Nyob ntawm cov khoom siv ntawm lub network cable, tus nqi kuj sib txawv.
1. Copper-clad steel network cable: tsis kam ntawm 100 meters yog li 75-100 ohms.Qhov no cable kuj yog qhov pheej yig tshaj cable ntawm kev ua lag luam, thiab cov nyhuv ntawm kev sib txuas lus tsis zoo heev.
2. Copper-clad aluminium network cable: qhov tsis kam ntawm 100 meters yog li 24-28ohms.Hom kab hluav taws xob network no zoo dua muag hauv khw, kuj pheej yig, thiab kev sib txuas lus thiab cov txiaj ntsig zoo.Tab sis kev pab cuam lub neej tsis zoo, vim tsis muaj oxidation tsis kam.
3. Copper-clad silver network cable: tooj liab-clad silver kuj hu ua high conducting aluminium network cable.Cov khoom siv yog purer dua li tooj liab-clad aluminium, thiab qhov tsis kam yog li 100 meters thiab 15ohms.Qhov kev sib txuas lus deb yog ntev tshaj li tooj liab-clad aluminium network cable.Tab sis nws cov shortcomings yog tib yam li tooj liab clad aluminium network cable, lub neej yog tsis ntev, tsis zoo oxidation kuj.
4. Copper-clad tooj liab network cable, qhov kev tiv thaiv ntawm lub network cable tsis yog me me, 100 meters kuj tus nqi yog hais txog 42 ohms, kev ua tau zoo yog feem ntau zoo, tab sis nws muaj zog oxidation tsis kam, kev pab cuam lub neej ntev npaum li cas tooj liab clad txhuas.
5. Oxygen-free copper network cable: oxygen-free copper network cable yog qhov tsawg kawg nkaus tsis kam, 100 meters kuj yog hais txog 9.5 ohms, cov hlau no yog qhov kev ua tau zoo tshaj plaws ntawm kev ua lag luam.
