Yaya za a iya gani ingancin RF coaxial cables

Matsar RF coaxial cables shine a kansu daya akan tsayar da kuskurewar kiran bayanai. RF coaxial cable mai yawa shine wanda ke da tsoho mai yawa, kuma tatta ya na gaba shine aluminum foil na cable ya yi karshen ƙarfe na al'ada. A karkashin, farashin al'ada shine gaba daya kuma aiki shine mai yawa. Yau, mai gyara zai taka mu fahimtar yadda za a sami matsar RF coaxial cables.

1) Duba tsohon al'ada

Tambin RF coaxial da keɓuwa ta fi girma da keɓuwa, ko da shi ne ƙarfe na gaba na keɓuwar da aluminum foil da ke ƙasa na gaba na insulating medium. Karfi na gaba na medium, ƙarƙarin gaban aluminum foil da karfi na gaba, kuma baƙi ne gaban idan ba girma ba. Kuma ya tabbata da hanyar aiki cewa ƙarƙarin gaba, mai kyau aiki na keɓuwar. A cikin saƙo, gabanin da ke girman gabanin yake ƙalƙali daga cikin ƙarfe na gabanin, ya dace yawan shekara da keɓuwar.

2. Duba tare da insulating medium na keɓuwar coaxial

Girman girman insulating medium na keɓuwar coaxial ta nufin cin gabanin coefficient na keɓuwar. Wannan duba zai iya cutar insulating medium na ƙasa na keɓuwar, kuma duba girman karfi na kowanne alamar ta amfani da micrometer don san idan tare ce ko bai.

3. Duba maita'a na aluminum foil

Aluminum foil ya ke tsarin gudun gudun a cikin kwayoyin coaxial, wanda ya iya kula da gudun fito na siginlura kuma ya iya kula da gudun siginlura na wasan TV. Don haka, aluminum foil dole ne a yi testinsa don kwayo barkwanci. Muna, cut open the protective layer kuma duba dalibanin kofa da sauran aluminum foil layer ta hanyar gudun shine; Bayan na, za a sami section na kwayo kuma a cicipa ta da fatan a metal shaft. Straighten kuma a yi twist a berfinsa, repeat several times, bayan na cut open cable sheath layer kuma duba in da ba a cire aluminum foil ba. Ko kuma za a iya cut small section na aluminum foil kuma a yi rub kuma a yi stretch a cikin hannun. Idan ya zai zunchi ba ne bayan cikin rub da stretch, shine wuyi wuye shine ya da certain degree na toughness. Idan ba haka ba, shine wuyi wuye ya da shawarwari.

4. Duba kwayo na coaxial cable braided mesh

Takadda na ƙofa na kwayoyin ko7asun siffar da ke da alaƙa da kwayoyin ko7asun siffar, kuma idan ake ciki ko bayanin karkashin da ke cikin abokan cin gida ko karkashin batiri, mutum ya zai buƙata duba jin takadda na ƙofa na kwayoyin ko7asu ya zai daidai ko kada ya zai daidai. Hanyar amsawa shine ta watsa gabaɗaya na kwayoyin ko7asu, ta cutar wani ƙasaƙan takadda na kwayoyin ko7asu, kuma ta gani adadin takadda. Idan ya zai daidai da abubuwan da aka bamuta, to ana amfani da shi. Sannan kuma, takadda ta biyu ta ke cikin ƙofa ana makkawa da micrometer. A karkashin daidai, karfi na takadda ya zai girma, girma ne kwalitun.

5. Duba tushen takadda na gabaɗaya

Takadda na amma na kwayoyin coaxial mai yawa shine ta hanyar taka, wanda zai iya kara tsawon cikin takadda ta gaskiya, kama da ruwa don kada su faru sabbin gudun, kuma kada su kirkira takadda don kada su faru tsinkin al'ada na karkatarwa. Ama idan takadda shine ta hanyar taka, zai zama ba tare da tasanne don gudun farko kuma zai kara matsalolin aikar. Hanyar tattauna shine za a sami kwayo mai yawan 1m kuma za a gudun takadda a farko, don haka za core zai zama ba za a iya gudun shi ba.

6, Dubi kwayo ta hanyar kirkira wurin guda

An formation na kwayoyi ba ta nuna da aka fuskantar su ne, amma duba kuma a kwaliti na kwayo. An formed kwayo a cikin gaba daya, kuma kwayo kowane ya yi a sama da concentric plane. Kwayo suna da fadin cikin busu daya da karkashin gaba daya, wanda zai tattara aikin da ke tsakanin kwayo kuma ya kara macewa ko kai tsoro lokacin da suka tsaya. Don haka, lokacin da kai duba kwaliti na kwayo, kada ka yi karfi ko inu duba, amma duba da kankara.
