Abstract
The utility model relates to a five-core power cable comprising a cable core, a non-woven fabric layer covered on the outer surface of the cable core, an isolated layer covered on the outer surface of the non-woven fabric layer, a steel-tape armouring covered on the outer surface of the isolated layer, and a protective sleeve covered on the outer surface of the steel-tape armouring. The cable is characterized in that the cable core comprises five conductor cores which are of sector structure and insulating layers respectively covered on the outer surface of each conductor core, and the five conductor cores covered by the insulating layers are twisted into the cable core with the cross section being round. The cable has the following advantages that as the fillers arranged among the conductor cores in the prior art are omitted, the external diameter of the cross section of the cable is reduced, thus saving production material, reducing cost and increasing the roundness of the cable.
Description
Technical field
The utility model belongs to the power cable technical field, and particularly relating to a kind of sectional area is 185mm
2The 0.6/1KV 5-core power cable of 300mm.
Background technology
At present, along with the continuous development of China's economic construction and improving constantly of people's living standard, power cable is widely used in the industries such as metallurgy, track traffic, petrochemical industry and architectural engineering.The basic structure of power cable comprises cable core, coats the separator of cable core, the steel-tape armouring that coats separator and the sheath of coated steel band armouring, wherein cable core includes several round conductor cores, each conductor thread core is coated with insulating barrier outward respectively, be coated with between the conductor thread core of insulating barrier and be provided with filler, to increase the roundness of whole cable.
Existing sectional area is 185mm
2-300mm
2The cable core of 0.61KV 5-core power cable form by 5 identical round conductor cores, space between the conductor thread core is bigger, need fill with a large amount of fillers, influences the roundness of cable, increase the external diameter of the cross-section of cable, thereby increased the production cost of cable.The increase of the outside diameter of cable increases the volume and weight of cable hank, is inconvenient to transport; In addition, the increase of the outside diameter of cable also can bring difficulty to construction, increases engineering cost.
Summary of the invention
The utility model provides a kind of roundness height for solving the technical problem that exists in the known technology, can reduce production costs and the 0.6/1KV 5-core power cable of construction cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of 5-core power cable, comprise cable core, be coated on the nonwoven layer on the cable core outer surface, be coated on separator on the nonwoven layer outer surface, be coated on the steel-tape armouring on the separator outer surface and be coated on sheath on the steel-tape armouring outer surface, it is characterized in that: described cable core comprises the conductor thread core of 5 sector structures and is coated on insulating barrier on each conductor thread core outer surface respectively, and 5 conductor thread cores that are coated with insulating barrier are twisted into the cross section and are circular cable core.
The utility model can also adopt following technical scheme:
Identical and the central angle number of degrees in the cross section of described 5 sector conductor cores are 71.5 degree.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, it is the conductor thread core that cable core comprises the sector structure that 5 cross sections are identical, and each conductor thread core is coated with insulating barrier outward respectively, circular configuration is formed in the cross section of described 5 conductor thread cores and the cross section of insulating barrier, removed the filler that is arranged in the prior art between the conductor thread core from, reduced the external diameter of the cross-section of cable, thereby saved the production material, increase the roundness of cable, effectively reduced the production cost of cable.The reducing of the outside diameter of cable makes the volume and weight of cable hank reduce, convenient transportation.Can reduce difficulty of construction by reducing the outside diameter of cable, thereby reduce engineering cost.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of 5-core power cable, comprise cable core 1, described cable core 1 is made up of 5 conductor thread core 1-1 and insulating barrier 1-2, conductor thread core 1-1 is the identical sector structure in cross section, each conductor thread core 1-1 is coated with insulating barrier 1-2 outward respectively, conductor thread core 1-1 and insulating barrier 1-2 are twisted into the cross section and are circular cable core 1, cable core 1 is coated with nonwoven layer 2, the nonwoven layer 2 outer separators 3 that coat, separator 3 is coated with steel-tape armouring 4, and steel-tape armouring 4 is coated with sheath 5, and steel-tape armouring 4 and sheath 5 can prevent effectively that external force from causing damage to cable.Described conductor thread core 1-1 is sector structures of 71.5 degree for the central angle number of degrees.
Embodiment:
The 5-core power cable of 0.6/1KV as shown in Figure 1, its structure from inside to outside is followed successively by: be coated with the stranded cable core that forms 1 of conductor thread core 1-1 of insulating barrier 1-2, the nonwoven layer 2 that is used to tighten cable core 1, separator 3, the steel-tape armouring 4 that prevents the damage cable and sheath 5 respectively by 5.The utility model is applicable to that area of section is 185mm
2-300mm
2The 0.6/1KV 5-core power cable, in the present embodiment, the area of the cross-section of cable is 240mm
2Because the utility model has been eliminated the slit between the conductor thread core 1-1 in the prior art, has removed filler from, thereby has reduced the cross section external diameter of lead, has saved material, effectively reduces the production cost and the construction cost of cable.
