Abstract

The utility model discloses a cold-resistant cable with a low-smoke low-halogen sheath. The cable is composes of aluminum alloy cable cores, a galvanized copper wire braided shielding layer, a belting layer, copper cable cores, a polyvinyl chloride insulating layer, an aluminum tape armored layer, a chloroprene rubber sheath layer and a low-smoke halogen-free polyethylene sheath layer. The number of the aluminum alloy cable cores is seven, the aluminum alloy cable cores are extruded in the galvanized copper wire braided shielding layer, the belting layer is extruded outside the galvanized copper wire braided shielding layer, twelve copper cable cores are extruded in the belting layer, a layer of polyvinyl chloride insulating layer is extruded outside the belting layer, and a layer of aluminum tape armored layer is extruded outside the polyvinyl chloride insulating layer. The cold-resistant cable exhibits a wide range in application and the long service life, can undergo cyclic bending up to 4 million times and has the advantages of being low in smoke, free of halogen and resistant to flame; and the cole-resistant cable also has the advantages of good performance of cold resistance, oil resistance and excellent performance of chemical resistance.

Description

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

Technical field

The utility model relates to field of cables, relates 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.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model 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 utility model 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 utlity model has in sum following beneficial effect: this kind of cable applications is extensive, long service life, can experience reversed bending and reach 4,000,000 times, there is the feature of low-smoke non-halogen flame-retardant, also have advantages of that cold tolerance is good, oil resistant and chemical-resistance good.
