Ua ntej tshaj plaws, cov kab hluav taws xob hluav taws xob yog cov kab ke tshwj xeeb rau kev xa hluav taws xob hluav taws xob, uas xa hluav taws xob hluav taws xob los ntawm ib qho chaw mus rau lwm qhov los ntawm cov hlau hlau. Txawm hais tias cov kab hluav taws xob tseem tuaj yeem xa hluav taws xob hluav taws xob, lawv xav tau ntau qhov chaw thiab, nyob hauv nroog lossis thaj chaw muaj neeg coob, lawv cov kev siv yuav cuam tshuam rau hauv nroog toj roob hauv pes thiab tib neeg lub neej txhua hnub. Hauv qhov sib piv, cov kab hluav taws xob tuaj yeem muab tso rau hauv av lossis hauv cov kav dej, uas tsis nyob hauv av thiab tsis cuam tshuam rau kev zoo nkauj ntawm lub nroog thiab tib neeg lub neej txhua hnub.
Qhov thib ob, cables tuaj yeem zam kev cuam tshuam nrog cov kab sib txuas lus. Thaum lub sij hawm xa hluav taws xob, electromagnetic teb raug tsim, uas yuav ua rau muaj kev cuam tshuam nrog cov kab sib txuas lus thiab cuam tshuam rau kev sib txuas lus zoo. Kev siv cov kab hluav taws xob tuaj yeem txo qhov cuam tshuam zoo, vim tias cov kab hluav taws xob feem ntau siv cov txheej thaiv thaiv los tiv thaiv cov teebmeem ntawm electromagnetic teb.
Tsis tas li ntawd, nws tseem yuav tsum tau siv cov cables hauv qee qhov chaw tshwj xeeb xws li txuas hniav, tunnels, subways, thiab lwm yam. Nyob rau hauv cov chaw no, qhov chaw muaj tsawg heev, thiab cov cables tuaj yeem nteg vertically lossis horizontally kom dhau los ntawm cov chaw no.
Hauv cov ntsiab lus, kev siv hluav taws xob cables tuaj yeem daws teeb meem zoo xws li kev ua haujlwm hauv chaw thiab kev sib txuas lus cuam tshuam, thiab txhim kho kev ntseeg siab thiab kev nyab xeeb ntawm kev xa hluav taws xob. Nyob rau tib lub sijhawm, lub zog hluav taws xob kuj tseem tuaj yeem yooj yim dhau los ntawm ntau qhov chaw tshwj xeeb, ua rau kev sib kis ntawm hluav taws xob hluav taws xob hloov tau yooj yim thiab yooj yim. Yog li ntawd, nyob rau hauv ntau zaus, kev siv fais fab cables yog qhov kev xaiv zoo tshaj plaws.
