SDV50-7-3型微波馈电电缆是一种稳相微波电缆,其结构比其它的微波电缆设计得合理,采用了聚乙烯螺旋绝缘体作支撑内导体的填充料,使其空心而且又保持同轴,还可充气维护。外导体采用皱纹铜管。这种结构屏蔽性能好,只要插头座装置得好,几乎没有泄漏。这种电缆可用作微波通讯系统主
SDV50-7-3-type microwave feed cable is a steady-phase microwave cable, the structure of the microwave cable than other reasonable design, the use of polyethylene spiral insulator to support the inner conductor filler to make hollow and keep the same Shaft, but also inflatable maintenance. Outer conductor corrugated brass. This structure shielding performance, as long as the plug seat device is good, almost no leakage. This cable can be used as the main microwave communication system
