Abstract
The invention discloses a multi-strand conductor armored shielding cable, consisting of three kinds of conductors and six outer wrapping layers. The three kinds of conductors respectively are silver-plated annealed aluminum conductors, tin-plated annealed nickel conductors and silver-plated annealed copper conductors; the six outer wrapping layers sequentially include a silver-plated annealed nickel strip shielding layer, a silver-plated aluminum strip armor layer, a zinc-plated aluminum strip shielding layer, a crosslinking ethylene propylene insulating layer, a low smoke zero halogen polyolefin sheath layer and a zinc-plated annealed aluminum strip shielding layer from inside to outside; 31 silver-plated annealed aluminum conductors are provided, 24 tin-plated annealed nickel conductors are provided, and eight silver-plated annealed copper conductors are provided. The cable is good in shielding effect, good in conductive performance, high pressure resistant, flame retardant, high temperature resistant, excellent in tensile performance, and applicable to fields of petrochemical industry and the like.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of multiply conductor sheathed shielded 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 and a kind ofly have excellent shield effectiveness, electric conductivity is excellent, high pressure resistant, fire-retardant, and the multiply conductor sheathed shielded cable that tensile property is superior.
The present invention takes following technical scheme to realize: a kind of multiply conductor sheathed shielded cable, it is made up of three kinds of conductors and six layers of outer casing, three kinds of conductors are respectively silver-plated annealed aluminium conductor, zinc-plated annealing nickel conductor and silver-plated annealed copper conductor, six layers of outer casing are followed successively by silver-plated annealing nickel strap screen from inside to outside, silver-plated aluminium strip armour, zinc-plated aluminium strip screen, crosslinked second propylene insulating barrier, low-smoke halogen-free polyolefin restrictive coating and zinc-plated annealing aluminium strip screen, described silver-plated annealing nickel strap screen is set to the central core of cable, described silver-plated annealed aluminium conductor is provided with 31, it is stranded that to be extruded in silver-plated annealing nickel strap screen inner, described zinc-plated annealing nickel conductor is provided with 24, evenly be extruded in silver-plated aluminium strip armour inner, described silver-plated annealed copper conductor is provided with 8, evenly be extruded between zinc-plated aluminium strip screen and crosslinked second propylene insulating barrier, it is 0.5 ㎜ that described silver-plated annealed aluminium leads cross-sectional diameter length, described zinc-plated annealing nickel conductors cross diameter length is 0.55 ㎜, described silver-plated annealed copper conductors cross diameter length is 0.60 ㎜.
The present invention has following beneficial effect in sum: this cable shield is effective, and electric conductivity is excellent, high pressure resistant, flame-resistant high-temperature-resistant, and tensile property is superior, is applicable to field of petrochemical industry and uses.
