Three Servos Active Type Taping Machine for Phase Stable Cable

The military industry is the main application field for phase-stable cables, such as phased array radar, missiles, ships, and electronic warfare systems. Compared to other types of cables, phase-stable cables excel in performance indicators and flexibility. There are two types of phase stability: mechanical phase stability and temperature phase stability. Mechanical phase stability refers to the phase shift caused by the dimensional changes and structural variations of the cable components when subjected to mechanical forces such as bending or twisting. The mechanical phase stability index is influenced by bending methods and radii, and the data vary with different test methods and bending radii. For example, in phased array radar systems, the antenna units need to synchronously transmit signals to the mainframe for analysis and processing, but the distance from different positions on the antenna surface to the mainframe interface varies. A set of phase-matched cable components will take different paths from the antenna units to the mainframe interface, resulting in different numbers of bends and bending radii. Therefore, in the design process, attention should be paid to the tightness and stability of the inner conductor, insulation, and outer conductor, reducing or avoiding relative sliding between the three. Temperature phase stability refers to the performance of the cable materials and their internal interactions with temperature changes, which will affect the overall phase variation with temperature. For example, when the ambient temperature rises, the insulation material expands and its sealing performance decreases, resulting in a decrease in the dielectric constant, an increase in propagation speed and a decrease in phase. At the same time, as the temperature rises, the cable conductor expands, and its physical length also increases, resulting in an increase in phase. For instance, in the deployment of phased array radar or missiles in high-altitude areas, the large temperature difference between day and night can exceed the range that ordinary cables can withstand, resulting in significant phase changes and signal delays. High-performance coaxial cable components must have good mechanical phase stability and temperature phase stability. GEMWELL has been focusing on the innovation and research of wire wrapping machines for 20 years. Through continuous improvements, GEMWELL Three Servos Active Type Taping Machine for Parallel Pair Signal Wire has become a better choice for replacing traditional wrapping machine models and processes. The following configuration is for a standard setup with three taping heads, and users can increase or decrease the number of taping heads according to different processes. Depending on different wire diameter specifications, the specifications and types of the take-up, pay-off, and capstan can also be customized.
