Abstract

The utility model discloses an aviation armor insulation cable comprising four sets of earthing cable cores, a tinning nickel wire shield layer, a butyronityile insulating layer, a Ni belt armor layer, a non-magnetic metal armor layer and an aluminium belt armor polyethylene sheath layer; the four sets of earthing cable cores are wrapped by the tinning nickel wire shield layer; the tinning nickel wire shield layer is wrapped by the butyronityile insulating layer; the butyronityile insulating layer is wrapped by the Ni belt armor layer; the Ni belt armor layer is wrapped by the non-magnetic metal armor layer; the non-magnetic metal armor layer is wrapped by the aluminium belt armor polyethylene sheath layer. The cable is low in mounting paving temperature, long in service life, high temperature resistant, good in insulation, soft, excellent in high temperature environment electric stability, and good in conductivity.

Description

A kind of aviation armouring insulated cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of aviation armouring insulated 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.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model be to provide one have heat-resisting, good insulation preformance, the aviation of resistant to elevated temperatures advantage armouring insulated cable.

The utility model takes following technical scheme to realize: a kind of aviation armouring insulated cable, it is made up of ground connection cable core, zinc-plated nickel wire screen, butyronitrile insulating barrier, nickel strap armour, nonmagnetic metal armour and aluminium strip armouring pe sheath layer.Described ground connection cable core is set to four groups, outside four groups of ground connection cable cores, wrap up the zinc-plated nickel wire screen of one deck, outside described zinc-plated nickel wire screen, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, wrap up one deck nickel strap armour, outside described nickel strap armour, wrap up one deck nonmagnetic metal armour, outside described nonmagnetic metal armour, wrap up one deck aluminium strip armouring pe sheath layer, described ground connection cable core inside is extruded with 10 copper conductors, and described butyronitrile insulating barrier inside is extruded with 16 tinned copper conductors.

The utlity model has in sum following beneficial effect: 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.

Brief description of the drawings

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, ground connection cable core; 2, zinc-plated nickel wire screen; 3, butyronitrile insulating barrier; 4, nickel strap armour; 5, nonmagnetic metal armour; 6, aluminium strip armouring pe sheath layer; 7, copper conductor; 8, tinned copper conductor.

Embodiment

As shown in Figure 1, a kind of aviation armouring insulated cable, it is made up of ground connection cable core 1, zinc-plated nickel wire screen 2, butyronitrile insulating barrier 3, nickel strap armour 4, nonmagnetic metal armour 5 and aluminium strip armouring pe sheath layer 6.Described ground connection cable core 1 is set to four groups, outside four groups of ground connection cable cores 1, wrap up the zinc-plated nickel wire screen 2 of one deck, outside described zinc-plated nickel wire screen 2, wrap up one deck butyronitrile insulating barrier 3, outside described butyronitrile insulating barrier 3, wrap up one deck nickel strap armour 4, outside described nickel strap armour 4, wrap up one deck nonmagnetic metal armour 5, outside described nonmagnetic metal armour 5, wrap up one deck aluminium strip armouring pe sheath layer 6, described ground connection cable core 1 inside is extruded with 10 copper conductors 7, and described butyronitrile insulating barrier 3 inside are extruded with 16 tinned copper conductors 8.

The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
