100對(duì)市內(nèi)通訊電纜結(jié)構(gòu)

通信電纜主要用于近距音頻通信和遠(yuǎn)距的高頻載波和數(shù)字通信,其種類、型號(hào)及規(guī)格繁多。主要有聚烯烴絕緣聚烯烴護(hù)套市內(nèi)話纜,導(dǎo)體直徑按標(biāo)準(zhǔn)規(guī)定采用0.32mm、0.40mm、0.50mm、0.60mm和0.80mm。2對(duì)4對(duì)5對(duì)8對(duì)10對(duì)15對(duì)20對(duì)25對(duì)30對(duì)50對(duì)80對(duì)100對(duì)。100對(duì)的通信電纜里有4種標(biāo)識(shí)線，第一的25對(duì)是用“白蘭”標(biāo)識(shí)線纏著的，第二的25對(duì)是用“白桔”標(biāo)識(shí)線纏著的，第三的25對(duì)是用“白綠”標(biāo)識(shí)線纏著的，第四的25對(duì)是用“白棕”標(biāo)識(shí)線纏著的。通信電纜由很多絕緣導(dǎo)線絞合而成的，因此在對(duì)通信電纜進(jìn)行施工操作的時(shí)候就需要進(jìn)行辨別，為了方便辨別，以此來對(duì)通信電纜內(nèi)的導(dǎo)線功能進(jìn)行識(shí)別。今天我們向大家簡(jiǎn)單介紹一下相關(guān)的色譜知識(shí)。電纜的纜芯色譜可分為普通色譜和全色譜兩大類。1.普通色譜2.全色譜 。通信電纜色譜共有10中顏色組成，即5中主色和5中次色，主色和次色之間能夠相互組成共25種顏色。25中顏色能通信電纜的色彩需求，不管電纜的對(duì)數(shù)有多大，需要傳輸多大的信息和信號(hào)。5種主色為：白、紅、黑、黃、紫  5種次色為：蘭、桔、綠、棕、灰。下面我們舉例說明通信電纜進(jìn)行識(shí)別的時(shí)候注意事項(xiàng)。
