Abstract
The utility model discloses an antistatic oil-proof shielded reinforced digital line, and belongs to the technical field of digital communication transmission carriers. Each wire is formed by wrapping a nylon insulating layer outside conductors. Every two wires are twisted to form a paired group. 1 to 100 paired groups are stranded and form a line core together with a filler. A wrapping tape layer, a shielding layer and a composite sheath layer are sequentially wrapped outside the line core. A grounded copper wire is directly arranged outside the wrapping tape layer. The shielding layer wraps the wrapping tape layer and the grounded copper wire. A nylon sheath layer is extruded outside the shielding layer. A braided protective layer is braided outside the nylon sheath layer to wrap the nylon sheath layer to form the composite sheath layer. The insulating layers and the sheath layer are made of an antistatic oil-proof material. The shielding layer wrapped by carbon fiber shielding paper and shielding grounding measures are adopted, so that the antistatic performance and oil-proof performance of the digital line are ensured. Aramid yarns are filled, and the protective layer is braided by polyimide fibers, so that the tensile strength is strengthened, the flexibility is improved, the mechanical properties of the digital line are improved, and the digital line is applied to a digital communication system in a severe environment.
