Feature ntawm coaxial cable

Coaxial cableyog ib hom kab mob siab rau cov ntaub ntawv thiab teeb liab kis tau tus mob, muaj xws li ib tug nruab nrab conductor, rwb thaiv tsev txheej, mesh shield txheej, txheej rwb thaiv tsev txheej thiab sheath txheej.Lub hauv paus tus neeg xyuas pib ntawm coaxial cable yog cov hlau hlau, feem ntau yog ua los ntawm tooj liab lossis txhuas, txheej insulating feem ntau yog ua los ntawm polypropylene lossis polyethylene, thiab cov txheej thaiv mesh yog npog los ntawm cov txheej insulating thiab yog ua los ntawm tooj liab hlau lossis txhuas ntawv ci. .Coaxial cableyog dav siv hauv computer networks, TV teeb liab kis tau tus mob, kev ruaj ntseg systems, xov tooj cua chaw nres tsheb thiab lwm yam teb.

Cov hauv qab no yog ib co ntawm cov yam ntxwv tseem ceeb ntawmcoaxial kab:

 1. Anti-electromagnetic cuam tshuam: Sab hauv mesh shielding txheej ntawm coaxial cable tuaj yeem tiv thaiv kev cuam tshuam sab nraud electromagnetic thiab xyuas kom ruaj khov thiab kev ntseeg siab ntawm cov teeb liab kis tau tus mob.

 2. Loj muaj peev xwm: Lub hauv paus neeg xyuas pib ntawm lubcoaxial kabyog cov hlau hlau, zoo conductivity, muaj peev xwm loj, tuaj yeem xa cov teeb liab ntau zaus.

 3. Lub teeb liab kis tau tus mob ntev: lub teeb liab kis tau tus mob nyob deb ntawm coaxial cable yog deb tshaj li ntawm cov kab hluav taws xob dav dav, thiab qhov kis tau tus mob feem ntau yog nyob ntawm ob peb mais mus rau kaum ob mais.

 4.Sheath txheej tiv thaiv: coaxial cable txheej txheej rwb thaiv tsev thiab txheej txheej txheej tuaj yeem tiv thaiv cov qauv hauv nruab nrab thiab txuas ntxiv lub neej kev pab cuam ntawm cable.

 5.Cov yam ntxwv impedance: lub ntsiab ntawm cov coaxial cable yog lub puab thiab sab nraud ob conductors, tam sim no los ntawm tus neeg xyuas pib yuav tsim kev tiv thaiv thiab inductance, thiab conductance thiab capacitance ntawm cov conductors yuav raug generated, thiab faib raws txoj kab, kuj hu ua. muab luam tawm.

Yog li ntawd, qhov tseeb tus yam ntxwv impedance ntawm coaxial cable yuav siab tshaj qhov theoretical tus nqi thaum txuas cov zaub system.Yog li ntawd, txhawm rau zam lub teeb pom kev muaj peev xwm xav tau tsim los ntawm qhov xwm txheej no thiab ua kom muaj kev sib kis tau zoo tshaj plaws, lub davhlau ya nyob twg load impedance yuav tsum tau ua raws li cov yam ntxwv ntawm cable impedance kom ntau li ntau tau.

 6.Attenuation yam ntxwv: Lub attenuation yam ntxwv ntawmcoaxial kabfeem ntau txheeb xyuas los ntawm qhov attenuation tas li, uas yog sib npaug rau decibels ntawm lub teeb liab attenuation ntawm tam sim no ib chav tsev ntev.Lub attenuation tas li ntawm cov coaxial cable yog proportional rau lub zaus khiav hauj lwm ntawm lub teeb liab, uas yog, qhov ntau dua qhov zaus generated, qhov ntau dua qhov attenuation tas li, qhov tsawg zaus, qhov me me qhov attenuation tas li.

 Nws yuav tsum tau muab sau tseg tias hom thiab specifications ntawmcov kab mob coaxialsib txawv raws li qhov sib txawv daim ntawv thov scenarios thiab xav tau kev pab.Thaum xaiv ib lub coaxial cable, nws yog ib qho tsim nyog yuav tau xav txog qhov zaus ntawm cov teeb liab kis tau tus mob, qhov kev sib kis deb, qhov chaw siv, hom kev sib txuas thiab lwm yam, thiaj li xaiv cov qauv tsim nyog thiab cov lus qhia tshwj xeeb.
