Ua haujlwm kub: 90 ℃, 125 ℃, thiab lwm yam.
Kev ntsuas hluav taws xob: U0 / U: 0.6 / 1KV
Yam tsawg kawg nkaus dabtsi yog khoov vojvoog: tsis pub tsawg tshaj 6 npaug ntawm sab nraud txoj kab uas hla
Lub neej kev pab cuam ntawm cable tsis tsawg tshaj 25 xyoo.
4. Performance indicators, As
DC tsis kam ntawm tus neeg xyuas pib ntawm 20 ° C ua tau raws li IEC60228 tus qauv (GB3956).
Lub rwb thaiv tsev ntawm cov kab hluav taws xob ntawm 20 ° C tsis tsawg dua 5000MΩ·km (ntau dua li qhov ua tau zoo ntawm cov rwb thaiv tsev tsis tu ncua uas xav tau los ntawm IEC60092-353 tus qauv).
Cov nplaim hluav taws kub hnyiab tau ua tau raws li qhov yuav tsum tau ua ntawm IEC60332-3-22 Class A nplaim retardant (hluav taws rau 40 feeb, thiab qhov siab carbonization ntawm cable tsis pub tshaj 2.5m).
Rau cov hluav taws kub-resistant cables, lawv cov hluav taws-resistant kev ua tau zoo raws li IEC60331 (90 feeb (tshuaj tua hluav taws) + 15 feeb (tom qab tua hluav taws), nplaim taws kub 750 ℃ (0 ~ + 50 ℃) cable fais fab mov yog ib txwm, tsis muaj hluav taws xob).
Qhov ntsuas hluav taws xob tsis muaj halogen tsis muaj hluav taws xob tsawg ua tau raws li qhov yuav tsum tau ua ntawm IEC60754.2, halogen acid tso pa tawm tsis ntau tshaj 5mg / g, qhov tshwj xeeb tshawb pom ntawm nws tus nqi pH tsis tsawg dua 4.3, thiab cov conductivity tsis yog. ntau tshaj 10μs / mm.
Kev ua tau zoo ntawm cov pa luam yeeb tsawg: Cov pa luam yeeb ntom ntom (lub teeb xa hluav taws xob) ntawm lub cable tsis tsawg dua 60%.Ua tau raws li tus qauv kev cai ntawm IEC61034.
5. Cable qauv
Tus neeg xyuas pib yog ua los ntawm cov khoom zoo annealed tinned tooj liab.Hom neeg xyuas pib no muaj kev tiv thaiv corrosion zoo heev.Cov qauv ntawm tus neeg xyuas pib muab faib ua cov khoom siv hluav taws xob, cov khoom sib txuas thiab cov khoom muag muag.
Lub rwb thaiv tsev adopts extruded rwb thaiv tsev.Txoj kev extrusion no tuaj yeem txo cov roj ntawm tus neeg xyuas pib thiab cov rwb thaiv tsev kom tiv thaiv kev nkag ntawm impurities xws li dej vapor.
Cov xim code feem ntau txawv ntawm cov xim.Cov xim tuaj yeem xaiv thiab ua tiav raws li qhov chaw xav tau rau kev teeb tsa yooj yim.
Sab hauv sheath / liner (Jacket) yog cov khoom siv tsis muaj pa taws tsis muaj halogen nrog cov nplaim hluav taws kub.Cov khoom yog halogen dawb.
Armor txheej (Armor) yog ib hom braided.Hom armor no muaj kev yooj yim dua thiab yooj yim rau kev tso cable.Braided armor cov ntaub ntawv suav nrog tinned tooj liab hlau thiab galvanized steel hlau, ob qho tib si uas muaj kev tiv thaiv corrosion zoo.
Cov khoom siv sab nrauv (Sheath) kuj yog cov khoom siv tsis muaj pa halogen tsawg.Qhov no ua rau tsis muaj kuab lom thaum hlawv thiab tsim cov pa taws me me.Nws yog siv ntau dua nyob rau hauv cov chaw muaj neeg coob coob.
Kev txheeb xyuas ntawm lub cable tuaj yeem luam tawm raws li qhov xav tau tiag tiag.
