　　DJVP2VR DJYP2VR DJYJP2VR 铜塑复合膜分对屏蔽软结构 。

　　所谓的差分信号是指一根线以正电平方式传输信号，另外一根线以负电平方式传输同一信号，当线路中出现干扰信号时，其对两根线的影响是相同的，因而在接收端还原差分信号时就可以屏蔽掉该干扰信号（可以理解为差分的两路信号执行减运算）。

　　一般信号电缆传输的信号很小，为了避免信号受到干扰，信号电缆外面有一层屏蔽层，包裹的导体的屏蔽层，一般为导电布，编织铜网或铜泊（铝），屏蔽层需要接地，外来的干扰信号可被该层导入大地，避免干扰信号进入内层导体干扰同时降低传输信号的损耗。

　　电缆地线芯绝缘采用具有抗氧化性能的K型B类低密度聚乙烯。聚乙烯的绝缘电阻高，耐电压好，介电系数小和介质损耗温度和变频率的影响也小，不但能满足传输性能的要求，而且能确保电缆的使用寿命。为了减少回路间的相互串扰和外部干扰，电缆采用屏蔽结构。
