Abstract
The utility model discloses a kind of freeze proof shield insulated cable, it comprises three groups of cable cores, three copper metal hoses, low-smoke halogen-free polyolefin restrictive coating, nickel strap armour, galvanized iron screen and polyvinyl chloride insulation layers.Three groups of cable cores are extruded in low-smoke halogen-free polyolefin restrictive coating inside, often organize cable core to be made up of zinc-plated nickel conductor thread core one group, silver-plated copper conductor thread core one group, zinc-plated aluminium conductor core two groups and nonmagnetic metal armour, be extruded with a zinc-plated iron wire drainage thread in described zinc-plated nickel conductor thread core, described three copper metal hoses are evenly extruded between low-smoke halogen-free polyolefin restrictive coating, nickel strap armour and galvanized iron screen.This kind of cable has excellent anti-freezing property, durable in use, and shielding inhibition index is high, and tensile property is strong, not flexible.
Description
Technical field
The utility model belongs to field of cables, particularly relates to a kind of freeze proof shield insulated cable.
Background technology
Cable has electric conductivity, be widely used in each different field, relating to people's lives, industrial production every field, so the consumption of cable is huge especially, is also important especially, also can be more and more higher to the requirement of quality, but in every field and each area, the quality purposes of cable is required it is different, as at oil, chemical industry and time, the Northeast's industrial production cable in the winter time, requirement frozen to cable cold-resistant resistance to high especially, could be durable in use, satisfy the demand.
Summary of the invention
In order to increase the practicality of prior art, the purpose of this utility model be to provide one have well resistance to freeze cold-resistant, the freeze proof shield insulated cable that shielding properties is excellent.
The utility model is taked following technical scheme to realize: a kind of freeze proof shield insulated cable, it comprises three groups of cable cores, three copper metal hoses, low-smoke halogen-free polyolefin restrictive coating, nickel strap armour, galvanized iron screen and polyvinyl chloride insulation layer, three groups of cable cores are extruded in low-smoke halogen-free polyolefin restrictive coating inside, nickel strap armour is extruded with successively outside described low-smoke halogen-free polyolefin restrictive coating, galvanized iron screen and polyvinyl chloride insulation layer, often organizing cable core is by zinc-plated nickel conductor thread core one group, silver-plated copper conductor thread core one group, zinc-plated aluminium conductor core two groups and nonmagnetic metal armour composition, described zinc-plated nickel conductor thread core is by zinc-plated nickel conductor, ethylene propylene rubber insulated layer and silver-plated aluminium strip pe sheath layer composition, described silver-plated aluminium strip pe sheath layer inside is extruded with a zinc-plated iron wire drainage thread, described silver-plated copper conductor thread core is made up of silver-plated copper conductor and butyronitrile insulating barrier, described zinc-plated aluminium conductor core is made up of zinc-plated aluminium conductor and carbon fiber insulating barrier.
Described three copper metal hoses are evenly extruded between low-smoke halogen-free polyolefin restrictive coating, nickel strap armour and galvanized iron screen.
The utility model has following beneficial effect in sum: this kind of cable has excellent anti-freezing property, durable in use, and shielding inhibition index is high, and tensile property is strong, not flexible.

Embodiment
As shown in Figure 1, a kind of freeze proof shield insulated cable, it comprises three groups of cable cores, three copper metal hoses 8, low-smoke halogen-free polyolefin restrictive coating 4, nickel strap armour 5, galvanized iron screen 6 and polyvinyl chloride insulation layer 7, three groups of cable cores are extruded in low-smoke halogen-free polyolefin restrictive coating 4 inside, nickel strap armour 5 is extruded with successively outside described low-smoke halogen-free polyolefin restrictive coating 4, galvanized iron screen 6 and polyvinyl chloride insulation layer 7, often organizing cable core is by zinc-plated nickel conductor thread core 1 one groups, silver-plated copper conductor thread core 2 one groups, zinc-plated aluminium conductor core 3 liang of groups and nonmagnetic metal armour composition, described zinc-plated nickel conductor thread core 1 is by zinc-plated nickel conductor, ethylene propylene rubber insulated layer and silver-plated aluminium strip pe sheath layer composition, described silver-plated aluminium strip pe sheath layer inside is extruded with a zinc-plated iron wire drainage thread 11, described silver-plated copper conductor thread core 2 is made up of silver-plated copper conductor and butyronitrile insulating barrier, described zinc-plated aluminium conductor core 3 is made up of zinc-plated aluminium conductor and carbon fiber insulating barrier.
Described three copper metal hoses 8 are evenly extruded between low-smoke halogen-free polyolefin restrictive coating 4, nickel strap armour 5 and galvanized iron screen 6.
Further, described copper metal hose 8 cross-sectional diameter length is 3 ㎜; Described zinc-plated nickel conductors cross diameter length is 0.5 ㎜; Described silver-plated copper conductors cross diameter length is 1 ㎜; Described zinc-plated aluminium conductor cross-sectional diameter length is 0.5 ㎜.
This cable allows operational environment maximum temperature to be 75 DEG C, and the minimum temperature of mounting and installation is-20 DEG C; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown; The shielding rejection coefficient of this cable is less than 0.7.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
