Highly insulated and shielded twin-core radio frequency cable

The utility model discloses a highly insulated and shielded twin-core radio frequency cable comprising two alloy conductors. The cross section of each of the two alloy conductors is in the shape of a semi-circular arc. Each alloy conductor is successively wrapped with a fire-resistant mica tape insulation layer and a silane crosslinked ethylene-propylene rubber insulation layer outside to form an insulation cable core. The insulation cable cores are oppositely and parallel arranged in a vertical direction to form a cable core, the cable core is successively wrapped with a braided-shield layer and a winding layer outside, the winding layer is formed by spirally wound steel wires, the spirally-twisted distance is less than 3.5 mm, and a sheath layer is extruded on the outer side of the winding layer. The highly insulated and shielded twin-core radio frequency cable comprising the two alloy conductors is novel in structure and design. The design of the double insulation layers, the braided-shield layer and the s
