Description

technical field [0001] The invention relates to the field of photoelectric hybrid cable manufacturing, in particular to a super-strong, super-flexible, high-temperature-resistant photoelectric hybrid cable, a manufacturing method thereof, and a wrapping machine. Background technique [0002] Compared with a single optical cable or electric cable, the optical-electrical hybrid cable has a wider application environment because one cable can transmit optical signals and electrical signals at the same time. [0003] In the prior art, the optical-electrical hybrid cable structure includes a cable core and an outer sheath covering the cable core. The cable core includes a central strengthening core, and a number of electric wires (power for transmission equipment), signal transmission lines and optical fibers are distributed outside the central strengthening core. The cable core is filled with filling rope and water blocking material. The outer sheath consists of polyester tape ...

AI Technical Summary

Problems solved by technology

[0004] Due to the complex structure and the limitation of the characteristics of the materials used, the optical-electrical hybrid cable of the prior art has many defects: First, the optical fiber surface cladding adopts an extrusion process and double-layer coating, which not only increases the production cost but also due to the optical-electrical hybrid cable. There are many components and production processes in the cable, and there are many hidden dangers in quality. The waterproof ointment is filled between the core and the cladding, which increases the cost and increases the structural size, which affects the bending performance; second, the outer sheath layer uses The polyethylene or polyvinyl chloride material is a high molecular polymer with a certain thickness, which increases the volume and has poor high temperature resistance, so that this kind of photoelectric hybrid cable can only be used in ordinary fire-proof environments (common hybrid cables use The environment is -40-70 degrees), and the poor bending performance of the polymer material after polymerization also affects the soft performance of the photoelectric hybrid cable; third, due to the use of metal material corrugated steel belt layer and steel wire central reinforcement core to ensure the photoelectric hybrid cable The mechanical properties of the cable not only increase the volume and weight but also affect the softness of the optical hybrid cable

[0005] The above-mentioned photoelectric hybrid cable is affected by its structure and cannot be used in high temperature, strong stress and narrow environments. When such application environments appear, such as aviation, aerospace, and navigation, when used inside aircraft, ships, and large computers , only separate optical cables or cables can be used to transmit optical signals and electrical signals respectively
