Abstract
The utility model discloses an armor shielding flexible wire for a tunnel and square The armor shielding flexible wire for the tunnel and square is composed of an aluminum alloy conductor cable core, a nickel belt armor layer, a copper belt shielding layer, a butyronitrile insulating layer, an aluminum belt shielding layer and an aluminum belt armor PVC sheath layer. The nickel belt armor layer is internally provided with seven groups of aluminum alloy conductor cable core which are formed by extrusion; the nickel belt armor layer is coated with one copper belt shielding layer; the copper belt shielding layer is wrapped with one butyronitrile insulating layer; and the butyronitrile insulating layer is coated with one aluminum belt shielding layer. The armor shielding flexible wire for the tunnel and square 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 conduction performance and great in anti magnetic interference.
Description
Technical field
The utility model belongs to electric wire field, relates in particular to square, a kind of tunnel armouring and shields cord.
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, and the square, tunnel of resistant to elevated temperatures advantage shields cord with armouring.
The utility model takes following technical scheme to realize: square, a kind of tunnel armouring shields cord, it is by aluminium alloy conductor cable core, nickel strap armour, copper strip shielding layer, butyronitrile insulating barrier, aluminium strip screen and aluminium strip armouring pe sheath layer composition, the inner setting of described nickel strap armour is extruded with seven group aluminum alloy conductor cable cores, outside described nickel strap armour, be enclosed with one deck copper strips screen, outside described copper strip shielding layer, be enclosed with one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, be enclosed with one deck aluminium strip screen, described aluminium alloy conductor cable core inside is extruded with 27 aluminium alloy conductors.
Described copper strip shielding layer inside is also extruded with 16 groups of tinned copper 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 electric conductivity excellent, the feature that diamagnetic interference is excellent simultaneously.
