Abstract

The invention discloses a perfluorinated-ethylene insulating protecting-cover wire, consisting of twenty-seven copper conductors, a galvanized aluminum wire shielding layer, a nickel strap shielding layer, a copper strap armor layer, a low-smoke halogen-free polyolefin sheath layer, a polyfluorinared ethylene propylene insulating layer and a chlorosulfonated polyethylene sheath layer, wherein the twenty-seven copper 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 nickel strap shielding layer; the nickel strap shielding layer is externally wrapped with the copper strap armor layer; the copper 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 polyfluorinated ethylene insulating sheath electric wire

Technical field

The invention belongs to electric wire field, relate in particular to a kind of polyfluorinated ethylene insulating sheath 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 double hyer insulation multilayer proofing cover electric wire for metallurgy generating that diamagnetic interference is good.

The present invention takes following technical scheme to realize: a kind of polyfluorinated ethylene insulating sheath electric wire, it is made up of copper conductor, zinc-plated aluminium wire screen, nickel strap screen, copper strips armour, low-smoke halogen-free polyolefin restrictive coating, perfluoroethylene-propylene insulating barrier and chlorosulfonated polyethylene sheath layer.Described copper 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 nickel strap screen, outside described nickel strap screen, wrap up one deck copper strips armour, outside described copper strips armour, wrap up one deck low-smoke halogen-free polyolefin restrictive coating, described nickel strap screen inside is extruded with 8 groups of nickel conductor cable cores, and described copper strips armour inside is extruded with 37 groups of aluminium conductor cable cores.

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.
