Communication cables are cables that transmit telephone, telegraph, facsimile documents, television and radio programmes, data and other electrical signals. Twisted by more than one pair of mutually insulated conductors. Compared with overhead open line, communication cable has the advantages of large communication capacity, high transmission stability, good confidentiality, less affected by natural conditions and external interference.
　　6：产品性能和参数：导体结构：由7/1.04mm软铜线绞合而成绝缘：绝缘采用交联聚乙烯，绝缘厚度1.0mm，绝缘电阻可以保证在10000MΩ/km以上。护套：绝缘采用低密度聚乙烯黑色护套，护套厚度1.8mm,从而保证了电缆优良的绝缘性能，防水性能和防老化性能。

凡是装配过电气控制线路或控制柜的同行，想必都对不可或缺的“急停”按钮印象深刻。这种用在紧急情况下的按钮，多为红色蘑菇头自锁式，在整个控制系统中非常醒目。不少同行认为该按钮只是使用常闭触点串入电控系统的控制回路，在其按下后用以切断整个控制回路电源，使线路当中的各个线圈失电，间接控制主回路断电停机。但有时“急停”按钮的功能绝非上述那样简单，如果不结合生产实际情况，恐怕该“急停”按钮非但无法起到相应作用，还会造成不必要的事故。
