Qhov Sib Txawv Ntawm Cov Cables Uas Tiv Thaiv Kub Qis Thiab Cov Cables Txheem

Cov xov hlau uas tiv taus qhov kub tsawg (feem ntau hu ua "cov xov hlau uas tiv taus txias") yog ib hom xov hlau tshwj xeeb uas tsim los rau qhov chaw kub tsawg heev. Lawv lub hauv paus yog siv cov khoom siv tiv taus qhov kub tsawg tshwj xeeb, ua rau lawv tswj tau cov khoom siv hluav taws xob thiab tshuab zoo heev txawm tias nyob rau hauv qhov xwm txheej hnyav li -40 ° C txog -60 ° C. Qhov sib txawv, cov xov hlau txheem muaj kev poob qis sai hauv cov chaw zoo li no thiab tsis tuaj yeem lav qhov kev ua haujlwm zoo thiab txhim khu kev qha.

1. Qhov Txawv Tseem Ceeb: Kev Xaiv Khoom Siv

Cov khoom siv yog qhov tseem ceeb uas txiav txim siab qhov tsis kam ntawm qhov kub thiab txias ntawm lub cable, feem ntau pom nyob rau hauv kev rwb thaiv tsev thiab lub plhaub.

Cov Khoom Siv Rwb Thaiv Tsev

Cov Cables Tiv Thaiv Kub Qis: Siv cov khoom siv rwb thaiv tsev tshwj xeeb xws li fluoropolymers, Polyurethane (PU), low-temperature modified PVC, thiab low-temperature Cross-Linked Polyethylene (XLPE). Cov ntaub ntawv no muaj cov qauv molecular nrog kev ywj pheej qis hauv qhov kub qis, ua kom ntseeg tau tias cov txheej rwb thaiv tsev tsis tawg lossis ntsws thaum txias heev.

Cov Cables Txheem: Feem ntau siv cov PVC txheem lossisXLPE, uas sai sai hardens thiab embrittles ntawm qhov kub qis, ua rau tsis ua haujlwm rwb thaiv tsev.

Cov Khoom Siv Sheathing

Cov Cables Tiv Thaiv Kub Qis: Lub plhaub sab nraud feem ntau siv Nitrile Rubber, Chloroprene Rubber (CR), EPDM, Thermoplastic Polyurethane (TPU), lossis cov khoom siv tshwj xeeb uas tsis kub heevCov ntaub ntawv LSZHCov ntaub ntawv no tsis yog tsuas yog tiv taus qhov kub tsawg xwb tab sis kuj muaj kev tiv thaiv zoo heev, tiv taus roj, tiv taus UV, thiab tiv taus huab cua, muab kev tiv thaiv dav dav rau lub cable.

Cov Cables Txheem: Lub sheath feem ntau yog ua los ntawm cov qauv PVC lossis Polyethylene (PE), uas yooj yim laus thiab tawg nyob rau hauv kev ntxhov siab ua ke ntawm qhov kub thiab txias thiab ib puag ncig nyuaj, poob nws txoj haujlwm tiv thaiv.

2. Qhov sib txawv ntawm cov qauv thiab kev ua tau zoo

Raws li cov khoom siv, ob hom cables qhia txog qhov sib txawv tseem ceeb hauv kev tsim qauv thiab kev ua tau zoo kawg.

Tus Neeg Txuas Lus thiab Kev Tsim Qauv

Cov Cables Uas Tiv Thaiv Tau Kub Qis:

Tus Neeg Txuas Lus: Feem ntau siv ntau txoj hlua, zoo heev, cov xov hlau tooj liab lossis cov xov hlau tooj liab uas tsis muaj oxygen, ua rau lub cable yooj ywm thiab tiv taus oxidation zoo dua.

Cov Qauv: Qhov ntev ntawm lub hauv paus zoo tshaj plaws thiab muaj peev xwm ntxiv cov fibers tensile, cov txheej tiv thaiv kev sib ntswg, lossis cov txheej buffer los txhim kho kev khoov, kev sib ntswg, thiab kev cuam tshuam, tsim nyog rau kev siv txav mus los.

Cov Cables Txheem: Cov qauv no yog tsim los rau kev teeb tsa zoo li qub hauv qhov kub thiab txias, nrog rau kev ywj pheej ntawm cov xov hlau qis dua thiab kev txhawb nqa tsawg dua.

