Abstract

The invention discloses a low-smoke low-halogen cold-resistant sheath cable. The low-smoke low-halogen cold-resistant sheath cable is composed of seven aluminum alloy cable cores, a galvanized copper wire braided shielding layer, a wrapping tape layer, twelve copper cable cores, a polyvinyl chloride insulating layer, an aluminum strip armor layer, a chloroprene rubber sheath layer and a low-smoke zero-halogen polyethylene sheath layer. The seven aluminum alloy cable cores are extruded in the galvanized copper wire braided shielding layer. The wrapping tape layer is extruded outside the galvanized copper wire braided shielding layer. The twelve copper cable cores are extruded in the wrapping tape layer. The polyvinyl chloride insulating layer is extruded outside the wrapping tape layer. The aluminum strip armor layer is extruded outside the polyvinyl chloride insulating layer. The low-smoke low-halogen cold-resistant sheath cable is wide in usage, long in service life and capable of being bent cyclically for four million times, has the advantages of low smoke, zero halogen and flame retarding, and also has the advantages of being good in cold-resisting performance and excellent in oil-resisting performance and chemical-resisting performance.

Description

The low Lu's sheath of a kind of low cigarette cold resistant cable

Technical field

The present invention relates to field of cables, relate in particular to the low Lu's sheath of a kind of low cigarette cold resistant cable.

Background technology

At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in aviation, boats and ships, field of petrochemical industry, to the low-smoke non-halogen flame-retardant of cable, cold tolerance, oil resistant and chemical-resistance aspect, require all high especially.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of low-smoke non-halogen flame-retardant, the low Lu's sheath of low cigarette cold resistant cable that cold tolerance is good.

The present invention takes following technical scheme to realize: the low Lu's sheath of a kind of low cigarette cold resistant cable, it is by aluminium alloy cable core, zinc-plated copper wire woven shield, belting layer, copper cable core, polyvinyl chloride insulation layer, aluminium strip armour, chloroprene rubber sheath layer and low smoke and zero halogen pe sheath layer form, described aluminium alloy cable core is seven, be extruded in zinc-plated copper wire woven shield inner, described zinc-plated copper wire woven shield is extruded with one deck belting layer outward, described belting layer inside is extruded with 12 copper cable cores, described belting layer is extruded with one deck polyvinyl chloride insulation layer outward, described polyvinyl chloride insulation layer is extruded with one deck aluminium strip armour outward.

Described aluminium alloy cable core is comprised of aluminium alloy conductor and the nonmagnetic metal armour and the chlorosulfonated polyethylene sheath layer that are wrapped in outside aluminium alloy conductor.

Described copper cable core is comprised of copper conductor and the nonmagnetic metal armour and the chlorosulfonated polyethylene sheath layer that are wrapped in outside copper conductor.

The present invention has following beneficial effect in sum: this kind of cable applications is extensive, and long service life can experience reversed bending and reach 4,000,000 times, has the feature of low-smoke non-halogen flame-retardant, also have advantages of that cold tolerance is good, oil resistant and chemical-resistance good.

Accompanying drawing explanation

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

Wherein: 1, aluminium alloy cable core; 2, zinc-plated copper wire woven shield; 3, belting layer; 4, copper cable core; 5, polyvinyl chloride insulation layer; 6, aluminium strip armour; 7, chloroprene rubber sheath layer; 8, low smoke and zero halogen pe sheath layer.

Embodiment

As shown in Figure 1, the low Lu's sheath of a kind of low cigarette cold resistant cable, it is by aluminium alloy cable core 1, zinc-plated copper wire woven shield 2, belting layer 3, copper cable core 4, polyvinyl chloride insulation layer 5, aluminium strip armour 6, chloroprene rubber sheath layer 7 and low smoke and zero halogen pe sheath layer 8 form, described aluminium alloy cable core 1 is seven, be extruded in zinc-plated copper wire woven shield 2 inside, the outer one deck belting layer 3 that is extruded with of described zinc-plated copper wire woven shield 2, described belting layer 3 inside are extruded with 12 copper cable cores 4, the outer one deck polyvinyl chloride insulation layer 5 that is extruded with of described belting layer 3, the outer one deck aluminium strip armour 6 that is extruded with of described polyvinyl chloride insulation layer 5.

Embodiment: aluminium alloy cable core 1 is comprised of aluminium alloy conductor and the nonmagnetic metal armour and the chlorosulfonated polyethylene sheath layer that are wrapped in outside aluminium alloy conductor.

Copper cable core 4 is comprised of copper conductor and the nonmagnetic metal armour and the chlorosulfonated polyethylene sheath layer that are wrapped in outside copper conductor.

It is 70 ℃ that this cable allows operational environment maximum temperature; The permission bending radius of this cable is the outside diameter of cable 8 times.

The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
