在系統(tǒng)信號的數(shù)據(jù)傳輸和自動化連接當中,計算機線纜作為通訊線纜的一種,起著非常重要的作用,它是由一對以上的絕緣線纜組成,數(shù)個絕緣導(dǎo)體或體絞線的線纜芯和維護線纜芯免遭濕氣和設(shè)備破壞的外護線套構(gòu)成。隨著科學(xué)信息技術(shù)的發(fā)展,使得計算機電纜得到了更加廣泛的應(yīng)用。
計算機電纜主要用于以電子計算機為主的自動化控制系統(tǒng),以及檢測用的儀器儀表當中,例如電力、石化、冶金等行業(yè),額定電壓500伏以下的對于防干擾性能需求比較高的自動化連接使用。根據(jù)使用的不同場合,計算機電纜屏蔽層通常分別采用分屏蔽、總屏蔽、次屏蔽加一般屏蔽等,通常情況下根據(jù)用戶的不同需求和具體使用環(huán)境,總屏蔽往往采用由金屬絲編織和金屬帶纏繞的兩層復(fù)合屏蔽方式。
