Abstract
The utility model relates to an offshore floating type wind power generation cable which comprises a waterproof outer protective layer, a braided reinforcement layer stuck on the inner side of the waterproof outer protective layer, a foam inner lining layer filled in the braided reinforcement layer, a wire core placed in the foam inner lining layer and an insulating layer coating the wire core; the offshore floating type wind power generation cable can lead the cable to float on the water surface through the foam inner lining layer filled in the cable, thereby facilitating the installation, the laying, the movement, the maintenance and other operations of the cable; and the waterproof outer protective layer and the braided reinforcement layer can prevent the infiltration of seawater and enhance the waterproof function.
Description
Technical field
The utility model relates to a kind of cable, especially a kind of extra large floating wind electric power generation cable.
Background technology
The coastal waters wind-driven generator is generally on the sea on distance seashore land 1 to 3km, and actual near the part seashore on land is beach, along with the fluctuation of tidewater, is the shallow sea sometimes, is land sometimes.
The electric power that the coastal waters wind-driven generator sends mainly is transported on the bank transformer by submarine cable now.
But submarine cable exists following problem and shortcoming:
1, submarine cable is inconvenient to install and lay;
2, submarine cable is inconvenient to move and keep in repair;
3, can not merge with wind electric power generation cable and shared, need make joint, have potential safety hazard during immersion work.
So, need a kind of new used for wind power generation cable to address the above problem.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, a kind of convenient working is provided and has the coastal waters wind-driven generator cable of water-proof function.
For achieving the above object, the utility model sea floating wind electric power generation cable can adopt following technical scheme: a kind of extra large floating wind electric power generation cable, this sea floating wind electric power generation cable have the waterproof outer jacket, are affixed on the braiding reinforced layer of waterproof outer jacket inboard, are filled in the interior foaming inner covering of braiding reinforced layer, are positioned over core in the foaming inner covering and the insulating barrier that coats this core.
Compare with background technology, the utility model sea floating wind electric power generation cable is filled with the foaming inner covering by inside can make this cable float on the surface, and has made things convenient for the installation of cable and lays and move and operations such as maintenance; And waterproof outer jacket and braiding reinforced layer can prevent that seawater from infiltrating, and strengthened its water-proof function.
Description of drawings
Accompanying drawing is the generalized section of the utility model sea floating wind electric power generation cable.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these execution modes only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
See also shown in the accompanying drawing, the utility model sea floating wind electric power generation cable 100 can be used in the offshore wind power system, this sea floating wind electric power generation cable 100 have be arranged in outermost with waterproof outer jacket 20, the braiding reinforced layer 30 that is affixed on waterproof outer jacket 20 inboards, the foaming inner covering 40 that is filled in braiding reinforced layer 30 that are used for preventing seawater and infiltrate, be positioned over foam the copper conductor core 50 of inner covering 40 and the insulating barrier 60 that coats this copper conductor core 50.Described copper conductor core 50 is three.
This wherein, the filling of foaming inner covering 40 is in order to increase the external diameter of this sea floating wind electric power generation cable 100, the volume of cable is increased, thereby produce enough buoyancy, and foaming inner covering 40 is owing to adopt the structure of foaming, make and extra large floating wind electric power generation cable 100 can be kept afloat itself very light in weight, and do not sink.And cable float over sea top cable installation and lay and move and maintenance.And the insulating barrier 60 of described coating copper conductor core 50 adopts crosslinked polyethylene (XLPE) material, the advantage of this kind material is to have good electrical insulation properties and lighter proportion, thin thickness, light specific gravity, thus cable weight can be alleviated, help cable to keep afloat.
Described waterproof outer jacket 20 adopts special waterproof plastic sheath, can guarantee that seawater does not immerse the cable internal structure.
Braiding reinforced layer 30, can improve the axial stretching resistance of this sea floating wind electric power generation cable 100 on the one hand, make extra large floating wind electric power generation cable 100 can stand the axial tension that seawer tide produces cable, has resistance effect on the other hand, under the situation of waterproof outer jacket 20 breakages, can stop coastal floating wind electric power generation cable 100 axial dispersions of seawater and development.
In sum, the utility model sea floating wind electric power generation cable 100 can float on the surface, greatly simplified and reduced the operation and maintenance cost of Oversea wind power generation transmission with cable, and waterproof outer jacket 20 that adopts and braiding reinforced layer 30 have improved the waterproof ability and the intensity of cable, make the utility model sea floating wind electric power generation cable 100 be used for can improving after the offshore wind power system operational reliability of offshore wind power system.
