同轴电缆
什么是同轴电缆以及如何识别它?
同轴电缆被认为是一种低损耗、高隔离度的宽带传输线. Coaxial cable consists of two concentric cylindrical conductors separated by a dielectric spacer. 沿同轴电缆分布的电容和电感产生分布阻抗, 或特性阻抗, 整个结构. The resistive losses distributed along the coaxial … 阅读更多
什么是同轴电缆以及如何识别它?
同轴电缆是电线和信号传输线, 一般是由四层材料造成的. 最里面是一根导电铜线, 线的外面有一层塑料包围着, 它是绝缘体和电介质用途. 外面有绝缘体，还有一层薄薄的网状导电体, generally … 阅读更多
The Voltage Rating Coaxial Ground Cable
The voltage level of the coaxial grounding cable should be determined according to the induced potential of the cable line. According to the past design experience, the voltage level of the coaxial grounding cable is generally 10kV; the cross-section of the coaxial grounding cable should be strictly selected according to the grounding current of the … 阅读更多
