Abstract

The invention discloses a phase-regulated cable for spaceflights and a method for preparing the same. The phase-regulated cable for spaceflights is characterized by comprising an inner conductor, an insulation layer, outer conductors and sheaths which are all coaxially and are sequentially arranged from inside to outside. The method for preparing the phase-regulated cable for spaceflights comprises the following steps of forming the inner conductor by drawing or twisting a single or multiple silver-plated copper wires; forming the insulation layer by using a lapping production line to manufacture a polytetrafluoroethylene micro-porous thin film and then pressing the thin film; forming an outer conductor I by using the lapping production line to lap a silver-plated copper flat belt and then rolling the flat belt with round rollers; forming an outer conductor II by lapping an aluminum foil and a polyimide composite belt; forming an outer conductor II by braiding copper-plated round copper wires; and forming a sheath I and a sheath II by using the lapping production line to lap a polyimide duplex polytetrafluoroethylene thin film and a polytetrafluoroethylene sealing tape; and thus obtaining a finished product of a phase-regulated cable. The phase-regulated cable for spaceflights small in laying bending radius, phase-regulated, low in loss and low in standing wave, and has strong resistance to high and low temperatures and radiation, improved anti-interference performance and good flame resistance.

Description

technical field [0001] The invention relates to a phase-stable cable for aerospace, which is applicable to outer space environments such as aerospace, space station, and Mars exploration, and used for signal transmission of instruments and meters. [0002] The invention also relates to a preparation method of a phase-stable cable for aerospace. Background technique [0003] At present, the most advanced radio frequency cables in the world are phase-stable cables, which are divided into solid and foamed cables according to the dielectric composition. According to the softness, it is divided into semi-flexible, semi-steel, and soft RF cables. According to phase and loss requirements, it can be divided into low-loss cables and phase-stable cables. Ordinary RF cables have heavy weight, large loss, large standing waves, phase difference, poor UV resistance, and require a large laying space, which is not conducive to installation. At the same time, an anti-UV protection device i...
