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。
The product is suitable for electronic computers and automation connection cables with high anti-interference requirements for rated voltage of 500V and below. The insulation of the cable ground wire core adopts K-type B-class low-density polyethylene with performance. Polyethylene has high insulation resistance, good voltage resistance, low dielectric constant, and minimal temperature and frequency effects on dielectric loss. It not only meets the requirements of transmission performance, but also ensures the service life of cables.
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。
In order to reduce mutual crosstalk and external interference between circuits, the cable adopts a shielding structure. The shielding requirements for cables are based on different occasions, using methods such as twisted pair combination shielding, total shielding of twisted pair cables, and total shielding after twisted pair combination shielding.
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。
There are three types of shielding materials: round copper wire, copper strip, and aluminum strip/plastic composite strip. Shielding pairs have good insulation performance, and if there is a potential difference between shielding pairs during cable use, it will not affect the quality of signal transmission.
