　　1．用 途；广州市东方电线电缆厂，本产品适用于额定电压500v及以下对于防干扰性要求较高的电子计算机和自动化连接用电缆。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。电缆的屏蔽要求是根据不同场合分别采用: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。

　　屏蔽材料有圆铜线，铜带、铝带/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屏蔽对之间出现电位差时，不会影响信号的传输质量

　　guangzhou dongfang wire cable plant this product is applied to rated voltage 500v and below a higher requirement for tamper-resistant electronic computer and automation connectivity cable. ground cable core insulation used with anti-oxidant properties of k-b type low-density polyethylene. polyethylene insulation resistance of a high withstand voltage is good, small and medium dielectric constant temperature and variable frequency of loss of influence is small, not only to meet the transmission performance requirements, but also to ensure that the cable life.

　　in order to reduce the inter-loop crosstalk and external interference, shielded cable structure. cable shielding requirements are based on different occasions were used: combination of shielded twisted pair, twisted pair cables composed of the total shielding, shielded twisted pair combination of methods such as after the total shielding.

　　shielding materials are round copper wire, copper strip, aluminum strip / plastic composite tape of three. shield with the shield has good insulation properties of the cable in use of the shield, if shield potential difference between the right, it will not affect the signal transmission quality. welcome
