Nws cov qauv sib xyaw ua ke tshwj xeeb qhia txog kev txiav txim siab dav dav txog kev ua haujlwm hluav taws xob, kev tiv thaiv tshuab, thiab kev hloov pauv ib puag ncig, thiab nws siv dav hauv ntau yam kev lag luam, kev tsim kho, thiab cov chaw tshwj xeeb.
II. Cov Qauv Tsim
(I) Polyethylene (PE) Sab Hauv Rwb Thaiv Tsev (IS)
Kev Pov Hwm Tseem Ceeb rau Kev Rwb Thaiv Hluav Taws Xob
Ua ib txoj kab tiv thaiv thawj zaug rau kev rwb thaiv tsev sab hauv lub cable, PE txheej rwb thaiv tsev sab hauv muaj kev ua haujlwm rwb thaiv tsev zoo heev. Nws tuaj yeem thaiv kev coj hluav taws xob tsis zoo ntawm cov xov hlau, ua kom lub zog hluav taws xob raug xa mus raws txoj kev uas tau teem tseg. Nws cov yam ntxwv tiv thaiv rwb thaiv tsev siab ua rau lub cable tswj tau lub xeev rwb thaiv tsev zoo thaum raug rau qhov ntsuas hluav taws xob lossis txawm tias qee qib ntawm kev dhau hluav taws xob, tiv thaiv cov xwm txheej txaus ntshai xws li hluav taws xob luv luv.
Kev Txhawb Nqa Rau Kev Ruaj Ntseg ntawm Cov Qauv
Cov txheej PE rwb thaiv tsev sab hauv yog cov qauv sib xws thiab muaj qee qhov elasticity, muab kev txhawb nqa ruaj khov rau cov qauv sab hauv ntawm lub cable. Thaum lub cable raug rau cov zog sab nraud xws li khoov, ncab, lossis me ntsis compression, nws tuaj yeem tswj nws cov duab thiab kev ua haujlwm rwb thaiv tsev hluav taws xob, yog li ua kom ntseeg tau tias qhov kev ncaj ncees ntawm tag nrho cov qauv cable thiab kev ruaj khov ntawm kev ua haujlwm hluav taws xob.
(II) Polyethylene (PE) Txheej rwb thaiv tsev sab nraud (OS)
Kev Ua Haujlwm Rwb Thaiv Hluav Taws Xob Zoo Dua
Cov txheej PE rwb thaiv tsev sab nraud uas nyob sab nraud ntawm cov txheej rwb thaiv tsev sab hauv ua rau lub cable muaj peev xwm rwb thaiv tsev hluav taws xob zoo dua. Ua haujlwm ua ke nrog cov txheej rwb thaiv tsev sab hauv, nws tsim cov txheej rwb thaiv tsev ob txheej, txo qhov kev pheej hmoo ntawm kev xau hluav taws xob thiab txhim kho kev nyab xeeb ntawm cov cable hauv cov chaw muaj hluav taws xob nyuaj. Hauv qee qhov chaw uas muaj kev xav tau rwb thaiv tsev siab heev, xws li chaw hloov pauv thiab cov chaw ua haujlwm khoom siv hluav taws xob meej, cov qauv rwb thaiv tsev PE ob txheej no tuaj yeem ua tau raws li cov qauv rwb thaiv tsev hluav taws xob nruj.
Kev Ruaj Ntseg Tshuaj thiab Cov Khoom Uas Muaj Dej Ntswg
Cov txheej PE rwb thaiv tsev sab nraud muaj kev ruaj khov zoo ntawm cov tshuaj lom neeg thiab tuaj yeem tiv taus kev puas tsuaj ntawm cov tshuaj lom neeg sab nraud. Tib lub sijhawm, nws kuj muaj qee yam khoom tiv taus dej noo, tiv thaiv cov dej noo kom tsis txhob nkag mus rau hauv sab hauv ntawm lub cable thiab zam kev poob qis ntawm kev ua haujlwm hluav taws xob lossis kev puas tsuaj rau cov txheej rwb thaiv tsev los ntawm qhov chaw noo noo, yog li ua rau lub neej ua haujlwm ntawm lub cable ntev dua.
