.產(chǎn)品簡介：本產(chǎn)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(shè)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(shù)和介質(zhì)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(jié)構(gòu)，電纜的屏蔽要求是，根據(jù)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(fù)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(xiàn)電位差時，不會影響信號的傳輸效果。
