Product Detail

Khoom cim npe

Nruas clamps yog siv los kho cov conductors thiab xob laim nyob rau hauv cov khoom siv hluav taws xob los yog cov chaw ua haujlwm, thiab txuas lawv mus rau cov hluav taws xob nro los ntawm kev sib txuas cov khoom siv, los yog txuas hluav taws xob rau cov yees.Raws li cov qauv sib txawv thiab cov txheej txheem kev teeb tsa, nws tau muab faib ua plaub pawg: bolt hom, compression hom thiab wedge type, thiab pre-twisted type.
NY nro clamp (hydraulic hom, steel thauj tog rau nkoj vuam) yog tsuas yog siv los kho cov hlau kom dais lub nro ntawm cov hlau, thiab dai cov hlau rau cov khoom siv ntawm cov hlua nro lossis ntauwd.

Technical parameters

Cov khoom nta thiab installation tseem ceeb

Nta:

a.Lub cev clip yog ua los ntawm high-strength aluminium steel khoom.
b.Cov tsos yog du thiab lub neej ua haujlwm ntev.
c.Yooj yim rau nruab thiab siv.
d.Tsis muaj hysteresis poob, thiab nws yog cov khoom uas muaj cov pa roj carbon tsawg, txuag hluav taws xob muaj ntawv pov thawj.

Installation tseem ceeb:

1. Ntxuav ib kawg ntawm cov hlau crimped rau li 1m thiab siv cov roj conductive.
2. Muab lub raj xaim uas huv si (txoj kab uas hla D) mus rau hauv lub xaim kawg thiab rub nws 1m deb ntawm cov hlau kawg.3. Siv lub vernier caliper los yog daim kab xev ntsuas los ntsuas qhov loj l 2 ntawm lub hauv ntej kawg raj ntawm lub steel thauj tog rau nkoj, ntsuas qhov ntev ntawm cov tub ntxhais hlau yuav tsum stripped los ntawm qhov kawg O ntawm cov hlau ON = l 2 + Δl mm (Δl yog 15mm), ua ib lub cim, thiab khi nws ntawm qhov deb ntawm 20mm los ntawm lub cim Coj cov hlua khi tshiab P. 4. Qhib ib ntu ntawm txhuas strand ntawm qhov kawg O, thiab fasten lub exposed steel core kawg nrog ib tug txoj hlua khi.Tom qab ntawd siv lub cutter (los yog txhuas hlau stripper) txiav cov txheej thiab nruab nrab aluminium strands ntawm lub cim N. Thaum txiav lub puab txhuas strands, tsuas yog txiav mus rau 3/4 ntawm txoj kab uas hla ntawm txhua strand, thiab ces tawg lub txhuas strands ib tug. los ntawm ib.Thaum stripping lub txhuas hlau, nws yog nruj me ntsis txwv tsis pub rau bruise lub steel core.)
5. Crimp lub steel thauj tog rau nkoj
A. Xaiv cov yeeb nkab steel tuag "Cd#" uas yog raws li txoj kab uas hla d ntawm cov hlau thauj tog rau nkoj.Cov lus qhia installation rau NY nro clamp nyob rau hauv lub substation yuav tsum xyuas kom meej tias lub diagonal lub kaum sab xis ntawm lub hexagonal tuag yog dmm;
B. Nias cov hlau Tom qab cov tub ntxhais tau ntxuav, tig thiab ntxig rau hauv qab ntawm cov hlau thauj tog rau nkoj raws txoj kev stranding ntawm cov tub ntxhais hlau, thiab cov
kawg ntawm cov hlau thauj tog rau nkoj nthuav tawm cov tub ntxhais hlau nrog qhov ntev li ntawm 15mm;Lub sijhawm no, cov xov hlau ntawm ob sab yuav tsum yog
khaws cov kab rov tav nrog cov hlau thauj tog rau nkoj, thiab ua raws li cov axis ntawm hydraulic xovxwm, thiaj li yuav txo tau qhov tuaj yeem khoov ntawm cov yeeb nkab tom qab compressed.
D. Crimp rau pem hauv ntej kawg yeeb nkab ntawm steel thauj tog rau nkoj.Cov kev taw qhia ntawm crimping yog los ntawm qhov zawj ntawm cov yeeb nkab mus rau lub qhov ncauj yeeb nkab.Thaum thov kev siab, ob lub pwm uas nyob ib sab
yuav tsum sib tshooj tsawg kawg 5-10mm.Tom qab compression rau hauv ib lub hexagon tsis tu ncua, qhov kev ncua deb S ntawm cov sab nraud ntawm lub hexagon li niaj zaus yuav tsum raug txheeb xyuas.Tus nqi tso cai ntawm S yog: S = (0.866 * 0.993d) + 0.2.Tom qab molding, siv tus qauv caliper los xyuas qhov luaj li cas ntawm qhov opposite sab nrug tom qab nias.(Ceeb Toom: Lub siab tiag tiag ntawm lub twj tso kua mis hydraulic yuav tsum tsis txhob qis dua 80Mp, thiab thaum lub siab ncav cuag tus nqi, nws yuav tsum tau khaws cia rau 3-5s).Txuas ntxiv hydraulic ua haujlwm tsuas yog tom qab tus qauv tau ua tiav.
