Pamakona a zingwe monga zingwe za kuwala, mtundu wa zopangira mphamvu - zotsekera zovuta zimawonedwa nthawi zambiri.Chotchinga chotchinga chimagwiritsidwa ntchito kukonza waya kuti azitha kugwedezeka kwa waya, ndikupachika waya kuzitsulo zoyenerera pa chingwe kapena nsanja.Amagwiritsidwa ntchito kukonza waya kapena woyendetsa mphezi pa chingwe cha insulator yamphamvu ya nsanja yopanda mzere, ndipo imakhala ngati nangula.Waya wachitsulo wa Spiral aluminium-clad steel uli ndi mphamvu zolimba kwambiri, osapanikizika kwambiri, ndipo umagwira ntchito poteteza komanso kuchepetsa kugwedezeka kwa zingwe zowala.
Kutengera momwe zimapangidwira komanso kuyika kwake, zolimbitsa thupi zitha kugawidwa m'magulu awiri:
gulu loyamba: zingwe zomangika zimayenera kupirira zovuta zonse za kondakitala kapena wowongolera mphezi, ndipo mphamvu yogwira yachitsulo sichocheperapo kuposa mtengo wovotera wa woyendetsa kapena wowongolera mphezi.Kukana kwamphamvu kwa 90, koma osati ngati kokondakita.Mtundu woterewu ukhoza kuchotsedwanso waya atayikidwa ndikugwiritsidwa ntchito padera.Ma clamps oterowo amaphatikiza ma bolt-type strain clamps ndi ma wedge-type strain clamps.
Gulu lachiwiri: zingwe zomangika zimagwiritsidwa ntchito ngati ma conductor kuphatikiza kupirira kukakamira kwa ma conductor kapena mphezi.Choncho, chingwe chamtundu woterechi chikayikidwa, sichingathe kugawidwa, ndipo chimatchedwanso chingwe chakufa.Chifukwa ndi kondakitala, kuyika kwa clamp kuyenera kuchitidwa mosamala molingana ndi njira zoyendetsera ntchito.

Kutengera ndikugwiritsa ntchito, choletsa champhamvu chingagawidwe kukhala:

Makhalidwe a strain clamps:
(1) Mphamvu yapamwamba: chingwe chilichonse chimakhala ndi kutalika kokhotakhota kuti zitsimikizire kuti mphamvu yogwira imatha kufika kupitirira 100% ya mphamvu yowonongeka (RBS) ya chingwe;kusinthasintha kwamphamvu: kumatha Kugwirizana ndi zida zosiyanasiyana.The awiri a lalikulu kukoka waya achepetsa ndi chosinthika kukoka waya achepetsa akhoza kufika 1.001 mainchesi (25.4mm, ndiko kuti, malo mtanda ndi 500mm2), amene ndiye chisankho chabwino kwambiri kuthetsa vuto lalikulu kukoka mawaya ku China.
(2) Kukana bwino kwa dzimbiri: zinthuzo ndizofanana ndendende ndi waya wokoka, womwe ungalepheretse dzimbiri la galvanic pakati pa chingwe cha waya ndi waya wokoka.
(3) Kuyika kosavuta: Mitundu yonse yazitsulo zokoka waya zimatha kuyendetsedwa mwachangu komanso mosavuta pamalowo ndi dzanja, popanda zida zapadera, ndipo ntchitoyi imatha kumalizidwa ndi munthu m'modzi.
(4) Ubwino woyika ndi wosavuta kutsimikizira, ndipo kuyika kwa chingwe cha kukoka ndikosavuta kuonetsetsa kusasinthika, palibe maphunziro apadera omwe amafunikira, maso amaliseche amatha kuyang'aniridwa, ndipo mawonekedwe ake ndi osavuta komanso okongola.
Makhalidwe a ADSS strain clamps:
(1) Waya wopotoka wakunja umalumikizidwa mwachindunji ndi nsanjayo kudzera pazolumikizira monga kuyika mphete kuti zinyamule katundu wa mzere.
(2) Skein yamkati imateteza chingwe cha ADSS.Ntchito zazikuluzikulu ndi:
a.Tumizani mogwira mtima mphamvu yopondereza yotalikirapo kugawo lokhala ndi mphamvu ya chingwe cha optical, aramid fiber, kuti mupewe kupsinjika kwambiri pakhungu lakunja la chingwe cha kuwala ndikuwononga.
b.Kufalikira kwa axial tension.
c.Wonjezerani malo okhudzana ndi chingwe cha kuwala, kotero kuti kugawanika kwa nkhawa kumakhala kofanana ndipo palibe malo opanikizika.
(3) Pansi pa malo osapitirira mphamvu ya mphamvu ya mbali ya ADSS optical cable, imakhala ndi mphamvu yowonjezera pa chingwe cha kuwala ndipo imatha kupirira kupanikizika kwakukulu.
(4) Mphamvu yamagetsi ya ADSS optical cable siili yotsika kuposa 95% ya mphamvu yomaliza (UTS) ya chingwe cha kuwala, chomwe chili choyenera kuyika chingwe cha kuwala.

Njira zodzitetezera pakuyika kwazinthu

1. Mukayika zingwe zomangika pamalo okwera, mabawuti ayenera kumangidwa kwathunthu asanamasule chingwe chokokera;
2. Poika zingwe zotchingira mawaya ndi zowongolera mphezi (zingwe zowunikira) pamalo okwera, njira zodalirika ziyenera kuchitidwa kuti mawaya asathe.Miyeso;
3. Malekezero a mawaya odulidwa pa nsanja ayenera kuchepetsedwa ndi zingwe;
4. Mukayika pansi, kuyika kwa ma conductors ndi mawaya oteteza mphezi (zingwe za kuwala) ziyenera kukhala zodalirika, ndipo ntchito yoyimitsa iyenera kuchitidwa ndi akatswiri.
5. Valve yothandizira chitetezo cha pampu ya hydraulic sichidzasinthidwa mosasamala, ndipo valve yothandizira sichidzagwiritsidwa ntchito potsitsa.
