Kusankhidwa kwachikwama chakufaimatsimikiziridwa makamaka molingana ndi mikhalidwe yosiyanasiyana ya oyendetsa chingwe chamagetsi.
Pali mikhalidwe iwiri yofanana.Wopanga zopangira mphamvu akufotokozerani.
1. Kusankhidwa kwa ma clamp strain clamps pamene LGJ ndi LJ conductors amagwiritsidwa ntchito
Mukamagwiritsa ntchito LGJ kapena LJ waya, kuyambirachikwama chakufaimangiriridwa pamtunda wakunja kwa waya ikagwiritsidwa ntchito, chitsanzo cha
Dead end clamp yomwe imagwiritsidwa ntchito iyenera kusankhidwa molingana ndi kukula kwa waya.Mwachitsanzo, waya wa LGJ-185/30 amagwiritsidwa ntchito
mu mzere wamagetsi.Pambuyo kuwerengera, zitha kupezeka kuti m'mimba mwake ndi 18.88mm.Kuchokera pa tebulo pamwambapa, zimadziwika kuti
cholembera chakufa chiyenera kukhala NLL-4, NLL-5 kapena NLD-4.
Kuyenera kudziŵika apa kuti awiri akunja a LGJ waya masamutsidwe kuchokera mtanda gawo la aluminium waya 185mm.
ndi mtanda gawo la zitsulo pachimake 30mm.Sikuti amangowerengedwa ndi mtanda wa aluminiyamu waya 185mm.LGJ mawaya
Zofananira zomwezo zimakhala ndi magawo osiyanasiyana achitsulo ndi ma diameter akunja a waya, kotero chotchingira chakufa chomwe chimagwiritsidwa ntchito pa LGJ.
mawaya amtundu womwewo sakhala ofanana.Ngati ndi waya wa LJ, popeza ilibe pachimake chachitsulo, gawo lodutsa
waya wa aluminiyumu wokhazikika angagwiritsidwe ntchito kuwerengera mbali yakunja ya waya.
Kuphatikiza apo, popeza chotchinga chakufa chimakanikizidwa pamtunda wakunja kwa waya, tikufuna kuti gawo lakunja la LGJ.
kapena waya wa LJ uphimbidwe ndi tepi ya aluminiyamu panthawi yomanga kuti ateteze kuwonongeka kwa waya panthawi ya crimping.
2. Kusankha chingwe cha dead end clamp pamene waya wa insulated wagwiritsidwa ntchito
M’madera amene muli anthu ambiri, amitengo, ndi oipitsidwa, tikugwiritsa ntchito kwambiri mawaya otsekeredwa m’malo mwa mawaya opanda kanthu.Poyerekeza
ndi mawaya opanda kanthu, ili ndi ubwino wa chitetezo chapamwamba ndi kudalirika, kutsika kwa waya, ndi kuchepa kwa waya.Pamene ntchito insulated
mawaya, tiyenera kulabadira mfundo yakuti chotchinga chakufa chimakanikizidwa pamtunda wakunja wa "waya" m'malo mwa
m'mimba mwake wakunja wa "conductor" akagwiritsidwa ntchito, ndiye ayenera kutengera kukula kwa waya m'malo mwa m'mimba mwake.
za "conductor".Kuzungulira kwakunja kwa kondakitala kumagwiritsidwa ntchito kusankha mtundu wamtundu wakufa womwe umagwiritsidwa ntchito.Mwachitsanzo, JKLGYJ
-150/8 chitsulo pachimake cholimbitsa cholumikizira chingwe cha polyethylene insulated mlengalenga chimagwiritsidwa ntchito mu chingwe chamagetsi.Zimawerengedwa kuti zake
kondakitala awiri akunja ndi 15.30mm, kuphatikiza kutchinjiriza ake makulidwe a 3.4mm ndi kondakitala chishango makulidwe 0.5mm, akhoza
kuwoneka kuti m'mimba mwake akunja kokondakita wake ndi 23.1 mm.Yang'anani pa tebulo pamwambapa kuti mudziwe kuti strain clamp yomwe iyenera kukhala
ntchito ndi NLL-5.Ngati ife kusankha zipangizo achepetsa malinga kondakitala m'mimba mwake 15.30mm pa nthawi ino, anasankha
chida choletsa sichingagwiritsidwe ntchito.
Kuonjezera apo, tiyenera kumangitsa zomangira mofanana poika chakufa mapeto achepetsa.Ndikofunikira kuti kupsinjika kwa waya kusakhale
kuonjezera pa kukhudzana pamwamba pakati pa waya ndi zitsulo pambuyo kukhazikitsa, kuteteza waya kuonongeka
ndi chifukwa cha kugwedezeka kwa mphepo kapena kugwedezeka kwina kwa waya.Onetsetsani kuti mphamvu yogwira ya nthiti yakufa pa waya siili
zosakwana 95% za mphamvu yothyola waya.
