Abstract
The utility model discloses an improved generation overhead insulated cable, including the conductor, the outside from interior to exterior of conductor sets gradually insulating layer and sheath, be equipped with between conductor and the insulating layer at a distance from the fire -retardant band of oxygen, be equipped with the insulating layer between insulating layer and the sheath, the conductor includes carbon fiber complex core and locates the outside aluminum alloy single line of carbon fiber complex core, and carbon fiber complex core and aluminum alloy single line are the concentric stranding structure. The utility model discloses temperature resistance range promotes greatly, fatigue durability, rub resistance, stable good, electric excellent performance. The conductor adopts carbon fiber complex core for bearing the weight of the sinle silk with duo gen aluminum alloy single line concentric stranding forms, and high and the quality is lighter than ordinary steel core intensity, uses the traditional overhead stranded conductor's of its replacement steel core bearing, had both lightened cable weight, has increased its mechanical properties again to the aluminum alloy single line has high creep resistance, high tensile strength, high percentage elongation, strong, the characteristics such as anti -corrosion performance is good, high pliability of dead weight bearing capacity.
Description
Technical field
The utility model belongs to field of cable technology, more particularly to a kind of aerial insulated cable.
Background technology
, generally using aluminum stranded conductor as conductor, the metal activity of aluminium is stronger, and creep properties is poor for conventional overhead insulated cable.
Therefore, its service life and security are all not so good as people's will.
In addition, aerial insulated cable common at present is during extreme low temperature use, insulation is easily hardened, becomes fragile, being difficult
Use.Especially when mounted, it is a serious problem to insulate easy to crack.Existing aerial insulated cable is to the resistance to of high and low temperature environment
By limited in one's ability, it is impossible to which safety satisfaction is actually needed.
Therefore, the defect for how solving above-mentioned prior art presence becomes the direction of art personnel effort.
Utility model content
The purpose of this utility model is just to provide a kind of modified aerial insulated cable, can be fully solved above-mentioned prior art
Weak point.
The purpose of this utility model is realized by following technical proposals：
A kind of modified aerial insulated cable, including conductor, sets gradually insulating barrier and sheath from the inside to the outside outside conductor,
It is characterized in that：The fire-retardant band of oxygen barrier is provided between the conductor and insulating barrier, is provided with insulating layer, institute between insulating barrier and sheath
Stating conductor includes carbon fiber complex core and the aluminium alloy single line outside carbon fiber complex core, and carbon fiber complex core and aluminium
Alloy single line is concentric stranding structure.
Further, the insulating layer is the temperature insulating material layer that centre is provided with air blanketing.
Further, the jacket surface is provided with multiple projections.
Further, screen layer is equipped with outside the carbon fiber complex core and aluminium alloy single line.
Further, thermal insulation foam is filled between the conductor and the fire-retardant band of oxygen barrier.
Compared with prior art, the beneficial effects of the utility model are：
1. simple structure, reasonable in design, and it is same for carrying core and Duo Gen aluminium alloy single lines that conductor adopts carbon fiber complex core
The heart is stranded to be formed, higher than common steel core intensity and quality is lighter, using the steel core load-bearing which replaces conventional overhead twisted wire, both mitigates
Cable weight, increased its mechanical performance again, and aluminium alloy single line has high creep resistance, high-tensile, high extends
The characteristic such as rate, deadweight bearing capacity strong, Corrosion Protection is excellent, high-flexibility.
2. temperature resistant range is greatly promoted, fatigue durability, rub resistance, good stability, excellent electrical properties.

5.The insulating layer 3 is provided with the temperature insulating material layer of air blanketing for centre.The conductor include high-strength carbon fiber composite core 6 with
And the heat-resisting aluminium alloy single line 7 outside high-strength carbon fiber composite core 6, and high-strength carbon fiber composite core 6 and alumite
Alloy single line 7 is concentric stranding structure.Shielding is equipped with outside the high-strength carbon fiber composite core 6 and heat-resisting aluminium alloy single line 7
Layer 8.
4 surface of the sheath is provided with multiple raised 9, so as to form protective layer on 4 surface of sheath, effectively improves cable entirety
Wearability.
Conductor of the present utility model adopts high-strength carbon fiber composite core 6 for carrying core and Duo Gen heat-resisting aluminium alloy single lines
7 concentric strandings are formed, higher than common steel core intensity and quality is lighter, replace the steel core load-bearing of conventional overhead twisted wire using which, i.e.,
Cable weight is alleviated, its mechanical performance is increased again, and heat-resisting aluminium alloy single line 7 is had high creep resistance, high tensile strong
The characteristic such as degree, high-elongation, deadweight bearing capacity strong, Corrosion Protection is excellent, high-flexibility.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit the utility model, all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
