Abstract

The utility model discloses an aluminum alloy power transmission aerial cable including a wire core formed by twisting a plurality of aluminum alloy conductors with each other. Reinforcing cores are arranged in the aluminum alloy conductors respectively. The aluminum alloy conductors are coated with the nickel-plated layers. An alloy wire braiding layer is arranged outside the wire core. An insulating layer is formed outside the alloy wire braiding layer through extrusion molding. Insulating material of the insulating layer is formed integrally with the wire core and the alloy wire braiding layer. The aluminum alloy power transmission aerial cable provided by the utility model is reasonable in design. The rope-shaped reinforcing cores formed by twisting carbon fibers together are arranged in the conductors. Besides, an integral structure is formed by the alloy wire braiding layer, the wire core and the insulating layer, so that the tensile strength of the aluminum alloy power transmission aerial cable is improved substantially and the service lifetime of the aluminum alloy power transmission aerial cable is prolonged.

Description

A kind of aluminium alloy power transmission aerial cable
Technical field:
The utility model relates to the lead technology field, relates in particular to a kind of aluminium alloy power transmission aerial cable.
Background technology:
Along with World Copper valency one tunnel is high, China many wires and cables industries manufacturer suffers untold misery.A few days ago, the Senior Expert of China's non-ferrous metal industry represents, the aluminium of electric wire is a kind of development trend for copper, has got long long way to go but will reach desirable effect.Expert's sound, not only pointed out the problem that wires and cables industry exists, affirmed also that simultaneously inevitable choice China that aluminium is industry development for copper is the country of a copper shortage of resources, essence copper output capacity only has 40% again, wherein electric equipment products has accounted for copper resource consumption 25%, and the reserves of aluminium are abundant and price is low, do substitute products with aluminium, become the outlet of a lot of industries.
" aluminium alloy aerial cable " by scientific research is developed into has larger application value, can play the purpose of " with aluminium for copper ", greatly saves China's copper resource in short supply and creates huge economic and social benefits.
In the higher operational environment of requirement of strength, the intensity of traditional aluminium stranded conductor and steel reinforced aluminium conductor can not reach the demand of operational environment far away.
The utility model content:
In order to make up the deficiencies in the prior art, the purpose of this utility model provides a kind of aluminium alloy power transmission aerial cable, and structural design is novel, and the electric power that is suitable for big-length, large span is installed, and has satisfied the demand of actual working environment.
The technical solution of the utility model is as follows:
Aluminium alloy power transmission aerial cable, it is characterized in that: comprise that several mutual stranded aluminium alloy conductors consist of core, be respectively equipped with strengthening core in described aluminium alloy conductor, aluminium alloy conductor scribbles nickel coating outward, described core is provided with the B alloy wire braid outward, the outer extrusion moulding of B alloy wire braid has insulating barrier, and the Insulation Material of insulating barrier is integrally formed through extrusion molding and core, B alloy wire braid.
Described aluminium alloy power transmission aerial cable, it is characterized in that: described strengthening core adopts the stranded formation of carbon fiber.
Described aluminium alloy power transmission aerial cable, it is characterized in that: described B alloy wire braid thickness is insulating barrier 1/5 ~ 1/3.
The utility model has the advantages that:
The utility model reasonable in design is provided with carbon fiber and is twisted into funicular strengthening core in wire, in addition, B alloy wire braid, core and insulating barrier form integrative-structure, have greatly improved the tensile strength of cable, have extended the useful life of wire.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Aluminium alloy power transmission aerial cable, comprise that several mutual stranded aluminium alloy conductors 1 consist of core, aluminium alloy conductor 1 adopts the Mg-Al-Si alloy conductor, be respectively equipped with strengthening core 2 in aluminium alloy conductor 1, the outer nickel coating 3 that scribbles of aluminium alloy conductor 1, core is provided with B alloy wire braid 4 outward, and the outer extrusion moulding of B alloy wire braid 4 has insulating barrier 5, and the Insulation Material of insulating barrier 5 is integrally formed through extrusion molding and core, B alloy wire braid 4.
Strengthening core 2 adopts the stranded formation of carbon fiber.
B alloy wire braid 4 thickness are insulating barrier 1/5 ~ 1/3.
As everyone knows, in the fine aluminium fusion process, add suitable magnesium, iron and rare earth element, by changing the lattice structure of aluminum metal inside, improve the performance of aluminium conductor.
Experimental results show that: the tensile strength of al-mg-si conductor reaches 400 ~ 450MPa, 3 ~ 5 times of fine aluminium conductor, its excellent creep-resistant property particularly, creep-resistant property has improved 350% than fine aluminium, thereby has avoided causing that because creep appears in the effect that is subject to for a long time mechanical force contact resistance increases the risk that causes accident.

Claims (3)

1. an aluminium alloy power transmits aerial cable, it is characterized in that: comprise that several mutual stranded aluminium alloy conductors consist of core, be respectively equipped with strengthening core in described aluminium alloy conductor, aluminium alloy conductor scribbles nickel coating outward, described core is provided with the B alloy wire braid outward, the outer extrusion moulding of B alloy wire braid has insulating barrier, and the Insulation Material of insulating barrier is integrally formed through extrusion molding and core, B alloy wire braid.
