Abstract
The invention discloses a magnesium-aluminum-silicon alloy overhead cable which comprises a cable core which is composed of multiple mutually-twisted alloy conductors, wherein the interiors of the alloy conductors are respectively provided with a reinforced core, and tin coating layers are coated on the exteriors of the alloy conductors. The magnesium-aluminum-silicon alloy overhead cable provided by the invention has a reasonable design, the interiors of is the conductors are provided with the reinforced cores which are formed by carbon fibers twisted in a rope shape and the tin coating layers are coated on the exteriors of the conductors, so that the conductors of the cable can be changed into tensile conductors; and meanwhile, as magnesium-aluminum alloy conductors are adopted, the creep resistant performance can be improved and the service life of the cable can be prolonged.
Description
Technical field:
The present invention relates to the lead technology field, relate in particular to a kind of Mg-Al-Si alloy overhead conducting wire.
Background technology:
All over the world, big-length, remote electric power transfer all are to adopt aluminium stranded conductor and steel reinforced aluminium conductor as transport vehicle, and China Three Gorges Projects 500KV transmission and distribution network also adopts aluminium stranded conductor and steel reinforced aluminium conductor substantially.Traditional aluminium stranded conductor and steel reinforced aluminium conductor cause many inconvenience for mounting and installation and electric power transfer because there is the deficiency on the performance in the fine aluminium conductor material.
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.The tensile strength of al-mg-si conductor reaches 400-450MPa, 3-4 times of fine aluminium conductor, its excellent creep-resistant property particularly, creep-resistant property has improved 300% 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.Therefore the aerial condutor take the al-mg-si material as conductor is more suitable for installing in the electric power of big-length, large span.
In the higher operational environment of this external requirement of strength, the intensity of original wire can not reach the demand of operational environment far away.
The utility model content:
In order to remedy the deficiencies in the prior art, purpose of the present invention provides a kind of Mg-Al-Si alloy overhead conducting wire, and structural design is novel, and intensity is high, has satisfied the demand of actual working environment fully.
Technical scheme of the present invention is as follows:
Mg-Al-Si alloy overhead conducting wire comprises that several mutual stranded alloy conductors consist of core, and it is characterized in that: be respectively equipped with strengthening core in the described alloy conductor, alloy conductor scribbles tin coating outward.
Described Mg-Al-Si alloy overhead conducting wire is characterized in that: the rope that described strengthening core adopts carbon fiber to be twisted into.
Described Mg-Al-Si alloy overhead conducting wire is characterized in that: described alloy conductor adopts Mg-Al-Si alloy.
Advantage of the present invention is:
Reasonable in design of the present invention is provided with carbon fiber and is twisted into funicular strengthening core in the wire, conductor scribbles tin coating outward, so that the conductor of wire becomes tensile conductors, adopt simultaneously the magnadure conductor, being improved of creep-resistant property prolonged the useful life of wire.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Embodiment:
Mg-Al-Si alloy overhead conducting wire comprises that several mutual stranded alloy conductors 1 consist of core, and alloy conductor 1 center is respectively equipped with strengthening core 2, the alloy conductor 1 outer tin coating 3 that scribbles.
The rope that strengthening core 2 adopts carbon fiber to be twisted into.
Alloy conductor 1 adopts Mg-Al-Si alloy.
Claims (2)
1. a Mg-Al-Si alloy overhead conducting wire comprises that several mutual stranded alloy conductors consist of core, and it is characterized in that: be respectively equipped with strengthening core in the described alloy conductor, alloy conductor scribbles tin coating outward, and described alloy conductor adopts Mg-Al-Si alloy.
2. Mg-Al-Si alloy overhead conducting wire according to claim 1 is characterized in that: the rope that described strengthening core adopts carbon fiber to be twisted into.
