Abstract
The invention discloses a power cable for a wind power system. The power cable is characterized by comprising a plurality of single-line conductors made of a copper, aluminum or aluminum alloy material, wherein the single-line conductors pass through a circular cable conductor (1) formed by extruding in a layered way; an insulating layer (2) is extruded and coated outside the circular cable conductor (1), so that cable cores is formed; after a plurality of cable cores are combined, an isolating layer (3) made of a non-hygroscopic material is coated outside; and a layer of outer jacket (4) is uniformly extruded outside of the isolating layer (3). The power cable has the advantages of high conductivity, low cost, freeness from pollution, corrosion resistance, creep resistance, fatigue resistance, weather resistance, cold resistance, low temperature flexibility, high water resistance, high electric property, high tensile strength, long service life, and the like.
Description
Technical field
The present invention relates to a kind of wind-powered electricity generation transmission system power cable, belong to the wind energy technical field of cables.
Background technology
China's power supply architecture 70% is Coal-fired Thermal Power, and load growth is rapid, and the environmental impact particularly pressure of reducing emission of carbon dioxide is increasing, wind energy is the regenerative resource of cleaning, and china natural resources is abundant, can large-scale development, wind power cost descends year by year, has a extensive future.National Development and Reform Committee clearly proposes the object of planning of Development of Wind Power In China: national installed capacity of wind-driven power reached 1,500 ten thousand kilowatts in 2015; The year two thousand twenty reaches 3,000 ten thousand kilowatts, and wind-powered electricity generation will have certain ratio in power supply architecture, accounts for when the time comes 2～3% of the total 1,000,000,000 kilowatts of capacity of generator installation in the whole nation, 1～1.5% of total electric weight.Wind energy cable is transmitting important effect as one of electrical equipment of wind-powered electricity generation transmission system to wind-powered electricity generation.Country advocates and to build a conservation-minded society, and carries forward vigorously energy savings, the application of the type that economizes on resources product, but conductivity, anticorrosion, creep resistant, the antifatigue of present wind-powered electricity generation cable, can also be further on the performances such as weatherability.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the above-mentioned deficiency of prior art, provide that a kind of high conduction, cost are low, pollution-free, anticorrosion, creep resistant, antifatigue, weatherability, and have cold-resistant, low temperature flexibility, and the wind power system power cable of the characteristics such as good water preventing ability, electric property, tensile strength height and long service life.
The technical solution used in the present invention is as follows:
A kind of wind power system power cable is characterized in that it comprises the single line conductor that many copper, aluminum or aluminum alloy material are made, the round cable conductor that described many single line conductor dbus form after layer by layer extruding; Described round cable conductor outside is extruded with insulating barrier, forms cable core, and the outside is surrounded by the separator that one deck non-absorbent material is made after the combination of multi-cable core, and described separator outside is evenly pushed one deck oversheath again.
Cable core quantity in every electric power is preferably three.
Described insulating layer material adopts high-strength tear-resistant to split silastic material.
Described oversheath adopts the cold-resistant elastomeric material of environment-friendly type or polyurethane material to make.
Beneficial effect of the present invention has:
Owing to adopted single line to press layer by layer as cable conductor, guarantee that the conductor body structure is stable, have the excellent properties such as high conduction, cost are low, pollution-free, anticorrosion, creep resistant, antifatigue.Because insulation has adopted high-strength tear-resistant to split silastic material, so electrical insulation properties is very good, and tear-proof, high mechanical properties, cold-resistant, flexible, flexibility is good, makes the highest long-term work temperature of this cable bring up to 155 ℃, minimum temperature-60 ℃.Oversheath adopts the cold-resistant elastomer of environment-friendly type or TPUE material, makes sheath have higher mechanical performance, and this sheath has flexibility, elasticity, restorability, cold-resistant, weatherability, the performance such as anti-aging.Enforcement by above measure, make this product have high conduction, lightweight, cost is low, pollution-free, anticorrosion, creep resistant, antifatigue, weatherability, and has cold-resistant, low temperature flexibility, and the characteristics such as good water preventing ability, electric property, tensile strength height and long service life, compared with similar products, can prolong 2～3 times useful life, and greatly improved economy and the fail safe of cable.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described:
The present invention is that a kind of high conduction, cost are low, pollution-free, anticorrosion, weatherability, and has cold-resistant, low temperature flexibility, and the wind-powered electricity generation transmission system power cable of the characteristics such as good water preventing ability, electric property, tensile strength height and long service life.
As shown in Figure 1, it comprises the single line conductor that many copper, aluminum or aluminum alloy material are made the present invention, the round cable conductor 1 that described many single line conductor dbus form after layer by layer extruding; Described round cable conductor 1 outside is extruded with insulating barrier 2, forms cable core, and outside indulging is surrounded by the separator 3 that one deck non-absorbent material is made after the combination of multi-cable core, and separator 3 outsides are evenly pushed one deck oversheath 4 again.Generally speaking, the cable core quantity in every power cable is three.
It is stranded that round cable conductor 1 of the present invention can adopt special-shaped many single line conductors that compress to press layer by layer, and conductor structure presses coefficient and is not less than 0.9 for pressing structure.And insulating barrier 3 materials adopt high-strength tear-resistant to split silastic material, and oversheath 4 adopts the cold-resistant elastomeric material of environment-friendly type or polyurethane material to make.
The undeclared part of other that the present invention relates to is same as the prior art.
