Abstract

The utility model relates to a low voltage single core aluminium alloy power cable, comprising a rare earth aluminium alloy conductor and a crosslinking polyethylene insulating layer, wherein the aluminium alloy conductor mainly comprises aluminium, iron and rare earth elements, the insulating layer is prepared by crosslinking polyethylene material, and the crosslinking mode can be silane crosslinking, chemical crosslinking or irradiation crosslinking. The cable is simple in structure and excellent in performance.

Description

The single core aluminium alloy of a kind of low pressure electric power cable
Technical field
The utility model provides the single core aluminium alloy of a kind of low pressure electric power cable, and it belongs to technical field of electric wires and cables.
Background technology
Domestic lv power cable is substantially based on the copper core, and the comparatively traditional frame mode of single-core cable is from inside to outside: copper core conductor, polyvinyl chloride insulation, twining package tape, pvc sheath.Though copper has very excellent characteristic as cable conductor, is to use the cost of copper cable too high.Polyvinyl chloride has very long history as insulating material and sheath, because polyvinyl chloride contains chlorine, itself has fire resistance, thereby be the comparatively common a kind of selection of cable insulation and sheath, but also defectiveness of pvc sheath itself, the first is owing to contain halogen, human body and environment all there is harm, when catching fire, be a kind of material of not environmental protection particularly, do not meet environmental requirement; It two is because the characteristics of molecular structure of polyvinyl chloride, and its ageing-resistant performance is not fine, thus the useful life of polyvinyl chloride cable generally be not very long, generally be according to the design in 30 years.Though the sheath material of cable outside has the certain protection effect to cable because use all is pvc material, thereby its useful life also be very limited, the effect that plays is also very limited.
Summary of the invention
The utility model provides the single core aluminium alloy of a kind of low pressure electric power cable, both can save cost, but also have longer useful life.
The utility model is by the following technical solutions: the single core aluminium alloy of a kind of low pressure electric power cable, this cable is made up of rare earth aluminium alloy conductor and crosslinked polyetylene insulated layer.
Between described rare earth aluminium alloy conductor and crosslinked polyetylene insulated layer, also be provided with the mica belt.
Described rare earth aluminium alloy conductor is any in solid conductor, compression stranded conductor, the compacted stranded conductor.
The material of described rare earth aluminium alloy conductor mainly is made up of elements such as aluminium, iron and rare earths.This conductor material also comprises elements such as micro-magnesium, copper, zinc, silicon, calcium, vanadium, titanium, chromium, manganese.By the aluminium alloy conductor core of this made, the conductivity 〉=61%IACS of conductor, tensile strength 〉=90Mpa, elongation at break 〉=10%, the cable minimum bending radius is 7 times of outside diameters of cable.
Described crosslinked polyetylene insulated layer material adopts crosslinked polyethylene, and poly crosslinking method can be crosslinked with silicane, chemical crosslinking or cross-linking radiation.By having more excellent mechanical and physical performance and electric property with the crosslinked polyethylene layer of upper type, and ageing-resistant performance is better, and can reach 40 years useful life, is far superior to pvc material.Because crosslinked polyetylene insulated layer has characteristics such as excellent weather-resistant property and environmental corrosion resisting, also significantly be better than polyvinyl chloride useful life, thereby construction of cable design is simpler, twining package tape and pvc sheath layer be can not need, but thereby the processing and the material cost of twining package tape and sheath saved.
Aluminium alloy cable sectional area increases by 1.5 times than copper, just can arrive the electric conductivity standard of copper, can reach the same result of use of copper cable, and the copper conductor cost accounts for the about 70% of copper cable total cost, thereby use aluminium alloy conductor core can be saved many costs.
In order to make cable have flame retardant effect, can in cross-linking polyethylene materials, add fire retardant, to improve the fire resistance of cable, make aluminium alloy electric power cable performance excellent more, purposes is more extensive.In order to increase the fire-resistance property of cable, can be between conductor thread core and insulating barrier wrapped one deck mica tape.
Beneficial effect:
The single core aluminium alloy of the low pressure that the utility model provides electric power cable is an insulating barrier owing to having adopted crosslinked polyethylene, the original used pvc material that compares has better mechanical and physical performance and electric property, and ageing-resistant performance is also better, and can reach 40 years useful life.
And, operation and production cost have been saved because the existence of crosslinked polyetylene insulated layer can not need twining package tape and pvc sheath layer.
What use is the production cost that the rare earth aluminium alloy conductor thread core effectively reduces than copper conductor core.