(III) Cov Hlau Hlau Armor (SWA)
Kev Tiv Thaiv Kev Kho Tshuab
Cov hlau hlau tiv thaiv yog ib qho tseem ceeb ntawm kev tiv thaiv lub cable. Nws tuaj yeem tiv taus cov kev nyuaj siab sab nraud, xws li kev thawb cov khoom hnyav rau hauv av thaum lub sijhawm tso hauv av, kev sib tsoo nrog cov khoom siv hauv cov chaw lag luam, thiab kev cuam tshuam tsis tau xav txog thaum lub sijhawm tsim kho. Cov qauv tiv thaiv ruaj khov no tiv thaiv cov txheej rwb thaiv tsev thiab cov neeg hlau hauv lub cable, kom ntseeg tau tias lub cable tseem tuaj yeem ua haujlwm tau zoo hauv qhov chaw ua haujlwm hnyav.
Kev Ua Haujlwm Zoo ntawm Kev Tiv Thaiv Hluav Taws Xob
SWA muaj cov nyhuv tiv thaiv hluav taws xob tseem ceeb. Hauv cov cheeb tsam uas muaj kev cuam tshuam hluav taws xob, xws li ze cov khoom siv hluav taws xob loj thiab cov chaw sib txuas lus, cov hlau hlau tiv thaiv tuaj yeem thaiv kev cuam tshuam ntawm lub zog hluav taws xob sab nraud ntawm kev xa cov teeb liab hauv lub cable, thiab tseem tiv thaiv cov teeb liab sab hauv ntawm lub cable los ntawm kev tawm mus rau sab nraud kom cuam tshuam rau lwm yam khoom siv, kom ntseeg tau tias qhov tseeb thiab kev ruaj khov ntawm kev xa cov teeb liab.
(IV) Polyvinyl Chloride (PVC) Sab Nraud Sheath
Kev Tiv Thaiv Ib puag ncig Sab Nraud
Lub plhaub sab nraud PVC muab kev tiv thaiv sab nraud rau lub cable. Nws tuaj yeem tiv taus kev cuam tshuam ntawm ntau yam ib puag ncig, suav nrog ultraviolet radiation, tshuaj lom neeg corrosion, thiab mechanical abrasion. Hauv qhov chaw sab nraum zoov, lub plhaub sab nraud PVC tuaj yeem tiv thaiv kev laus ntawm ultraviolet rays hauv lub hnub ci rau cov khoom sab hauv ntawm lub cable; hauv qhov chaw tshuaj lom neeg, nws tuaj yeem tiv taus kev yaig ntawm cov tshuaj lom neeg; hauv cov chaw uas muaj kev sib txhuam ntau zaus, xws li sab hauv cov tais cable, nws tuaj yeem txo qhov kev puas tsuaj rau lub cable los ntawm kev siv tshuab abrasion.
Kev Txheeb Xyuas thiab Kev Sib Txawv Ua Haujlwm
Cov xim ntawm PVC sab nraud tuaj yeem hloov kho raws li qhov xav tau ntawm kev siv sib txawv, uas yog qhov tseem ceeb heev rau hauv cov kab ke sib txuas lus cable nyuaj. Cov sab nraud ntawm cov xim sib txawv tuaj yeem siv tau yooj yim los txheeb xyuas lub hom phiaj, qib voltage, lossis lub voj voog ntawm lub cable, thiab lwm yam, uas pab txheeb xyuas lub cable sai thiab raug thaum lub sijhawm teeb tsa, kev saib xyuas, thiab cov txheej txheem nrhiav qhov yuam kev, txhim kho kev ua haujlwm zoo.
