RG59 coaxial cable yog ib qho 75 ohm impedance cable feem ntau yog siv rau kev xa cov teeb liab video. Kab lus no yuav muab cov ncauj lus kom ntxaws ntawm RG59 coaxial cable.
1, Qauv
Central conductor: feem ntau yog ib qho tooj liab hlau lossis tooj liab plated steel hlau.
Rwb thaiv tsev txheej: Polyethylene (PE) los yog lwm yam ntaub ntawv rwb thaiv tsev.
Shielding txheej: woven mesh los yog txhuas ntawv ci, siv los txo electromagnetic cuam tshuam.
Txheej txheej: PVC lossis lwm yam khoom siv tiv thaiv, muab kev tiv thaiv txhua yam.
2, Cov yam ntxwv hluav taws xob
Impedance: Tus qauv impedance yog 75 ohms, haum rau kev sib kis video.
Attenuation: Nws muaj cov teeb liab poob qis ntawm qhov tsawg zaus, tab sis raws li qhov zaus nce, qhov attenuation kuj nce raws li.
Bandwidth: Tsim nyog rau qhov ntau zaus ntawm 0 txog 3GHz, tshwj xeeb tshaj yog rau video thiab audio signals.
3, Cov yam ntxwv ntawm lub cev
Flexibility: Cov mos mos, yooj yim rau xaim thiab nruab.
Durability: Zoo hnav tsis kam thiab tensile zog.
Tus nqi ua tau zoo: Piv rau lwm hom coaxial cables xws li RG6, RG59 muaj tus nqi qis dua thiab tsim nyog rau cov ntawv thov siv nyiaj tsawg
4, Cov ntawv thov tshwj xeeb
RG59 coaxial cable yog dav siv nyob rau hauv cov nram qab no:
1. Closed Circuit Television System (CCTV)
RG59 yog ib qho ntawm feem ntau siv coaxial cables hauv CCTV systems, siv los txuas cov koob yees duab thiab cov cuab yeej saib xyuas. Nws tuaj yeem hloov kho siab - cov cim video zoo thiab yooj yim rau xaim hauv cov tsev vim nws qhov yooj yim.
2. Cable TV (Cable TV)
Hauv qee qhov me me lossis uas twb muaj lawm cable TV faib tshuab, RG59 yog siv los xa cov xov xwm tshaj tawm los ntawm cov kav hlau txais xov lossis satellite txais mus rau cov neeg siv TV. Txawm hais tias tam sim no muaj kev nyiam siv RG6 cables nrog kev ua tau zoo dua, qee zaum, RG59 tseem yog qhov kev xaiv siv tau.
3. Kev tshaj tawm thiab kev tshaj lij audio thiab video
Ntxiv nrog rau cov teeb liab video, RG59 kuj tuaj yeem siv los xa cov suab paj nruag thiab ua haujlwm raws li lub suab sib luag hauv qee qhov chaw suab nrov. Tsis tas li ntawd, nws feem ntau tshwm sim hauv wireless, kev sib txuas lus luv luv thiab lwm lub sijhawm.
4. Kev lom zem hauv tsev
Hauv cov chaw ua yeeb yam hauv tsev, RG59 tuaj yeem siv los txuas cov khoom siv xws li DVD players, game consoles, Blu ray players, thiab lwm yam rau TV lossis lwm yam khoom siv kom ua tiav siab -txhais video thiab lub suab sib kis.
5. Cov ntaub ntawv luv luv kis tau tus mob
Txawm hais tias tsis tshua muaj tshwm sim, RG59 tseem tuaj yeem siv rau kev xa cov ntaub ntawv hauv cov chaw hauv cheeb tsam hauv cheeb tsam hauv cov xwm txheej tshwj xeeb, tshwj xeeb tshaj yog thaum cov nqi qis - yuav tsum muaj kev daws teeb meem.
6, Kev ceev faj thaum siv
1). Tsis txhob khoov ntau dhau
Txawm hais tias RG59 yog qhov muag muag, nws tseem yuav tsum tau zam dhau kev khoov lossis sib tw, uas tuaj yeem ua rau tus neeg xyuas pib tawg lossis tawg puas tsuaj, yog li cuam tshuam cov teeb liab zoo.
2). Yog xaiv lub connector
Siv qhov tsim nyog BNC lossis F- hom connectors thiab xyuas kom muaj kev ruaj ntseg thiab txhim khu kev qha. Cov khoom sib txuas tsis raug yuav ua rau cov teeb liab xau lossis kev sib cuag tsis zoo, yog li cuam tshuam rau kev sib kis tau zoo.
3) Waterproof thiab noo noo - pov thawj kev kho mob
Yog tias tau teeb tsa sab nraum zoov lossis hauv qhov chaw ntub dej, yuav tsum tau ntsuas cov dej tsis zoo, xws li siv cov pob qij txha tsis muaj dej los yog cov ntaub nplaum sib khi, kom tsis txhob ya raws los ntawm kev nkag mus thiab ua rau luv luv lossis lwm yam teeb meem.
4). Shielding txheej grounding
Xyuas kom meej tias cov txheej thaiv thaiv tau zoo hauv av, uas tuaj yeem txhim kho kev tiv thaiv - muaj peev xwm cuam tshuam thiab kev nyab xeeb. Cov kab hluav taws xob tsis zoo yuav dhau los ua cov kab hluav taws xob hluav taws xob lossis hluav taws xob, ua rau cov khoom puas tsuaj.
5). Ntev txwv
Xav txog qhov attenuation yam, sim siv cov cables luv dua kom paub meej cov teeb liab zoo. Rau qhov ntev - kis tau tus mob nyob deb, nws yuav tsum tau txiav txim siab siv ntau dua specifications cables los yog txhim kho cov teeb liab los ntawm amplifiers.
6). Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua
Tsis tu ncua tshuaj xyuas cov cables rau kev puas tsuaj rau lub cev thiab cov pob qij txha xoob. Khaws cov khoom txuas thiab fittings kom huv si kom tsis txhob muaj plua plav thiab av sib xyaw los ntawm kev cuam tshuam cov teeb liab.
7). Sib piv impedance
Xyuas kom meej tias cov tswv yim thiab cov zis impedance ntawm tag nrho cov khoom siv txuas nrog yog 75 ohms kom tsis txhob cuam tshuam qhov poob thiab teeb liab distortion
