Ukhetho lwei-dead end clampigqitywe ngokukodwa ngokweemeko ezahlukeneyo zabaqhubi beentambo zamandla.

Kukho iimeko ezimbini eziqhelekileyo.Umenzi wezixhobo zombane uya kukuchazela.

1. Ukukhethwa kwee-clamps ze-line strain xa kusetyenziswa ii-LGJ kunye ne-LJ conductors

Xa usebenzisa LGJ okanye LJ ucingo, ukususelai-dead end clampibambekile kwi-diameter yangaphandle yocingo xa isetyenziswa, imodeli ye

i-dead end clamp esetyenzisiweyo kufuneka ikhethwe ngokwe-diameter yangaphandle yocingo.Ngokomzekelo, ucingo lwe-LGJ-185/30 lusetyenziswa

kumgca wamandla.Emva kokubala, kunokufunyanwa ukuba i-diameter yayo yangaphandle yi-18.88mm.Ukusuka kule theyibhile ingentla, iyaziwa loo nto

i-dead end clamp kufuneka ibe yi-NLL-4, NLL-5 okanye i-NLD-4.

Kufuneka kuqatshelwe apha ukuba i-diameter yangaphandle ye-LGJ wire ibalwa ukusuka kwi-cross-section ye-aluminium wire 185mm.

kunye ne-cross-section of steel core 30mm.Akunjalo nje kubalwa nge-cross-section of aluminium wire 185mm.Iingcingo ze-LGJ

Ubalulo olufanayo lunamacandelo ahlukeneyo entsimbi engundoqo kunye needamitha zangaphandle zocingo, ngoko ke i-clamp efileyo esetyenziselwa i-LGJ

iingcingo ezineenkcukacha ezifanayo azifani.Ukuba lucingo lwe-LJ, ekubeni ingenayo i-core yentsimbi, i-cross-section

yocingo lwe-aluminiyam oluphothiweyo lunokusetyenziswa ukubala i-diameter yangaphandle yocingo.

Ukongeza, ekubeni i-clamp efileyo ibambekile kwi-diameter yangaphandle yocingo, sifuna ukuba umaleko wangaphandle we-LGJ.

okanye ucingo lwe-LJ lugqunywe nge-aluminiyam tape ngexesha lokwakha ukukhusela umonakalo kwi-wire ngexesha le-crimping.

2. Ukukhethwa kocingo oluvale isiphelo xa kusetyenziswa ucingo olugqunyiweyo

Kwimimandla enabemi abaninzi, enemithi, nengcolisekileyo, siya sisebenzisa iingcingo ezigqunyiweyo endaweni yocingo olungenanto.Xa kuthelekiswa

ngeengcingo ezingenanto, ineengenelo zokhuseleko oluphezulu kunye nokuthembeka, ilahleko esezantsi yocingo, kunye ne-corrosion encinci yocingo.Xa usebenzisa i-insulated

iingcingo, kufuneka sinikele ingqalelo kwinto yokuba i-dead end clamp ibotshelelwe kwi-diameter yangaphandle ye "wire" endaweni yocingo.

Idayimitha engaphandle ye "conductor" xa isetyenziswa, ngoko ke kufuneka isekelwe kwi-diameter yangaphandle yocingo endaweni yobubanzi obungaphandle.

"komqhubi".I-diameter yangaphandle ye-conductor isetyenziselwa ukukhetha uhlobo lwe-dead end clamp esetyenzisiweyo.Umzekelo, JKLGYJ

-150/8 intsimbi engundoqo eyomeleziweyo i-polyethylene insulated intambo yomoya isetyenziswa kumgca wamandla.Kubalwa ukuba yayo

Idayamitha ye-conductor yangaphandle yi-15.30mm, kunye nobukhulu bayo bokufakelwa kwe-3.4mm kunye nobukhulu bokukhusela i-conductor yi-0.5mm, ingaba

kubonakala ukuba i-diameter yangaphandle yomqhubi wayo yi-23.1 mm.Jonga le theyibhile ingentla ukwazi ukuba i-strain clamp ekufuneka ibe yiyo

esetyenzisiweyo yi-NLL-5.Ukuba sikhetha i-clamp yesixhobo ngokwe-conductor yangaphandle ye-15.30mm ngeli xesha, ekhethiweyo

isixhobo esibambekayo asinakusetyenziswa.

Ukongeza, kufuneka siqinise izikhonkwane ngokulinganayo xa ufaka i-clamp efile.Kuyimfuneko ukuba uxinzelelo lwentambo alufuni

ukwanda kwindawo yokudibanisa phakathi kocingo kunye nentsimbi emva kokufakwa, ukwenzela ukuba uthintele ukuba ucingo lungonakali

kunye nebangelwa kukungcangcazela kwempepho okanye okunye ukungcangcazela kocingo.Qinisekisa ukuba amandla okubamba i-dead end clamp kucingo alukho

ngaphantsi kwe-95% yamandla okuqhawula ucingo.
