ndi opindika ndipo ma contour akunja amazunguliridwa mokwanira kuti athetse kupsinjika komwe kumachitika mosavuta pazida zosindikizidwa. Pama projekiti omwe amafunikira nthawi yayitali yoyika, mtundu wokulirapo L-16-100-600 umagawana ma 160 kN makina ofananira, kukulitsa mtunda wapakati wa dzenje mpaka 600 mm, kuphimba zofuna zapadera zolumikizirana ndi zingwe zolemetsa.
Kusankha kwazinthu zosapanga dzimbiri ndi kuwongolera koyenera kokwanira kumayala maziko olimba okhazikika m'munda. Zoyambira zimatengera pepala lachitsulo cha Q235B chotenthetsera cha kaboni. Chitsulo chilichonse chachitsulo chidzadutsa pakuwunikidwa komwe kukubwera, kuphatikiza kulimba kwamphamvu komanso kutsimikizira kulimba kwa zokolola. Chithandizo cha anti-corrosion chapamwamba chimatsata njira yotentha ya dip galvanizing ASTM A123-19. makulidwe okhazikika a zinki-wosanjikiza amawongoleredwa kupitilira 65 μm; kukhuthala kokhuthala Kuposa kapena kofanana ndi 85 μm kutha kuperekedwa kwa madera a m'mphepete mwa nyanja a chifunga cha mchere ndi zoipitsidwa ndi mafakitale. Gulu lililonse lopanga liyenera kumaliza mayeso owononga owononga. Kuchuluka kwenikweni kowononga-kulephera-kuchuluka kwa zitsanzo zomalizidwa kumafika 184 kN, zomwe zimasiya malire achitetezo okwanira kupitilira zomwe zimafunikira 160 kN. Kuyang'ana kwathunthu kumatsimikizira kusinthasintha ndi mbale zosinthira za DB-series, maulalo osinthira a DT-series, P-series parallel hanging plates ndi Z-series angle-angle clevis muzogulitsa zathu, zomwe zimathandiza kuti makina oyimitsa azitha kutumizira makasitomala akunja.
Ndemanga zothandiza kuchokera kumapulojekiti angapo akunja kwa EPC zatsimikizira momwe ntchito yake ikuyendera. Mu pulojekiti imodzi ya 220 kV yodutsa maulendo awiri ku Southeast Asia, makontrakitala amafananiza L-1640 ndi mbale yosinthira DB-21, ulalo wosinthira wa DT-16 ndi P-16100 yolenjekeka yofananira kuti amange kuyimitsidwa kwa ma kondakitala awiri. Pambuyo pa opareshoni ya miyezi 14 pansi pa nyengo yamvula komanso malo akuthamanga kwa conductor pafupipafupi, kuyang'anira malo kumawonetsa kuti palibe zowoneka bwino zovala pamabowo a magoli ndi ma pini ofananira. Kusamvana pakati pa ma sub-conductors awiri kumakhala pansi pa 9.2%, zomwe zimakwaniritsa kuyembekezera kwa polojekiti. Mu projekiti ina yazitsulo zazitsulo zazitsulo, L-1640 yayikidwa kuti igwirizane ndi mawaya apawiri. Poyerekeza ndi dongosolo losavuta la lap-joint, mawonekedwe a katatu amapewa mikangano yachindunji pakati pa zoyikira pawaya komanso amathandizira kuti dongosolo lonse likhale lokhazikika pansi pa mphepo yamphamvu.
Ogula ambiri amasokoneza mbale ya goli ya katatu ndi mbale ya goli lalikulu pakugula zinthu. Ma mbale a goli a Square LF ndiabwino polumikizana ndi ndege zamabowo ambiri, komabe amawonetsa magwiridwe antchito polimbana ndi kupsinjika kwakanthawi kodzutsidwa ndi kuthamanga kwa conductor. Kapangidwe ka L-1640 triangular-geometry imathandizira njira yosinthira mphamvu yamkati, imabalalitsa mphamvu yamphamvu, ndikuchepetsa bwino chiwopsezo cha kutopa kwa hardware. Magulu aumisiri azisankha L-1640 kapena L-16-100-600 molingana ndi kufunikira kwenikweni kwa dzenje-pakatikati pa kujambula kwa nsanja, m'malo mongoweruza potengera kuchuluka kwa katundu.
Pamene ntchito zapadziko lonse lapansi zikuchulukirachulukira, zolumikizira zogawira zoyimiridwa ndi L-1640 zitenga gawo lofunikira kwambiri pakumanga makina otumizira ma bundle-conductor. Fakitale yathu imatha kupereka zikalata zowunikira zonse kuphatikiza satifiketi yoyesa mphero, lipoti la makulidwe a galvanizing-thickness ndi zolemba zamakina zoyeserera zachilolezo komanso kuwunika kwa gulu lachitatu, pakadali pano imavomereza kusintha kwa OEM kwa dzenje ndi makulidwe a mbale pamaoda apadera a EPC.
