Nyob rau hauv hluav taws xob engineering thiab kev siv hlau,Nm {- b hlau (tsis - nws yog xim hlau sheathed cable, hom b)Puas yog ib qho kev xaiv muaj feem ntau rau cov chaw nyob thiab lub teeb lag luam lag luam hauv Tebchaws Meskas. Thaum xaiv cov xov hlau, ntau cov neeg cog lus, hluav taws xob, thiab cov neeg yuav khoom feem ntau ntsib cov lus nug tseem ceeb:
"Puas yog nm {- b hlau tawm lossis ruaj khov?"
Lo lus nug no yog qhov tseem ceeb vim tias tus qauv coj cwj pwm (khoom vs. stranded) cuam tshuam ncaj qha:
- Kev Ua Hluav Taws Xob Hluav Taws Xob(Tam sim no {- nqa muaj peev xwm, kev tawm tsam, impedance);
- Teeb kev yooj yim(Dabtsi yog khoov, conduit tau rub, kev sib tham);
- Daim Ntawv Thov Kev Pab Cuam(Txhim kho wiring thiab siv tau).
Dab tsi yog cov hlau thiab cov hlau pov cov hlau?
- Khoom Hlau: Ua los ntawm ib qho, txuas ntxiv tooj liab tus neeg xyuas.
- Hlau Nplaum: Muaj ntau ntawm ntau cov tooj liab me me ntawm cov kab sib ntswg sib xyaw ua ke los ua ib tus neeg xyuas.
Qhov sib txawv ntawm cov khoom thiab cov hlau pov tseg
