Abstract

The utility model discloses an alloy conductor overhead cable, which comprises a plurality of alloy conductors. Insulation layers made of weather resistant polyvinyl chloride or polyethylene or cross-linked polyethylene material are extruded outside the alloy conductors. The alloy conductors are mutually stranded to form a cable core. Phosphide steel wire is respectively arranged inside each alloy conductor and a plastic tube is arranged outside each alloy conductor. The inner wall of the plastic tube is attached with a layer of high temperature resistant polyester film tape. A wrapping layer is coated outside the cable core. A filling layer which is made of waterproof paste is arranged between the wrapping layer and the cable core. A foaming armored layer which is made of a plastic foaming polymer material is extruded and molded outside the wrapping layer. A sheath layer is extruded and molded outside the foaming armored layer. According to the alloy conductor overhead cable, as the phosphide steel wire is arranged inside the conductor to form a tensile conductor, the mechanical strength of the cable is improved and at the same time the production cost is reduced; and in addition, as the foaming armored layer which is made of a plastic foaming polymer material is adopted outside the cable core, the mass of the cable is reduced, installation and laying of the cable are convenient and the service life of the cable is prolonged.

Description

A kind of alloy conductor aerial cable
Technical field:
The utility model relates to the cable technology field, relates in particular to a kind of alloy conductor 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.How reducing the conductor cost is the problem that present need solve,
To use almag be that the aerial insulated cable of insulation replaces traditional aluminium stranded conductor and steel reinforced aluminium conductor for reducing the installation laid down cost as conductor, with weatherability polyvinyl chloride, polyethylene and crosslinked polyethylene to proof after deliberation, and the fail safe of raising operation of power networks has great significance.
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 alloy conductor aerial cable, and structural design is novel, lower cost for material, and intensity is high, has satisfied the demand of actual working environment fully.
The technical scheme of the utility model is following:
The alloy conductor aerial cable; It is characterized in that: comprise that several outsides extrusion molding has the mutual stranded formation cable core of alloy conductor of the insulating barrier of weatherability polyvinyl chloride or polyethylene or cross-linking polyethylene materials; Be respectively equipped with the phosphatization steel wire in the described alloy conductor, insulating barrier is provided with plastic tube outward, and the plastic tube inwall is with one deck high temperature resistance polyester film band; Described cable core is wrapped with lapping layer; Be provided with waterproof paste between lapping layer and the cable core and fill the packed layer that constitutes, the outer extrusion molding of lapping layer has the foaming armour of plastic foamed polymeric material, and the outer extrusion moulding of foaming armour has restrictive coating.
Described alloy conductor aerial cable is characterized in that: also be provided with earth connection in the described packed layer.
Described alloy conductor aerial cable is characterized in that: described alloy conductor is the magnadure conductor.
The utility model has the advantages that:
The utility model is provided with the phosphatization steel wire and constitutes the tension conductor in conductor; Also reduced cost when having improved the mechanical strength of cable; Cable core also adopts the foaming armour of plastic foamed polymeric material outward in addition; Reduce the quality of cable, be convenient to install and lay, prolonged the useful life of cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
The alloy conductor aerial cable; Comprise that several outsides extrusion molding has the alloy conductor 1 mutual stranded formation cable core of the insulating barrier 2 of weatherability polyvinyl chloride or polyethylene or cross-linking polyethylene materials, be respectively equipped with phosphatization steel wire 3 in the alloy conductor 1, the insulating barrier 2 outer plastic tubes 4 that are provided with; Plastic tube 4 inwalls are with one deck high temperature resistance polyester film band 5; Cable core is wrapped with lapping layer 6, is provided with waterproof paste between lapping layer 6 and the cable core and fills the packed layer 7 that constitutes, and lapping layer 6 outer extrusion moldings have the foaming armour 8 of plastic foamed polymeric material; Can alleviate the weight of the armour of galvanized steel strip or dead braided steel wire formation; Just alleviated the total weight of aerial cable, protected cable core to interrupt the generation of core phenomenon in long-term built on stilts process effectively, foaming armour 8 outer extrusion moulding have restrictive coating 9.
Also be provided with earth connection 10 in the packed layer 7.
Alloy conductor 1 is the magnadure conductor, compares copper conductor, has effectively reduced the cost of conductor.
