The kukangana achepetsa ndi mtundu umodzi wa zovekera limodzi mavuto hardware, zimagwiritsa ntchito pa mizere pamwamba kufala kapena mizere yogawa.Chotchinga chotchinga chimatchedwanso dead end strain clamp kapena quadrant strain clamp, ndi mtundu umodzi wa zingwe zolumikizira.
Chifukwa mawonekedwe a chotchinga champhamvu ali ngati munthu, kotero makasitomala ena amachitcha mtundu wamunthu kapena mtundu wa bawuti.Malinga ndi mainchesi kondakitala, pali mitundu yosiyanasiyana ya bawuti mtundu kukanika achepetsa monga NLL-1, NLL-2, NLL-3, NLL-4.
Gulu la NLL lamtundu wa bawuti wakufa kumapeto thupi lalikulu limapangidwa kuchokera ku aluminiyamu yamphamvu kwambiri yomwe imakwaniritsa zofunikira zamtundu waposachedwa wa BS.
Mtundu wa bawuti wa tension clamp ndioyenera mizere yamlengalenga mpaka 35kv.Jingyoung bawuti yolimba yamtundu wamtundu wa Jingyoung idapangidwa kuti igwiritsidwe ntchito ndi ACSR kapena ma conductor a aluminiyamu onse.
Makasitomala ena amafunsa mndandanda wamtundu wa bawuti wa NLL pamodzi ndi tepi yankhondo kapena ma liner apadera kuti ateteze woyendetsa kuti asawonongeke.Malinga ndi nkhaniyi, pali mndandanda wina wa NLD-1, NLD-2, NLD-3, NLD-4.Mndandanda wa NLD umapangidwa kuchokera kuchitsulo champhamvu chosungunuka.
NLD tension clamp imagwiritsidwa ntchito ndi aluminiyamu-clad steel conductor.Akagwiritsidwa ntchito pa kondakitala wa aluminiyamu, nthawi zambiri amasonkhanitsidwa ndi liners.
Zomwe zili pamwambazi zimangoyambitsidwa gawo lalikulu la chotchinga champhamvu.Pali U bolt, nati, ndi ma washers ofunikira kuti amangirire ma conductor m'matupi amfuti.
Kupanga kwa Clamp
- bolt, mtundu wa quadrant, wokhala ndi ma clevis end woyenerera, omwe amagwiritsidwa ntchito pothetsa aluminiyamu kapena ma aluminium alloy conductors.Maonekedwe akufanana ndi Chithunzi 1 pansipa.
- Ngongole yodziwika bwino ya 60 monga momwe tafotokozera pa Chithunzi 1.
- Thupi lamphamvu kwambiri la aluminium alloy clamp.
- Zitsulo za U-bolts, iliyonse yokhala ndi mtedza wa hex, mawotchi awiri ozungulira, ndi mawotchi awiri a loko.
- Zigawo zonse zachitsulo, kupatula zomwe zimapangidwa ndi chitsulo chosapanga dzimbiri, ziyenera kuviika ngati malata otentha molingana ndi BS EN ISO 1461:2009 kapena ASTM A153/153
- Kusamalira ndi kuteteza ma kondakitala a mizere opanda kanthu okhala ndi ma diameter ofotokozedwa mu Columns 2 ndi kukula kwake kwa waya mu Columns 3 ndi 4 ya Table 1.
- Chiwerengero cha ma U-bolt operekedwa kuti ateteze kondakitala pamalopo chotchinga monga momwe tafotokozera mu Table 1, Columns 5.
- Makulidwe a clevis ndi coupling pin molingana ndi Table 1.
- Kulimba kwamphamvu kopitilira muyeso molingana ndi Gawo 6 la Gulu 1.
- Kulimba mtima kopitilira muyeso kokoka diso kukhala lalikulu kuposa kapena lofanana ndi 60﹪ kulimba kwamphamvu komaliza kwa gulu lonse loletsa.
- Pini yogawanika yopangidwa ndi mkuwa wozizira, mkuwa kapena chitsulo chosapanga dzimbiri iyenera kuperekedwa kuti ateteze pini yolumikizira m'malo mwake.
- Katundu wocheperako wolephereka wa pini yolumikizira amafanana ndi kulimba komaliza kwa gulu lonse la clamp.
- Kumanga kwa clamp kuti kusakhale ndi ming'alu ndi zolakwika zina zowoneka, zopanda m'mphepete komanso ma burrs.Mphepete mwa kutsogolo kwa malo olumikizana pafupi ndi diso lokoka kuti liwotchedwe kuti muchepetse kuwonongeka kwa kondakitala.
