Hauv kev tsim cov xov hlau, kev xaiv cov ntaub ntawv rwb thaiv tsev cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov khoom, lub neej ua haujlwm, thiab kev nyab xeeb hauv kev ua haujlwm. Cov ntaub ntawv rwb thaiv tsev feem ntau siv niaj hnub no suav nrog Polyvinyl Chloride (PVC), Polyethylene (PE), thiab Cross-linked Polyethylene (XLPE). Vim lawv cov qauv molecular sib txawv thiab cov khoom siv, txhua tus haum rau ntau qhov xwm txheej siv.
1. Polyvinyl Chloride (PVC) Kev Rwb Thaiv Tsev
PVC yog ib qho ntawm cov ntaub ntawv rwb thaiv tsev cable uas siv dav tshaj plaws, paub txog nws lub zog zoo, yooj yim ua, thiab tiv taus cov kua qaub thiab alkalis zoo heev. Los ntawm kev ntxiv cov khoom ntxiv uas tiv taus hluav taws rau hauv nws cov qauv, PVC rwb thaiv tsev tuaj yeem ua tiav kev ua haujlwm tiv taus hluav taws zoo, ua rau nws tsim nyog rau cov xov hlau thiab cables dav dav.
Nyob ntawm seb qhov tawv npaum li cas, cov PVC uas yoog tau feem ntau yog siv rau cov txheej rwb thaiv tsev, thaum cov PVC tawv feem ntau yog siv ua cov ntaub thaiv cable. Nws yuav tsum nco ntsoov tias qhov kub thiab txias uas tso cai rau kev ua haujlwm ntev (qhov kub ntawm tus neeg coj hluav taws xob) ntawm cov cables PVC-insulated feem ntau yog 70 ° C, thiab PVC tuaj yeem tsim cov pa luam yeeb ntom ntom thaum raug hluav taws.
2. Kev rwb thaiv tsev Polyethylene (PE)
PE rwb thaiv tsev yog tus cwj pwm los ntawm nws cov khoom hluav taws xob zoo tshaj plaws, suav nrog dielectric tsis tu ncua qis, dielectric poob qis, thiab ntim resistivity siab, ua rau nws tsim nyog rau kev xa cov teeb liab zaus siab. Tsis tas li ntawd, PE ua rau muaj kev ua tau zoo heev hauv qhov kub qis thiab kev ruaj khov tshuaj lom neeg.
Cov xov hlau PE-insulated siv dav hauv cov xov hlau sib txuas lus, cov xov hlau coaxial, thiab cov xov hlau fais fab qis-rau-nruab nrab. Qhov kub ua haujlwm ntev (kub ntawm tus neeg coj) ntawm PE rwb thaiv tsev feem ntau yog 70 ° C.
3.Polyethylene txuas nrog (XLPE)Kev rwb thaiv tsev
XLPE yog ib yam khoom siv thermosetting uas tsim los ntawm kev sib txuas ntawm cov qauv molecular ntawm PE mus rau hauv ib lub network peb-seem. Cov txheej txheem sib txuas no ua rau muaj kev txhim kho zoo hauv kev ua haujlwm ntawm cov khoom.
XLPE rwb thaiv tsev muaj cov hauv qab no:
Qhov kub ua haujlwm ntev uas tso cai tau nce mus txog 90 ° C
Kev tiv thaiv kub luv luv txog li 250 ° C
Txhim kho lub zog kho tshuab thiab txhim kho kev tiv thaiv rau kev tawg ntawm kev ntxhov siab ib puag ncig
Tib lub sijhawm, XLPE khaws cov khoom siv hluav taws xob zoo heev ntawm PE. Yog li ntawd, XLPE tau dhau los ua cov khoom siv rwb thaiv tsev zoo tshaj plaws rau cov xov hluav taws xob nruab nrab thiab siab, cov xov hluav taws xob tshiab, thiab cov ntawv thov kev lag luam nrog cov xwm txheej ua haujlwm nyuaj.
4. Phau Ntawv Qhia Xaiv Daim Ntawv Thov
PVC-cov xov hlau rwb thaiv tsev: Kev lag luam thiab siv tau, tsim nyog rau cov xov hlau hauv tsev, cov xov hlau tswj dav dav, thiab lwm qhov chaw qhuav.
Cov xov hlau PE-insulated: Kev ua haujlwm hluav taws xob zoo heev, zoo tagnrho rau kev sib txuas lus cov ntaub ntawv, kev xa cov teeb liab, thiab cov ntawv thov uas xav tau cov yam ntxwv ruaj khov.
Cov xov hlau XLPE-insulated: Kev ua haujlwm siab, pom zoo rau cov tes hauj lwm xa hluav taws xob, qhov chaw kub siab, huab cua noo, thiab kev siv hauv kev lag luam nrog kev ntseeg siab heev.
Hauv kev siv engineering, kev xaiv cov khoom siv rwb thaiv tsev yuav tsum xav txog qhov kub thiab txias ua haujlwm, tej yam kev mob ib puag ncig, cov yam ntxwv hluav taws xob, cov kev xav tau kho tshuab, thiab cov peev nyiaj siv. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev tsim khoom loj, qhov sib piv ntawm tus nqi thiab kev ua tau zoo ntawm XLPE cables txuas ntxiv txhim kho, ua rau lawv cov kev siv dav dua.
Txog Peb
Ua ib lub tuam txhab muab cov khoom siv cable tshaj lij, ONE WORLD tau tsim cov kab ntau lawm rau PE, XLPE, thiab PVC rwb thaiv tsev, txhawb nqa los ntawm cov khoom siv kuaj siab heev xws li Melt Flow Rate Testers, Hot Set / Heat Elongation Testers, thiab High-Voltage Breakdown Test Systems, muab lub hauv paus kho vajtse ruaj khov rau kev lees paub zoo ntawm cov khoom.
