Abstract
The utility model discloses a high-temperature fireproof shielding control cable, which is composed of insulated power line cores 1, insulated power line cores 2, a pair-twisted group copper braided shielding layer and a fluoroplastic outer sheath, wherein each insulated power line core 1 is formed by extruding a fluoroplastic insulating layer on two multi-stranded silver-copper alloy conductors; each insulated power line core 2 is formed by extruding a crosslinked polyvinyl chloride insulating layer on three multi-stranded silver-copper alloy conductors and a tensile-resistant steel wire; the three insulated power line cores 2 are tightly extruded, and the three insulated power line cores 1 are arranged in gaps between the outer sides where every two insulated power line cores 2 are in contact to form a regular triangle shape; the pair-twisted group copper braided shielding layer is extruded on the insulated power line cores 1 and the insulated power line cores 2 to form a cable core; a fire-resistant filling layer is arranged in a gap inside the cable core; and the fluoroplastic outer sheath is coated on the pair-twisted group copper braided shielding layer. The high-temperature fireproof shielding control cable has good radiation resistance and high temperature resistance, and has excellent fireproof resistance, shielding performance and mechanical performance.
Description
Technical field
The utility model relates to field of aerospace technology, relates in particular to a kind of high temperature fire-proof shield control cables.
