Abstract

The invention discloses an electric wire with double protecting sheaths and insulation layers for metallurgical power generation. The electric wire consists of 27 copper conductors, a galvanized aluminum wire shielding layer, a silicon rubber insulation layer, a polyvinyl chloride insulation layer, a polyester fiber layer, a fluorinated ethylene-propylene insulation layer, a chlorosulfonated polyethylene protecting sheath layer and an aluminum band armored polyethylene protecting sheath layer, wherein the 27 copper conductors are extruded together, the exteriors of the copper conductors are coated with the galvanized aluminum wire shielding layer, the exterior of the galvanized aluminum wire shielding layer is coated with the silicon rubber insulation layer, the exterior of the silicon rubber insulation layer is coated with the polyvinyl chloride insulation layer, and the exterior of the polyvinyl chloride insulation layer is coated with the polyester fiber layer. The electric wire has the advantages that the aging-resistant and oxidizing-resistant effects are realized, the service life is long, the cold-resistant effect is realized, the insulation performance is good, and the flexibility is realized, and meanwhile has the characteristic that the magnetic interference-resistant performance is good.

Description

A kind of two insulating sheath electric wires for metallurgical generating

Technical field

The invention belongs to electric wire field, relate in particular to the two insulating sheath electric wires of a kind of metallurgical generating.

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, two insulating sheath electric wires for metallurgy generating that diamagnetic interference is good.

The present invention takes following technical scheme to realize: a kind of two insulating sheath electric wires for metallurgical generating, it is by copper conductor, zinc-plated aluminium wire screen, silicone rubber insulation layer, polyvinyl chloride insulation layer, layer of polyester fiber, perfluoroethylene-propylene insulating barrier, chlorosulfonated polyethylene sheath layer and aluminium strip armouring pe sheath layer composition, 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 silicone rubber insulation layer, outside described silicone rubber insulation layer, wrap up one deck polyvinyl chloride insulation layer, outside described polyvinyl chloride insulation layer, wrap up one deck layer of polyester fiber, described silicone rubber insulation layer inside is extruded with 8 groups of nickel conductor cable cores, described polyvinyl chloride insulation layer inside is extruded with 37 groups of nickel conductor cable cores, described layer of polyester fiber inside is extruded with 16 groups of aluminium conductor cable cores, described perfluoroethylene-propylene insulating barrier inside is extruded with 16 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.
