通訊電纜介紹;
1 通信電纜分類以及用途
從事通信電纜工程設(shè)計(jì)、施工和維護(hù),首先對(duì)通信電纜產(chǎn)品要有清晰、準(zhǔn)確的認(rèn)識(shí)。
2.1.1全塑電纜的分類
1.按電纜結(jié)構(gòu)類型分——非填充型和填充型。
2.按導(dǎo)線材料分——銅導(dǎo)線和鋁導(dǎo)線;
3.按芯線絕緣結(jié)構(gòu)分——實(shí)心絕緣、泡沫絕緣、泡沫/實(shí)心皮絕緣;
4.按線對(duì)絞合方式分——對(duì)絞式和星絞式;
5.按芯線絕緣顏色分——全色譜和普通色譜;
6.按纜芯結(jié)構(gòu)分——同心式(層絞式)、單位式、束絞式、SZ絞;
7.按屏蔽方式分——單層涂塑鋁帶屏蔽、多層鋁及鋼金屬帶復(fù)合屏蔽,而屏蔽帶又分繞包和縱包;
8.按護(hù)套分——單層塑料護(hù)套、雙層塑料護(hù)套、綜合護(hù)套、粘接護(hù)套、密封金屬/塑料護(hù)套和特種護(hù)套;
9.按外護(hù)層分——單層、雙層鋼帶鎧裝和鋼絲鎧裝塑料護(hù)層;
10.按用途分——傳輸模擬信號(hào)和傳輸數(shù)字信號(hào);
11.按敷設(shè)方式分——架空、管道、直埋、水底電纜等。
2.1.2全塑電纜的型號(hào)
電纜型號(hào)是識(shí)別電纜規(guī)格程式和用途的代號(hào)。按照用途、芯線結(jié)構(gòu)、導(dǎo)線材料、絕緣材料、護(hù)層材料、外護(hù)層材料等,分別用不同的漢語(yǔ)拼音字母和數(shù)字來(lái)表示,稱為電纜型號(hào)。按照原郵電部行業(yè)標(biāo)準(zhǔn)(YD2001—92),
