Abstract

The invention discloses a heat-resistant armour sheathed wire. The heat-resistant armour sheathed wire is composed of two kinds of conductor wire cores, an aluminium alloy metal hose and five outer protective layers; the five outer protective layers are a polychloro polyethylene insulation layer, a tin-plated nickel strip armour layer, a nickel strip armour layer, a chlorosulfonated ethylene propylene sheathed layer and a tin-plated nickel strip amour ethylene propylene sheathed layer sequentially from inside to outside; the two kinds of conductor wire cores are two sets of tin-plated nickel conductor wire cores and two sets of silver-plated annealing copper conductor wire cores; both the two sets of tin-plated nickel conductor wire cores and the two sets of silver-plated annealing copper conductor wire cores are uniformly extruded in the polychloro polyethylene insulation layer; seven conductors are extruded in the tin-plated nickel conductor wire cores; seven conductors are extruded in the silver-plated annealing copper conductor wire cores; and the aluminium alloy metal hose is extruded among the two sets of tin-plated nickel conductor wire cores and penetrates the outmost layer of the two sets of tin-plated nickel conductor wire cores. The cable disclosed by the invention is waterproof, high-temperature resistant, high in fire resistant, tensile, light and flexible.

Description

A kind of heat-resisting armouring protective case wire

Technical field

The invention belongs to field of cables, particularly relate to a kind of heat-resisting armouring protective case wire.

Background technology

Electric wire is a kind of conductive media, is widely used in petrochemical industry, the every field such as computer, national defence.Electric wire is normally by the cable of several or the stranded similar rope of several groups of wires [often organizing at least two]; often organize mutually insulated between wire; and be often twisted into round a center; whole outside is surrounded by the cover layer of high-insulation; but the inner conductor of cable and external protection structure varied, according to different field need especially can be different.

Summary of the invention

In order to increase the practicality of prior art, the invention provides a kind of light, soft, high temperature resistant, heat-resisting armouring protective case wire.

The present invention takes following technical scheme to realize: a kind of heat-resisting armouring protective case wire, it is by two kinds of conductor thread cores, an Al-alloy metal flexible pipe and five layers of external protection composition, five layers of external protection are followed successively by polychlorostyrene polyethylene layer from inside to outside, zinc-plated nickel strap armour, nickel strap armour, chlorosulfonation second propylene restrictive coating and zinc-plated nickel strap armouring second propylene restrictive coating, two kinds of conductor thread cores are respectively zinc-plated nickel conductor thread core and silver-plated annealed copper conductor thread core, respectively arrange two groups, all evenly be extruded in polychlorostyrene polyethylene layer inner, described zinc-plated nickel conductor thread core is by seven zinc-plated nickel conductors, one deck chloroprene rubber sheath layer, the zinc-plated nickel strap armour of one deck, one deck low smoke and zero halogen pe sheath layer, a nickel wire drainage thread and a zinc-plated copper wire drainage thread composition, nickel wire drainage thread pierces into low smoke and zero halogen pe sheath layer, polychlorostyrene polyethylene layer and zinc-plated nickel strap armour, zinc-plated copper wire drainage thread pierces into low smoke and zero halogen pe sheath layer and polychlorostyrene polyethylene layer, described Al-alloy metal flexible pipe to be extruded between two groups of zinc-plated nickel conductor thread cores and to pierce into the low smoke and zero halogen pe sheath layer of two groups of zinc-plated nickel conductor thread cores, described silver-plated annealed copper conductor thread core is by seven silver-plated annealed copper conductors, the zinc-plated aluminium strip armour of one deck, aluminium strip screen and an aluminium wire drainage thread composition, described aluminium wire drainage thread is arranged in aluminium strip screen and passes aluminium strip screen in polychlorostyrene polyethylene layer.

Described Al-alloy metal flexible pipe outer wrapping one deck butyronitrile insulating barrier.

The present invention has following beneficial effect in sum: this kind of cable waterproof is high temperature resistant, and anti-flammability is strong, and pull resistance is strong, and light, soft.
