Abstract

Disclosed in the utility model is a composite thin-film insulated cable for aerospace. The composite thin-film insulated cable consists of flexible metal tubes, 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 aluminium tape armor layer. According to the cable, seven groups of conductor cores are arranged; and each group of conductor cores are formed by the flexible metal tube in the middle and six copper conductors encircling and coating the flexible metal tube. The outside of the seven groups of conductor cores are coated with the chloroprene rubber sheath layer; the outside of the chloroprene rubber sheath layer is coated with the polyester fiber layer; the outside of the polyester fiber layer is coated with low-smoke halogen-free polyolefin sheath layer; and the outside of the low-smoke halogen-free polyolefin sheath layer is coated with the ethylene propylene rubber layer. According to the scheme, the provided cable is especially suitable for the fields of spaceflight and ship and the like and has characteristics of excellent electrical property, good acid-base resistance property, high tear growth resistance, high magnetic force interference resistance, and good heat resistance; and the excellent electrical and mechanical performances can be maintained in the severe environment.

Description

A kind of Aero-Space laminated film insulated cable

Technical field

The utility model belongs to field of cables, relates in particular 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, such as the cable using in the fields such as metallurgy, electric power, boats and ships, aviation, useful life to cable, electric conductivity, mechanical performance, coercive force disturb and the requirement of heat resistance aspect all high especially, only meet the requirements, the fail safe could improve the manufacturing in these fields time.

Utility model content

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

The utility model 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, every group is all made up of the described metal hose at middle part and the six roots of sensation copper conductor being wrapped in around metal hose, outside seven groups of conductor cable cores, wrap up one deck chloroprene rubber sheath layer, outside described chloroprene rubber sheath layer, wrap up one deck layer of polyester fiber, outside described layer of polyester fiber, wrap up one deck low-smoke halogen-free polyolefin restrictive coating, outside described low-smoke halogen-free polyolefin restrictive coating, wrap up the ethylene propylene rubber insulated layer of one deck.

In described chloroprene rubber sheath layer, be provided with 32 nickel conductors.

Outside described metal hose, wrap up one deck perfluoroethylene-propylene insulating barrier.

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

The utlity model has in sum following beneficial effect: the utility model 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 disturbs and heat-resisting feature, can in rugged environment, keep its superior electric property and mechanical performance.
