Abstract

The utility model discloses an aviation cable and relates to a cable, comprising a cable core and a protective sleeve packaged outside the cable core, a filling layer is arranged between the protective sleeve and the cable core, the cable core is formed by twisting a plurality of insulation conductor cores, the insulation conductor core consists of a conductor and an insulating layer packaged outside the conductor, the insulating layer is in a four-layer composite structure and comprises an organic insulating layer, an inner inorganic insulating layer, an outer inorganic insulating layer and an insulation shielding layer from inside to outside sequentially, and the protective sleeve is in a five-layer composite structure and comprises a film taped covering layer, an aluminum-plastic composited tape longitudinal covering shielding layer, a metal wire shielding layer, a zinc-coated steel wire armor layer and an outer protective sleeve layer from inside to outside sequentially, wherein the organic insulating layer is manufactured by polyether sulfone extruding-coating material, and the outer protective sleeve layer is made of a steel belt. The aviation cable has high-temperature resistance, good flame resistance, strong anti-jamming capability and practical applicability.

Description

A kind of Aviation cable

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of Aviation cable.

Background technology

In recent years, air transportation develops rapidly, constantly newly-built and expansion airport; Safeguard that thereupon the aviation safety facility also increases greatly; In various airport installations, see lighting apparatus such as plane track lamp, entering lamp from security standpoint; Vision auxiliary equipment as taking off and landing plays important effect.These distributions that throw light on use rubber mold transformer and the array mode of lighting a lamp, and the connection distribution of rubber mold transformer uses the special second third neoprene sheath high-tension cable that insulate usually.This cable-flame retardant property and radiation hardness interference free performance are poor, influence the quality of signal transmission.The accident that some airport takes place is because the fire resistance and the radiation hardness interference free performance difference of cable cause.

Summary of the invention

To the problem that above-mentioned prior art exists, the utility model provides a kind of Aviation cable, and it is high temperature resistant, and fire resistance is good, and antijamming capability is strong, and is very practical.

The technical scheme of the utility model is: a kind of Aviation cable; Comprise the protective sleeve that cable core is outer with being wrapped in cable core; Be provided with packed layer between protective sleeve and the cable core, said cable core constitutes by many insulated core is stranded, and said insulated wire cores is made up of the conductor insulating barrier outer with being wrapped in conductor; Said insulating barrier is four layers of composite construction; It is followed successively by from inside to outside: organic insulator, interior inorganic insulation layer, outer inorganic insulation layer and insulation screen, said protective sleeve are five layers of composite construction, and it is followed successively by from inside to outside: film lapping layer, aluminum plastic composite belt longitudinal bag screen, wire screen, zinc-coated wire armour and external sheath layer; Said organic insulator adopts polyether sulfone to extrude material and processes, and said external sheath layer adopts steel band to process.

As preferably, said packed layer is the alkali-free glass wool filler piece.

As preferably, said in inorganic insulation layer form by the mica band is wrapped, outer inorganic insulation layer forms by the alkali-free glass wool band is wrapped, insulation screen is a semiconductive ethylene-propylene rubber.

As preferably, said film lapping layer is processed for flame-proof glass fibre cloth.

As preferably, said wire screen is cancellated wire braid.

The beneficial effect of the utility model is: the utility model structural design is simple, and is scientific and reasonable, manufactures easily, and the outer insulating barrier of conductor adopts four layers of composite construction, and fire protecting performance is better, no any inflammable medium in the insulating barrier, and insulation property are good.Protective sleeve adopts five layers of composite construction, and the fire-proof insulation performance is better.Adopt the double layer screen layer of aluminum plastic composite belt longitudinal bag screen and wire screen, increased the interference free performance of cable.The wire screen not only can enhance protection the intensity of cover, and can improve the flexibility of the utility model, the convenient installation.The zinc-coated wire armour has strengthened the tensile property of the utility model, has improved anti-collision, shock resistance and the tensile property of the utility model.External sheath layer adopts steel band to process, and has further improved the intensity and the fire protecting performance of the utility model.Organic insulator adopts polyether sulfone materials, and it has avirulence, self-extinguishment, and not adding any fire retardant promptly has excellent flame retardancy, can reach UL94V-0 level (0.46mm).And hydrolysis can anti-150～160 ℃ of hot water or steam, the at high temperature also erosion of acid and alkali, alkali.This Aviation cable can be widely used in the airport installation construction, improves the particularly fail safe during takeoff and landing of airport, and excellent popularization using value and vast market prospect are arranged.
