The invention relates to a multi-shielded signal transmission cable. The cable comprises a conductor, an insulating layer, a binding layer, a shielding layer, a metal armor layer and an outer sheath,wherein the insulating layer is arranged outside the conductor to form an insulating wire core; the binding layer is arranged between the conductor and the insulating layer; the shielding layer is arranged outside the insulating wire core; the shielding layer comprises a first shielding layer, a second shielding layer and a third shielding layer which are arranged from inside to outside; the metalarmor layer is arranged outside the shielding layer; the outer sheath is arranged outside the metal armor layer; the surface of the metal armor layer is coated with a moisture-proof and anti-corrosion coating layer; and a galvanized steel wire bearing lifting wire is arranged in the outer sheath. The cable is simple in structure, stable in signal transmission, high in shielding effect, moisture-proof, water-proof, wear-resistant and corrosion-resistant.
Description
technical field [0001] The invention relates to a cable, in particular to a multi-shielding signal transmission cable. Background technique [0002] In recent years, the sustained and rapid growth of my country's economy has provided a huge market space for the wire and cable industry. Most of the power cables and control cables currently used are independent cables. The application field and scope are fixed, and the performance of the cables is also fixed and single. When laying multiple cables, it will occupy a large construction area and the construction workload will also increase. costs. Contents of the invention [0003] In order to solve the above problems, the present invention provides a multi-shielded signal transmission cable with simple structure, stable signal transmission, good shielding effect, moisture-proof and water-proof, wear-resistant and corrosion-resistant. [0004] The technical solution of the present invention is: the cable includes a conductor,...
