Abstract
The utility model discloses a waterproof anti-ultraviolet environment-friendly cable. The cable comprises multiple conductors. The conduct is formed by twisting multi-strand circular wires into a wire beam and is wrapped in a crosslinked polyethylene insulating layer in order to form an insulating wire core. Conductor filling layers are disposed between the crosslinked polyethylene insulating layers and the multi-strand circular wires and use semi-conductive hydrates. The insulating wire cores are mutually twisted in order to form a cable core. The cable core is wrapped in a composite waterproof layer which is formed by a waterproof tape inner wrapping layer and an aluminum-plastic composite tape outer wrapping layer. The composite waterproof layer is wrapped in a grey polyethylene sheath layer by using extrusion molding technology. The waterproof anti-ultraviolet environment-friendly cable has novel structural design and achieves waterproof performance of the conductors. The aluminum-plastic composite tape prevents water from entering the interior of the cable from radial direction while the waterproof wrapping tape prevents water from entering the interior of the cable from lengthways direction. The outer sheath does not contain carbon black but contains ultraviolet absorber which prevents ultraviolet aging and which has no pollution on environment.
Description
Technical field:
The utility model relates to cable, relates in particular to a kind of antiultraviolet environment-friendly cable that blocks water.
Background technology:
Cable uses in the higher coastal area of direct-burried water level, and rainy season the frequent torrid zone and subtropical zone.Because cable is using and the improper introducing moisture of cable laying operation under this environment for a long time. these denier moisture are under operating electric field of cable and temperature acting in conjunction, the moisture immersion can make the conductor oxidation, and insulation suction back generation water tree and electricity tree, finally cause treeing breakdown.In the rainy frequent torrid zone and subtropical zone,, shortened the useful life of cable greatly simultaneously because the too high ultraviolet ray of temperature is strong excessively.Cable antiultraviolet technology more and more causes people's attention.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of antiultraviolet environment-friendly cable that blocks water, and reasonable in design has block-water performance and ultra-violet radiation resisting and electric trace destructive characteristics, has prolonged the useful life of cable.
The technical solution of the utility model is as follows:
The antiultraviolet environment-friendly cable blocks water, comprise several conductors, it is characterized in that: described several conductors constitute by the stranded bunchy of multiply round conductor, several conductors are coated with crosslinked polyetylene insulated layer outward respectively and constitute insulated wire cores, gap between crosslinked polyetylene insulated layer and the multiply round conductor is provided with conductor filled layer, conductor filled layer adopts the semiconductive hydrate, the insulated wire cores bunchy of joining mutually constitutes cable core, cable core is coated with compound water blocking layer, compound water blocking layer is by lapping layer in the waterstop, the outer lapping layer of aluminium-plastic tape constitutes, and the outer extrusion moulding of compound water blocking layer has grey pe sheath layer.
The described antiultraviolet environment-friendly cable that blocks water is characterized in that: also be provided with the rubber bar that blocks water between described compound water blocking layer and the cable core.
The utility model has the advantages that:
1, is filled with the semiconductive compound that blocks water between the conductor, do not stay any slit, make water lose the passage that in conductor, flows, realize the whole purpose that blocks water fully.
2, block water twining package tape and the packing that blocks water of cable inside have under the situation that moisture invades at cable end, expand rapidly, stop water further vertically deeply, guarantee the electrical insulation properties of cable.
3, aluminium-plastic tape can rise enough to play and prevent that sealing radially enters cable inside.
4, oversheath adopts the grey polyethylene, does not contain carbon black, and infiltrating has ultra-violet absorber, can anti-ultraviolet aging, and anti-electric again trace destroys the requirement of cable.
5, cable does not produce harmful halogen gas, does not produce corrosive gas, and the fever amount is few during burning, and contaminated soil does not play environmental-protection function.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
The antiultraviolet environment-friendly cable blocks water, comprise several conductors 1, several conductors 1 constitute by the stranded bunchy of multiply round conductor, be coated with crosslinked polyetylene insulated layer 2 outside several conductors 1 respectively and constitute insulated wire cores, gap between crosslinked polyetylene insulated layer and the multiply round conductor is provided with conductor filled layer 3, conductor filled layer 3 adopts the semiconductive hydrate, the insulated wire cores bunchy of joining mutually constitutes cable core, cable core is coated with compound water blocking layer 4, compound water blocking layer 4 is by lapping layer 4-1 in the waterstop, the outer lapping layer 4-2 of aluminium-plastic tape constitutes, compound water blocking layer 4 outer extrusion moulding have grey pe sheath layer 5, and grey pe sheath layer 5 contains ultra-violet absorber.
Also be provided with the rubber bar 6 that blocks water between compound water blocking layer 4 and the cable core.
Fill coating conductor technology: conductor is carried out preheating, extrude the semiconductive compound that blocks water then, conductor filled thing is met heat fusing, just is coated on the conductor, and preheat temperature is 120 ~ 150 ℃, extrudes crosslinked polyetylene insulated layer 2 at all wire external layers at last.
Claims (2)
