产品简介 Product synopsis.　　　　

　　本产品适用于额定电压500V以下对于防干扰扰要求较高的电子计算机和自动化设备连接用电缆。电缆地线芯绝缘采川具有抗氧老化性能的B类低密度聚乙烯。聚乙烯的绝缘电阻高，耐电压好，介电系数和介质损耗受温度和频率的影响也小，能满足传输性能的要求，还能确保电缆的使川寿命。
　　为了减少回路的相互串扰和外部干扰，电缆采川了屏蔽结构。电缆的屏蔽要求是，根据不同使用场合分别采用；对绞组合屏蔽、对绞组成电缆的总屏蔽、对绞组合屏蔽后总屏蔽等方法。
　　屏蔽材料有铜丝、钢带、铜箔/塑料复合带三种。屏蔽对与屏蔽对具有较好的绝缘性能，电缆在使用中若屏蔽对与屏蔽之间出现电位差时，不会影响信号的传输质量。

　　The product is used for connecting cable in the electronic computer and automatic that demands high arti-interference and its rated voltage should be 500 or below.The cable earth wire core insulation adopts Model K Class B low-density polyethylene with antioxidant and anti-aging petformance.The polyethylene is provided with high insulated resistance,fine withstand voltage.And the dielectric coefficient and dielectric loss are little affected by the temperature and frequency.It can meet the demand of transmission performance and also can guarantee the service life of the cable.
　　The cable adopts shield structure in order to reducing mutual interference and external interference among the loops.According to different operating places,the demand of the cable shield separately adopts:the methods of paired composite shield,total shield of paired composed cable,total shield after paired composite shield etc.
