The invention relates to the technical field of cables, in particular to a low-noise coaxial cable with high moisture-proof performance, comprising a twisted body, the twisted body includes an inner conductor, an inner insulating layer, an electromagnetic shielding layer and a current-guiding wire, and the inner conductor The two wires are twisted into one strand, and the outer side of the inner conductor is wrapped with an inner insulating layer, the outer side of the inner insulating layer is wrapped with an electromagnetic shielding layer, and a conductive body is interspersed between the inner insulating layer and the inner wall of the electromagnetic shielding layer, The outer side of the electromagnetic shielding layer is glued with a waterproof layer, the central axis of the waterproof layer is interspersed with a reinforcing core, and the inner wall of the waterproof layer and the electromagnetic shielding layer are filled with sound-insulating fillers. The present invention transmits the attenuation value in a heavier environment. Small size, high transmission rate, waterproof and moisture-proof, sound insulation and noise reduction, stable current, cost saving and so on. |
