Communication wire suitable for vacuum environment and production process

Abstract

The invention discloses a communication wire suitable for the vacuum environment, which comprises a cable body, wherein the cable body comprises communication lines, power transmission lines, an insulating layer, a braided layer and an outer sheath, every two communication lines are twisted into one diagonal line, the number of the communication lines is at least four, every two communication lines and power transmission lines and one diagonal line are arranged at intervals, the number of the power transmission lines is at least four, an annular structure is defined by the two diagonal lines and the four power output lines, the outer surface of each communication line and the outer surface of each power transmission line are tightly wrapped by the insulating layer, the braided layer is arranged on the outer sides of the communication lines and the outer sides of the power transmission lines, and the outer surface of the braided layer is tightly wrapped by the outer sheath. The communication lines and the power transmission lines are arranged separately, an inner wrapping tape layer is arranged on the outer side of the communication line, and the outer wrapping tape layer and the braided layer are wrapped through a corresponding production process, so that normal operation of signal transmission and power transmission of the communication line in the vacuum environment is ensured, embrittlement of the communication line due to the vacuum environment is avoided, and the industry blank is filled.

Description

technical field [0001] The invention belongs to the technical field of communication wires, in particular to communication wires used in a vacuum environment, and specifically relates to a communication wire suitable for a vacuum environment and a production process. Background technique [0002] At present, there are almost no cables in the domestic wire and cable industry that can be used in ultra-vacuum environments. When the vacuum temperature is below -220°C or above 310°C, the short molecular chains of conventional materials are relatively large in the environment described below, and the total mass loss is > 2.0%. , volatile condensables and brittleness make it almost impossible to realize signal transmission and power transmission in an ultra-vacuum environment, which severely restricts the needs of military industry, aerospace field, and vacuum medical treatment in this regard. Contents of the invention [0003] In order to solve the above problems, the present...
