Zvinoumba coaxial tambo

Coaxial tamboimhando yetambo yakatsaurirwa kune data uye chiratidzo chekufambisa, inosanganisira yepakati conductor, insulation layer, mesh shield layer, yekunze insulation layer uye sheath layer.Iyo yepakati conductor yecoaxial tambo isimbi yesimbi, inowanzo gadzirwa nemhangura kana aluminium, iyo insulating layer inowanzo gadzirwa ne polypropylene kana polyethylene, uye mesh inodzivirira layer yakavharwa ne insulating layer uye inogadzirwa newaya yemhangura kana aluminium foil. .Coaxial tamboinoshandiswa zvakanyanya mumakombuta network, kutapurirana chiratidzo cheTV, masisitimu ekuchengetedza, zviteshi zveredhiyo uye mamwe minda.

Izvi zvinotevera zvimwe zvezvinhu zvikuru zvecoaxial tambo:

 1. Anti-electromagnetic interference: Iyo yemukati mesh shielding layer ye coaxial tambo inogona zvinobudirira kurwisa kunze kwemagetsi kukanganiswa uye kuve nechokwadi kugadzikana uye kuvimbika kwekufambiswa kwechiratidzo.

 2. Huru hukuru: Iyo yepakati conductor yecoaxial tamboiwaya yesimbi, yakanaka conductivity, yakakura kugona, inogona kutumira masaini akakwira frequency.

 3. Chinhambwe chekufambisa kwemasaini marefu: chinhambwe chekufambisa kwechiratidzo checoaxial tambo iri kure kupfuura iyo yetambo yeruzhinji, uye nhambwe yekufambisa inowanzobva pamakiromita mashoma kusvika makumi emakiromita.

 4.Sheath layer dziviriro: coaxial tambo yekunze insulation layer uye sheath layer inogona kudzivirira zvinobudirira iyo cable centre chimiro uye kuwedzera hupenyu hwesevhisi tambo.

 5.Characteristic impedance: chikamu chikuru cheiyo coaxial tambo ndeyemukati uye yekunze maviri conductor, iyo yazvino kuburikidza nekondukita inoburitsa kuramba uye inductance, uye conductance uye capacitance pakati pemakondakita ichagadzirwa, uye yakagovaniswa pamwe nemutsara, inozivikanwawo se. kopi yakagoverwa.

Nekuda kweizvozvo, iyo chaiyo hunhu impedance yeiyo coaxial tambo ichave yakakwirira kupfuura iyo theoretical kukosha kana uchibatanidza iyo yekuratidzira system.Naizvozvo, kuti udzivise chiratidzo chekugona kuratidza chinogadzirwa nemamiriro ezvinhu aya uye kuve nechokwadi chekufambisa kwakanakisa, iyo terminal mutoro impedance inodiwa kuti ienderane netambo hunhu impedance zvakanyanya sezvinobvira.

 6.Attenuation maitiro: The attenuation maitiro ecoaxial tamboanowanzo zivikanwa neattenuation yenguva dzose, iyo yakaenzana ne decibels yechiratidzo chekuderedzwa kweiyo ikozvino pahurefu hweyuniti.Iyo attenuation yenguva dzose yeiyo coaxial tambo yakaenzana neiyo yekushanda frequency yechiratidzo, ndiko kuti, iyo yakakwira frequency inogadzirwa, iyo yakakura iyo attenuation inogara, yakadzikira frequency, idiki iyo attenuation inogara.

 Zvinofanira kucherechedzwa kuti mhando uye tsanangudzo dzecoaxial cablessiyana zvichienderana neyakasiyana application mamiriro uye zvinodiwa.Paunenge uchisarudza coaxial tambo, zvinodikanwa kuti utarise kuwanda kweiyo inofambiswa chiratidzo, kureba kwekufambisa, nharaunda yekushandisa, iyo interface mhando uye zvimwe zvinhu, kuitira kuti usarudze iyo yakakodzera modhi uye yakatarwa.
