In the combination, a control line unit group 4 for control signal transmission and a power line unit group 6 for power supply are added to achieve the characteristics of compact composite transmission structure, small outer diameter, simple one-time laying and installation, and realize lightweight, intensive and miniaturized.
[0029] In this embodiment, the data line unit group 5 is composed of two first conductors 401, a first insulating layer 402, two cores 403 and a second shielding layer 404. The first insulating layer 402 is wrapped around the outer wall of the silver-plated copper-clad aluminum alloy wire core inner conductor to form a first data line. The first data line and the core 403 are both located inside the second shielding layer 404. The two first data lines are arranged oppositely in the second shielding layer 404, and the two cores 403 are arranged oppositely in the second shielding layer 404. The two first data lines and the core 403 are combined to form a cross-shaped structure. The first conductor 401, the second conductor 501, and the third conductor 601 are all silver-plated copper-clad aluminum alloy wire core inner conductors. The materials used in the first shielding layer 2, the second shielding layer 404, and the third shielding layer 503 are all foamed polytetrafluoroethylene, and the filler material is foamed polytetrafluoroethylene. The first shielding layer 2, the second shielding layer 404, the third shielding layer 503, and the fourth shielding layer 603 are all polyimide copper composite film inner shielding layers.
[0030] In this embodiment, the control line unit group 4 is composed of a second conductor 501, a second insulating layer 502 and a third shielding layer 503; a second insulating layer 502 is provided outside the second conductor 501 to form a second data line, and two second data lines constitute the core of the control line unit, and the core of the control line unit is located inside the third shielding layer 503.

[0034] The present invention adopts high-quality high-temperature insulating materials and metal materials, and through reasonable structural design, optimizes and improves the transmission performance of the data transmission cable under the original high-temperature and acid-alkali resistance. At the same time, a composite structure is adopted, that is, the original data transmission cable, control cable and power supply cable are combined into one, which reduces the number and space of installation and laying, and reduces weight and size, laying a good foundation for the overall weight reduction of the equipment, which not only reduces energy consumption, but also improves the running distance and loading capacity of the equipment.
[0035] The inner conductor of the present application adopts a silver-plated copper-clad aluminum alloy wire core, and the conductor can achieve a 65% weight reduction, so that the cable has good electrical and mechanical physical properties such as light weight and high conductivity. The insulation layer of the data line unit group 5 selects a foamed polytetrafluoroethylene high-temperature material with a small dielectric constant, and the insulation density is 0.6g / cm3. The insulation part can achieve a 71% weight reduction, which can reduce the dielectric constant and volume of the medium, thereby reducing transmission loss and improving transmission efficiency. The data line unit group 5 uses a foamed polytetrafluoroethylene core filling 403, which effectively reduces the overall dielectric constant. In order to improve the temperature resistance level of the product, the sub-shielding and overall shielding of the unit group adopt polyimide copper composite film. Compared with ordinary shielding, the shielding layer can reduce 60% of the weight. At the same time, the sub-shielding layer and + overall shielding composite shielding structure are adopted, which can effectively improve the signal anti-interference ability and the crosstalk defense between the line groups. The sheath 1 adopts polytetrafluoroethylene to meet the strict requirements of high temperature, acid and alkali and other complex use environments.
