Abstract

The invention discloses an anti-freezing shielding armored insulaton cable which comprises three groups of cable cores, three copper metal hoses, a low-smoke zero-halogen polyolefin sheath layer, a nickel strip armored layer, a galvanized iron shielding layer and a polyvinyl chloride insulation layer. The three groups of cable cores are extruded inside the low-smoke zero-halogen polyolefin sheath layer, each groups of cable cores consists of a group of tin-plated nickel conductor wire cores, a group of silver-plated copper conductor wire cores, two groups of galvanized aluminum conductor wire cores and a nonmagnetic metal armored layer. A galvanized iron drainage wire is extruded in the tin-plated nickel conductor wire cores, and the three copper metal hoses are evenly extruded among the low-smoke zero-halogen polyolefin sheath layer, the nickel strip armored layer and the galvanized iron shielding layer. The anti-freezing shielding armored insulation cable ahs excellent anti-freezing performance, durable, high in shielding inhabitation index and good in tensile property and is not easily bent.

Description

A kind of freeze proof shield insulated cable

Technical field

The invention belongs to field of cables, particularly relate 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 object of this invention is to provide one have well resistance to freeze cold-resistant, the freeze proof shield insulated cable that shielding properties is excellent.

The present invention takes 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 by 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 present invention 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.

Fig. 1 is cross-sectional structure schematic diagram of the present invention;

Wherein: 1, zinc-plated nickel conductor thread core; 11, zinc-plated iron wire drainage thread; 2, silver-plated copper conductor thread core; 3, zinc-plated aluminium conductor core; 4, low-smoke halogen-free polyolefin restrictive coating; 5, nickel strap armour; 6, galvanized iron screen; 7, polyvinyl chloride insulation layer; 8, copper metal hose.

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 by 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 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.
