Abstract
The invention discloses a multi-core cable which comprises a first cable core layer stranded by a plurality of cable core conductors. An insulating layer is disposed outside the first cable core layer. A second cable core layer formed by a plurality of cable core conductors is annularly distributed outside the insulating layer. A shielding layer is disposed outside the second cable core layer. The multi-core cable has the advantages that the cable generates no electromagnetic interference to the outside, and the cable is few in process, simple in structure, fast in production, low in cost and high in system safety.
Description
?
Technical field
The invention belongs to power cable technology, specifically a kind of multicore cable.
Background technology
Prior art, for two core power cables, is all to extrude insulation stranding after adopting conductor stranded substantially, then protects the mode of production of jacket.For the occasion that has shielding requirements, mostly adopt the mode of wrapped copper strip shielding or employing proof copper-wire braided, the cable of this kind of structure can play certain shield effectiveness for the electromagnetic interference in certain frequency, but shield effectiveness is just poor under high frequency, to the electromagnetic interference of electric equipment generation around, the occasion high to shielding requirements can not meet.
Summary of the invention
The object of this invention is to provide a kind of multicore cable, cable itself does not produce electromagnetic interference to external world, and it is few that this cable of while has technical process, and product structure is simple, and speed of production is fast, and cost is low, the feature that security of system is high.
Technical scheme of the present invention is as follows:
, including the stranded First Line sandwich layer of several core conductors, First Line sandwich layer is outward insulating barrier, and described insulating barrier outer ring is placed with many core conductors and forms the second core layer, and the second core layer is provided with screen outward.
Cable of the present invention has relative high advantage aspect technical process and cost.Indication 1.8/3kV of the present invention and following fireproof power cable, 35kV and following power cable comprise plain edition and armored type cable, flame retardant type and low-smoke halogen-free flame retardant power cable.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
Embodiment
Referring to accompanying drawing, a kind of multicore cable, includes the stranded First Line sandwich layer 1 of several core conductors 2, and First Line sandwich layer is outward insulating barrier 3, and insulating barrier outer ring is placed with many core conductors 5 formation the second core layer 4, the second core layer and is provided with screen 6 outward.
Claims (1)
1. a multicore cable, includes the stranded First Line sandwich layer of several core conductors, and First Line sandwich layer is insulating barrier outward, it is characterized in that: described insulating barrier outer ring is placed with many core conductors and forms the second core layer, and the second core layer is provided with screen outward.
