Ukukhethwa kwe-i-dead end clampinqunywa ngokuyinhloko ngokwezimo ezihlukene zamakhondatha wezintambo zikagesi.

Kunezimo ezimbili ezivamile.Umkhiqizi wokufakwa kwamandla uzokuchazela.

1. Ukukhethwa kwezinsimbi zokucindezela ulayini lapho kusetshenziswa izikhondatha ze-LGJ ne-LJ

Uma usebenzisa i-LGJ noma i-LJ wire, kusukelai-dead end clampiboshelwe kububanzi obungaphandle bocingo lapho isetshenziswa, imodeli ye

i-dead end clamp esetshenzisiwe kufanele ikhethwe ngokuya ngobubanzi obungaphandle bocingo.Isibonelo, intambo ye-LGJ-185/30 isetshenziswa

kulayini wamandla.Ngemva kokubala, kungatholakala ukuthi ububanzi bayo obungaphandle bungu-18.88mm.Kusukela etafuleni elingenhla, kuyaziwa ukuthi

i-dead end clamp kufanele ibe yi-NLL-4, NLL-5 noma i-NLD-4.

Kufanele kuqashelwe lapha ukuthi ububanzi bangaphandle LGJ wire ibalwa kusukela cross-section of aluminium wire 185mm.

kanye nengxenye yesiphambano sensimbi engu-30mm.Ayibalwa nje nge-cross-section ye-aluminium wire 185mm.Izintambo ze-LGJ

Ukucaciswa okufanayo kunezingxenye ezihlukene zensimbi eziyisiphambano kanye namadayamitha angaphandle ocingo, ngakho-ke isigxivizo sokuphela se-thedead esisetshenziselwa i-LGJ

izintambo zokucaciswa okufanayo azifani ngempela.Uma kuwucingo lwe-LJ, njengoba ingenawo umgogodla wensimbi, ingxenye ephambanayo

yocingo oluyi-aluminium oluyintambo lungasetshenziswa ukubala ububanzi bangaphandle bocingo.

Ngaphezu kwalokho, njengoba i-dead end clamp iboshiwe kububanzi obungaphandle bocingo, sidinga ukuthi ungqimba lwangaphandle lwe-LGJ

noma intambo ye-LJ imbozwe ngeteyiphu ye-aluminium ngesikhathi sokwakhiwa ukuze kuvinjwe umonakalo ocingweni ngesikhathi sokuqothuka.

2. Ukukhethwa kocingo olucisha umugqa lapho kusetshenziswa ucingo oluvalekile

Ezindaweni eziminyene, ezinezinkuni, nezingcolile, siya ngokuya sisebenzisa izintambo ezivalekile esikhundleni sezintambo ezingenalutho.Uma kuqhathaniswa

ngezintambo ezingenalutho, inezinzuzo zokuphepha okuphezulu nokuthembeka, ukulahleka kwezintambo eziphansi, nokugqwala okuncane kwezintambo.Lapho usebenzisa i-insulated

izintambo, sidinga ukunaka iqiniso lokuthi i-dead end clamp iboshwe ku-diameter yangaphandle "yecingo" esikhundleni

I-diameter yangaphandle "ye-conductor" lapho isetshenziswa, ngakho-ke kufanele isekelwe kububanzi obungaphandle bocingo esikhundleni se-diameter yangaphandle.

"komqhubi".I-diameter yangaphandle ye-conductor isetshenziselwa ukukhetha uhlobo lwe-dead end clamp esetshenzisiwe.Isibonelo, i-JKLGYJ

-150/8 intambo yasemoyeni eqinisiwe ye-polyethylene insulated yasemoyeni isetshenziswa emugqeni wamandla.Kubalwa ukuthi yayo

I-conductor diameter yangaphandle ingu-15.30mm, kanye nogqinsi lwalo lwe-insulation oluyi-3.4mm kanye nogqinsi lokuvikela isivikelo esingu-0.5mm, lungakwazi

kubonakala ukuthi ububanzi obungaphandle bomqhubi wayo buyi-23.1 mm.Hlola ithebula elingenhla ukuze wazi ukuthi i-strain clamp okufanele ibe yiyo

esetshenziswa yi-NLL-5.Uma sikhetha i-clamp yemishini ngokusho kwe-conductor yangaphandle ububanzi obuyi-15.30mm ngalesi sikhathi, okukhethiwe

I-clamp yemishini ayikwazi ukusetshenziswa.

Ngaphezu kwalokho, kufanele siqinise izikulufu ngokulinganayo lapho sifaka i-dead end clamp.Kudingeka ukuthi ukucindezeleka kocingo akukwenzi

ukwanda endaweni yokuxhumana phakathi kocingo nensimbi ngemva kokufakwa, ukuze kuvinjwe ucingo ukuthi lungalimali

futhi kubangelwa ukudlidliza komoya noma okunye ukudlidliza kocingo.Qinisekisa ukuthi amandla okubamba we-dead end clamp ocingweni awekho

ngaphansi kwama-95% wamandla okuphuka kwentambo.
