Rau yam uas yuav tsum xav txog rau industrial CCTV coax cable xaiv

Xaiv qhov tsis raug coaxial cable rau lub kaw xov tooj cua kaw (CCTV) tuaj yeem ua rau cov teeb liab sib kis tau zoo thiab tsis zoo. Xav txog cov khoom siv yooj yim xws li kev tiv thaiv, hom RG, thiab lub tsho muaj pes tsawg leeg thaum xaiv ib coaxial cable.

Coaxial cable yog tsim los xa cov video ntau zaus nrog qhov tsawg kawg nkaus attenuation lossis distortion. Xaiv cov coaxial cable tsis raug rau lub kaw xov tooj cua kaw (CCTV) tuaj yeem cuam tshuam cov teeb liab kis tau tus mob thiab tso cai rau sab nraud xov tooj cua cuam tshuam (RFI), uas yuav ua rau cov duab tsis zoo lossis siv tsis tau. Nws muaj rau lub hauv paus khoom ntawm coax cable, uas tuaj nyob rau hauv ntau hom kev tsim kho thiab cov ntaub ntawv:

1. Kev tsim kho hauv nruab nrab - Muaj ob hom kev tsim kho: cov khoom siv tooj liab thiab tooj liab coated steel core. Cov tooj liab coated steel yog tsis tshua kim thiab feem ntau yog ib tug muaj zog cable. Txawm li cas los xij, nws yuav txo qis qis ntawm cov teeb liab video thiab tsis pom zoo.

2. Center conductor impedance - Ntau lub tshuab CCTV tau tshaj 75 Ohm cable. Txawm li cas los xij, muaj lwm cov qauv impedance muaj. Txiav txim siab seb qhov impedance cable xav tau raws li qhov system hardware.

3. Dielectric Insulator - Cov khoom siv insulating nyob ib puag ncig ntawm qhov chaw tus neeg xyuas pib yuav muaj kev cuam tshuam rau lub peev xwm, impedance, attenuation thiab tshaj tawm ntawm cov teeb liab tawm. Kev siv cov insulator xws li FEP lossis polyethylene yog pom zoo. Tsis txhob cuam tshuam ntau dhau los ntawm cov khoom siv; tag nrho cable specs yuav yog ib qho kev xav ntawm lub insulator nyob rau hauv lub cable. Xyuas kom tseeb tias txhua tus yam ntxwv ntawm cov kab lus hais saum toj no yog nyob rau hauv ib qho kev pom zoo rau daim ntawv thov.

4. Shielding - Lub hom phiaj ntawm daim ntaub thaiv yog los muab kev tiv thaiv kev cuam tshuam sab nraud, uas tuaj yeem cuam tshuam cov teeb liab video, thiab muab DC tsis kam rau hauv av. Cov ntaub thaiv npog zoo yuav tsum yog tooj liab liab thiab muaj 95% lossis zoo dua braid npog; dab tsi tsawg yog feem ntau tsis pom zoo rau CCTV.

5. Jacket muaj pes tsawg leeg - Lub tsho yuav tsum tau txiav txim siab los ntawm ib puag ncig uas yuav raug teeb tsa. Tib lub hauv paus ntsiab lus siv ntawm no nrog rau kev teeb tsa hluav taws xob cable. Sab hauv / sab nraum zoov, ncaj qha faus, tshav ntuj tiv taus, puas ntsoog, plenum thiab lwm yam. Ua raws li National Electrical Code (NEC) thiab cov cai tswj hwm hauv zos rau cov khoom no.

6. RG Hom - Coax cable muaj nyob rau hauv ntau hom RG sib txawv nrog qhov sib txawv tshaj plaws ntawm lawv yog qhov kev cia siab ntawm lub teeb liab. Cov hauv qab no yog cov 75 Ohm cable uas nrov tshaj plaws thiab lawv cov kev siv tau nyob deb li cas:

RG-179 (500 ft)

RG-59 (750 txog 1000 ft)

RG-6 (1000-1500 ft)

RG-7 (1500 txog 2200 ft)

RG-11 (2200 txog 3000 ft).
