MIL-DTL-17J涵盖了具有实心和半实心介电芯、单芯、双芯和双芯内导体的柔性和半刚性电缆。本规范涵盖的电缆主要用作传输线，以连续或间歇性地在简单的电力传输中传导能量。通常，这些电缆设计用于从相对较低的频率到频谱的微波和雷达区域中的较高频率的低损耗、稳定操作。电缆也可以用作电路元件、延迟线或阻抗匹配装置。这些电缆是根据第3节规定的可靠性保证计划提供的。

MIL-DTL-17J covers flexible and semirigid cables with solid and semisolid dielectric cores, with single, dual and twin inner conductors. Cables covered by this specification are primarily intended for use as transmission lines to conduct energy in a simple power transfer continuously or intermittently. In general, these cables are designed for low-loss, stable operation from the relatively low frequencies through the higher frequencies in the microwave and radar regions of the frequency spectrum. Cables may also be used as circuit elements, delay lines or impedance matching devices. These cables are supplied under a reliability assurance program as specified in section 3.
