20對(duì)通信電纜線序色譜認(rèn)識(shí)表
通常通信電纜分為：10對(duì)，20對(duì)，30對(duì)，50對(duì)，100對(duì)，200對(duì)，300對(duì)，400對(duì)，500對(duì)，600對(duì)，700對(duì)，800對(duì)，1000對(duì)，1200對(duì)，1600對(duì)，1800對(duì)，2400對(duì)通信電纜。
天津市電纜總廠一分廠提供通信電纜色譜供通信初學(xué)者學(xué)習(xí)使用，通信電纜色譜分序始終共有10種顏色組成，由5種主色和5種次色；5種主色和5種次色又組成25種色普，不管通信電纜對(duì)數(shù)多大，通常大對(duì)數(shù)通信電纜都是按25對(duì)色為一小把標(biāo)識(shí)組成。
5種主色：白色、紅色、黑色、黃色、紫色
5種次色：蘭色、桔色、綠色、棕色、灰色
還是舉例說(shuō)明：
