Abstract
The invention discloses a low smoke halogen-free flame retardant tensile wire. The low smoke halogen-free flame retardant tensile wire is composed of the aluminum metal flexible tube, four layers of sheath layers covered outside the aluminum metal flexible tube, six strands of control wire cores and six strands of ground wire cores. Four layers of sheath layers are as follows: low smoke halogen-free butyronitrile insulation layer, tin plating copper belt shielding layer, tin plating nickel belt armor layer and low smoke halogen-free polyolefin sheath layer, the aluminum metal flexible tube and six strands of control wire cores are extruded in the low smoke halogen-free butyronitrile insulation layer, the aluminum metal flexible tube is located at the centre, six strands of ground wire cores are evenly and symmetrically extruded among the low smoke halogen-free butyronitrile insulation layer, the tin plating copper belt shielding layer and the tin plating nickel belt armor layer. The wire has durable, high temperature resistant and inflaming retarding properties, the tensile property of the cable is strengthened the through the support of the aluminum metal flexible tube and the copper metal flexible tube.
Description
Technical field
The invention belongs to electric wire field, particularly relate to a kind of low-smoke non-halogen flame-retardant tension electric wire.
Background technology
Electric wire is widely used in every field, relate to people's lives, industrial production every field, so the consumption of electric wire 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 electric wire, just require that electric wire has good tensile property and resistance to elevated temperatures, 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 a kind of low-smoke non-halogen flame-retardant tension electric wire with good tensile property and resistance to elevated temperatures.
The present invention takes following technical scheme to realize: a kind of low-smoke non-halogen flame-retardant tension electric wire, it is by aluminum metal flexible pipe, wrapped four layers of restrictive coating outside aluminum metal flexible pipe, six strands of control conductor and six strands of ground connection core compositions, four layers of restrictive coating are followed successively by low smoke and zero halogen butyronitrile insulating barrier from inside to outside, tin-coated copper strip screen, zinc-plated nickel strap armour and low-smoke halogen-free polyolefin restrictive coating, described aluminum metal flexible pipe is extruded in low smoke and zero halogen butyronitrile insulating barrier center, six strands of control conductor are extruded in low smoke and zero halogen butyronitrile insulating barrier, be evenly distributed on around aluminum metal flexible pipe, six strands of ground connection cores are extruded in low smoke and zero halogen butyronitrile insulating barrier symmetrically, between tin-coated copper strip screen and zinc-plated nickel strap armour, described control conductor is by zinc-plated aluminium alloy conductor, tin-coated copper strip shielding polyethylene layer and layer of polyester fiber composition.
Described ground connection core is made up of zinc-plated annealed copper conductor and the zinc-plated aluminium alloy armored layer be wrapped in outside zinc-plated annealed copper conductor.
Six roots of sensation copper metal hose is evenly extruded with between described tin-coated copper strip screen and zinc-plated nickel strap armour.
The present invention has following beneficial effect in sum: this kind of electric wire is durable in use, high temperature resistant, fire-retardant, by the support of aluminum metal flexible pipe and copper metal hose, enhances the tensile property of this electric wire.
