Description
Technical field
The utility model relates to trolley wire technical fields, and in particular to a kind of novel overhead insulation line.
Background technique
With the rapid development of the national economy, the wire and cable as national economy aorta, dosage and use scope
It is increasing.Insulated aerial cable is a kind of common high-altitude power transmission line, is mainly used in avenue, afforests location, is close
The overhead transmission line of building and the rural area wide geographic area for requiring power supply safety and operational management continuous improvement, are particularly suitable for
The positions such as thickly populated city, small towns and green belt.
But many aerial cables all use steel core as carrying core at present, and the increase of steel core can be improved whole of cable
Pull-off force, but the increase of cable Unit Weight is also resulted in, cable laying pendency is larger.In addition, steel core can also be such that transmission line of electricity produces
Raw magnetic hystersis loss and eddy-current loss, so that line loss greatly increases.
Utility model content
For the above problem, the utility model provides a kind of novel overhead insulation line, the traditional carrying of the insulated electric conductor
Core is replaced into old metal material by steel core, reduces the weight of insulated electric conductor, while increasing it and stretching slightly.
To achieve the goals above, the utility model adopts the following technical solution: a kind of novel overhead insulation line, described
Insulated electric conductor center is provided with carrying core, and several conductor wires are arranged around the carrying core, and are bonded to each other, described to lead
The outside of electric wire is successively coated with wrapping layer, external shielding layer and external sheath layer；The carrying core is non-metallic material, including from interior
To the hollow stem being sequentially distributed outside, the first armor and the second armor, first armor includes that several sections are fan
The unit of shape, several described sections are the outside that fan-shaped unit is stranded in hollow stem, and second armor includes several
A section is circular unit, several described sections are circular unit according to the side opposite with the first armor direction of lay
To the outside for being stranded in the first armor.
Further, the material of the hollow stem, the first armor and the second armor is carbon fiber or glass fibre.
Further, conductive coating is provided on the outside of the hollow stem, the first armor and the second armor.
Further, the conductor wire includes conductor wire core, and is successively coated on flame-retardant layer on the outside of conductor wire core, interior
Insulating layer and internal shield.
Further, the flame-retardant layer is made of mica tape.
Further, the inner insulating layer is crosslinked polyethylene.
Further, the external sheath layer is polyurethane.
The novel overhead insulation line of the utility model, carrying core is made of nonmetallic materials, so that the insulating frame
The axial strength of empty electric wire is higher than traditional steel-cored aluminium strand, and weight only has 1/10th or so of traditional steel core, significantly
The total weight for alleviating overhead transmission line also reduces its volume, therefore its self weight, wind load and ice load all obtain significantly
It reduces, while increasing the tower of shaft tower away from reducing project cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram for carrying core；
In above-mentioned figure: 1- carries core；11- hollow stem；The first armor of 12-；The second armor of 13-；2- conductor wire；3- around
Covering；4- external shielding layer；5- external sheath layer.
