.產品簡介：本產品適用于額定電壓500V及以下對于防干擾性要求較高的電子計算機和自動化設備連接用電纜。
電纜地線芯絕緣采用具有抗氧老化性能的K型B類低密度聚乙烯。
聚乙烯的絕緣電阻高，耐電壓好，介電系數和介質損耗受溫度和頻率的影響小，能滿足傳輸性能的要求，還能確保電纜的使用壽命。
為了減少回路間的相互串擾和外部干擾，電纜采用了屏蔽結構，電纜的屏蔽要求是，根據不同使用場合分別采用：對絞組合屏蔽，對絞組成電纜的總屏蔽、對絞組合屏蔽后總屏蔽等方法。
屏蔽材料有銅絲、銅帶、鋁箔/塑料復合帶三種。
屏蔽對與屏蔽對具有較好的絕緣性能，電纜在使用中若屏蔽對與屏蔽對之間出現電位差時，不會影響信號的傳輸效果。
