Abstract

The invention discloses a multiple conductor cable core insulated and shielded cable for aviation. The cable is composed of copper conductor cable cores, a tinned copper belt shielding layer, a butyronitrile insulating layer, a silicone rubber insulating layer, a nickel belt shielding layer and a chloroprene rubber sheath layer. The ten sets of copper conductors are arranged and wrapped by the tinned copper belt shielding layer, the tinned copper belt shielding layer is wrapped by the butyronitrile insulating layer, the butyronitrile insulating layer is wrapped by the silicone rubber insulating layer, and the silicone rubber insulating layer is wrapped by the nickel belt shielding layer. The cable has the advantages of being low in installing and laying temperature, long in service life, resistant to high temperature, good in insulativity, flexible and excellent in electric stability under the high temperature environment and conductivity.

Description

A kind of many conductors cable core insulation shielding cable for aviation

Technical field

The invention belongs to field of cables, relate in particular to a kind of many conductors of aviation cable core insulation shielding 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, many conductors cable core insulation shielding cable for the aviation of resistant to elevated temperatures advantage.

The present invention takes following technical scheme to realize: a kind of many conductors of aviation cable core insulation shielding cable, it is by copper conductor cable core, tin-coated copper strip screen, butyronitrile insulating barrier, silicone rubber insulation layer, nickel strap screen and chloroprene rubber sheath layer composition, described copper conductor cable core is set to ten groups, outside ten groups of copper conductor cable cores, wrap up one deck tin-coated copper strip screen, outside described tin-coated copper strip screen, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, wrap up one deck silicone rubber insulation layer, described tin-coated copper strip screen inside is extruded with four groups of aluminium conductor cable cores and four groups of nickel conductor cable cores, described aluminium conductor cable core and nickel conductor cable core space arrange, described butyronitrile insulating barrier inside is extruded with 8 aluminium alloy conductors.

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.
