Abstract
The utility model relates to arrive a kind of three core overhead insulated cables, including three insulated wire cores and carrying steel core, the conductor of insulated wire cores is that special-shaped copper aluminium monofilament is twisted compacted conductor, conductor is successively outer to extrude semiconductive internal shield, crosslinked polyetylene insulated layer, semiconductives external shielding layer, carrying steel core extrudes carrying steel core sheath, three insulated wire cores with extrude the carrying steel core twisted synthesizing cable after carrying steel core sheath.The utility model reduces the dosage for saving copper aluminium compared with traditional conventional overhead construction of cable and reduces the outer diameter of cable, and increases substantially the service life of cable.
Description
Technical field
The utility model relates to wire and cable fields, and in particular to a kind of tri- core overhead insulated cable of voltage rating 10kv.
Background technique
The rapid development of State Grid's cause, aerial insulated cable product obtain increasingly extensive application, and conductor resistance is
Measure wire and cable product whether He Ge important indicator, the size of cable conductor DC resistance determines current-carrying capacity of cable
Size.Conventional overhead insulated cable is that the requirement for the conductor resistance and conductor pliability for reaching corresponding nominal area does not make to lead again
The real area of body is excessive, its tightening factor maximum can only can reach under the premise of reaching conductor diameter as defined in traditional handicraft
90%.And aerial insulated cable is all made of naked steel strand wires to increase cable bearing strength, and corrosion resistance is not ideal enough, and naked steel twists
Line is 5-10 using average life span, and service life is shorter.
Utility model content
In view of the above-mentioned problems, can effectively reduce the strand of conductor the utility model proposes a kind of three core overhead insulated cables
It closes outer diameter and improves the tightening factor of stranded conductor, and increase substantially the service life of cable.
In order to achieve the above object, using following technical scheme: a kind of three core overhead insulated cables, including three insulated wire cores
With carrying steel core, the conductor of insulated wire cores is that special-shaped copper aluminium monofilament is twisted compacted conductor, and conductor is successively outer to extrude screen in semiconductive
Cover layer, crosslinked polyetylene insulated layer, semiconductives external shielding layer, carrying steel core extrudes carrying steel core sheath, three insulated wire cores with
Carrying steel core twisted synthesizing cable after extruding carrying steel core sheath.
Further, insulated wire cores are less than with the carrying steel core twisted synthesizing cable pitch ratio extruded after carrying steel core sheath
25。
Further, carrying steel core jacket material is weather-proof polyethylene.
Further, carrying steel core sheath extrudes with a thickness of 1.0mm-2.0mm.
The utility model the utility model has the advantages that three core twisted cables and conductor using special-shaped copper aluminium monofilament cable copper and tradition
Aerial cable structure is compared, and the dosage of copper aluminium saves 3%, and insulated wire cores outer diameter reduces 1.43%, and outer diameter reduces 3.1% after stranding.It holds
Load steel core extrudes outer jacket and especially extrudes weather-proof polyethylene sheath, and average life can be improved to 30 years.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
It is as shown in the figure: 1, conductor；2, semiconductive internal shield；3, crosslinked polyetylene insulated layer；4, semiconductives external shielding layer；
5, steel core is carried；6, steel core sheath is carried.
Specific embodiment
Embodiment
It further illustrates with reference to the accompanying drawing, three core overhead insulated cables of one kind, including three insulated wire cores as shown in the figure
With carrying steel core.The conductor (1) of insulated wire cores is that special-shaped copper aluminium monofilament is twisted compacted conductor, and conductor (1) successively partly lead by outer extrude
Electric internal shield (2), crosslinked polyetylene insulated layer (3), semiconductives external shielding layer (4), carrying steel core (5) extrude carrying steel core shield
Layer (6), three insulated wire cores with extrude carrying steel core (5) twisted synthesizing cable after carrying steel core sheath (6).It is implementing process
Are as follows: wire drawing is carried out on common continous way copper and aluminum wiredrawing machine first, draws out special-shaped copper aluminium monofilament；Existed again with special-shaped copper aluminium monofilament
It is twisted on stranding machine, is pressed by drawing-die, form the conductor (1) of cable；It extrudes on three-layer co-extruded cross-linking unit and partly leads
Electric internal shield (2), crosslinked polyetylene insulated layer (3) and semiconductives external shielding layer (4), extrude carrying steel on common extruding machine
The material of core sheath (6), carrying steel core sheath (6) is weather-proof polyethylene, is extruded with a thickness of 1.0mm-2.0mm；Finally at
By 3 insulated wire cores and carrying steel core (5) twisted synthesizing cable on cable machine, lay ratio is no more than 25 times.
Claims (4)
1. a kind of three core overhead insulated cables, which is characterized in that including three insulated wire cores and carrying steel core, insulated wire cores are led
Body (1) is that special-shaped copper aluminium monofilament is twisted compacted conductor, and conductor (1) is successively outer to extrude semiconductive internal shield (2), crosslinked polyethylene
Insulating layer (3), semiconductives external shielding layer (4), carrying steel core (5) extrude carrying steel core sheath (6), three insulated wire cores with extrude
