Abstract

The invention discloses a polyester-fiber nickel strap armor drain wire, consisting of twenty-seven aluminum conductors, a galvanized aluminum wire shielding layer, a polyester fiber layer, a nickel strap armor layer, a low-smoke halogen-free polyolefin sheath layer, a polyfluorinared ethylene propylene insulating layer and a nonmagnetic metal armor layer, wherein the twenty-seven aluminum conductors are extruded together, and are externally wrapped with the galvanized aluminum wire shielding layer; the galvanized aluminum wire shielding layer is externally wrapped with the polyester fiber layer; the polyester fiber layer is externally wrapped with the nickel strap armor layer; the nickel strap armor layer is externally wrapped with the low-smoke halogen-free polyolefin sheath layer. The wire has the advantages of aging resistance, oxidation resistance, long service life, cold resistance, good insulativity and flexibility, as well as the characteristics of excellent magnetic disturbance resistance.

Description

A kind of polyester fiber nickel strap armouring drainage electric wire

Technical field

The invention belongs to electric wire field, relate in particular to a kind of polyester fiber nickel strap armouring drainage electric wire.

Background technology

Electric wire refers to the wire of conduction current, be widely used in petrochemical industry, metallurgical generating, square, tunnel every field, these fields require all high to the indices of electric wire, such as requiring to there is resistance to oxidation, cold-resistant, insulation, soft, diamagnetic interference, tension is the durable and characteristic that conducts electricity very well firmly, just can ensure safety.

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 environmental protection, there is softness, good insulation preformance, the polyester fiber nickel strap armouring drainage electric wire that diamagnetic interference is good.

The present invention takes following technical scheme to realize: a kind of polyester fiber nickel strap armouring drainage electric wire, it is made up of aluminium alloy conductor, zinc-plated aluminium wire screen, layer of polyester fiber, nickel strap armour, low-smoke halogen-free polyolefin restrictive coating, perfluoroethylene-propylene insulating barrier and nonmagnetic metal armour.Described aluminium alloy conductor is provided with 27, outside being extruded in together, wrap up the zinc-plated aluminium wire screen of one deck, outside described zinc-plated aluminium wire screen, wrap up one deck layer of polyester fiber, outside described layer of polyester fiber, wrap up one deck nickel strap armour, outside described nickel strap armour, wrap up one deck low-smoke halogen-free polyolefin restrictive coating, described layer of polyester fiber inside is extruded with 8 groups of nickel conductor cable cores, and described nickel strap armour inside is extruded with 37 groups of aluminium conductor cable cores.

Between described low-smoke halogen-free polyolefin restrictive coating and perfluoroethylene-propylene insulating barrier, be extruded with two zinc-plated copper wire drainage threads.

The present invention has following beneficial effect in sum: this kind of electric wire is ageing-resistant, resistance to oxidation, long service life, have cold-resistant, good insulating, soft advantage also has the excellent feature of diamagnetic interference simultaneously.
