Description
Technical Field
The utility model relates to a power cable field specifically is an aluminum alloy aerial [ insulated ] cable.
Background
In medium and low voltage overhead transmission lines, aluminum alloy overhead cables occupy an important position, but aluminum is a reactive metal and is easy to react with substances such as oxygen in the air, and the normal operation of power transmission work can be influenced. And with the continuous development of national industrialization, corrosive substances contained in the air are more and more. In addition, the aluminum alloy overhead cable has the problem of poor heat resistance, and a large amount of heat is easily generated in the power transmission process, so that the loss is increased, and the use is influenced.
Disclosure of Invention
An object of the utility model is to overcome not enough among the prior art, provide an aluminum alloy aerial [ insulated ] cable, this kind of cable has waterproof anticorrosion's effect to can effectively improve the heat resistance of cable.
For solving the prior art problem, the utility model discloses an aluminum alloy aerial [ insulated ] cable, including the wire core, the wire core includes that a plurality of centers on together, sets up the glass fiber median between the adjacent wire core, makes two adjacent wire cores not directly take place the contact, sets up fixed band in the glass fiber median outside, it has the fire retardant to fill between fixed band and the glass fiber median, is provided with the water barrier in the outside of fixed band, the water barrier intussuseption is filled with water proof material, is provided with the insulating layer in the outside of water barrier.
Preferably, the water-resisting material filled in the water-resisting layer is expanded water-resisting powder.
Preferably, the glass fiber isolation tapes are interleaved between the wire cores.
Preferably, the glass fiber isolation belts are connected end to end and are of a closed structure.
Preferably, the glass fiber isolation belt is made of glass fibers.
The beneficial effects of the utility model reside in that: the glass fiber isolation belt is arranged between the two adjacent wire cores in an inserting mode, so that the two adjacent wire cores are separated, the wire cores are prevented from being gathered together, a large amount of heat is prevented from being accumulated, and the service life and the service performance of a product are prevented from being influenced; a flame retardant is filled between the fixed wrapping tape and the glass fiber isolation tape, so that the flame retardant property of the cable is improved; the waterproof layer is arranged on the outer side of the fixed wrapping tape, and the expansion type waterproof powder is filled in the waterproof layer, so that the waterproof powder can quickly touch the original volume which is several times that of the original volume even if water enters, a water path is blocked, and water drops are prevented from entering; the insulating layer is arranged on the outer side of the water-resisting layer, so that the insulating effect and the protecting effect are achieved.

Reference numerals:
1. a wire core; 2. a fiberglass spacer tape; 3. fixing the wrapping tape; 4. a water barrier layer; 5. an insulating layer.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only intended to illustrate the structure of the present invention more clearly.
The utility model provides an aluminum alloy aerial [ insulated ] cable, includes wire core 1, wire core 1 includes that a plurality of centers on together, sets up glass fiber median 2 between adjacent wire core 1, makes two adjacent wire cores 1 directly not take place the contact, sets up fixed band 3 in the 2 outsides of glass fiber median, it has the fire retardant to fill between fixed band 3 and the glass fiber median 2, is provided with water barrier 4 in the outside of fixed band 3, water barrier 4 intussuseption is filled with water proof material, is provided with insulating layer 5 in water barrier 4's the outside.
The water-resisting material filled in the water-resisting layer 4 is expansion type water-resisting powder.
The glass fiber isolation belts 2 are inserted between the wire cores 1 in a staggered mode, the glass fiber isolation belts 2 are connected end to end and are of a closed structure, and the glass fiber isolation belts 2 are made of glass fibers.
The beneficial effects of the utility model reside in that: the glass fiber isolation belt 2 is arranged to be inserted between the two adjacent wire cores 1, so that the two adjacent wire cores 1 are separated, and the wire cores 1 are prevented from being gathered together to cause a large amount of heat accumulation to influence the service life and the service performance of a product; a flame retardant is filled between the fixed wrapping tape 3 and the glass fiber isolation tape 2, so that the flame retardant property of the cable is improved; the waterproof layer 4 is arranged on the outer side of the fixed wrapping tape 3, and the waterproof layer 4 is filled with expansion type waterproof powder, so that even if water enters, the waterproof powder can quickly touch the original volume which is multiple times of the original volume, a water path is blocked, and water drops are prevented from entering; an insulating layer 5 is arranged on the outer side of the water-resisting layer 4, so that the insulating function and the protection function are achieved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
