Abstract
The utility model discloses a copper core cross-linked polyethylene insulated shielding power cable, and belongs to the field of power cables. The copper core cross-linked polyethylene insulated shielding power cable comprises a main cable core formed by stranding and a grounding cable core arranged at the outer side of the main cable core, and further comprises a filling layer and an outer protective layer arranged at the outermost layer, wherein the main cable core comprises a copper conductor and an insulating layer, and the grounding cable core comprises a copper conductor and an insulating layer. The copper core cross-linked polyethylene insulated shielding power cable is characterized in that the outer protective layer and the filling layer are provided with a metal shielding layer therebetween, the metal shielding layer is a copper-clad aluminum magnesium wire, or the metal shielding layer is a copper wire, or the metal shielding layer is s copper strip. By adopting the technical solution disclosed by the utility model, electromagnetism is shielded by the metal shielding layer, thereby enabling the cable cores not to be interfered by the external electromagnetism; electromagnetic energy inside is not easy to leak to the outside; and the good magnetic shielding property enables the copper core cross-linked polyethylene insulated shielding power cable to operate normally in magnetic pipelines.
Description
Technical field
The utility model relates to power cable field, the particularly crosslinked polyetylene insulated shielding power cable of a kind of copper core.
Background technology
Present cross-linked polyethylene insulated cable is widely used, and it is good that it has environmental stress cracking resistance, and good resistance to wear is arranged, anti-various chemical solvent, high temperature resistant, have the advantages such as good electrical performance, but its shielding properties to magnetic is poor, can not use in magnetic pipeline.
In sum, deficiency and defective for existing cross-linked polyethylene insulated cable need the good crosslinked polyetylene insulated shielding power cable of a kind of Magnetic Shielding Effectiveness, especially to solve the above-mentioned problem of mentioning.
The utility model content
The purpose of this utility model is to provide a kind of copper core crosslinked polyetylene insulated shielding power cable, and this power cable has good diamagnetic interference performance.
The technical problem that the utility model solves can realize by the following technical solutions:
The crosslinked polyetylene insulated shielding power cable of copper core, comprise the stranded master core that forms and the ground connection core that is arranged on the described master core outside, also comprise packed layer and be arranged on outermost outer jacket, described master core comprises copper conductor and insulating barrier, described ground connection core comprises copper conductor and insulating barrier, it is characterized in that, be provided with metal screen layer between described outer jacket and packed layer.
Preferably, described metal screen layer is copper coated aluminum magnesium silk.
Preferably, described metal screen layer is copper wire.
Preferably, described metal screen layer is copper strips.
Owing to having adopted above-mentioned technical scheme, metal screen layer shields electromagnetism, make inner core not be subjected to outside electromagnetic interference, and inner electromagnetic energy is not leaked to the external world easily, have good magnetic screen, the utility model is worked in magnetic pipeline.
Description of drawings
Fig. 1 is the structural representation of the crosslinked polyetylene insulated shielding power cable of the utility model copper core.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
shown in Figure 1, the crosslinked polyetylene insulated shielding power cable of copper core comprises the stranded master core that forms and ground connection core, master core comprises copper conductor 1 and crosslinked polyetylene insulated layer 2, the ground connection core comprises copper conductor 3 and crosslinked polyetylene insulated layer 4, be provided with packed layer 5 at master core and ground connection core, increase the compactness of internal structure, the outermost layer of this power cable is coated with crosslinked polyethylene outer jacket 7, guarantee that this power cable is not subjected to extraneous corrosion, the impact of the operational environments such as high temperature, be provided with copper coated aluminum magnesium silk screen 6 between crosslinked polyethylene outer jacket 7 and packed layer 5, play the effect of diamagnetic interference.
Under the operational environment of rated voltage 0.6～1KV, 6 pairs of electromagnetism of copper coated aluminum magnesium silk screen shield, and make inner core not be subjected to outside electromagnetic interference, and inner electromagnetic energy are not leaked to the external world easily, this power cable can be worked, be not subjected to magnetic disturbance.
Copper coated aluminum magnesium silk screen 6 of the present utility model also can be replaced by copper wire or copper strips, plays same shield effectiveness.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
