Hauv kev lag luam niaj hnub thiab txhua hnub, cov kab ke txhua qhov chaw, ua kom muaj kev sib kis tau zoo ntawm cov ntaub ntawv thiab lub zog. Koj tau paub ntau npaum li cas txog cov "zais ties"? Kab lus no yuav ua rau koj tob rau hauv lub ntiaj teb sab hauv thiab tshawb txog kev tsis paub txog ntawm lawv cov qauv thiab cov ntaub ntawv.
Cable qauv sib xyaw
Cov txheej txheem hlau thiab cov khoom lag luam cable tuaj yeem muab faib rau hauv plaub lub ntsiab qauv ntawm tus neeg saib xyuas, kev thaiv thiab cov khoom tiv thaiv thiab cov kabmob.
1. Tus neeg saib xyuas
Cov neeg ua yeeb coj ua yog lub tseem ceeb ntawm kev tam sim no lossis electromagnetic wood cov ntaub ntawv kis tau. Cov ntaub ntawv coj ua feem ntau ua los ntawm cov uas tsis muaj hlau uas tsis muaj hlau nrog cov hluav taws xob zoo xws li tooj liab thiab txhuas. Lub khoos phis tawm kho qhov muag siv hauv kev sib txuas lus kho qhov muag siv lub fiber ntau yam uas yog tus neeg xyuas.
2. Rwb thaiv txheej txheej
Cov rwb thaiv tsev txheej npog lub periphery ntawm cov hlau thiab ua raws li rwb thaiv hluav taws xob. Cov ntaub ntawv insulating yog polyvinyl chloride (PVC), Hla-Txuas Polyethylene (XLPE), Fluorine Plastics, cov khoom siv roj hmab, ethylene propylene roj hmab cov ntaub ntawv, silicone roj hmab rwb thaiv tsev khoom. Cov ntaub ntawv no tuaj yeem ua tau raws li cov kev xav tau ntawm cov hlau thiab cov khoom lag luam cable rau cov kev siv sib txawv thiab ib puag ncig cov cai.
3. Sheath
Cov txheej tiv thaiv muaj cov nyhuv tiv thaiv ntawm cov txheej txheem rwb thaiv tsev, waterproof, nplaim taws retardant thiab corrosion resistant. Cov ntaub muag tsuas yog roj hmab, yas, pleev xim, silicone thiab ntau yam fiber ntau. Cov hlau sheath muaj txoj haujlwm ntawm kev tiv thaiv txhua yam thiab yog siv dav hauv kev ua tsis zoo thiab lwm yam teeb meem los ntawm kev nkag mus rau hauv cable rwb thaiv tsev.
4. Cov Khoom Siv Hluav Taws Xob
Kev thaiv cov khaubncaws sab nraud hluav taws xob cais tawm hauv hluav taws xob hauv thiab sab nraud los tiv thaiv cov ntaub ntawv tas thiab cuam tshuam. Cov ntaub ntawv tiv thaiv cov ntaub ntawv suav nrog metallized ntawv, semiconductor ntawv daim ntaub nplaum daim kab xev, txhuas ntawv ci daim duab mars daim kab xev,Tooj liab ntawv ci mylar daim kab xev, Tooj liab daim kab xev thiab braided tooj liab xaim. Daim thaiv npog yuav tuaj yeem tsim nruab nrab ntawm cov khoom thiab pawg ntawm txhua tus khub ib khub lossis cov khoom sib kis hauv cov khoom siv cable tsis yog xau thiab tiv thaiv kev cuam tshuam rau sab nraud.
5. Sau qauv qauv
Cov qauv sau ua cov cheeb tsam sab nraud ntawm txoj hlua cable, tus qauv yog ruaj khov, thiab sab hauv yog muaj zog. Cov ntaub ntawv ntim ntim ntim xws li polypropylene daim kab xev, hemp ntawm cov qauv tsim, tab sis kuj tau lees paub cov cuab yeej tsim khoom, thiab tuaj yeem lav cov cuab yeej ua haujlwm thiab tsis tuaj yeem lees paub cov cuab yeej ua haujlwm thiab cov khoom siv hluav taws xob ntawm kev siv.
6. Tensile ntsiab
Cov khoom siv tensile tiv thaiv lub cable los ntawm nro, cov ntaub ntawv cov khoom siv yog cov kab xev hlau, hlau xaim, stainless hlau ntawv nyiaj. Nyob rau hauv cov xaim hluav taws xob muaj optic cov xaim me me, cov ncauj tensile tshwj xeeb yog qhov tseem ceeb rau kev tiv thaiv cov fiber ntau los ntawm kev cuam tshuam los ntawm nro thiab cuam tshuam rau kev kis tau. Xws li frp, aramid fiber ntau thiab lwm yam.
Hlau thiab cable cov ntaub ntawv ntsiab lus
1. Hlau thiab cable tsim kev lag luam yog ib qho khoom tiav thiab kev ua haujlwm sib dhos. Cov ntaub ntawv tus account rau 60-90% ntawm cov nqi tsim khoom tag nrho. Cov ntaub ntawv qeb, ntau yam, kev ua tau zoo yuav tsum muaj, cov ntaub ntawv xaiv cuam tshuam rau cov khoom lag luam thiab lub neej.
2. Cov ntaub ntawv siv rau cov khoom cable tuaj yeem faib ua cov ntaub ntawv ua haujlwm, cov ntaub ntawv insulating, ntim cov ntaub ntawv, thiab lwm yam, raws li kev siv cov ntu thiab cov haujlwm. Thermopoplastic ntaub ntawv xws li polyvinyl chloride thiab polyethylene tuaj yeem siv rau rwb thaiv tsev lossis sheathing.
3. Siv kev ua haujlwm, ib puag ncig kev thov thiab siv cov khoom lag luam ntawm cov khoom lag luam cable muaj ntau haiv neeg, thiab cov yam ntxwv ntawm cov ntaub ntawv sib txawv. Piv txwv li, cov rwb thaiv tsev txheej ntawm high-voltage zog yuav tsum tau hluav taws xob rwb thaiv tsev kev ua tau zoo, thiab cov hluav taws xob tsawg yuav tsum tau kho tshuab thiab huab cua tsis kam.
4. Khoom siv lub luag haujlwm tseem ceeb hauv cov khoom lag luam, thiab cov txheej txheem kev ua tiav kev ua tau zoo ntawm cov qib sib txawv thiab cov qauv sib txawv heev. Tsim kev lag luam yuav tsum muaj kev tswjhwm nruj kom nruj.
Los ntawm kev nkag siab cov qauv kev sib xyaw thiab cov khoom siv ntawm cov xaim, cable khoom tuaj yeem xaiv tau zoo thiab siv.
Ib lub ntiaj teb hlau thiab cable raw khoom tsum muab cov ntaub ntawv raw rau cov nqi siab. Cov qauv pub dawb yog muab rau cov neeg siv khoom lag luam kom ntseeg tau tias kev ua tau zoo tuaj yeem ntsib cov neeg siv khoom xav tau.
