Abstract

The utility model discloses an aviation polyester fiber armor shield cable comprising four sets of earthing cable cores, a tinning Ni belt shield layer, an aluminium belt shield layer, a polyester fiber layer, a non-magnetic metal armor layer and a neoprene sheath layer; the four sets of earthing cable cores are wrapped by the tinning Ni belt shield layer; the tinning Ni belt shield layer is wrapped by the aluminium belt shield layer; the aluminium belt shield layer is wrapped by the polyester fiber layer; the polyester fiber layer is wrapped by the non-magnetic metal armor 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 polyester fiber sheathed shielded cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of aviation polyester fiber 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 to, in the middle of aviation field, ensure safety.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model be to provide a kind of have heat-resisting, good insulation preformance, the aviation of resistant to elevated temperatures advantage polyester fiber sheathed shielded cable.

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

Described ground connection cable core is comprised 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 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.
