Feem ntau hais lus, AC fais fab kab yog tsim los ntawm high-voltage AC fais fab kab. Vim muaj qhov hluav taws xob siab, cov neeg ua haujlwm pov thawj kev nyab xeeb tuaj yeem tsim tau. DC kab yeej dhau los ntawm qhov tsis tshua muaj hluav taws xob DC, yog li AC kab tsis nruj rau kev nyab xeeb. Txawm li cas los xij, vim yog vim li cas kev nyab xeeb, txhua lub teb chaws xav tau ntawv pov thawj kev nyab xeeb.
Tus qauv ntawm lub koob yees duab muaj zog cable network cable yog dab tsi?
Cov qauv ntawm kev lag luam lub koob yees duab fais fab cable network cable tsis yog txoj hauv kev, tab sis nws tsis yooj yim pom ntawm qhov chaw. Yuav kom kawm txog cov hlua hluav taws xob zoo, qee qhov chaw yuav tsum nkag siab txog cov qauv ntawm cov hlua hluav taws xob.
Cov qauv ntawm kev lag luam lub koob yees duab fais fab kab network cable feem ntau suav nrog cov ntaub qhwv sab nrauv, sab hauv sheath, tus neeg xyuas pib, tooj liab, txhuas hlau thiab lwm yam kis tau tus mob.
Cov khoom siv sab nraud
Lub sheath, tseem hu ua zaj duab xis tiv thaiv, yog lub sheath sab nraum lub hwj chim kab. Nws muaj cov yam ntxwv muaj zog xws li kub tsis kam, tsis kub tsis kam, ntuj lub teeb cuam tshuam tsis kam, kev ua haujlwm dhau los, kev pabcuam lub neej, khoom siv, thiab lwm yam.
Internal tiv thaiv txheej
Sab hauv thiab sab nraud ntev, tseem hu ua insulating sheath, yog ib qho tseem ceeb ntawm cov qauv nruab nrab ntawm cov kab hluav taws xob. Raws li lub npe implies, lub hom phiaj tseem ceeb ntawm insulating sheath yog rwb thaiv tsev. Txhawm rau kom muaj kev nyab xeeb ntawm hluav taws xob ntawm cov kab hluav taws xob thiab tiv thaiv kom tsis txhob muaj qhov sib txawv ntawm tooj liab thiab huab cua, cov khoom siv insulating sheath yuav tsum mos thiab tuaj yeem ua kom zoo rau hauv nruab nrab txheej.
tooj liab
Tooj hlau yog qhov tseem ceeb ntawm cov xaim hluav taws xob. tooj liab hlau yog tsuas yog cov cab kuj ntawm tam sim no thiab voltage. Qhov ntom ntawm tooj liab xaim ncaj qha cuam tshuam rau qhov zoo ntawm lub zog xaim. Cov khoom siv ntawm lub zog xaim kuj yog ib qho tseem ceeb hauv kev tshuaj xyuas zoo, thiab qhov ntau thiab kev hloov pauv ntawm cov hlau tooj liab kuj yog ib qho ntawm cov khoom yuav tsum tau txiav txim siab.
Internal tiv thaiv txheej
Cov khoom siv nruab nrab ntawm cov txheej thaiv thiab cov txheej txheem tseem ceeb ntawm cov ntaub qhwv sab hauv feem ntau yog PVC yas lossis polyethylene yas. Kuj tseem muaj cov khoom siv hluav taws xob tsis muaj halogen tsawg. Raws li cov txheej txheem kev cai, xyuas kom meej tias cov khoom siv rwb thaiv tsev tsis tiv nrog dej, huab cua lossis lwm yam khoom, thiab tiv thaiv kev puas tsuaj ntawm cov khoom siv rwb thaiv tsev thiab cov khoom siv rwb thaiv tsev.
