铁路数字信号电缆电气性能的影响因素探讨

电气性能是铁路数字信号电缆生产企业及产品质量监督检验部门对铁路数字信号电缆产品质量的重要判断项目。因此，对铁路数字信号电缆电气性能的测量要求准确，以使客户了解产品的质量。但电气性能项目中有些重要指标与电缆的温度有非常大的关系，如电缆测试温度判断不准会造成电气性能测试值的差异。介绍了铁路数字信号电缆电气性能检测中的一种重要的确定电缆温度的方法。

Exploration on the Factors Influencing Performance of Railway Digital Signal Cable

Electric property is the important item used to find out the quality of railway digital signal cable products by manufacturers and product quality supervision agency. Therefore, it is necessatT to accurately measure the electric property of railway digital signal cable in order to let the clients know the production quality. However, some important indicators on electric property is heavily influenced by the temperature. If the temperature when the cable is tested is not properly judged, deviation will exist in the measurement results of electric property. The authors introduce an important method used to find out the temperature when the electric property of railway digital signal cable is tested.
