The utility model proposes a kind of self-bearing type photovoltaic cable.
As shown in figure 1, in one embodiment, the self-bearing type photovoltaic cable includes being formed in sheath 10, the sheath 10
First cavity 11 and the second cavity 12, are connected between the first cavity 11 and the second cavity 12 by a small size connecting portion 13, institute
State and be provided with the first cavity 11 in line feeder 14, second cavity 12 provided with least one cable core 15；The cable core 15 includes
The conductor 15A and insulating barrier 15B outside the conductor 15A.
Self-bearing type photovoltaic cable in the present embodiment includes sheath 10, and the sheath 10 is preferably made up of polyethylene (PE),
Obviously it can also be made up of other materials, but comparatively polyethylene service life is longer, and it is more environmentally-friendly, it is advantageous to make
It is made of polythene material.The first cavity 11 and the second cavity 12, the first cavity 11 and the second cavity are formd in sheath 10
12 is separate, is provided with the first cavity 11 in line feeder 14, the present embodiment by taking steel strand wires as an example, in the present embodiment, the first chamber
The section of body 11 is circle, and the steel strand wires of many steel wire formation are arranged in the first cavity 11, wherein, the overall diameter of steel strand wires
The internal diameter of the first cavity 11 should be approximately equal to.In the present embodiment, the overall diameter of steel strand wires is preferably slightly smaller than the first cavity 11
Internal diameter, to retain certain bending and folding space.
Cable core 15 is accommodated in second cavity 12, in general, the quantity of cable core 15 is with two in even number root, the present embodiment
Exemplified by root.The section of the second cavity 12 is circle in the present embodiment, it should be appreciated that section for it is circular when, stress evenly,
Therefore the section of the second cavity 12 is still circle in the present embodiment.It is located to improve strong height and protection in the second cavity 12
Inwall in cable core 15, the present embodiment in the second cavity 12 is provided with a polyester layer 17, and polyester here refers to such as gathering pair
Polyethylene terephthalate, polybutylene terephthalate, the polyester of polyarylate.
In the present embodiment, two cable cores 15 are arranged in the second cavity 12, it should be appreciated that if cable core 15 only has two
Root, can cause to still suffer from substantial amounts of space in the second cavity 12, influence in its stability, the present embodiment further in the second cavity
Gasket for packing 16 is provided with 12, the quantity of gasket for packing 16 is at least one.Gasket for packing in the present embodiment is solid or hollow, is filled out
Structure is filled, for cost-effective and mitigation weight, preferably hollow-core construction.In the present embodiment, the section of the gasket for packing is circle,
Obviously, the shape of gasket for packing can also be somebody's turn to do as regular shapes such as triangle, rectangles or is arranged as required to not as needed
Regular shape.
In some embodiments, the gasket for packing 16 is one, and like this, two cable cores 15 and a gasket for packing 16 are mutual
It is in contact, it is ensured that full of the second cavity 12, it is to avoid the movement of cable core 15.In some other embodiment, set
Two gasket for packings 16, as shown in figure 1, two gasket for packings 16 and two cable cores 15 are staggered, play the fixed cable core 15 of auxiliary
Effect, in the present embodiment, there is provided two gasket for packings 16, although cost is increased slightly, but can be by according to the second chamber
The internal diameter of body 12 rationally sets the diameter of gasket for packing 16 and cable core 15 so that two cable cores 15 are separated, it is possible to reduce two cables
Influencing each other between core 15.For example, when the diameter of cable core 15 is identical with the diameter of gasket for packing 16, the internal diameter of the second cavity 12 is about
For 2.4 times of the external diameter of cable core 15.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,
It is every under design of the present utility model, the equivalent structure transformation made using the utility model specification and accompanying drawing content, or
