Abstract
The invention discloses a high-temperature-resistant flame-retardant tensile electric wire. The high-temperature-resistant flame-retardant tensile electric wire consists of an aluminum metal hose, four protective sleeve layers wrapped outside the aluminum metal hose, six control wire cores and six grounding wire cores, wherein the four protective sleeve layers are respectively a low-smoke halogen-free butyronitrile insulated layer, an aluminum belt armor layer, a tinned nickel belt armor layer and a low-smoke halogen-free polyolefin protective sleeve layer from the inside to the outside; the aluminum metal hose and the six control wire cores are wrapped inside the low-smoke halogen-free butyronitrile insulated layer; the aluminum metal hose is placed on a center position; the six grounding wire cores are uniformly wrapped among the low-smoke halogen-free butyronitrile insulated layer, the aluminum belt armor layer and the tinned nickel belt armor layer. The high-temperature-resistant flame-retardant tensile electric wire is durable in use, high-temperature-resistant and flame-retardant; through the support of the aluminum alloy metal hose and the steel wire tensile line, the tensile performances of the electric wire are strengthened.
Description
Technical field
The invention belongs to electric wire field, particularly relate to a kind of heat-resistant fireproof 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 heat-resistant fireproof tension electric wire with good tensile property and resistance to elevated temperatures.
The present invention takes following technical scheme to realize: a kind of heat-resistant fireproof 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, aluminium strip armour, 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 aluminium strip armour and zinc-plated nickel strap armour, described control conductor is by zinc-plated aluminium alloy conductor, aluminium strip armouring polyethylene layer and layer of polyester fiber composition.
Described layer of polyester fiber inside is extruded with a steel wire tensile cord.
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 steel wire tensile cord, enhances the tensile property of this electric wire.
