Hais txog kev pub mus ntev ntev rau kev siv cable, pev roj hmab feem ntau yog nyob ntawm 65 ° C, thiab tus ntoo khaublig-° (XLPE) rwb thaiv tsev ntawm 90 ° C. Rau luv luv-ciration (nrog rau lub sijhawm siab tshaj plaws tsis tau tshaj li 5 vib nas this), tus neeg xyuas kev coj ua tau zoo tshaj plaws yog 160 ° C rau XLPE rwb thaiv tsev.
I. Qhov txawv ntawm XLPE cable thiab PVC CABLE
1. Cov lus qhia ntxiv, tau pom zoo li cas rau ib nrab xyoo Piv rau pvc cables, XLPE Cab xwm txheej ntxiv tam sim no-muaj peev xwm, muaj zog tshaj li ntawm lub zog (pvc xyoo nyob rau hauv dej siab, thaum XLPE cable lifespan yog feem ntau 40 xyoo). Thaum hlawv, pvc tso tawm cov pa luam yeeb dub dub thiab toxic roj, hos xlpe combustion tsis tsim cov roj toxent. Cov hluav taws xob zoo tshaj ntawm cov xas sib txuas yog nce tau los ntawm kev tsim qauv thiab kev thov cov haujlwm.
2. Cleshi pvc cables (rwb thaiv tsev thiab sheath) hlawv sai sai nrog hluav taws xob nrawm nrawm nrawm nrawm. Lawv poob lub zog hluav taws xob muaj peev xwm tsis pub dhau 1 mus rau 2 feeb. PVC combusion tso cov pa luam yeeb dub tuab, ua rau ua pa nyuaj thiab kev khiav tawm kev nyuaj. Ntau tus thuam, PVC combusion tso tawm cov roj ntsha thiab cov roj corrosive xws li hydrogen chloride (HCl) thiab cov ris tsho loj, cov nyiaj txiag rau 80% ntawm hluav taws-cuam tshuam txog kev tuag). Cov roj av cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob, kev hloov pauv hluav taws xob ntau ntxiv rau kev ua haujlwm thiab ua rau txo qis.
Ii. Nplaim taws-retardant cables
1. Cov nplaim taws-retardant Chav kawm ib qho muaj cov nplaim taws siab tshaj plaws-retardant.
Kev sib tw sib xyaw ua ke ntawm nplaim taws-retardant thiab tsis-nplaim-retardant cov xov hlau tau ua los ntawm US cov qauv kev tshawb fawb thiab kev tshawb fawb thev naus laus zis. Cov txiaj ntsig hauv qab no tau hais txog qhov tseem ceeb ntawm kev siv nplaim taws-retardant cables:
a. Cov xov hluav taws xob-retardant cov xov hlau muab tshaj 15 zaug ntxiv lub sijhawm khiav piv rau cov xov hlau tsis yog-retardant.
b. Nplaim taws-retardant xov hlau hlawv tsuas yog ib nrab ntawm cov khoom siv uas tsis yog-nplaim-retardant.
c. Cov xov xwm nplaim hluav taws xob ua kom pom cov xov hluav taws xob ib qho kev tso tawm ib lub hlis twg ntawm qhov uas tsis yog-cov xov hluav taws xob.
d. Cov roj muaj roj lom tawm los ntawm kev sib txuas yog tsuas yog ib feem peb ntawm cov khoom uas tsis yog nplaim-retardant.
e. Cov khoom lag luam luam yeeb tsis muaj qhov sib txawv ntawm nplaim taws thiab cov khoom siv uas tsis yog nplaim taws.
2. Halogen-dawb cov pa hluav taws
Halogen-Pub cov pa hluav taws uas tsis muaj pa hluav taws xob tsawg yuav tsum tau muaj Halogen-dawb, cov pa hluav taws, thiab nplaim hluav taws xob zoo, nrog cov lus qhia tshwj xeeb hauv qab no:
IEC 60754 (Halogen-Free Test) IEC 61034 (Kev Ntsuam Xyuas Nyiaj Tsawg)
Ph ntawv tsav loj conductivity tsawg kawg ntawm kev hloov pauv
PH≥4.3 b≤10US / hli T≥60%
3. Hluav taws kub-resistant cables
a. Hluav Taws Kub-Resistant Cable Combusation Kev Ntsuas Qhov Ntsuas (hluav taws kub thiab sijhawm) raws li IEC 331-1970 tus qauv yog 750 ° C rau 3 teev. Raws li IEC 60331 tshiab tshiab tshiab los ntawm IC pov npav tam sim no, qhov hluav taws kub kub los ntawm 750 ° C rau 800 ° C rau 3 teev.
b. Hluav taws kub hluav taws xob thiab cov cab kuj tuaj yeem faib rau nplaim taws-retardant hluav taws xob-resistant cables-resistant cables Cov Hluav Taws Xob Hluav Taws Xob-Prosiverant Cov uas tau ntsib cov qauv hauv chav kawm feem ntau ua haujlwm hluav taws xob tshwj xeeb (tooj liab, tooj liab
Cov ntxhia pob zeb-insulated hluav taws-resistant cables yog tsis muaj pa taws, yog corrosion-resistant, kev cuam tshuam-resistant, kev cuam tshuam-resistant, thiab tiv thaiv tshuaj tsuag tshuaj. Lawv tau paub tias yog cov hluav taws kub hnyiab, cov hluav taws xob ua tau zoo tshaj plaws ntawm cov hluav taws-resistant cable ntau yam. Txawm li cas los xij, lawv cov txheej txheem tsim khoom yog cov nyom, lawv tus nqi ntau dua, lawv cov rwb thaiv tsev yog tsawg, thiab tam sim no, tsuas yog ib qho khoom lag luam ntawm 25mm thiab saum toj no tuaj yeem muab. Yuav muaj kev kawm tas mus li ntawm cov chaw thiab cov kev sib txuas hauv nruab nrab yog qhov tsim nyog, ua kev teeb tsa thiab tsim kho ntau yam nyuaj.
