Abstract
The utility model discloses an Mg-Al-Si alloy overhead conducting wire, which comprises a wire core formed by a plurality of mutually-twisted alloy conductors, wherein strengthening cores are respectively arranged in the alloy conductors; and tinned layers are coated outside the alloy conductors. The Mg-Al-Si alloy overhead conducting wire with a reasonable structural design has the advantages that as the strengthening cores formed by twisting carbon fibers to form rope shapes are arranged in the conducting wire and the tinned layers are coated outside the conductors, the conductors of the conducting wires become tensile conductors; and meanwhile, as the Mg-Al-Si alloy conductors are adopted, the creep-resistant performance is improved and the service life of the conducting wire is prolonged.
Description
Technical field:
The utility model relates to the lead technology field, relates in particular to a kind of magnalium silicon alloy aerial condutor.
Background technology:
All over the world, 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 basically.Traditional aluminium stranded conductor and steel reinforced aluminium conductor lay with electric power transfer to installation and cause many inconvenience 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, through changing the inner lattice structure of aluminum metal, improve the performance of aluminium conductor.The tensile strength of al-mg-si conductor reaches 400-450MPa; Be 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 of creep appears in the effect that receives mechanical force for a long time contact resistance increases the risk that causes accident.Therefore be that the aerial condutor of conductor is more suitable for installing in the electric power of length, big span with the al-mg-si material.
In the higher operational environment of this external requirement of strength, the intensity of original lead can not reach the demand of operational environment far away.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of magnalium silicon alloy aerial condutor, and structural design is novel, and intensity is high, has satisfied the demand of actual working environment fully.
The technical scheme of the utility model is following:
Magnalium silicon alloy aerial condutor comprises that several stranded each other alloy conductors constitute 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 magnalium silicon alloy aerial condutor is characterized in that: the rope that described strengthening core adopts carbon fiber to be twisted into.
Described magnalium silicon alloy aerial condutor is characterized in that: described alloy conductor adopts the magnalium silicon alloy.
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 the lead, conductor scribbles tin coating outward; Make the conductor of lead become the tension conductor; Adopt the magnadure conductor simultaneously, being improved of creep-resistant property prolonged the useful life of lead.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Magnalium silicon alloy aerial condutor comprises that several stranded each other alloy conductors 1 constitute 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.
