Abstract
The utility model discloses a wind energy cable which belongs to the technical field of a cable. A cable conductor is formed by the compound twisting of strands of ultra-fine copper wires, a composite nonwoven isolating layer is arranged on the surface of the cable conductor, modified EPR (ethylene propylene rubber) is wrapped on the isolating layer for insulation in an extruding manner, and a CPE (chlorinated polyethylene) jacket is then wrapped on the isolating layer in an extruding manner. With strong flexibility, elasticity, restorability, tensile property and low-temperature enduring performance, the wind energy cable is in complete accordance with the performance requirements of softness and warping enduring performance, and is suitable for wire connection of wind power generating equipment with rated voltage of 450/750V or above. Moreover, being specifically used in domestic and overseas wind power fields, the wind energy cable has good social and economic benefits.
Description
Technical field
The utility model relates to a kind of wind energy cable structure, belongs to the cable new technical field.
Background technology
Along with the situation of global energy anxiety, countries in the world all utilize regenerative resource at active development.According to the characteristics of wind power generation be pollution-free, operating cost is low, the construction period is short etc., wind power generation is a sunshine industry that has development potentiality.From 2006, the development one tunnel of global wind power generation was quickened.Data statistics shows that global wind power generation installed capacity increasing degree in 2006 is that global wind energy installed capacity in 26%, 2007 year increases by 27% again on the basis of last year.2007, the installed capacity of global wind energy accumulative total reached 94GW, increases 22GW on year-on-year basis.Wherein, 2007, the U.S. increased wind power generation installed capacity 5.2GW newly; Spain's adding new capacity is 3.5GW; China is 3.4GW.2007, the U.S. strengthened the dynamics of investment of wind energy development, and investment then surpasses 9,000,000,000 dollars, so the wind power generation ability improved 45%, and U.S.'s wind energy accumulative total installed capacity is up to 16.8GW.Claim that according to U.S. wind energy industrial development commission (AWEA) 2008, the wind energy growth momentum of the U.S. was still powerful, estimate that the wind power generation installed capacity will reach 480kWh (kilowatt hour), promptly account for 1% more than of American Electric Power total supply.In recent years, keep 28% speed increment in the whole world as most important regenerative resource wind-powered electricity generation.Because the wind power generation demand is very vigorous, the wind electric power generation cable market potential is huge, will reach 128000 kilometers in 2010.
Because the environment of wind power generation is abominable, it is long again that blower fan requires service life, and cable constantly rotates with blower fan, needs cable to have softness, warping strength ability also can be born certain pulling force, so the material and the structure of cable had special requirement.
The utility model content
The purpose of this utility model is will solve current wind-powered electricity generation cable to lack soft enough technical barrier, and a kind of softness, warping strength wind energy cable are provided.
Wind energy cable described in the utility model, conductor and wrapped successively separator, insulating barrier and the restrictive coating of conductor outer surface in the middle of comprising, conductor wherein are that the superfine copper wire of multiply twists again and forms.
The diameter of per share copper wire is preferably 0.1mm in the conductor, and with compound nonwoven cloth wrapped isolation, it is ethylene propylene rubber insulated to extrude modification on this separator at conductive surface, extrude chlorinated polyethylene sheath again, though it is this structure is simple, very practical, the product of trial-production is very soft, warping strength.
The utility model is rational in infrastructure simple, and the manufacturing is easy, cost is low, pollution-free.Cable has stronger flexibility, elasticity, restorability, pull resistance, flexible resistance; Construction of cable compactness, rounding, safe in utilization, can satisfy the performance requirement of current wind energy cable softness fully, this product is exclusively used in domestic and international wind energy turbine set, has environmental benefit and economic benefit preferably.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 conductor, 2 separators, 3 insulating barriers, 4 restrictive coatings
Embodiment
As shown in Figure 1, the surperficial wrapped compound nonwoven cloth separator 2 of the conductor 1 that twists again at the superfine copper wire of multiply, the peripheral hardware modification is ethylene propylene rubber insulated 3, extrudes chlorinated polyethylene sheath again.
