Litšobotsi tsa cable ea coaxial

Coaxial cableke mofuta oa thapo e inehetseng ho phetiso ea data le mats'oao, e nang le mochini o kenang bohareng, lera la insulation, lera la thebe ea letlooeng, lesela le ka ntle la insulation le lesela la sheath.Mokhanni o bohareng oa thapo ea coaxial ke terata ea tšepe, hangata e entsoeng ka koporo kapa aluminium, lesela le sireletsang hangata le entsoe ka polypropylene kapa polyethylene, 'me lesela le sirelelitsoeng la mesh le koahetsoe ke lesela la insulating' me le entsoe ka terata ea koporo kapa foil ea aluminium. .Coaxial cablee sebelisoa haholo marang-rang a likhomphutha, phetiso ea lets'oao la TV, lits'ebetso tsa ts'ireletso, liteishene tsa seea-le-moea le mafapha a mang.

Tse latelang ke tse ling tsa likarolo tse ka sehloohong tsathapo ya coaxial:

 1. Tšitiso ea anti-electromagnetic: Lera le sireletsang ka hare la mesh ea coaxial cable le ka khona ho hanela tšitiso ea ka ntle ea motlakase le ho netefatsa botsitso le ho tšepahala ha phetisetso ea matšoao.

 2. Matla a maholo: Mokhanni oa bohareng oathapo ya coaxialke terata ea tšepe, conductivity e ntle, bokhoni bo boholo, e ka fetisa lipontšo tse phahameng tsa maqhubu.

 3. Sebaka se selelele sa phetisetso ea mats'oao: sebaka sa phetiso ea mats'oao a thapo ea coaxial e hole ho feta ea thapo e akaretsang, 'me sebaka sa phetiso hangata se tloha ho lik'hilomithara tse' maloa ho isa ho tse mashome a lik'hilomithara.

 4.Tšireletso ea Sheath layer: Coaxial cable outer insulation layer le sheath layer e ka sireletsa sebopeho sa setsi sa cable ka katleho le ho lelefatsa bophelo ba ts'ebeletso ea thapo.

 5.Impedans ea sebopeho: karolo ea mantlha ea thapo ea coaxial ke li-conductor tse peli tse ka hare le tse ka ntle, hona joale ka mokhanni o tla hlahisa khanyetso le inductance, 'me conductance le capacitance lipakeng tsa li-coaxial li tla hlahisoa,' me li abuoe moleng, o tsejoang hape e le. kopi e ajoang.

Ka lebaka leo, ts'ebetso ea 'nete ea ts'ebetso ea thapo ea coaxial e tla ba e phahameng ho feta boleng ba theory ha o hokahanya sistimi ea ponts'o.Ka hona, molemong oa ho qoba ponts'o ea bokhoni ba lets'oao le hlahisoang ke boemo bona le ho netefatsa phello e ntle ka ho fetisisa ea phetisetso, phepelo ea phetiso ea terminal e hlokahala hore e tsamaellane le "cable character impedance" ka hohle kamoo ho ka khonehang.

 6.Attenuation characters: Litšobotsi tsa phokotso eathapo ya coaxialka kakaretso li khetholloa ke attenuation constant, e leng ho lekanang le di-decibel tsa phokotso ya matshwao a jwale ka bolelele ba yuniti.The attenuation constant of the coaxial cable is propobility to operation frequency of the signal, that is, the high frequency generated, the attenuation constant constant, the lower frequency, the smaller the attenuation constant.

 Ho lokela ho hlokomeloa hore mefuta le litlhaloso tsalikhoele tsa coaxialfapana ho ea ka maemo a fapaneng a ts'ebeliso le litlhoko tse fapaneng.Ha u khetha thapo ea coaxial, hoa hlokahala ho nahana ka makhetlo a lets'oao le fetisoang, sebaka sa phetisetso, tikoloho ea ts'ebeliso, mofuta oa sebopeho le lintlha tse ling, e le ho khetha mohlala o nepahetseng le litlhaloso.
