Abstract

The invention relates to a moisture-proof cable. The moisture-proof cable comprises a conductive wire core which is externally wrapped by an insulating protection layer. The insulating protection layer is externally wrapped by a blocking layer which is made of elastic material. The blocking layer is externally wrapped by a moisture-proof tube which is externally wrapped by an external protection layer with a water-resistant function. The moisture-proof tube is made of porous water swelling material. Negative pressure tubes are equidistantly arranged along the axial direction of the moisture-proof tube in the tube wall of the moisture-proof tube. Capillary holes are arranged on the tube wall of the negative pressure tubes. Air extraction valves are also adjacently connected on the negative pressure tubes. The air extraction valves stretch out of the external protection layer. The moisture-proof cable is relatively low in mass, exquisite in structure, great in the moisture-proof effect and convenient for later maintenance.

Description

technical field [0001] The invention relates to a cable, in particular to a cable with waterproof and moisture-proof functions. Background technique [0002] The shape of the cable is similar to a rope. It is usually twisted by multiple groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulating coating; the cable is 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 performance, such as wear resistance, flame retardancy, fire resistance, etc., and depending on the application occasion It also needs to have corresponding characteristic properties, such as insect repellency, anti-corrosion, cold resistance, etc.; the current common cables are equipped with multiple protections such as steel armor and outer protectiv...
