Abstract
The invention discloses a damp-proof high-temperature-resistant power cable. The damp-proof high-temperature-resistant power cable comprises a cable body, wherein the cable body comprises multiple conductors, an insulation layer, a shielding layer and an outer sheath; the cross section of the cable body is of a round structure; the multiple conductors are arranged inside the cable body; cable core protection layers wrap the conductors; the cable core protection layers and the conductors form a cable core; the insulation layer is extruded outside the cable core; a filling layer is arranged in the gap between the insulation layer and the cable core; the shielding layer is extruded outside the insulation layer; a waterproof layer and a fire-resistant layer are sequentially extruded outside the shielding layer from inside to outside; the outer sheath is tightly extruded outside the fire-resistant layer. The damp-proof high-temperature-resistant power cable has the advantages that the waterproof performance and the corrosion resistance are superior, the service life is long and the like.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of moistureproof high-temperature-resistant power cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as in industry, the cable used in the field such as electric power and colliery, high all especially to the requirement of the high pressure resistant and diamagnetic jamming performance aspect of cable, very high to the requirement of cable in the field that some are special, but existing cable because of its structural design unreasonable, in actual applications, partial cables can not be competent at the comparatively severe work of some environment, long-time use makes cable skin damaged, not only make the transmission distortion of signal, also can bring a lot of inconvenience to maintenance personal, cause the loss that enterprise is great.
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 moistureproof high-temperature-resistant power cable.
The present invention takes following technical scheme to realize: a kind of moistureproof high-temperature-resistant power cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body cross section is circular configuration; Described cable body inside is provided with many conductors; Described conductor outer wrapping one deck core protective layer; Cable core is formed between described core protective layer and conductor; A layer insulating is extruded outside described cable core; Between described insulating barrier and cable core, gap portion is provided with packed layer; One deck screen is extruded outside described insulating barrier; Described screen is extruded with watertight composition and flame retardant coating from inside to outside successively; Described flame retardant coating closely extrudes one deck oversheath outward.
The moistureproof high-temperature-resistant power cable of above-mentioned one, described conductor forms by multiply tinned copper wire is stranded.
The moistureproof high-temperature-resistant power cable of above-mentioned one, described flame retardant coating is fire-resistant isinglass belt.
The moistureproof high-temperature-resistant power cable of above-mentioned one, described watertight composition is made up of polyester fiber.
The moistureproof high-temperature-resistant power cable of above-mentioned one, described packed layer is made up of non-net polypropylene tearing material of opening.
The present invention has following beneficial effect in sum: this cable has the advantages such as outstanding water proofing property, corrosion resistance and long service life, described packed layer is made up of non-net polypropylene tearing material of opening, describedly non-ly open the heat absorption capacity coefficient that net polypropylene tearing material can reduce material, effectively prevent the overheated burning of cable, improve the resistance to elevated temperatures of cable, its useful life is extended greatly.

Wherein: 1, cable body; 2, conductor; 3, core protective layer; 4, packed layer; 5, insulating barrier; 6, screen; 7, watertight composition; 8, flame retardant coating; 9, oversheath.
Embodiment
As shown in Figure 1, a kind of moistureproof high-temperature-resistant power cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 5, screen 6 and oversheath 9, and described cable body 1 cross section is circular configuration; Described cable body 1 inside is provided with many conductors 2; Described conductor 2 outer wrapping one deck core protective layer 3; Cable core is formed between described core protective layer 3 and conductor 2; A layer insulating 5 is extruded outside described cable core; Between described insulating barrier 5 and cable core, gap portion is provided with packed layer 4; One deck screen 6 is extruded outside described insulating barrier 5; Described screen 6 is extruded with watertight composition 7 and flame retardant coating 8 from inside to outside successively; Described flame retardant coating 8 is outer closely extrudes one deck oversheath 9.
Described conductor more than 2 tinned copper wire is stranded to be formed, and not only substantially increases the operating efficiency of cable, also makes its work more stable, and described conductor 2 structure is easy to processing, making length is unrestricted, has certain flexibility and bendability during use, facilitates the laying of workpeople; Described core protective layer 3 can effectively protect conductor 2, prevents conductor break; Described packed layer 4 is made up of non-net polypropylene tearing material of opening, and describedly non-ly opens the heat absorption capacity coefficient that net polypropylene tearing material can reduce material, effectively prevents the overheated burning of cable, improve the resistance to elevated temperatures of cable, its useful life is extended greatly.
The above is the embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
