Cov khoom siv sab hauv ntawm coaxial cables muaj ntau haiv neeg, feem ntau suav nrog tooj liab -clad steel, silver plated tooj liab, tin plated tooj liab, thiab lwm yam. Niaj hnub no, peb yuav qhia cov yam ntxwv thiab qhov zoo ntawm peb cov khoom siv feem ntau.
1, Copper clad steel
Copper clad steel hlau yog cov hlau sib xyaw nrog cov hlau hlau ua cov tub ntxhais thiab ib txheej ntawm tooj liab npog nws qhov chaw. Copper clad steel hlau sib txuas cov cuab yeej cuab tam ntawm lub zog siab thiab siab - kub softening tsis kam ntawm steel nrog cov khoom hluav taws xob ntawm cov khoom siv hluav taws xob siab thiab tsis tshua muaj kev sib cuag ntawm tooj liab. Yog li ntawd, nws muaj cov yam ntxwv ntawm high conductivity, tsis tshua muaj nqi khoom, siab tensile zog, lub teeb yuag, thiab hnav tsis kam. Nws tuaj yeem hloov cov khoom siv tooj liab hauv kev lag luam cable raws li cov neeg siv hluav taws xob rau cov khoom siv hluav taws xob ntau thiab tsawg zaus hauv kev lag luam kev sib txuas lus. Copper clad steel hlau ua ke nrog lub zog siab ntawm cov hlau nrog lub siab conductivity thiab corrosion kuj ntawm tooj liab, ua rau nws yog ib qho zoo tshaj plaws hlau nyob rau hauv kev sib txuas lus, lub hwj chim, thiab electronics industries. Lub thicker txheej tooj liab qhwv nyob ib ncig ntawm cov hlau nto, qhov siab dua DC conductivity.
Copper clad steel hlau yuav muab faib ua peb hom raws li conductivity: 21% IACS, 30% IACS, thiab 40% IACS (IACS thoob ntiaj teb annealed tooj liab qauv conductivity). Copper clad steel hlau tuaj yeem muab faib ua lub xeev mos (A), lub xeev nyuaj (HS), thiab lub xeev superhard (EHS) raws li nws cov khoom siv kho tshuab (lub xeev annealed). Feem ntau, RF cables siv cov tooj liab mos-clad steel nrog 30% lossis 40% IACS ua tus neeg xyuas pib.
2, Silver plated tooj liab
Nyiaj plated tooj liab hlau yog tsim los ntawm concentric plating ntawm ib txheej nyiaj ntawm ib tug tooj liab core. Nws muab cov yam ntxwv ntawm ob lub hlau, muaj qhov zoo conductivity, ci ntsa iab thiab glossy nto, thiab cov nyiaj txheej muaj kev tiv thaiv corrosion siab. Vim cov txiaj ntsig zoo no, nyiaj plated tooj liab hlau tau dhau los ua qhov kev xaiv zoo tshaj plaws rau siab - cov xov hlau zaus.
Nyiaj plated tooj liab hlau yog muab faib ua nyiaj plated mos puag ncig tooj liab hlau thiab nyiaj plated nyuaj round tooj liab hlau. Silver plated soft round tooj liab hlau yog annealed los hloov nws lub cev lub zog thiaj li ua tau softening. Ib tug zoo nyiaj plated tooj liab hlau txheej yog tsis tu ncua thiab nrees txuas rau saum npoo ntawm tus neeg xyuas pib, thiab cov qauv nto tseem dub tom qab kuaj. Qhov saum npoo ntawm cov nyiaj plated txheej yuav tsum yog du thiab tsis tu ncua, tsis muaj teeb meem tsis xws luag xws li nyiaj, burrs, mechanical puas, thiab lwm yam.
Nws cov yam ntxwv ua tau zoo suav nrog kev ua haujlwm siab thiab siab - tus yam ntxwv zaus. Tam sim no, feem ntau cov cables uas xav tau kev ua haujlwm siab siv cov nyiaj plated tooj liab ua cov khoom siv sab hauv, xws li SUJ series rau cov cables uas tsis tshua muaj thiab KBA series rau kev kuaj cables. Cov ntawv thov scenarios feem ntau yog nyob rau hauv aerospace thiab tub rog kev lag luam. Kev kub siab ua haujlwm, kev ua haujlwm kub ntawm -60℃~ +250 degree, thiab corrosion kuj.
3, tinned tooj
Tin plated tooj liab yog hais txog ib txheej nyias ntawm cov hlau tin plated rau saum npoo ntawm tooj liab, vim tias cov tin ua ib zaj duab xis nyias ntawm tin dioxide hauv huab cua, yog li tiv thaiv tooj liab los ntawm oxidized. Tin tuaj yeem tsim ib zaj duab xis nyias nrog halogens uas muaj cov nyhuv zoo sib xws. Yog li ntawd, nws muaj corrosion kuj zoo, tej lub zog thiab hardness, zoo formability thiab yooj yim welding, uas tsis yog - tshuaj lom thiab tsw ntxhiab tin txheej, thiab ib tug kaj nto.
Lub hom phiaj tseem ceeb ntawm tin plating tooj liab yog los tiv thaiv oxidation ntawm tooj liab. Nyob rau hauv lub cable series, tin plated tooj liab conductors kuj yog siv los ua puab conductors, tab sis lawv feem ntau xaiv raws li cov neeg xyuas pib (tin plated tooj liab hlau braided) zoo li semi saj zawg zog cables.
