The industrial moistureproof crosslinked polyethylene cable has advantages of excellent waterproof performance, corrosion-proof performance and long service life.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable.
Background technology
At present, along with the development of science and technology, people are also increasing to the demand of cable, and general cable mainly comprises conductor, insulating barrier and oversheath, but this structure is comparatively simple, can only use under general operational environment, but along with the difference of operational environment, people are also improving greatly to the requirement of cable, such as under the environment that some are moister, general cable after a long time use, moisture in air can penetrate into cable inside, thus the insulating barrier causing cable inside to arrange is breakdown, serious curtailment useful life of cable, considerably increase entreprise cost, also potential safety hazard can be there is.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable.
The present invention takes following technical scheme to realize: a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body inside is provided with many conductors; Described conductor closely wraps up one deck protective sleeve outward; Described protective sleeve and conductor form cable core jointly; Described cable core closely extrudes a layer insulating outward; Gap portion between described insulating barrier and cable core is provided with multiple guide core; And described guide core respectively with insulating barrier and cable core tangent; Described cable core, gap portion between insulating barrier and guide core are provided with packed layer; Described insulating barrier closely extrudes one deck screen outward; Described screen is extruded with coat of metal, water blocking layer and armour from inside to outside successively; Described armour closely extrudes one deck oversheath outward.
Above-mentioned a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, described conductor is closed by multiply nickel-clad copper skein silk to form.
Above-mentioned a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, described insulating barrier is made up of cross-linking polyethylene materials.
