Lub Cable's "Invisible Armor": Lub Luag Haujlwm Tseem Ceeb ntawm Cov Txheej Qhwv

Cov cables yuav zoo li yooj yim rau sab nraud, tab sis sab hauv lawv tau tsim zoo li lub kaw lus tiv thaiv sib koom tes zoo. Tshaj li tus neeg coj thiab rwb thaiv tsev, feem ntau muaj ib lossis ntau txheej tsim los ntawm cov ntaub nplaum qhwv nruj nreem - qhov no hu ua txheej qhwv. Txawm hais tias tsis yooj yim pom, nws ua haujlwm ua lub cable "armor tsis pom," ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb, txhim khu kev qha, thiab kev ua haujlwm ntev.

1. Kev Tiv Thaiv Tshuab: Kab Tiv Thaiv Thawj Zaug Tiv Thaiv Cov Tub Rog Sab Nraud

Lub luag haujlwm tseem ceeb ntawm cov txheej qhwv yog kev tiv thaiv tshuab. Ib yam li cov cuab yeej ua rog uas cov tub rog thaum ub hnav, nws nyob ib puag ncig cov khoom sab hauv thiab tiv taus zoo:

Kev sib zog thiab kev cuam tshuam sab nraud:
Thaum lub sijhawm teeb tsa thiab tso cov xov hlau, cov xov hlau yuav raug kev nyuaj siab hauv av, kev nias los ntawm cov khoom nyob ib puag ncig, thiab txawm tias kev cuam tshuam los ntawm cov npoo ntse. Cov qauv qhwv nruj ntawm cov txheej qhwv pab faib cov khoom hnyav, tiv thaiv kev puas tsuaj ncaj qha lossis tho qhov rwb thaiv tsev hauv qab.

Kev tiv thaiv kev ntxhov siab sab hauv:
Thaum ib txoj hlua khi, tus neeg coj thiab cov rwb thaiv tsev yuav muaj kev ntxhov siab sib txawv thiab kev ntxhov siab sib txawv. Cov txheej qhwv no tiv thaiv cov khoom sab hauv, txo kev sib txhuam sab hauv thiab kev hnav uas tshwm sim los ntawm kev khoov thiab kev co ntau zaus, thiab txo qhov qaug zog ntawm cov khoom siv dhau sijhawm.

2. Kev Ruaj Ntseg ntawm Cov Qauv: Tswj Xyuas Kom Cov Cable "Zoo Tag Nrho"

Yuav kom ib txoj hlua hluav taws xob ua haujlwm tau zoo, nws cov txheej sab hauv yuav tsum sib txuas zoo thiab teeb tsa zoo. Cov txheej qhwv ua haujlwm zoo li "pob txha," muab kev ruaj khov tseem ceeb:

Kev tswj kom puag ncig:
Nws ua kom ntseeg tau tias cov xov hlau khaws cia ib lub voj voog zoo ib yam thoob plaws hauv kev tsim khoom thiab kev pabcuam lub neej. Qhov no yog qhov tseem ceeb rau cov txheej txheem armoring lossis sheath extrusion tom qab thiab tseem txhim kho kev du thaum lub sijhawm teeb tsa cable.

Tiv thaiv kev xoob:
Los ntawm kev khi lub hauv paus cable (ntau tus neeg hlau insulated), cov txheej qhwv tiv thaiv kev hloov pauv lossis xoob, tswj kev ncaj ncees thiab kev sib npaug.

3. Kev Txhim Kho Kev Ua Haujlwm Hluav Taws Xob: Ib Tus Khub Tseem Ceeb rau Kev Rwb Thaiv thiab Kev Tiv Thaiv

Nyob ntawm cov khoom siv siv, txheej qhwv tuaj yeem txhim kho qhov kev ua haujlwm hluav taws xob ntawm lub cable:

Kev rwb thaiv tsev pab:
Thaum cov ntaub ntawv xws li xov paj rwb, daim kab xev ntawv, lossisdaim kab xev polyester (mylar daim kab xev)Yog siv, txheej qhwv ua rau qhov deb ntawm creepage nce ntxiv thiab ua haujlwm ua txheej rwb thaiv tsev ntxiv, txhim kho ntxiv lub zog dielectric tag nrho thiab lub peev xwm tiv taus hluav taws xob.

Kev tswj kev ntxhov siab ntawm lub zog hluav taws xob:
Hauv cov xov hluav taws xob nruab nrab thiab siab, cov ntaub qhwv semi-conductive pab ua kom lub zog hluav taws xob sib npaug los ntawm kev tshem tawm qhov sib sau ua ke ntawm lub zog hluav taws xob uas tshwm sim los ntawm qhov tsis sib xws ntawm cov nplaim hluav taws xob. Qhov no ua rau tsis muaj kev tso tawm ib nrab thiab ua rau lub zog hluav taws xob ruaj khov thiab kev ntseeg siab ua haujlwm zoo dua.

Kev tiv thaiv hluav taws xob:
Qhwv nrog cov ntaub nplaum hlau (xws lidaim kab xev tooj liablos yog daim kab xev txhuas) yog ib qho ntawm cov hau kev tseem ceeb rau kev tsim ib txheej tiv thaiv. Cov "armor" hlau no zoo tiv thaiv cov teb hluav taws xob tsim sab hauv thaum tseem tsis suav nrog kev cuam tshuam hluav taws xob sab nraud, ua kom muaj kev ncaj ncees ntawm cov teeb liab thiab kev sib kis ruaj khov - tshwj xeeb tshaj yog qhov tseem ceeb rau kev tswj hwm thiab kev sib txuas lus cables.

Kev Txheeb Xyuas

Hauv kev xaus lus, txheej qhwv xov hlau tsis yog tsuas yog ib txheej "ntim khoom" yooj yim xwb. Nws yog ib qho khoom siv ntau yam uas muaj kev tiv thaiv tshuab, kev ruaj khov ntawm cov qauv, kev txhim kho hluav taws xob (xws li kev rwb thaiv tsev thiab kev tiv thaiv), thiab kev tiv thaiv ib puag ncig. Cov "tsom iav tsis pom" no ua haujlwm ntsiag to tom qab, ua rau cov xov hlau niaj hnub ua haujlwm tau zoo thiab muaj txiaj ntsig hauv cov chaw nyuaj thiab nyuaj thaum xa hluav taws xob thiab cov teeb liab tau zoo.
