Daim ntawv thov ntawmsilica hauv cable
Lub hauv paus tseem ceeb txiav txim siab nrog lub zog ntawm cov hluav taws xob hluav taws xob muaj raws li hauv qab no:
A. Qhov ntsuas kub siab tshaj plaws ntawm insulating media lossis lwm yam khoom siv cable.
B. Kev ua kom zoo thaum tshav kub kub ntawm cov xaim hluav taws xob thiab hluav taws xob tawm.
C. Kev ceev ntawm kev coj ntawm (lossis cable loj).
D. Dielectric tas mus li thiab dielectric poob qhov ntawm dielectric.E. Cov xwm txheej tshwj xeeb xws li thaj chaw ua haujlwm
Kev soj ntsuam yooj yim, yog tias qhov chaw ua haujlwm, xws li ntsuas kub, qhov siab ua haujlwm thiab kev ua haujlwm nquag tau tsau, yog tias yuav tsum tau nce lub zog ntawm lub zog, nws yuav tsum: 1. nce qhov ntsuas kub ntawm cable rwb thaiv tsev nruab nrab, 2. Txo tsawg cua sov ( txo cable poob), 3. So tawm thaum tshav kub kub sai li sai tau (txo qhov sib npaug ntawm qhov kub thiab txias),.
Ntawm peb txoj hauv kev hais saum toj no, qhov ncaj qha tshaj plaws yog nce qhov kub ntawm qhov nruab nrab insulating, thiab qhov thib ob yog txo qhov poob. Txoj hauv kev zoo tshaj plaws los txo qhov poob yog txhawm rau txhawm rau txoj kab uas hla ntawm lub cable, thiab qhov thib ob yog siv cov kab hluav taws xob nruab nrab nrog qhov qis dielectric tas li. Txawm li cas los xij, nws tsis yooj yim los txhim kho cov thermal conductivity vim yog cov khoom siv vim li cas, yog li tam sim no kev tsom xam tam sim no yog rau thawj thiab thib ob ob lub ntsiab lus. Tib lub sijhawm, nyob rau ntau qhov xwm txheej, vim tias qhov loj me ntawm lub cable yog qhov txwv tau zoo, lossis rau kev sib piv yooj yim, cov cable nrog tib lub dav dav feem ntau siv los piv cov siab tshaj plaws hwj chim.
Txoj kev no, nws tsuas muaj ob txoj hauv kev. Ib qho yog los txhim kho qhov kub thiab txias tsis txaus rau lub cable rwb thaiv tsev nruab nrab, thiab lwm qhov yog xaiv cov rwb thaiv tsev nruab nrab nrog qis dielectric tas li.
Hauv qab no yog qhov ntsuas kub thiab dielectric tas li ntawm cov ntaub ntawv insulating:
Lub npe ntawm Insulating Cov Khoom Kub Lub Cev Muaj Peev Xwm Qib Qib (C) Dielectric Tas Nrho
Polyethylene (PE) 80-100 2.35
Foamed polyethylene (FPE) 80-100 1.26-1.65
Polypropylene (PP) 150 2.2-2.4
Polytetrafluoroethylene (PTFE) 260 2.0-2.1
Foamed polytetrafluoroethylene (EPTFE) 260 1.38-1.65
Silica (SIO 2) 1723 1.58
Los ntawm cov ntsuas saum toj no, peb tuaj yeem pom tias silicon dioxide cable muaj qhov zoo nyob rau hauv kev txhim kho lub zog tiv thaiv.
(2) Qhov siab tshaj plaws ntawm qhov fais fab sib piv ntawm cov hluav taws xob tiag
Cov lus hauv qab no qhia txog qhov siab tshaj plaws nrog lub zog sib piv ntawm cov kab hluav taws xob uas yuav luag sib npaug nrog cov sib txawv insulating cov ntaub ntawv (qib hiav txwv, 20 C):
Lub npe ntawm insulating cov khoom siv, kev paub meej cable, qhov siab tshaj plaws nrog lub zog (CW @ 10GHz), muaj peev xwm tiv thaiv ntau tshaj plaws (CW@0.4GHz)
Polyethylene (PE) RG223 N / A 86
Foamed Polyethylene (FPE) LM195 N / A 250
Polytetrafluoroethylene (PTFE) UT-141C 117.5 660
Cov Khoom Siv Polytetrafluoroethylene Ua Ntej (EPTFE)UFB-142A 172 N / A
Silica (SIO 2) S142 1450 N / A
