Nrog rau kev nthuav dav ntxiv ntawm kev lag luam hluav taws xob, cov ntaub ntawv kev sib txuas lus kev lag luam thiab lwm yam kev lag luam, qhov kev thov rau cov xov hlau thiab cables tseem yuav nce sai, thiab cov kev xav tau ntawm cov xov hlau thiab cables yuav nruj dua.Muaj ntau hom ntawm lawv, tsis yog tsuas yog xaim thiab cable rau hluav taws xob hauv tsev, tab sis kuj xaim thiab cable rau kev lag luam tshwj xeeb, thiab tseem muaj ib lub cable hu ua "coaxial cable".Yog li, koj puas paub txog qhov "coaxial cable"?Txawm hais tias koj tsis paub, nws tsis muaj teeb meem, vim hais tias tom ntej no, tus editor yuav qhia rau koj.
Lub npe hu ua "coaxial cable", raws li lub npe implies, yog ib tug cable nrog ob concentric conductors, thiab tus neeg xyuas pib thiab lub shielding txheej sib koom tib axis.Tshwj xeeb, coaxial cable yog tsim los ntawm tooj liab hlau conductors cais los ntawm cov ntaub ntawv insulating.Sab nraum txheej txheej ntawm rwb thaiv tsev yog lwm txheej ntawm lub nplhaib conductor thiab nws cov insulator, ces tag nrho cov cable yog qhwv los ntawm ib tug sheath ntawm PVC los yog Teflon khoom.
Pom qhov no, koj yuav paub tias dab tsi yog ib qho ntawm qhov sib txawv ntawm coaxial cables thiab cables zoo tib yam.Tom qab tag nrho, cov kab hluav taws xob zoo tib yam yog cov hlua zoo li cov hlua uas sib tw los ntawm ob peb lossis ob peb pawg ntawm cov xov hlau (tsawg kawg yog ob ntawm txhua pawg).Txhua txheej ntawm cov xov hlau yog insulated los ntawm ib leeg thiab feem ntau twisted nyob ib ncig ntawm ib qho chaw, nrog ib tug heev insulating npog npog tag nrho sab nraum.
Tam sim no peb nkag siab lub ntsiab lus ntawm coaxial cable, cia peb nkag siab nws hom, uas yog: raws li kev faib tawm sib txawv, coaxial cables tuaj yeem muab faib ua ntau hom.Piv txwv li, raws li lawv txoj kab uas hla, coaxial cables tuaj yeem muab faib ua coaxial cable tuab thiab nyias coaxial cable;Raws li lawv cov kev siv sib txawv, coaxial cable tuaj yeem muab faib ua baseband coaxial cable thiab broadband coaxial cable.
Piv nrog rau cov cables zoo tib yam, muaj tsawg dua hom coaxial cables.Tom qab tag nrho, cov kab hluav taws xob zoo tib yam suav nrog cov hluav taws xob cables, tswj cables, them cables, shielded cables, kub kub cables, computer cables, teeb liab cables, coaxial cables, hluav taws-resistant cables, thiab marine cables., mining cables, aluminium alloy cables, thiab lwm yam, yog siv los txuas circuits, cov khoom siv hluav taws xob, thiab lwm yam, uas kuj yog qhov sib txawv ntawm coaxial cables thiab cables zoo tib yam.
Tom qab tham txog cov hom coaxial cables, peb yuav tsum to taub nws cov yam ntxwv ua hauj lwm, uas yog, coaxial cables ua alternating tam sim no es tsis txhob ntawm ncaj qha tam sim no, uas txhais tau hais tias cov kev taw qhia ntawm tam sim no yuav rov qab ob peb zaug ib ob.Cov qauv, los ntawm sab hauv mus rau sab nraud, yog lub hauv paus tooj liab hlau (ib leeg-strand khoom hlau los yog ntau txoj hlua khi hlua), yas insulator, mesh conductive txheej thiab hlau sheath.Lub hauv paus tooj liab hlau thiab cov mesh conductive txheej tsim ib lub voj tam sim no, uas kuj yog qhov txawv ntawm cov kab hluav taws xob zoo tib yam.Tom qab tag nrho, cov kab hluav taws xob zoo tib yam tuaj yeem muab faib ua DC cables thiab AC cables raws li qhov system ntawm photovoltaic fais fab nroj tsuag.Qhov ntawd yog hais tias, cov kab hluav taws xob zoo tib yam siv DC lossis AC lub zog, uas DC lub zog xa tawm ntau dua.
Zoo, cov saum toj no yog cov kev taw qhia ntawm coaxial cable, tshwj xeeb tshaj yog cov kev taw qhia ntawm qhov sib txawv ntawm coaxial cable thiab zoo tib yam cable, kuv vam tias sawv daws to taub.
