High zaus thiab tsis tshua muaj kev sib txuas lus cables feem ntau yog ua los ntawm foamed polyethylene los yog foamed polypropylene li insulating cov ntaub ntawv, ob insulating core xov hlau thiab ib tug hauv av xaim (tam sim no lub khw kuj muaj manufacturers siv ob npaug rau hauv av) rau hauv lub tshuab winding, wrapping aluminium foil thiab roj hmab. polyester daim kab xev nyob ib ncig ntawm lub insulating core hlau thiab hauv av hlau, rwb thaiv tsev txheej txheem tsim thiab txheej txheem tswj, high-ceev kis kab qauv qauv, hluav taws xob kev ua tau zoo yuav tsum tau thiab kis txoj kev xav.
Conductor xav tau
Rau SAS, uas tseem yog cov kab sib kis tau zoo, cov qauv kev sib xws ntawm txhua qhov yog qhov tseem ceeb hauv kev txiav txim siab qhov sib kis ntawm cov cable.Yog li ntawd, raws li ib tug neeg xyuas pib ntawm high-frequency kis tau tus mob kab, qhov saum npoo yog puag ncig thiab du, thiab cov txheej txheem nyob rau hauv lub lattice yog uniform thiab ruaj khov los xyuas kom meej lub uniformity ntawm hluav taws xob khoom nyob rau hauv cov kev taw qhia ntawm ntev;Tus neeg xyuas pib kuj yuav tsum muaj DC tsis kam;Nyob rau tib lub sij hawm yuav tsum tsis txhob vim hlau, khoom siv los yog lwm yam khoom siv los ntawm lub internal conductor ncua sij hawm bending los yog non-periodic dabtsi yog khoov, deformation thiab puas, thiab lwm yam., nyob rau hauv lub high-frequency kis kab mob, conductor kuj yog lub ntsiab ua rau cable. attenuation (high-frequency parameters part 01- attenuation parameters), muaj ob txoj hauv kev los txo tus neeg xyuas pib: nce tus neeg xyuas pib txoj kab uas hla, xaiv cov khoom siv hluav taws xob tsawg.Tom qab tus neeg xyuas pib txoj kab uas hla nce ntxiv, txhawm rau ua kom tau raws li qhov yuav tsum tau muaj ntawm cov yam ntxwv impedance, cov kab hluav taws xob sab nraud ntawm cov rwb thaiv tsev thiab cov kab hluav taws xob sab nraud ntawm cov khoom tiav yog sib npaug, uas ua rau cov nqi nce thiab kev ua haujlwm tsis zoo.Nyob rau hauv txoj kev xav, siv nyiaj conductor, sab nraud txoj kab uas hla ntawm cov khoom tiav yuav raug txo, thiab kev ua tau zoo yuav zoo dua, tab sis vim hais tias tus nqi ntawm cov nyiaj ntau dua tus nqi ntawm cov tooj liab, tus nqi yog siab heev rau cov khoom loj, Yuav kom coj mus rau hauv tus account tus nqi thiab tsis tshua muaj resistivity, peb siv cov nyhuv ntawm daim tawv nqaij los tsim tus neeg xyuas pib ntawm cable.Tam sim no, kev siv cov tinned tooj liab conductors rau SAS 6G tuaj yeem ua tau raws li kev ua haujlwm ntawm hluav taws xob, thaum SAS 12G thiab 24G tau pib siv nyiaj-plated conductors.
Thaum muaj alternating tam sim no los yog alternating electromagnetic teb nyob rau hauv tus neeg xyuas pib, tam sim no tis nyob rau hauv tus neeg xyuas pib yuav tsis sib xws.Raws li qhov kev ncua deb ntawm tus neeg xyuas pib maj mam nce, qhov ceev tam sim no hauv tus neeg xyuas pib txo qis, uas yog, tam sim no nyob rau hauv tus neeg xyuas pib yuav mloog zoo rau ntawm tus neeg xyuas pib.Los ntawm lub dav hlau transverse perpendicular mus rau cov kev taw qhia ntawm tam sim no, tam sim no siv ntawm lub hauv paus ntawm tus neeg xyuas pib yog xoom, uas yog, yuav luag tsis muaj tam sim no ntws, thiab tsuas yog ib feem ntawm ntug ntawm tus neeg xyuas pib yuav muaj subcurrents.Cias muab, tam sim no yog concentrated nyob rau hauv "tawv nqaij" ib feem ntawm tus neeg xyuas pib, yog li nws yog hu ua cov nyhuv ntawm daim tawv nqaij.Yog vim li cas rau qhov tshwm sim yog tias qhov hloov hluav taws xob ua hluav taws xob tsim hluav taws xob vortex hauv cov neeg xyuas pib, uas yog offset los ntawm qhov qub tam sim no.Cov nyhuv ntawm daim tawv nqaij ua rau tus neeg xyuas pib qhov kev tiv thaiv nce ntxiv nrog qhov nce ntawm qhov zaus ntawm kev hloov pauv tam sim no, thiab ua rau txo qis kev ua haujlwm ntawm cov xaim xaim tam sim no, siv cov khoom siv hlau, tab sis nyob rau hauv kev tsim ntawm high-frequency kev sib txuas lus cables, lub hauv paus ntsiab lus no tuaj yeem ua tau. siv los txo cov hlau siv los ntawm kev siv nyiaj plating rau saum npoo raws li qhov ua tau raws li qhov yuav tsum tau ua, yog li txo cov nqi.
Rwb thaiv tsev xav tau
Ib yam li tus neeg xyuas pib xav tau, qhov nruab nrab insulating yuav tsum zoo ib yam, thiab txhawm rau kom tau txais qhov qis dua dielectric tas li s thiab dielectric poob lub kaum sab xis tus nqi, SAS cables feem ntau siv ua npuas ncauj rwb thaiv tsev.Thaum lub foaming degree ntau dua 45%, tshuaj foaming nyuaj ua tiav, thiab cov degree foaming tsis ruaj khov, yog li cov cable saum toj no 12G yuav tsum siv lub cev foaming rwb thaiv tsev.Raws li pom nyob rau hauv daim duab hauv qab no, thaum lub foaming degree siab tshaj 45%, seem ntawm lub cev foaming thiab tshuaj foaming pom nyob rau hauv lub microscope, lub cev foaming pores yog ntau thiab me, thaum cov tshuaj foaming pores yog tsawg thiab loj:
