隨著大(da)數(shu)據時代的到來，信(xin)息交互量(liang)越(yue)來越(yue)大(da)。作為安(an)防(fang)通信(xin)、網(wang)絡通信(xin)及(ji)相關弱電傳輸(shu)用途的弱電電纜在國(guo)內乃至全(quan)球都有巨大(da)的應用市(shi)場。

有關調(diao)查報告顯示(shi)，我國弱(ruo)電(dian)(dian)(dian)電(dian)(dian)(dian)纜(lan)(lan)行(xing)業(ye)產(chan)(chan)值(zhi)規模有望(wang)超過電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)行(xing)業(ye)總產(chan)(chan)值(zhi)的1/3。按2013年電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)行(xing)業(ye)產(chan)(chan)值(zhi)規模超過1.3萬億來(lai)算，弱(ruo)電(dian)(dian)(dian)電(dian)(dian)(dian)纜(lan)(lan)的年產(chan)(chan)值(zhi)將超過4000億。
