Kableeynta Coaxial Dheerka Raadiodka RF

Kabalka coaxial waxay leeyihiin qaybo daro, oo kastoo ka caawiya in uu siinayo isku darka sare ee ammaanka hoose. Qaybta u dhaxaysa ayaa lagu guda garaynaa, waxaana badan ah copper (midabka ama jiljilka) ama copper oo daba joogay steel. Copper waxaa loogu talagalay sababta in ay leeyihiin waxa ka siinaya ammaan gaar ah, oo khabar dadka siinista ammaan, haddana copper oo daba joogay steel waxay siinaya isku midka waxa ka siinaya ammaan iyo xoog, kaas oo kala badaya qiimo. Kabaxa u dhaxaysa ayaa lagu guda dielectric insulator, kaas oo leeyahay u dhowiyo la xirgalo bidaalka iyo qaybta u jeedka ee shieldiga, si loo kala saaro ammaan laabida. Qaabka dielectric waxay leeyihiin polyethylene (midabka ama foam), polypropylene, ama Teflon; polyethylene foam waa qaab ugu sarreeya kabalka sare ee ammaan (sida 5G feeders) sababta in ay leeyihiin dielectric constant hoose, kaas oo kala badaya ammaan laabida. Qaybta soo socda ayaa shieldiga, kaas oo awooda in la joojiyo electromagnetic interference (EMI) ee la soo gelay bidaalka iyo in la kala saaro ammaanka kabalka in la joojiyo qalabka kale. Shieldigaa waxaa jiraa qaybta aluminum foil, meshka braided ee copper ama aluminum, ama isku dar ama ka mid ah laba tiro - multi layer shielding, sida kabalka Hebei Mailing oo durba, waxay siinaya in EMI awooda si joogto ah. Qaybta ugu dambaysa ayaa lagu guda jacket (ama sheath), oo loo sameeyay PVC, polyethylene, ama rubber, kaas oo awooda in la aarsado qaybta dhexe ee laabka, naxaas, iyo xagga jirka. Tusaale ahaan, kabalka PVC (oo loo isticmaala Hebei Mailing KC97 iyo KC80) waxay leeyihiin waxa ka siinaya ammaan iyo xoogga dhiciyada, kaas oo khabar dadka isticmaalka ganacsiga iyo ganacsiga. Isku dhow, qaabkaas oo kala duwan waxay siinaya in kabalka siinista, durba, iyo awooda si joogto ah ee jirka jirka.
