Abstract

The utility model relates to a low-voltage aluminum alloy power cable, which consists of a wire core of an aluminum alloy conductor and a cross-linked polyethylene insulator, wherein the aluminum alloy conductor mainly consists of aluminum, ferrum and a rare-earth element; an insulation material adopts a cross-linked polyethylene material; and a cross-linking mode can be silane cross-linking, chemical cross-linking or radiation cross-linking. The low-voltage aluminum alloy power cable is simple in structure and excellent in performance.

Description

A kind of low pressure aluminium alloy electric power cable
Technical field
The utility model relates to a kind of technical field of electric wires and cables, relates in particular to a kind of low pressure aluminium alloy electric power cable.
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 the chlorine element, itself has fire resistance, thereby be the comparatively common a kind of selection of cable insulation and sheath, but pvc sheath itself is defectiveness also, the first is owing to contain halogen, human body and environment all there is harm, particularly when catching fire, thereby be a kind of material of not environmental protection, it two is because the characteristics of molecular structure of polyvinyl chloride, its ageing-resistant performance is not fine, thereby 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, can make the longer service life of cable because use all is pvc material, thereby its useful life also be very limited, the effect that plays is also very limited.It is exactly waste material cost and processing cost that such cable also has a defective, because why existing PVC insulating outer layer will extrude one deck PVC restrictive coating again, is to have the PVC material to have above performance defect, protects so need extrude one deck sheath again.
Summary of the invention
The invention provides a kind of low pressure aluminium alloy electric power cable, both can save cost, but also have longer useful life.
The utility model is by the following technical solutions: a kind of low pressure aluminium alloy electric power cable is characterized in that: this cable is made up of crosslinked polyetylene insulated and aluminium alloy conductor its parcel.
This aluminium alloy conductor is a kind of in stranded conductor, compacted stranded conductor or the special-shaped conductor of solid conductor, compression.Conductivity 〉=the 61%IACS of conductor, tensile strength 〉=90Mpa, elongation at break 〉=10%, the cable minimum bending radius is 7 times of outside diameters of cable.Insulating material adopts crosslinked polyethylene, and poly crosslinking method can be crosslinked with silicane, chemical crosslinking or cross-linking radiation.Have fire resistance in the cross-linking polyethylene materials, fire-retardant rank reaches fire-retardant C level.Wrapped one deck mica tape outside aluminium alloy conductor, between the crosslinked polyetylene insulated layer.
Insulating material adopts crosslinked polyethylene, and poly crosslinking method can be crosslinked with silicane, chemical crosslinking or cross-linking radiation.Crosslinked in the following manner polyethylene insulation has excellent more mechanical and physical performance and electric property, and ageing-resistant performance is better, and can reach 40 years useful life, is far superior to pvc material.Because crosslinked polyetylene insulated have 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 0.5 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, fire-retardant rank reaches fire-retardant C level, makes aluminium alloy electric power cable performance excellent more, and purposes is more extensive.Need satisfy fire-resistant requirement in some occasion, outside conductor wrapped one deck mica tape extrudes one deck insulation again.The mica tape that increases has heat insulation, fire-retardant effect, can make power cable just have certain fire-resistance property, can satisfy fire-retardant C level.
