Technical field
The utility model relates to a kind of cables, and in particular to a kind of fluid type anti-blown sand swing aerial cable.
Background technique
The large-scale popularization and use of aerial cable in the power system, aerial is always the weight of electric system with power cable
Component part is wanted, therefore, for aerial with cable high wind area throughout the year, it is biggish existing aerial cable amplitude of fluctuation often occurs
As there are some potential safety problemss for the service life of transmission and product for electric power.
Aerial cable, which has, to be set up convenience, small investment, transmits that capacitance is big, radiating condition is good, easy to maintain etc. a series of
Advantage is widely applied to electric system, in engineering project.In recent years, with the recovery of global economy and booming, product
Demand it is increasing.And traditional aerial cable structural form generally operates in high wind area, cable flexing width throughout the year
Degree is very big, affects the quality and usage safety performance of product, and then influence the transmission of electric energy.In this case, throughout the year
A kind of high fluid type anti-blown sand of wind area market in urgent need swings aerial cable, to meet the requirement in market and user.But
It is that traditional aerial cable structural form generally operates in high wind area throughout the year, biggish stretching is caused to product.Cable pendulum
Dynamic amplitude is very big, and product is in contact with the trees of surrounding or other barriers, reduces the service life of insulating layer.Affect production
The quality and usage safety performance of product, and then influence the transmission of electric energy.
Utility model content
Utility model aims to solve the above-mentioned prior arts there are cable flexing amplitude is very big, product and surrounding
Trees or other barriers are in contact, and reduce the service life of insulating layer.Affect the quality and safety in utilization of product
Can, and then the problem of the transmission of influence electric energy, a kind of fluid type anti-blown sand swing aerial cable is provided.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of fluid type anti-blown sand swings aerial electricity
Cable, including carrying conductor, electrical conductor, inner insulating layer, flame resistant filler layer and external insulation extrusion packing layer, the carrying conductor and
The electrical conductor is parallel, and flame resistant filler layer is enclosed on the outside of the electrical conductor, is enclosed on the outside of flame resistant filler layer interior
Insulating layer, the inner insulating layer and carrying conductor are wrapped in external insulation extrusion packing layer, the area of the carrying conductor
At least one third of electrical conductor area of section.The application in order to meet in product operation to the needs of tensile strength and
It is laid in and outdoor shaft tower and uses in the working environment by sun light direct beam for a long time for a long time under own wt: individually
The design of cleanliness structure, double insulating Designs, dual anti-ultraviolet light design, make it have excellent tensile strength, wind resistance power is waved and
Anti-ultraviolet function.It is especially extruded in the design of the structure in external insulation with the galvanized strand wires of insulated single wire parallel construction, makes
Product has the single-core cable pull-off force of high tensile strength: greater than copper core or aluminium core 2 times or more.Once encountering strong wind, sand and dust
Sudden and violent weather, product can significantly be swung in air, the stretching without will cause conductor, insulating layer, be realized in product
It can be with the raising in service life.The area of galvanized strand wires is the one third of main line core section.
Preferably, the diameter of the carrying conductor is less than the diameter of the electrical conductor, fluid type anti-blown sand swinging frame
The section of empty cable is in fluid shape.The fluid shape of similar water droplet is presented in the section that fluid type anti-blown sand swings aerial cable.
Preferably, carrying conductor is twisted by 7 galvanized strand wires.
Preferably, the external insulation extrusion packing layer is external insulation polyvinyl chloride overhead insulating layer.
Preferably, the inner insulating layer is the crosslinked polyetylene insulated layer of antiultraviolet.
The substantial effect of the utility model is: fluid type anti-blown sand swings the exploitation of aerial cable, is made according to product
With the particularity of environment, product appearance uses airflow design, effectively reduces the resistance to wind, reduce product and running
Rocking tendency in journey.In addition, product effectively increases the insulation performance and service life of product using double insulating Designs.
