Abstract
The utility model discloses a magnesium-aluminum-silicon alloy aerial cable which comprises a cable core formed by mutually twisting a plurality of alloy conductors wrapped with insulation layers, wherein reinforcing cores are respectively arranged in the alloy conductors, the conductors are coated with tin-coated layers and the cable core is wrapped with a sheath layer. The magnesium-aluminum-silicon alloy aerial cable disclosed by the utility model is reasonable in structural design, the rope-like reinforcing cores made of twisted carbon fibers are arranged in the conductors, and the conductors are coated with the tin-coated layers, and thus the conductors of conducting wires become tensile conductors; and simultaneously, the magnesium-aluminum-silicon alloy conductors are adopted, so that the creep resistance is improved and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to the cable technology field, relates in particular to a kind of magnalium silicon alloy aerial cable.
Background technology:
Along with further going deep into of upgrading urban and rural power grids, the safety issue that mesolow distribution system electric power is carried just seems particularly outstanding.Using aldray is that the aerial insulated cable of insulation replaces traditional aluminium stranded conductor and steel reinforced aluminium conductor for reducing laid down cost to be installed as conductor, with weatherability polyvinyl chloride, polyethylene and crosslinked polyethylene, and 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, 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 insulated cable of conductor is more suitable for installing in the electric power of big span with the al-mg-si material,, guarantee the safe operation of cable effectively for reducing the land used cost, reducing aerial cable Trunk Connector is installed.
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 cable, 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 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 the described alloy conductor, alloy conductor scribbles tin coating outward, and described cable core is wrapped with restrictive coating.
Described magnalium silicon alloy aerial cable is characterized in that: the outer ground wire that also is provided with of described cable core.
Described magnalium silicon alloy aerial cable is characterized in that: the rope that described strengthening core adopts carbon fiber to be twisted into.
Described magnalium silicon alloy aerial cable 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 conductor, 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 cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Magnalium silicon alloy aerial cable comprises the alloy conductor 1 mutual stranded formation cable core of several wrap insulate layers 2 being respectively equipped with strengthening core 3 in the alloy conductor 1, and alloy conductor 1 is outer to scribble tin coating 4, and cable core is wrapped with restrictive coating 5.
The outer ground wire 6 that also is provided with of cable core.
The rope that strengthening core 3 adopts carbon fiber to be twisted into.
