Lub hwj chim cable yog ib hom cable siv rau kev sib kis thiab kev faib hluav taws xob; Nws yog tsim los ntawm tus neeg xyuas pib, txheej rwb thaiv tsev, txheej tiv thaiv, thiab txheej thaiv. Nws txoj haujlwm yog nyob ntawm kev xa cov hluav taws xob tam sim no los ntawm tus neeg xyuas pib, thaum txheej txheej rwb thaiv tsev ua kom muaj kev nyab xeeb ntawm hluav taws xob xa hluav taws xob los ntawm lub chaw nres tsheb fais fab mus rau qhov kawg - neeg siv.
Tus neeg xyuas pib:Tus neeg xyuas pib yog lub luag haujlwm rau kev sib kis; nws feem ntau yog ua los ntawm tooj liab lossis txhuas thiab muaj cov khoom siv hluav taws xob zoo heev. Cov neeg siv khoom tuaj nyob rau hauv ntau yam ntoo khaub lig-sectional shapes-xws li round, semi{3}}circular, thiab sector-shaped- kom haum rau ntau daim ntawv thov thiab cov kev xav tau.
Rwb thaiv tsev txheej:Lub rwb thaiv tsev txheej cais cov neeg xyuas pib los ntawm txheej tiv thaiv, tiv thaiv hluav taws xob. Nws feem ntau yog ua los ntawm cov ntaub ntawv xws li polyvinyl chloride (PVC) lossis ntoo khaub lig- txuas polyethylene (XLPE), uas muaj cov rwb thaiv tsev siab thiab dielectric zog. Cov txheej rwb thaiv tsev kom ntseeg tau tias tsis muaj qhov xau lossis luv luv -circuiting tshwm sim thaum lub cable ua haujlwm ntawm nws qhov ntsuas hluav taws xob.
Txheej tiv thaiv:Cov txheej tiv thaiv tiv thaiv txheej rwb thaiv tsev los ntawm kev puas tsuaj rau lub cev, xws li kev kub siab lossis kev puas tsuaj. Nws tuaj yeem tsim los ntawm cov khoom siv xws li PVC, polyethylene, lossis lwm yam.
Shielding Txheej:Cov ntaub thaiv npog feem ntau yog tooj liab lossis txhuas daim kab xev qhwv ib ncig ntawm lub cable; nws pab txo cov electromagnetic cuam tshuam thiab txhim khu lub cable tsis kam mus rau xws li cuam tshuam.
Hauv cov ntsiab lus, txoj hauv kev ua haujlwm ntawm lub hwj chim cable suav nrog qhov ntws ntawm cov khoom siv tam sim no, nrog cov txheej txheem rwb thaiv tsev kom muaj kev nyab xeeb ntawm lub zog, thaum cov txheej tiv thaiv thiab thaiv cov txheej txheem muab cov khoom siv dag zog thiab kev cuam tshuam tsis zoo. Qhov no ua rau lub hwj chim cable kom muaj kev nyab xeeb xa hluav taws xob hluav taws xob los ntawm qhov chaw nres tsheb fais fab mus rau ntau qhov chaw siv.
