Hauv kev lag luam niaj hnub thiab lub neej niaj hnub, cables nyob txhua qhov chaw, kom ntseeg tau tias kev sib kis tau zoo ntawm cov ntaub ntawv thiab lub zog. Koj paub ntau npaum li cas txog cov "kev sib raug zoo" no? Kab lus no yuav coj koj mus tob rau hauv lub ntiaj teb sab hauv ntawm cables thiab tshawb nrhiav qhov tsis meej ntawm lawv cov qauv thiab cov ntaub ntawv.
Cable qauv muaj pes tsawg leeg
Cov yam ntxwv ntawm cov khoom siv hlau thiab cable feem ntau tuaj yeem muab faib ua plaub yam tseem ceeb ntawm tus neeg xyuas pib, rwb thaiv tsev, thaiv thiab tiv thaiv txheej, nrog rau cov khoom ntim thiab cov kabmob.
1. Tus coj
Tus neeg xyuas pib yog qhov tseem ceeb ntawm cov ntaub ntawv xa tawm tam sim no lossis electromagnetic yoj. Cov khoom siv hluav taws xob feem ntau yog ua los ntawm cov hlau tsis muaj hlau nrog cov khoom siv hluav taws xob zoo xws li tooj liab thiab txhuas. Cov kab hluav taws xob kho qhov muag siv hauv kev sib txuas lus kho qhov muag siv cov fiber ntau optical ua tus neeg xyuas pib.
2. Txheej rwb thaiv tsev
Cov txheej rwb thaiv tsev npog lub periphery ntawm cov hlau thiab ua raws li hluav taws xob rwb thaiv tsev. Cov ntaub ntawv insulating feem ntau yog Polyvinyl chloride (PVC), Cross-linked polyethylene (XLPE), fluorine plastics, Roj hmab khoom, Ethylene propylene roj hmab khoom, Silicone roj hmab rwb thaiv tsev khoom. Cov ntaub ntawv no tuaj yeem ua tau raws li cov kev xav tau ntawm cov khoom siv hlau thiab cable rau kev siv sib txawv thiab kev xav tau ib puag ncig.
3. Sheath
Cov txheej txheem tiv thaiv muaj kev tiv thaiv ntawm cov txheej txheem rwb thaiv tsev, tsis muaj dej, nplaim hluav taws thiab corrosion resistant. Cov ntaub ntawv sheath yog cov roj hmab, yas, xim, silicone thiab ntau yam khoom siv fiber ntau. Cov hlau sheath muaj kev ua haujlwm ntawm kev tiv thaiv kev tiv thaiv thiab kev tiv thaiv, thiab yog dav siv nyob rau hauv lub hwj chim cables uas tsis zoo noo noo tiv thaiv kom tsis txhob ya raws thiab lwm yam teeb meem los ntawm kev nkag mus rau hauv lub cable rwb thaiv tsev.
4. Kev tiv thaiv txheej
Shielding txheej cais cov electromagnetic teb sab hauv thiab sab nraud cables los tiv thaiv cov ntaub ntawv to thiab cuam tshuam. Cov ntaub thaiv npog muaj xws li Metallized ntawv, Semiconductor daim kab xev, Aluminium ntawv nyiaj Mylar daim kab xev,Copper foil Mylar daim kab xev, Copper daim kab xev thiab Braided tooj liab hlau. Cov txheej thaiv kev tiv thaiv tuaj yeem teeb tsa nruab nrab ntawm sab nraud ntawm cov khoom lag luam thiab kev sib koom ua ke ntawm txhua tus khub ib kab lossis multilog cable los xyuas kom meej tias cov ntaub ntawv xa mus rau hauv cov khoom siv cable tsis xau thiab tiv thaiv kev cuam tshuam sab nraud electromagnetic yoj.
5. Filling qauv
Cov qauv sau ua rau sab nraud ntawm txoj kab nruab nrab ntawm lub voj voog, cov qauv ruaj khov, thiab sab hauv muaj zog. Cov ntaub ntawv sau ntau suav nrog Polypropylene daim kab xev, Non-woven PP hlua, Hemp hlua, thiab lwm yam. Cov qauv filling tsis tsuas yog pab qhwv thiab nyem lub hnab thaum lub sijhawm tsim khoom, tab sis kuj lav cov khoom siv kho tshuab thiab ua haujlwm ntev ntawm cov khoom siv.
6. Tensile ntsiab
Tensile ntsiab tiv thaiv lub cable los ntawm nro, cov ntaub ntawv uas yog Steel daim kab xev, hlau hlau, Stainless hlau ntawv ci. Hauv fiber ntau optic cables, tensile cov ntsiab lus tseem ceeb tshwj xeeb los tiv thaiv cov fiber ntau los ntawm kev cuam tshuam los ntawm kev nro thiab cuam tshuam rau kev sib kis. Xws li FRP, Aramid fiber ntau thiab lwm yam.
Cov ntsiab lus ntawm cov khoom siv hlau thiab cable
1. Hlau thiab cable manufacturing kev lag luam yog cov khoom tiav thiab sib dhos kev lag luam. Cov ntaub ntawv suav nrog 60-90% ntawm tag nrho cov nqi tsim khoom. Cov khoom qeb, ntau yam, kev ua haujlwm siab, kev xaiv cov khoom siv cuam tshuam rau cov khoom lag luam thiab lub neej.
2. Cov ntaub ntawv siv rau cov khoom siv cable tuaj yeem muab faib ua cov khoom siv hluav taws xob, cov ntaub ntawv insulating, cov ntaub ntawv tiv thaiv, cov ntaub thaiv npog, cov ntaub ntawv sau, thiab lwm yam, raws li cov khoom siv thiab kev ua haujlwm. Cov ntaub ntawv thermoplastic xws li polyvinyl chloride thiab polyethylene tuaj yeem siv rau rwb thaiv tsev lossis sheathing.
3. Kev siv ua haujlwm, daim ntawv thov ib puag ncig thiab kev siv cov khoom siv cable muaj ntau haiv neeg, thiab qhov sib xws thiab cov yam ntxwv ntawm cov khoom sib txawv. Piv txwv li, txheej rwb thaiv tsev ntawm high-voltage fais fab cables yuav tsum muaj hluav taws xob rwb thaiv tsev ua tau zoo, thiab cov hluav taws xob qis qis yuav tsum tau siv tshuab thiab huab cua tsis kam.
4. Cov khoom siv ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov khoom, thiab cov txheej txheem cov txheej txheem thiab cov khoom tiav tiav ntawm cov qib sib txawv thiab cov qauv sib txawv heev. Cov chaw tsim khoom lag luam yuav tsum siv cov kev tswj xyuas nruj.
Los ntawm kev nkag siab txog cov qauv tsim thiab cov yam ntxwv ntawm cov khoom siv cable, cov khoom siv cable tuaj yeem xaiv tau zoo dua thiab siv.
Ib lub ntiaj teb hlau thiab cable raw khoom muab cov ntaub ntawv raw saum toj no nrog kev ua haujlwm siab. Cov qauv pub dawb yog muab rau cov neeg siv khoom los kuaj xyuas kom ntseeg tau tias qhov kev ua tau zoo tuaj yeem ua tau raws li cov neeg siv khoom xav tau.
