Abstract

The invention discloses a nonmagnetic metal armor shielding cable for aviation. The nonmagnetic metal armor shielding cable for aviation is composed of four grounded cable cores, a copper strip shielding layer, a tinned nickel wire shielding layer, a polyester fiber layer, a nonmagnetic metal armor layer and an aluminum strip armor polyethylene jacket layer. The four grounded cable cores are wrapped by the copper strip shielding layer. The copper strip shielding layer is wrapped by the tinned nickel wire shielding layer. The tinned nickel wire shielding layer is wrapped by the polyester fiber layer. The polyester fiber layer is wrapped by the nonmagnetic metal armor layer. The nonmagnetic metal armor shielding cable for aviation is low in installation and laying temperature, and long in service life, and has the advantages of being resistant to high temperature, good in insulativity, flexible, and excellent in electrical stability and conductivity in the high-temperature environment.

Description

A kind of aviation nonmagnetic metal sheathed shielded cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of aviation nonmagnetic metal sheathed shielded cable.

Background technology

Cable refers to the wire of conduction current, is widely used in every field, in the middle of cable for aviation, indices to cable is had relatively high expectations, heat-resisting such as requiring to have, insulation, the characteristic of heat-resisting quantity and electric conductivity, just can be applied in the middle of aviation field, ensures safety.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one have heat-resisting, good insulation preformance, the aviation of resistant to elevated temperatures advantage nonmagnetic metal sheathed shielded cable.

The present invention takes following technical scheme to realize: a kind of aviation nonmagnetic metal sheathed shielded cable, it is by ground connection cable core, copper strip shielding layer, zinc-plated nickel wire screen, layer of polyester fiber, nonmagnetic metal armour and aluminium strip armouring pe sheath layer composition, described ground connection cable core is set to four groups, outside four groups of ground connection cable cores, wrap up one deck copper strips screen, outside described copper strip shielding layer, wrap up the zinc-plated nickel wire screen of one deck, outside described zinc-plated nickel wire screen, wrap up one deck layer of polyester fiber, outside described layer of polyester fiber, wrap up one deck nonmagnetic metal armour, described zinc-plated nickel wire screen inside is extruded with 16 tinned copper conductors.

Described ground connection cable core is made up of 10 copper conductors of centre, 16 nickel conductors being wrapped in 10 butyronitrile insulating barriers outside copper conductor and being extruded in butyronitrile insulating barrier inside.

The present invention has following beneficial effect in sum: this kind of cable installation temperature is low, long service life, have high temperature resistant, good insulating, soft advantage also has hot environment electric stability excellent, the feature that electric conductivity is excellent simultaneously.
