Abstract
The invention discloses a multi-strand conductor cable. The multi-strand conductor cable consists of four conductors and six outer wrapping layers, wherein the four conductors comprise an aluminum alloy conductor, a nickel conductor, a silver-plated copper conductor and a tin-plated copper conductor; the six outer wrapping layers sequentially comprise a tin-plated copper strip shielding layer, a silver-plated aluminum strip armor layer, a zinc-plated aluminum strip shielding layer, a butyronitrile insulating layer, a low-smoke zero-halogen polyolefin jacket layer and a silver-plated copper strip shielding layer from inside to outside. The cable is good in shielding effect, excellent in insulating performance, resistant to high pressure, flame-retardant and excellent in tensile property.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of multiply conductor cable.
Background technology
Cable is widely used in every field, relate to people's lives, industrial production every field, so the consumption of cable is huge especially, also can be very high to the requirement of quality, but in every field, the quality purposes of cable is required it is different, as at oil, chemical industry and aviation train field productive power cable, just require that cable has good shielding insulation performance and tensile property, could be durable in use, satisfy the demand.
Summary of the invention
In order to increase the practicality of prior art, the object of this invention is to provide a kind of multiply conductor cable with excellent shielding and tensile property.
The present invention takes following technical scheme to realize: a kind of multiply conductor cable, it is made up of four kinds of conductors and six layers of outer casing, four kinds of conductors are respectively aluminium alloy conductor, nickel conductor, silver-plated copper conductor and tinned copper conductor, six layers of outer casing are followed successively by tin-coated copper strip screen from inside to outside, silver-plated aluminium strip armour, zinc-plated aluminium strip screen, butyronitrile insulating barrier, low-smoke halogen-free polyolefin restrictive coating and silver-plated steel band screen, described aluminium alloy conductor is 37 strands, the stranded tin-coated copper strip screen that is extruded in is inner, described nickel conductor is 12 strands and is evenly extruded in silver-plated aluminium strip armour inside, described silver-plated copper conductor is 8 strands, evenly be extruded between zinc-plated aluminium strip screen and butyronitrile insulating barrier, described tinned copper conductor is 8 strands, evenly be extruded between butyronitrile insulating barrier and low-smoke halogen-free polyolefin restrictive coating.
The present invention has following beneficial effect in sum: this cable shield is effective, and insulation property are excellent, high pressure resistant, fire-retardant, and tensile property is superior.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, aluminium alloy conductor; 2, tin-coated copper strip screen; 3, silver-plated aluminium strip armour; 4, zinc-plated aluminium strip screen; 5, butyronitrile insulating barrier; 6, low-smoke halogen-free polyolefin restrictive coating; 7, silver-plated steel band screen; 8, nickel conductor; 9, silver-plated copper conductor; 10, tinned copper conductor.
Embodiment
As shown in Figure 1, a kind of multiply conductor cable, it is made up of four kinds of conductors and six layers of outer casing, four kinds of conductors are respectively aluminium alloy conductor 1, nickel conductor 8, silver-plated copper conductor 9 and tinned copper conductor 10, six layers of outer casing are followed successively by tin-coated copper strip screen 2 from inside to outside, silver-plated aluminium strip armour 3, zinc-plated aluminium strip screen 4, butyronitrile insulating barrier 5, low-smoke halogen-free polyolefin restrictive coating 6 and silver-plated steel band screen 7, described aluminium alloy conductor 1 is 37 strands, the stranded tin-coated copper strip screen 2 that is extruded in is inner, described nickel conductor 8 is 12 strands and is evenly extruded in silver-plated aluminium strip armour 3 inside, described silver-plated copper conductor 9 is 8 strands, evenly be extruded between zinc-plated aluminium strip screen 4 and butyronitrile insulating barrier 5, described tinned copper conductor 10 is 8 strands, evenly be extruded between butyronitrile insulating barrier 5 and low-smoke halogen-free polyolefin restrictive coating 6.
The shielding inhibition index of this cable is less than 0.7; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.
Further, often kind of conductors cross diameter length is 1.5 ㎜; Described silver-plated steel band screen 7 thickness is 2.5 ㎜.
The above is the embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
