简介:
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[1]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。
Introduction:
This product is suitable for electronic computers with a rated voltage of 500V and below, as well as cables for automation connections that require high anti-interference requirements. The insulation of the cable ground wire core adopts K-type B class with oxidation resistance.
Low density polyethylene has high insulation resistance, good voltage resistance, low dielectric coefficient, and minimal influence of medium loss temperature and frequency variation. It not only meets the requirements of transmission performance, but also ensures the service life of the cable.
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 composed cables, and total shielding after twisted pair combination shielding.
cable
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, aluminum strip/plastic composite strip. Shielded pairs have good insulation performance, and if there is a potential difference between shielded pairs during cable use, it will not affect the transmission quality of the signal.
