Description

Aluminum alloy core photovoltaic cable

Technical Field

The utility model relates to the technical field of cables, especially, relate to an aluminum alloy core photovoltaic cable.

Background

Cables are made of one or more mutually insulated conductors and an outer insulating sheath that carries power or information from one point to another. General cable is as leading core material by the copper core, but the price is more expensive, through adopting the aluminum alloy to replace the copper material, is favorable to reduce cost, but because current aluminum alloy core photovoltaic cable, when abandonment, because the surface of cable has thick outsourcing insulating protection layer, leads to being not convenient for to retrieve the reuse to inside conductor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the cable has thick outer packing insulation protection layer on the surface, which leads to the inconvenience of recycling the inner conductor, and provides an aluminum alloy core photovoltaic cable.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an aluminum alloy core photovoltaic cable, includes the protective layer, the parcel has a plurality of first insulation layers in the protective layer, and is a plurality of all the parcel has a plurality of aluminum alloy to lead the core in the first insulation layer, protective layer one side fixedly connected with connecting portion, connecting portion pass through fixed establishment with the opposite side of protective layer is connected.

Preferably, the fixing mechanism comprises a screw and a mounting hole, the mounting hole is formed in the connecting portion, a threaded hole is formed in the protective layer, and the screw penetrates through the mounting hole and is in threaded connection with the threaded hole.

Preferably, the screw is made of a plastic material.

Preferably, a filler is filled between the plurality of first insulating layers and the protective layer.

Preferably, the protective layer comprises a wear-resistant layer, an elastic layer and a second insulating layer, the elastic layer is bonded on the inner surface of the wear-resistant layer, and the second insulating layer is bonded on the inner surface of the elastic layer.

Preferably, the thickness ratio of the wear-resistant layer to the elastic layer to the second insulating layer is 1.

Preferably, the wear-resistant layer is made of a nitrile rubber material.

The utility model provides an aluminum alloy core photovoltaic cable, beneficial effect lies in: through fixed establishment, fix the protective layer at the surface on first insulation layer, relieve fixed establishment's fixed to the protective layer simultaneously to peel off the protective layer, thereby use the aluminum alloy guide core of first insulation layer parcel as connecting wire, so that retrieve old and useless short cable.

In the figure: the anti-abrasion device comprises a protective layer 1, a connecting portion 2, a filler 3, a first insulating layer 4, an aluminum alloy conducting core 5, a screw 6, a mounting hole 7, an abrasion-resistant layer 8, an elastic layer 9 and a second insulating layer 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-3, an aluminum alloy core photovoltaic cable, including protective layer 1, the parcel has a plurality of first insulation layers 4 in the protective layer 1, first insulation layer 4 is made for polyvinyl chloride, all the parcel has a plurality of aluminum alloy to lead core 5 in a plurality of first insulation layers 4, 1 one side fixedly connected with connecting portion 2 of protective layer, connecting portion 2 is connected with the opposite side of protective layer 1 through fixed establishment, fix protective layer 1 at the surface on first insulation layer 4, release fixed establishment's the fixed of protective layer 1 simultaneously, so that peel off protective layer 1, thereby lead core 5 with the aluminum alloy that 4 parcels on the first insulation layer to use as connecting wire, so that retrieve old and useless short cable.

The fixing mechanism comprises a screw 6 and a mounting hole 7, the mounting hole 7 is formed in the connecting portion 2, a threaded hole is formed in the protective layer 1, the screw 6 penetrates through the mounting hole 7 and is in threaded connection with the threaded hole, the fixing of the two sides of the protective layer 1 is released through loosening the screw 6, and the protective layer 1 is peeled off.

The screw 6 is made of plastic materials, and the plastic materials are adopted, so that the safety is improved, and the condition that metal materials are adopted to conduct electricity is prevented.

The filler 3 is filled between the first insulating layers 4 and the protection layer 1, and the filler 3 is polypropylene.

Example 2

In embodiment 1, although the cable plays a role in protecting the cable core inside by using the protective layer 1, when the cable is dragged and laid with the ground, the protective layer 1 is easily worn, referring to fig. 4, as another preferred embodiment of the present invention, on the basis of embodiment 1, the protective layer 1 includes a wear-resistant layer 8, an elastic layer 9, and a second insulating layer 10, the elastic layer 9 is bonded on the inner surface of the wear-resistant layer 8, the second insulating layer 10 is bonded on the inner surface of the elastic layer 9, the wear-resistant layer 8 is made of a nitrile rubber material, and the thickness ratio of the wear-resistant layer 8, the elastic layer 9, and the second insulating layer 10 is 1.
