ntawm hluav taws xob uas nres qhov ntws ntawm hluav taws xob los ntawm nws.
Vim li cas cov xov hlau qhwv hauv roj hmab?
Feem ntau cov xaim hluav taws xob tau them rau hauv cov roj hmab lossis yas txheej hu ua rwb thaiv tsev. … Lub hom phiaj ntawm rwb thaiv tsev npog cov hlau ntawm cov hlau hluav taws xob yog txhawm rau tiv thaiv kev sib cuag nrog lwm cov hluav taws xob hluav taws xob, uas yuav ua rau muaj hluav taws xob tsis zoo los ntawm lwm tus neeg xyuas.
tooj liab yog dab tsi?
cov xov tooj tooj liab feem ntau yog them nrog roj hmab lossis yas txhawm rau tiv thaiv kev poob siab thiab ua kom muaj kev nyab xeeb. Vim tias cov yas thiab roj hmab yog cov rwb thaiv tsev hluav taws xob xws li lawv tsis tuaj yeem ua hluav taws xob.
Puas yog tooj liab hlau ntshiab tooj liab?
Khoom tooj liab conductors txhais tau hais tias cov cables nyob ntawm qhov ntevkhoom hlau es tsis txhob ntau tooj liab strands ua ib tug hlau zoo li stranded cable. … Qhov no txhais tau hais tias lub cable muaj cov khoom conductors uas yog ua los ntawm tooj liab clad aluminium es tsis txhob ntawm cov tooj liab ntshiab.
Vim li cas tooj liab siv?
tooj liab hluav taws xob xaim muaj kev nyab xeeb dua li cov xov hlau ua los ntawm lwm cov hlau conductive vim lawv tiv taus cua sov. Raws li koj tuaj yeem pom, tooj liab yog cov hlau nyiam rau cov xov hlau hluav taws xob rau ntau qhov laj thawj. Nws muaj hluav taws xob conductive; nws pheej yig; nws yog ductile; thiab nws yog thermal resistant.
