Abstract
The invention discloses an anti-torque type communication cable of a flat structure. The anti-torque type communication cable comprises three data line sets, each data line set is formed by stranding two insulation line cores and a tensile core, and the insulation line cores are formed by coating conductors with inner aluminum foil lapped shielding layers and silicon rubber insulation layers. Single-core shielding power lines and twisted-pair power line sets are arranged between the adjacent data line sets, and each twisted-pair power line set is formed by twisting two single-core shielding power lines pairwise. A cable core is composed of the three data line sets, the single-core shielding power lines and the twisted-pair power line sets together, the cable core is formed in a silicon rubber outer sheath layer in an extrusion molding mode, and an anti-torque ring is arranged in the silicon rubber outer sheath layer, and is formed by knitting copper wires. Through the design of the tensile cores, an anti-torque barrel and other structures, the distortion resisting performance of the cable is improved, high-rate, low-noise and high-accuracy transmission of data is achieved after the cable is mounted in a narrow space, and the actual application environment is met.
