NSY/WSY/JSY 6/10KV 1-3 core 25-500mm² sab nraum zoov thiab sab hauv tsev high voltage cross-linked cable tshav kub shrinkable davhlau ya nyob twg thiab intermediate sib koom

Thaum tshav kub kub-shrinkable fais fab cable davhlau ya nyob twg lub taub hau thiab nruab nrab sib koom ua ke series khoom integrate waterproof, kev nyuaj siab tswj thiab rwb thaiv tsev.Nws muaj cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob zoo thiab tuaj yeem siv tau ntev nyob rau hauv ntau yam hnyav ib puag ncig.Nws muaj qhov zoo ntawm lub teeb yuag thiab yooj yim installation.Dav siv nyob rau hauv hluav taws xob fais fab, petrochemical, metallurgy, railway chaw nres nkoj thiab kev tsim kho teb.
Thaum tshav kub kub-shrinkable cable accessories, feem ntau hu ua tshav kub-shrinkable cable hau, yog dav siv nyob rau hauv nruab nrab kev sib txuas thiab terminals ntawm cross-linked cables los yog roj-immersed cables nrog voltage theem qis dua 35KV thiab tshav kub-shrinkable cable accessories.Piv nrog cov tsoos cable accessories, nws muaj cov yam ntxwv ntawm me me, lub teeb yuag, kev nyab xeeb thiab kev ntseeg tau, thiab yooj yim installation.Cov khoom ua tau raws li tus qauv GB11033, kev siv lub sijhawm ntev kub yog -55 ℃ ~ 105 ℃, lub neej kev laus mus txog 20 xyoo, qhov radial shrinkage tus nqi yog ≥50%, qhov ntev shrinkage tus nqi yog tsawg dua 5%. , thiab qhov shrinkage kub yog 110 ℃ ~ 140 ℃ .
Cov ntaub ntawv siv feem ntau yog tsim los ntawm kev sib xyaw ntawm ntau yam khoom siv xws li polyethylene, ethylene-vinyl acetate (EVA) thiab ethylene-propylene roj hmab.
Cov khoom lag luam no tsuas yog siv cov raj kev ntxhov siab los daws qhov teeb meem ntawm hluav taws xob kev ntxhov siab concentration.Ntawd yog, cov txheej txheem tswj kev tswj hwm yog siv los daws qhov kev ntxhov siab ntawm qhov hluav taws xob.
Lub ntsiab zoo yog lub teeb yuag, yooj yim installation thiab kev ua tau zoo.pheej yig tus nqi.
Lub raj muaj kev ntxhov siab yog lub tshav kub shrinkable raj nrog tshwj xeeb hluav taws xob tsis muaj qhov nruab nrab ntim resistivity (1010-1012Ω•cm) thiab siab dielectric tas li (20--25).Cov kev ntsuas hluav taws xob yog siv los yuam kom muaj kev ntxhov siab tawm ntawm qhov tawg ntawm cov kab hluav taws xob rwb thaiv tsev thiab kev tiv thaiv.mus rau hauv ib qho kev faib tawm ntau dua raws li txoj kev ntxhov siab.Cov tshuab no tsuas yog siv tau rau hauv 35kV thiab hauv qab cov khoom siv cable.Vim tias lub raj muaj kev ntxhov siab yuav kub thiab tsis tuaj yeem ua haujlwm thaum qhov hluav taws xob siab siab.
Cov teeb meem tseem ceeb hauv nws txoj kev siv yog: Txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob tsis zoo ntawm lub raj muaj kev ntxhov siab yuav tsum ua kom tau raws li cov txheej txheem teev tseg saum toj no, nws tuaj yeem ua haujlwm.
Ib qho ntxiv, kev saib xyuas yuav tsum tau them rau cov cua sib txawv ntawm cov pob txha ntawm cov txheej txheem ntawm cov cable nrog cov roj silicone nrog txo cov roj thiab txo qee feem tawm.
Cov kab txuas txuas txuas yuav txo qis heev thaum lub sijhawm ua haujlwm vim kev kho tsis zoo hauv kev ntxhov siab.Yog li ntawd, thaum txhim kho cov khoom siv, ua tib zoo saib xyuas qhov sib tshooj ntawm txoj hlua kev ntxhov siab thiab cov ntaub thaiv npog tsis pub tsawg tshaj 20 hli los tiv thaiv cov raj kev ntxhov siab thiab cov ntaub thaiv npog los ntawm kev sib cais thaum lub sij hawm shrinkage.
Vim qhov tsis tshua muaj elasticity ntawm cov cua sov shrinkable accessories, huab cua qhov sib txawv yuav raug tsim ntawm lub interface thaum lub sij hawm thermal expansion thiab contraction thaum lub sij hawm ua hauj lwm, yog li sealing tshuab yog ib qho tseem ceeb los tiv thaiv kev ya raws.
