Abstract
The utility model relates to a concentric five-core electrical cable, which comprises conductors, insulating layers, an inner cushion layer and an outer protective layer, wherein the insulating layer is arranged outside each conductor, the inner cushion layer is arranged outside the four conductors, a concentric conductor layer is arranged outside the inner cushion layer, and the outer protective layer is arranged outside the concentric conductor layer. The concentric conductor layer is made of copper wires or copper strips, and can be formed by the spaced winding of the reversed copper strips to the copper wires. An outer cushion layer can be arranged between the concentric conductor layer and the outer protective layer, and conductors can be provided with four equal cores and can be provided with three big cores and one small core. Compared with the five-core cables in the same kind, the utility model has the advantages of compact structure, round configuration, raw material saving, generating cost reducing, softness improving and easy constructing. When electric power is transmitted, surrounding electrical devices can not be interfered, and the influence of foreign electromagnetic interference to the electrical devices connected to the concentric five-core electrical cable is also eliminated.
Description
One, technical field:
The utility model relates to power cable, is a kind of concentric type 5-core power cable.
Two, background technology:
Do not adopt the concentric type conductor in the structural design of traditional 0.6/1kV power cable product, in the transmission and distribution circuit of three-phase system, still use the plastic insulation power cable of this no concentric type conductor (being unshielded characteristic) in large quantities, brought some problems for engineering design, transmission and distribution network operation, mainly there is following shortcoming: the one,, interference free performance is poor.When containing high order harmonic component in the electric current that cable itself is carried, cable can produce electromagnetic interference to the electronic equipment around it; Otherwise extraneous electromagnetic interference also can be coupled on the cable core, and the various electric devices that join with cable are produced electromagnetic interference.The 2nd,, along the cable that lays in the skyscraper,, under the effect of powerful lightning current galvanomagnetic effect, produce overvoltage unavoidably because of unshielded layer, cause the damage or the puncture of insulating barrier.
Three, summary of the invention:
The utility model provides a kind of concentric type 5-core power cable with shielding and anti-interference effect.
The technical solution of the utility model is achieved like this: a kind of concentric type 5-core power cable, comprise conductor, insulating barrier, inner cushion layer and outer jacket, and insulating barrier is arranged outside every core conductor, outside the four-core conductor, inner cushion layer is arranged, the concentric type conductor layer is arranged outside inner cushion layer, outside concentric type line layer, outer jacket is arranged.
Above-mentioned concentric type conductor layer can be made of copper wire or copper strips.
Above-mentioned concentric type conductor layer can be dredged by reverse copper strips and constitute around copper wire.
Bed course outside between above-mentioned concentric type conductor layer and outer jacket, can having.
Above-mentioned conductor can be fourth class core.
It is three one little greatly that above-mentioned conductor can be.
The utility model has been compared following advantage with five-core cable of the same type: compact conformation, and the profile rounding, conservation reduces manufacturing cost, and its flexibility also can be improved, and is easy to construction; When transmitting electric power, can not disturb electric equipment generation on every side; Also eliminated external electromagnetic interference to being connected the influence of the electric equipment on this concentric type 5-core power cable.
Four, description of drawings:
Accompanying drawing 1 is the existing four cross-sectional structure schematic diagrames of one little watt of shape 5-core power cable greatly;
Accompanying drawing 2 is the existing four cross-sectional structure schematic diagrames of a little 5-core power cable greatly;
Accompanying drawing 3 is the existing three cross-sectional structure schematic diagrames of two little 5-core power cables greatly;
Accompanying drawing 4 is the cross-sectional structure schematic diagram of the utility model embodiment 1;
Accompanying drawing 5 is the cross-sectional structure schematic diagram of the utility model embodiment 2;
Among the figure: 1. conductor, 2. insulating barrier, 3. inner cushion layer, 4. concentric type conductor layer, 5. copper wire, 6. copper strips, 7. outer bed course, 8. outer jacket.
Five, embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete execution mode according to above-mentioned the technical solution of the utility model and actual needs.
Embodiment 1, as shown in Figure 4, this concentric type 5-core power cable comprises conductor 1, insulating barrier 2, inner cushion layer 3 and outer jacket 8, outside every core conductor 1 insulating barrier 2 is arranged, outside four-core is led not, inner cushion layer 3 is arranged, concentric type conductor layer 4 is arranged outside inner cushion layer 3, outside concentric type line layer 4, outer jacket 8 is arranged; Wherein: as shown in Figure 4; above-mentioned concentric type conductor layer 4 can be dredged by reverse copper strips 6 and constitute around copper wire 5; and bed course 7 outside preferably having between concentric type conductor layer 4 and outer jacket 8 and help protecting concentric type conductor layer 4, as shown in Figure 4, conductor 1 can be fourth class core.
As shown in Figure 5, embodiment 2 is with the difference of embodiment 1: the conductor 1 of embodiment 2 is three one little greatly.
Because the distinctive concentric type conductor layer of the utility model structure make it have good shielding and interference free performance, and because of the compact conformation conservation has reduced cost, its flexibility also can be improved, be easy to construction.
