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 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.
Summary of the invention:
In order to remedy the deficiency of prior art, the object of the invention 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.
Technical scheme of the present invention 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.
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 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 a structural representation of the present invention.
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.
