Abstract
The utility model discloses a medium-voltage shielding cable which is composed of a cable core, a wrapping tape, an inner sheath, a steel wire layer and an outer sheath. The wrapping tape, the inner sheath, the steel wire layer and the outer sheath are successively wrapped outside the cable core from inside to outside. The cable core is composed of a conductor, a first inner semiconductor shielding layer, an insulating layer, a second inner semiconductor shielding layer and a soft copper layer. The first inner semiconductor shielding layer, the insulating layer, the second inner semiconductor shielding layer and the soft copper layer are successively wrapped outside the conductor from inside to outside. Through adoption of the two inner semiconductor shielding layers and the soft copper layer, the medium-voltage shielding cable exhibits a better shielding effect, helps to prevent the insulating layer against breakdown, helps to prevent electric power transmission from being influenced by external interference, and enables stability of an electrical network to be improved.
Description
Technical field
The utility model relates to a kind of cable, especially a kind of MV shielded cable.
Background technology
Electric wire is widely used in the middle of industrial production and the resident living.It is the carrier that electric power is carried, its performance quality directly have influence on electrical network can stablize transmit electric power, can various power equipment run well.Granted publication number provides a kind of shielded type cable for the patent of CN201655389U, include a plurality of core conductors that are equipped with insulating barrier, one is arranged at the outer lapping layer of described core conductor, one is arranged at the outer copper strip shielding layer and of described lapping layer is arranged at the outer outer jacket of described copper strip shielding layer, wherein, axially be provided with at least one copper cash between described lapping layer and the copper strip shielding layer, the disclosed shielded type cable of this utility model arranges copper cash between its lapping layer and copper strip shielding layer, when the copper strip shielding fault rupture, this copper cash can play the effect that connects the copper strip shielding layer, to avoid the forfeiture of shield effectiveness, guaranteed the normal use of cable, but in its set copper strip shielding layer situation that externally electromagnetic interference is larger in the environment, shield effectiveness is difficult to guarantee, has reduced the effect of cable.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of shielding properties and the good MV shielded cable of result of use.
The technical solution of the utility model is: a kind of MV shielded cable, formed by cable core, band, inner sheath, steel wire floor and oversheath, it is characterized in that: described cable core is coated with band, inner sheath, steel wire floor and oversheath from inside to outside successively, cable core is comprised of conductor, the first interior shield semiconductors layer, insulating barrier, the second interior shield semiconductors layer and soft copper layer, and described conductor is coated with the first interior shield semiconductors layer, insulating barrier, the second interior shield semiconductors layer and soft copper layer from inside to outside successively.
Described band is made by nonwoven fabrics.
The insulating barrier of described inner sheath, oversheath and cable core is made by polyvinyl chloride.
Described conductor is made by the composite material of copper cover aluminum, take copper as main body.
The described first interior shield semiconductors layer and the second interior shield semiconductors layer are made nonmetal screen by polyolefin and Carbon Black Conductive Composite.
The beneficial effects of the utility model are:
1. simple in structure, result of use is good, and conductor layer take copper as main body, is easily processed low cost with the composite material of copper cover aluminum;
2. by two-layer interior shield semiconductors layer and soft copper layer are set, play better shielding action, avoided the breakdown phenomenon of insulating barrier, can avoid external disturbance to affect electric power and carry, improved the stability of electrical network.
Description of drawings
Fig. 1 is the structural representation of a kind of MV shielded cable described in the utility model.
Among the figure, 1-conductor, 2-the first interior shield semiconductors layer, 3-insulating barrier, 4-the second interior shield semiconductors layer, 5-soft copper layer, 6-band, 7-inner sheath, 8-steel wire floor, 9-oversheath, 10-cable core.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, a kind of MV shielded cable is comprised of cable core 10, band 6, inner sheath 7, steel wire floor 8 and oversheath 9, and cable core 10 is coated with band 6, inner sheath 7, steel wire floor 8 and oversheath 9 from inside to outside successively.Cable core 10 is comprised of conductor 1, the first interior shield semiconductors layer 2, insulating barrier 3, the second interior shield semiconductors layer 4 and soft copper layer 5, and conductor 1 is coated with the first interior shield semiconductors layer 2, insulating barrier 3, the second interior shield semiconductors layer 4 and soft copper layer 5 from inside to outside successively.
The utility model is simple in structure, and result of use is good, and conductor layer take copper as main body, is easily processed low cost with the composite material of copper cover aluminum; By two-layer interior shield semiconductors layer and soft copper layer are set, played better shielding action, avoided the breakdown phenomenon of insulating barrier, can avoid external disturbance to affect electric power and carry, improved the stability of electrical network.The utility model shielding properties and result of use are good, can stablize to transmit electric power.
