Kev Tshawb Fawb Tom Qab Cov Khoom Siv rau Cov Khoom Siv Hluav Taws Xob
Cables yog ib feem tseem ceeb ntawm kev sib txuas lus niaj hnub no vim lawv muaj lub luag haujlwm rau kev xa cov ntaub ntawv qhia txog qhov ntev. Txawm li cas los xij, tsis yog txhua lub cables raug tsim sib npaug.
Tus coj
Qhov tseem ceeb tshaj plaws ntawm lub cable yog nws tus neeg xyuas pib, uas yog lub luag haujlwm rau kev xa hluav taws xob cov teeb liab. Cov kab hluav taws xob zoo siv tooj liab lossis txhuas ua tus neeg xyuas pib vim tias lawv muaj qhov tsis zoo thiab yog cov khoom siv hluav taws xob zoo heev. Txawm li cas los xij, cov tooj liab ntshiab lossis txhuas cov khoom siv yog mos heev rau kev siv tswv yim, yog li lawv feem ntau ntxiv nrog lwm cov ntaub ntawv los ua kom lawv lub zog.
Rwb thaiv tsev
Rwb thaiv tsev yog lwm qhov tseem ceeb ntawm cov kab hluav taws xob zoo. Nws yog lub luag haujlwm los tiv thaiv cov teeb liab poob, cuam tshuam electromagnetic, thiab hloov thermal. Muaj ntau cov ntaub ntawv muaj rau rwb thaiv tsev, tab sis cov ntaub ntawv siv feem ntau yog polyvinyl chloride (PVC), polyethylene (PE), thiab polypropylene (PP). PVC yog qhov feem ntau siv vim nws hloov tau, pheej yig, thiab muaj cov khoom siv rwb thaiv tsev zoo heev. Txawm li cas los xij, nws tsis haum rau qhov chaw kub kub thiab tuaj yeem tawm cov pa phem thaum overheated.
Tiv thaiv
Shielding yog ib txheej txheej ntxiv uas nyob ib puag ncig tus neeg xyuas pib thiab cov insulator los tiv thaiv cov cable los ntawm kev cuam tshuam sab nraud, xws li electromagnetic teb los ntawm ib puag ncig ib puag ncig. Cov ntaub thaiv npog tuaj yeem ua los ntawm ntau yam ntaub ntawv, xws li tooj liab braid, aluminium ntawv ci, los yog tooj liab daim kab xev. Copper braid yog nyiam vim nws hloov tau thiab tuaj yeem khoov ntawm cov ces kaum yam tsis muaj kev tawg.
Jacketing
Cov txheej txheej sab nraud ntawm lub cable yog lub tsho, uas tiv thaiv lub cable los ntawm kev puas tsuaj rau lub cev, noo noo, thiab ib puag ncig yam. Muaj ntau ntau yam khoom siv rau lub tsho, xws li PVC, polyurethane (PU), thiab thermoplastic elastomer (TPE). PVC yog cov khoom siv ntau tshaj plaws vim nws hloov tau, pheej yig, thiab ruaj khov. Txawm li cas los xij, PU thiab TPE yog qhov zoo dua rau qhov chaw hnyav vim tias lawv muaj peev xwm tiv taus tshuaj lom neeg thiab UV teeb.
Xaus
Kev xaiv cov ntaub ntawv zoo yog qhov tseem ceeb rau kev tsim cov kab hluav taws xob zoo uas tuaj yeem xa cov teeb liab tau zoo nyob rau qhov ntev. Tooj lossis txhuas yog cov ntaub ntawv zoo tshaj plaws rau cov neeg xyuas pib, thiab PVC yog cov khoom siv rau kev rwb thaiv tsev vim nws qhov yooj yim thiab zoo heev rwb thaiv tsev. Kev tiv thaiv tuaj yeem ua los ntawm tooj liab braid, thiab lub tsho tuaj yeem ua los ntawm PVC, PU, lossis TPE, nyob ntawm ib puag ncig uas siv lub cable.
