Cov kab hluav taws xob tswj feem ntau yog siv rau kev xa cov teeb liab tswj thiab feem ntau pom muaj nyob rau hauv cov ntawv thov xws li kev lag luam automation, cov cuab yeej siv tshuab, thiab lub tsev automation systems. Lawv lub luag haujlwm tseem ceeb yog xa cov lus txib es tsis yog siab - lub zog hluav taws xob lossis siab - cov ntaub ntawv ceev. Feem ntau, cov kab hluav taws xob tswj tau muaj ntau yam insulated cores encased nyob rau hauv ib txheej txheej; nws cov qauv tsim muaj qhov tseem ceeb ntawm qhov yooj yim thiab ua haujlwm rau electromagnetic cuam tshuam.
Cov conductors feem ntau yog ua los ntawm tooj liab lossis txhuas, nrog rau tooj liab yog qhov kev xaiv ntau dua vim nws cov conductivity superior thiab oxidation tsis kam. Ntau yam ntaub ntawv insulating-xws li polyethylene (PE) thiab polyvinyl chloride (PVC)- raug xaiv raws li cov kev cai tshwj xeeb ntawm qhov chaw ua haujlwm. Lub shielding txheej yog ib qho tseem ceeb ntawm kev tswj cov cables; nws tuaj yeem siv rau hauv daim ntawv ntawm braided tooj liab hlau los yog txhuas-cov ntaub ntawv yas sib xyaw, ua haujlwm kom txo tau cov kev cuam tshuam sab nraud electromagnetic. Lub sab nrauv muab kev tiv thaiv txhua yam thiab huab cua tiv thaiv; Cov ntaub ntawv xws li PVC, PE, lossis tsawg- pa luam yeeb, xoom-halogen (LSZH) cov khoom siv los ua kom haum rau sab hauv tsev, sab nraum zoov, lossis tshwj xeeb ib puag ncig.
Cov kab hluav taws xob tswj feem ntau muaj qhov ntsuas qis qis, feem ntau poob hauv 300-volt lossis 500-volt chav kawm. Tus naj npawb ntawm cov cores yog nyob ntawm ob peb mus rau ntau lub kaum os, thiab xim-coding yog ua haujlwm los pab txhim kho thiab kho. Thaum xaiv ib lub cable tswj, yam xws li kev khiav hauj lwm ib puag ncig, zaus ntawm kev txav, thiab khoov vojvoog yuav tsum tau muab rau hauv kev txiav txim siab; Piv txwv li, cables npaj rau siv nyob rau hauv cable cab chains yuav tsum tau exceptional yooj.
