Abstract

The utility model discloses a polyester fiber nickel belt armor drainage wire which is composed of an aluminum alloy conductor, a galvanized aluminum wire shielding layer, a polyester fiber layer, a nickel belt armor layer, a low smoke halogen-free polyolefin sheath layer, an FEP insulating layer and a nonmagnetic metal armor layer. 27 aluminum alloy conductors are provided and are extruded together, and are covered with one galvanized aluminum wire shielding layer; the galvanized aluminum wire shielding layer is covered with one polyester fiber layer; the polyester fiber layer is covered with one nickel belt armor layer; and the nickel belt armor layer is covered with one low smoke halogen-free polyolefin sheath. The polyester fiber nickel belt armor drainage 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

A kind of polyester fiber nickel strap armouring drainage electric wire

Technical field

The utility model belongs to electric wire field, relates 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.

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 polyester fiber nickel strap armouring drainage electric wire that diamagnetic interference is good.

The utility model takes following technical scheme to realize: a kind of polyester fiber nickel strap armouring drainage electric wire, it is comprised 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 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.
