Abstract
The invention relates to a steel-cored aluminum strand core overhead insulated cable; the inner core of the cable is the steel-cored aluminum strand core; the cable comprises a steel strand and an aluminum strand; the external periphery of the steel strand is wound with a plurality of aluminum strands; the outer side of the steel-core aluminum strand is provided with a conductor screen layer; and an insulating layer is arranged outside the conductor screen layer. The inner core of the cable is the steel-cored aluminum strand core; by adopting the structure, the strength and tensile force of the overhead insulated cable are increased; and the cable is particularly suitable for high-level building groups, tourism development zones and areas with more trees and bundles. The cable has simple structure, lower production cost and good electric conduction property.
Description
Technical field
The present invention relates to a kind of high-altitude power transmission cable, relate in particular to a kind of steel-cored aluminum strand core overhead insulated cable.
Background technology
Before the eighties, China 10kV circuit also adopts bare wire to set up, and along with urban construction and power network development, safety problem is severe day by day, and the dead accident of getting an electric shock takes place again and again.Especially the forest zone is even more important, and the bare wire transmission of electricity is one of reason that causes forest fire.So aerial insulated cable consumption in upgrading urban and rural power grids is very big now.But because bigger in the electric pole span in farming, mountain, forest zone, so conductor tension requires than higher, general duralumin can't meet the requirements, and security incident takes place easily.
Summary of the invention
The present invention provides a kind of steel-cored aluminum strand core overhead insulated cable in order to overcome the above problems, and has increased the pulling force of aerial insulated cable, is specially adapted to high stored building group, and tourism development zone and the many areas of trees clump have increased security and stability.
Technical scheme of the present invention is: a kind of steel-cored aluminum strand core overhead insulated cable, cable inner core are steel-cored aluminum strand core, and it includes steel strand wire and aluminium stranded conductor, in the steel strand wire outside around many aluminium stranded conductors; Be provided with conductor shield in the steel-cored aluminum strand core outside, conductor shield is provided with insulating barrier outward.The also available zinc-coated wire of steel strand wire replaces.
Advantage of the present invention is: inner core of the present invention is a steel-cored aluminum strand core, adopt this structure to increase the intensity and the pulling force of aerial insulated cable, be specially adapted to high stored building group, tourism development zone and the many areas of trees clump, the present invention is simple in structure, production cost is lower, and electric conductivity is better.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is steel strand wire among the figure, the 2nd, and aluminium stranded conductor, the 3rd, conductor shield, the 4th, insulating barrier.
Embodiment
A kind of steel-cored aluminum strand core overhead insulated cable, this cable inner core is a steel-cored aluminum strand core, it includes steel strand wire 1 and aluminium stranded conductor 2, in steel strand wire 1 outside around many aluminium stranded conductors 2; Be provided with conductor shield 3 in the steel-cored aluminum strand core outside, be provided with insulating barrier 4 outside the conductor shield 3, described steel strand wire 1 can also replace with zinc-coated wire.The present invention has increased the intensity and the pulling force of aerial insulated cable, can extensively apply to high stored building group, built on stilts electric line in area and incity, city electric line that tourism development zone and trees clump are many, the present invention is simple in structure, production cost is lower, electric conductivity is better, can widely popularize.
Claims (2)
1. steel-cored aluminum strand core overhead insulated cable, it is characterized in that: the cable inner core is a steel-cored aluminum strand core, and it includes steel strand wire and aluminium stranded conductor, in the steel strand wire outside around many aluminium stranded conductors; Be provided with conductor shield in the steel-cored aluminum strand core outside, conductor shield is provided with insulating barrier outward.
2. a kind of steel-cored aluminum strand core overhead insulated cable according to claim 1 is characterized in that: the also available zinc-coated wire of steel strand wire replaces.
