Abstract

The invention discloses a cable with multiple moisture-proof devices, includes four sets of solid copper wires, each of the solid copper wires is sequentially coated with an insulating layer, The fourgroups of solid copper wires are coated with an inner sheath, the inner sheath and the solid copper wires are filled with polyethylene-polypropylene fibers with waterproofing properties, the inner sheath is wound with a dry water stop belt, and the outer layer of the dry water stop belt is coated with an armor layer and an outer sheath in turn. By covering each solid copper wire in the cable witha waterproof layer and winding a dry waterstop on the entire conductor, the double moisture-proof effect is realized, and the cable can be used efficiently and stably for a long time.

Description

Technical field [0001] The present invention relates to the technical field of cable manufacturing, in particular to a cable with multiple moisture-proof devices. Background technique [0002] The shape of a cable is similar to a rope, and it is usually formed by twisting multiple groups of wires. Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a high-insulation coating; the cables are mostly erected in the air Or installed underground or underwater for telecommunications or power transmission; in order to ensure the normal and stable operation of the cable, the cable must have basic safety properties, such as abrasion resistance, flame resistance, and fire resistance. At present, with the aging and wear of the outermost layer of common cables, water vapor will slowly enter the cable, aggravating the damage of the cable, greatly shortening the service life of the cable, and preventing the cable from being ...
