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 multiple alloy conductors are wrapped with insulating layers, the interiors of the alloy conductors are respectively provided with a reinforced core, tin coating layers are coated on the exteriors of the alloy conductors and a protective sheath layer is wrapped on the cable core. The magnesium-aluminum-silicon alloy overhead cable provided by the invention has a reasonable design, the interiors of is the conductors 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 cable technology field, relate in particular to a kind of magnesium-aluminum-silicon alloy overhead cable.
Background technology:
Along with further going deep into of upgrading urban and rural power grids, the safety issue that In the distribution system of low voltage electric power is carried just seems particularly outstanding.Be conductor, replace traditional aluminium stranded conductor and steel reinforced aluminium conductor for reducing the mounting and installation cost take weatherability polyvinyl chloride, polyethylene and crosslinked polyethylene as the aerial insulated cable that insulate with aldray, the fail safe that improves operation of power networks has great significance.
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 insulated cable take the al-mg-si material as conductor is more suitable for installing in the electric power of large span, for reducing the land used cost, reducing aerial cable installation Trunk Connector, effectively guarantees the safe operation of cable.
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.
Summary of the invention:
In order to make up the deficiencies in the prior art, purpose of the present invention provides a kind of magnesium-aluminum-silicon alloy overhead cable, 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:
Magnesium-aluminum-silicon alloy overhead cable comprises the mutual stranded formation cable core of alloy conductor of several wrap insulate layers, and it is characterized in that: be respectively equipped with strengthening core in described alloy conductor, alloy conductor scribbles tin coating outward, and described cable core is wrapped with restrictive coating.
Described magnesium-aluminum-silicon alloy overhead cable is characterized in that: the outer ground wire that also is provided with of described cable core.
Described magnesium-aluminum-silicon alloy overhead cable is characterized in that: the rope that described strengthening core adopts carbon fiber to be twisted into.
Described magnesium-aluminum-silicon alloy overhead cable 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 conductor, conductor scribbles tin coating outward, make the conductor of wire become tensile conductors, adopt simultaneously the magnadure conductor, being improved of creep-resistant property extended the useful life of cable.
Description of drawings:
Fig. 1 is structural representation of the present invention.
