Abstract
The utility model discloses a polytetrafluoroethylene insulating protective sleeve wire, which is composed of a copper conductor, a galvanized aluminum wire shielding layer, a nickel belt shielding layer, a steel belt armor layer, a low smoke halogen-free polyolefin sheath layer, an FEP insulating layer, and a chlorosulfonation polyethylene sheath layer. 27 copper conductors are provided and are extruded together, and then are covered with one galvanized aluminum wire shielding layer; the galvanized aluminum wire shielding layer is covered with one nickel belt shielding layer; the nickel belt shielding layer is covered with one copper belt armor layer; and the copper belt armor layer is wrapped with one low smoke halogen-free polyolefin sheath. The polytetrafluoroethylene insulating protective sleeve wire is resistant to aging, resistant to oxidization, and long in service life, has the advantages of being resistant to coldness, good in insulation, great in softness, and has the characteristics of being great in anti magnetic interference.
Description
Technical field
The utility model belongs to electric wire field, relates 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.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of environmental protection, has softness, good insulation preformance, the double hyer insulation multilayer proofing cover electric wire for metallurgy generating that diamagnetic interference is good.
The utility model 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 utlity model has in sum following beneficial effect: 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.
