Ehia mau ohms ka waiwai kū'ē o ka wae 5E (cat 5e) uwea?

Ma muli o ka mea o ke kaula pūnaewele, heʻokoʻa ka waiwai kū'ē.

1. Copper-clad steel network cable: kū'ē o 100 mika ma kahi o 75-100 ohms. ʻO kēia kelepona ʻo ia hoʻi ke kelepona ʻoi loa ma ka mākeke, a ʻaʻole maikaʻi loa ka hopena o ke kamaʻilio.copper clad steel 2

 

 

 

 

2. ʻO ke kaula alumini alumini i hoʻopaʻa ʻia i ke keleawe: ʻo ke kūpaʻa o 100 mika ma kahi o 24-28ohms. ʻOi aku ka maikaʻi o ke kūʻai ʻia ʻana o kēia ʻano kelepona pūnaewele ma ka mākeke, maʻalahi, a maikaʻi ka mamao o ke kamaʻilio ʻana a me ka hopena. Akā ʻaʻole maikaʻi ke ola lawelawe, no ka maikaʻi ʻole o ka pale ʻana i ka oxidation.

3. Kāhea ʻia ke kala keleawe i ʻaʻahu ʻia i ke keleawe: ua kapa ʻia ke kelepona alumini hoʻokele kiʻekiʻe. ʻOi aku ka maʻemaʻe o ka mea ma mua o ka alumini keleawe, a ʻo ke kū'ē ʻana ma kahi o 100 mika a me 15ohms. ʻOi aku ka lōʻihi o ke kamaʻilio ʻana ma mua o ke uwea pūnaewele alumini ʻaʻahu keleawe. Akā ʻo kona mau hemahema, ua like ia me ke kaula keleawe a ʻaʻahu alumini, ʻo ke ola inā ʻaʻole lōʻihi, maikaʻi ʻole ke kūpaʻa oxidation.

4. Copper-clad copper network cable, ʻaʻole liʻiliʻi ke kūʻē o kēia uea pūnaewele, ʻo 100 mika ke kūʻai aku ʻana ma kahi o 42 ohms, ʻoi aku ka maikaʻi o ka hana, akā ikaika ke kūpaʻa oxidation, ʻoi aku ka lōʻihi o ke ola lawelawe ma mua o ke alumini keleawe.

 

5. Oxygen-free copper network cable: oxygen-free copper network cable ka palena haʻahaʻa loa, 100 mika ke kū'ēʻana ma kahi o 9.5 ohms,ʻo kēia uea ka hana maikaʻi loa ma ka mākeke.
