Abstract

The invention discloses a composite thin-film insulated cable for aviation and aerospace. The composite thin-film insulated cable comprises metal hoses, copper conductors, a chloroprene rubber sheath layer, a polyester fiber layer, a low-smoke halogen-free polyolefin sheath layer, an ethylene propylene rubber layer, and an aluminum tape armor layer. The cable comprises seven conductor cores, and each conductor core is composed of one metal hose in the middle and six copper conductors arranged around the metal hose. The seven conductor cores are coated with the chloroprene rubber sheath layer, the chloroprene rubber sheath layer is coated with the polyester fiber layer, the polyester fiber layer is coated with the low-smoke halogen-free polyolefin sheath layer, and the low-smoke halogen-free polyolefin sheath layer is coated with the ethylene propylene rubber layer. The cable is especially applicable to the fields of aerospace, ship and the like, has the characteristics of excellent electrical property, good acid-base resistance property, high tear resistance, high magnetic force interference resistance, and good heat resistance, and can maintain the excellent electrical and mechanical performances in severe environments.

Description

A kind of Aero-Space laminated film insulated cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of Aero-Space laminated film insulated cable.

Background technology

At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, the cable such as used in the fields such as metallurgy, electric power, boats and ships, aviation, high all especially to the requirement of useful life of cable, electric conductivity, mechanical performance, coercive force interference and heat resistance aspect, only meet the requirements, could improve the fail safe during manufacturing in these fields.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of electric conductivity strong, anti-tear drawing property is strong, the Aero-Space laminated film insulated cable that shielding properties is excellent.

The present invention takes following technical scheme to realize: a kind of Aero-Space laminated film insulated cable, it comprises metal hose, copper conductor, chloroprene rubber sheath layer, layer of polyester fiber, low-smoke halogen-free polyolefin restrictive coating, ethylene propylene rubber insulated layer and aluminium strip armour, this cable conductor cable core has seven groups, often organize and be all made up of the described metal hose at middle part and the six roots of sensation copper conductor be wrapped in around metal hose, outer wrapping one deck chloroprene rubber sheath layer of seven groups of conductor cable cores, outer wrapping one deck layer of polyester fiber of described chloroprene rubber sheath layer, outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating of described layer of polyester fiber, the ethylene propylene rubber insulated layer of outer wrapping one deck of described low-smoke halogen-free polyolefin restrictive coating.

32 nickel conductors are provided with in described chloroprene rubber sheath layer.

Outer wrapping one deck perfluoroethylene-propylene insulating barrier of described metal hose.

Described low-smoke halogen-free polyolefin restrictive coating inside is provided with a nickel wire drainage thread.

The present invention has following beneficial effect in sum: the present invention is specially adapted in the field such as space flight, boats and ships, this kind of cable has superior electrical property, strong, anti-tear the drawing property of resistance to acids and bases is strong, coercive force interference and heat-resisting feature, the electric property that can it be kept in rugged environment superior and mechanical performance.