Kev Sib Piv Txog Kev Ua Tau Zoo Tseem Ceeb

Cov Cables Uas Tiv Thaiv Tau Kub Qis:

Kev Ua Haujlwm Mechanical: Tswj tau qhov yooj ywm siab, lub zog tensile siab, thiab kev tiv taus kev qaug zog txawm tias nyob rau hauv qhov txias heev.

Kev Ua Haujlwm Hluav Taws Xob: Muaj peev xwm tswj tau qhov ruaj khov ntawm kev rwb thaiv tsev thiab qhov voltage withstand theem, nrog rau kev ua tau zoo heev.

Kev Tiv Thaiv Ib Puag Ncig: Muaj kev tiv thaiv kev sib txhuam zoo heev, kev tiv thaiv kev xeb ntawm cov tshuaj lom neeg, thiab kev tiv thaiv huab cua.

Cov Cables Txheem:

Kev Ua Haujlwm Mechanical: Poob qhov yooj ywm thaum kub qis; lub plhaub thiab cov rwb thaiv tsev yooj yim tawg, ua rau lawv yooj yim raug puas tsuaj los ntawm kev siv tshuab.

Kev Ua Haujlwm Hluav Taws Xob: Kev tiv thaiv rwb thaiv tsev txo qis heev, qhov kev pheej hmoo ntawm kev tawg nce ntxiv, ua rau muaj kev phom sij loj heev.

3. Cov Xwm Txheej Thov thiab Kev Xav Txog Kev Lag Luam

Qhov sib txawv ntawm kev ua tau zoo ncaj qha txiav txim siab lawv cov teb thov thiab kev lag luam muaj txiaj ntsig.

Cov Xwm Txheej ntawm Daim Ntawv Thov

Cov Cables Tiv Thaiv Kub Qis: Puas yog qhov kev xaiv tsim nyog rau thaj chaw xws li thaj chaw polar, chaw cia khoom txias hauv kev lag luam, thaj chaw siab, lub nkoj, lub zog cua sab nraum zoov, cov khoom siv hauv dej hiav txwv tob, metallurgy, petrochemicals, aerospace, thiab kev tshawb fawb Antarctic.

Cov Cables Txheem: Tsuas yog tsim nyog rau kev faib hluav taws xob sab hauv tsev, thiab cov tsev lag luam thiab pej xeem ib txwm muaj nyob rau hauv thaj chaw huab cua sov thiab lwm qhov chaw kub.

Kev Teeb tsa thiab Kev Txij Nkawm

Cov Cables Tiv Thaiv Kub Qis: Tsim los rau kev teeb tsa kub qis; qee zaum, tuaj yeem siv nrog kev ntsuas ua ntej cua sov, muab kev yooj yim rau kev teeb tsa, kev ntseeg siab ntawm lub kaw lus, thiab kev saib xyuas tsawg zaus.

Cov Cables Txheem: Kev teeb tsa rau hauv qhov chaw kub qis yog txwv tsis pub ua, vim nws tuaj yeem ua rau puas tsuaj mus tas li rau cov txheej rwb thaiv tsev, ua rau cov nqi kho tom qab ntawd siab.

Kev Tshuaj Xyuas Tus Nqi

Cov Cables Uas Tiv Thaiv Tau Kub Qis: Vim yog siv cov khoom siv tshwj xeeb thiab cov txheej txheem nyuaj, tus nqi yuav khoom thawj zaug siab dua. Txawm li cas los xij, hauv lawv qhov chaw tsim, lawv muab kev ua tau zoo thiab lub neej ua haujlwm ntev, ua rau tus nqi tag nrho ntawm kev muaj qis dua.

Cov Cables Txheem: Muaj tus nqi pib qis, tab sis yog tias siv tsis raug hauv qhov chaw kub qis, lawv yuav ua rau muaj kev ua tsis tiav ntau zaus, lub sijhawm tsis ua haujlwm, thiab xwm txheej kev nyab xeeb, ua rau tus nqi tag nrho siab dua.

Kev Txheeb Xyuas

Kev xaiv ntawm cov cables uas tiv taus qhov kub qis thiab cov cables txheem tsis yog qhov kev txiav txim siab yooj yim raws li tus nqi xwb, tab sis yog kev txiav txim siab txog kev tsim kho tshuab uas txiav txim siab los ntawm qhov kub thiab txias ntawm qhov chaw siv. Kev xaiv kom raug yog qhov yuav tsum tau ua ua ntej kom ntseeg tau tias muaj kev nyab xeeb, ruaj khov, thiab ua haujlwm ntev ntawm cov tshuab fais fab hauv qhov chaw kub qis.
