Abstract
The present invention relates to a cold-resistant waterproof coaxial cable which comprises a conductor (1) and the following components that are successively coated outside the conductor (1): an insulating layer (2), a shielding layer (3) and an inner protective layer (4). An outer protective layer (5) which is prepared through mixing polyethylene and carbon black is coated outside the inner protective layer (4). The cold-resistant waterproof coaxial cable of the invention has high cold resistance and can be used at a low temperature of -40 DEG C. The cold-resistant waterproof coaxial cable has high corrosion resistance and high acid/alkali resistance. Simultaneously a plurality of protective layer are arranged outside the conductor of the cable. The cold-resistant waterproof coaxial cable has high water resistance and is not affected by the wet environment.
Description
Technical field
The present invention relates to a kind of cable, relate to a kind of cold-resistant waterproof coaxial-cable.
Background technology
The applicability of cable and fail safe can normally transmit electric energy for using at special occasions, accurately signal transmission is very important, severe cold frost region particularly, harsh climate changes, often because cable cold tolerance does not reach instructions for use, break and open circuit, and cause signal transmission disorderly, make equipment produce misoperation, cause casualties and property badly damaged.
Summary of the invention
The technical problem to be solved in the present invention is, for the poor defect of existing cable cold resistance, provides a kind of cold-resistant waterproof coaxial-cable.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of cold-resistant waterproof coaxial-cable; comprise conductor and be coated on successively insulating barrier, screen and the inner protective layer in described conductor outside, described inner protective layer is also coated with the external protection being mixed by polyethylene and carbon black outward.
In cold-resistant waterproof coaxial-cable of the present invention, described conductor is anaerobic electrician copper.
In cold-resistant waterproof coaxial-cable of the present invention, described insulating barrier is made by low-density polyethylene material.
In cold-resistant waterproof coaxial-cable of the present invention, described screen comprises aluminium foil and proof copper-wire braided net, and described Aluminium Foil Package overlays on the outside of described insulating barrier, and described proof copper-wire braided net is coated on the outside of described aluminium foil.
In cold-resistant waterproof coaxial-cable of the present invention, described inner protective layer is made by PVC material.
Implement cold-resistant waterproof coaxial-cable of the present invention, there is following beneficial effect: screen can effectively protect conductor not to be subject to the interference of external signal, and the signal of conductor inside can not leak, and signal transmits good stability simultaneously yet.Inner protective layer can prevent that screen is oxidized or be subject to mechanical damage.External protection is mixed by polyethylene and carbon black, has good cold resistance, also has good resistance to wear and corrosion resistance simultaneously, after polyethylene and carbon black mix, is coated on the outside of inner protective layer by the mode of extrusion molding.The cold resistance of the cold-resistant waterproof coaxial-cable of the present invention is good, can under the low temperature environment of-40 ℃, use, and corrosion resistance is good, acid and alkali-resistance, and the conductor of cable has a plurality of protective layers outward simultaneously, and good waterproof performance, is not subject to the impact of wet environment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of the cold-resistant waterproof coaxial-cable of the present invention.
Embodiment
For technical characterictic of the present invention, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1, the cold-resistant waterproof coaxial-cable of the present invention comprises conductor 1, insulating barrier 2, screen 3, inner protective layer 4 and external protection 5, and insulating barrier 2, screen 3, inner protective layer 4 and external protection 5 are coated on the outside of conductor 1 from inside to outside successively.Insulating barrier 2 wraps inner conductor 1, plays the effect of insulation protection.Screen 3 can effectively protect conductor 1 not to be subject to the interference of external signal, and the signal of conductor 1 inside can not leak yet simultaneously, and signal transmits good stability.Inner protective layer 4 can prevent that screen 3 is oxidized or be subject to mechanical damage.External protection 5 is by polyethylene (PE; Polyethylene) and carbon black be mixed, there is good cold resistance, also there is good resistance to wear and corrosion resistance simultaneously; after polyethylene and carbon black mix, by the mode of extruder extrusion molding, be coated on the outside of inner protective layer 4.The cold resistance of the cold-resistant waterproof coaxial-cable of the present invention is good, can under the low temperature environment of-40 ℃, use, and corrosion resistance is good, acid and alkali-resistance, and the conductor 1 of cable is outer simultaneously a plurality of protective layers, and good waterproof performance, is not subject to the impact of wet environment, and the requirement of waterproof wiring reduces.
Further, the conductor 1 in the present embodiment is anaerobic electrician copper, and purity is up to 99.99%, and elongation and resistivity properties are good.
Further, the insulating barrier 2 in the present embodiment is made by low density polyethylene (LDPE) (LDPE, Low Density Polyethylene) material, and insulating barrier 2 higher than 95%, guarantees good alignment with the concentricity of conductor 1.
Further, the screen in the present embodiment 3 comprises aluminium foil and proof copper-wire braided net.Aluminium Foil Package overlays on the outside of insulating barrier 2, and proof copper-wire braided net is coated on the outside of aluminium foil.The shielding rate of aluminium foil reaches 100%, and the shielding rate of proof copper-wire braided net reaches 85%, and both play the effect of dual shield protection.
Further, the inner protective layer 4 in the present embodiment is by PVC(Poly Vinyl Chloride, polyvinyl chloride) to expect to make, intensity is high, nonflammable, acid-alkali-corrosive-resisting.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not departing from the scope situation that aim of the present invention and claim protect, also can make a lot of forms, within these all belong to protection of the present invention.
