Abstract
The invention discloses an anti-icing aerial insulated cable, comprising a cable core formed by a conductor and an insulating layer covering the conductor externally, wherein the cable core is externally provided with a heat conduction layer with high hydrophobicity. The anti-icing aerial insulated cables are applied to transmitting electric energy in aerial lines with alternating current voltage being 35kV or below 35kV. The anti-icing aerial insulated cable has the characteristics of good electric property, mechanical property, heat aging resistance, environmental stress resistance and chemical corrosion resistance, simple structure, light weigh, good anti-icing performance, deicing performance and the like; and the ice preventing and deicing effects can be realized on the cable surface in ice and snow and freezing rain weather, thus ensuring the safe transmission running.
Description
Technical field
The invention belongs to the power cable field, specifically is a kind of high hydrophobicity, the anti-freeze aerial insulated cable of high-termal conductivity.
Background technology
The existing power aerial insulated cable is made of conductor and insulating barrier mostly, is used for the electric power long-distance transmissions.The aerial insulated cable of this structure under the weather condition of no ice rain, wind and snow, can both satisfy the requirement of safety transmission of electricity.But in actual motion, this aerial insulated cable is under the situation that meets with strong snowfall, sleet weather, cable surface can form hangs frost, icing and icicle, even form than thickness ice cover on aerial insulated cable surface, strengthen the own wt of aerial insulated cable, caused broken string or shaft tower to fracture circuit interruption, make troubles to people's lives, also bring about great losses to country.Therefore, under ice and snow, sleet weather condition, in time to aerial insulated cable defrost, deicing, prevent that its surface from freezing, and just seems particularly important.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, and a kind of high hydrophobicity, the anti-freeze aerial insulated cable of high-termal conductivity are provided.
The invention discloses a kind of high hydrophobicity, the anti-freeze aerial insulated cable of high-termal conductivity, comprise by conductor, insulating barrier constituting core, described core sprays one deck hydrophobicity high thermal conductivity layer outward, and this hydrophobicity high thermal conductivity layer can prevent effectively that cable surface from freezing.
Among the present invention, preferably, hydrophobicity high thermal conductivity layer thickness is 0.1-0.3mm.
High hydrophobicity of the present invention, the anti-freeze aerial insulated cable of high-termal conductivity, be in a kind of hydrophobicity of common aerial insulated cable surface spraying, high conductivity material, form thin film, characteristics such as height is hydrophobic because this material has, high heat conduction, water and cable surface are without any absorption affinity, can not form freezing, and few part accumulated snow of cable surface and freezingly also can melt because of the cable surface high thermal conductivity layer.Therefore, water, ice and snowflake all can not accumulate at cable surface, thereby avoid or reduced the be pressed down generation of accident of cable or shaft tower, guarantee the normal operation of line powering.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of cable of the present invention.
Embodiment:
As Fig. 1, anti-freeze aerial insulated cable of the present invention constitutes core by conductor 1 and the outer insulating barrier 2 of conductor, and the core outer surface forms hydrophobicity high thermal conductivity layer 3 by a kind of hydrophobicity of spraying, high conductivity material.The present invention is applicable on alternating voltage 35kV and the following overhead transmission line and makes transmission of electric energy.The ability that not only has excellent electric property, mechanical performance, heat aging property, environmental stress resistance and resistance to chemical corrosion, and characteristics such as simple in structure, in light weight have good anti-freeze, deicing performance simultaneously again.Occurring to realize the anti-freeze and deicing of cable surface under ice and snow, the sleet weather condition, ensureing the transmission of electricity safe operation.
The invention provides the thinking and the method for a kind of high hydrophobicity, the anti-freeze aerial insulated cable of high-termal conductivity; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.The all available prior art of each component part not clear and definite in the present embodiment is realized.
Claims (2)
