Abstract
The utility model discloses a fireproof insulated shielded cable and relates to a cable, which comprises a cable core and a protective sleeve coating the cable core. A filling layer is arranged between the protective sleeve and the cable core. The cable core is formed by stranding two insulated wire cores. The insulated wire core comprises a conductor and an insulated layer coating the conductor. The insulated layer has a three-layer composite structure, that is, sequentially from inside to outside an organic insulated layer, an inorganic insulated layer and an insulated shielded layer. The protective sleeve has a three-layer composite structure, that is, sequentially from inside to outside a lining layer, a metal wire shielded layer and an outer sheath layer. The organic insulated layer is made of a polyether sulfone extruded material. The outer sheath layer is a corrugated stainless steel pipe. The fireproof insulated shielding cable has the advantages of high temperature resistance, acid and alkali erosion resistance, good flame retardant performance, strong anti-interference ability and strong practicability.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of fire-proof insulation shielded type cable.
Background technology
In recent years, air transportation develops rapidly, continuous newly-built and expansion airport, safeguard that thereupon the aviation safety facility also increases greatly, in various airport installations, from security standpoint, the plane track lamp, enter the lighting apparatus such as lamp, vision auxiliary equipment as taking off and landing plays very 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 special second the third insulation neoprene sheath high-tension cable usually.This cable-flame retardant and radiation hardness interference free performance are poor, affect the quality of signal transmission.The accident that some airports occurs is because the fire resistance of cable and the radiation hardness interference free performance is poor causes.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of fire-proof insulation shielded type cable, and it is both high temperature resistant, and acid and alkali-resistance corrodes again, and fire resistance is good, and antijamming capability is strong, and is very practical.
The technical solution of the utility model is: a kind of fire-proof insulation shielded type cable, comprise cable core and be wrapped in the outer protective sleeve of cable core, be provided with packed layer between protective sleeve and the cable core, described cable core thoroughly does away with by two that the edge core is stranded to be consisted of, described insulated wire cores is made of the conductor insulating barrier outer with being wrapped in conductor, described insulating barrier is three-layer composite structure, it is followed successively by from inside to outside: organic insulator, inorganic insulation layer and insulation screen, described protective sleeve is three-layer composite structure, and it is followed successively by from inside to outside: inner covering, metal wire shielding layer and external sheath layer; Described organic insulator adopts polyether sulfone to extrude material and makes, and described external sheath layer is corrugated stainless steel.
As preferably, described packed layer is the alkali-free glass wool filler piece.
As preferably, described inorganic insulation layer forms by the alkali-free glass wool band is wrapped, and insulation screen is semiconductive ethylene-propylene rubber.
As preferably, described inner covering is the flame-proof glass fibre layer of cloth.
As preferably, described metal wire shielding layer is cancellated wire braid.
The beneficial effects of the utility model are: the utility model structural design is simple, and is scientific and reasonable, manufactures easily, and the outer insulating barrier of conductor adopts three-layer composite structure, and fire protecting performance is better, and without any inflammable medium, insulation property are good in the insulating barrier.Protective sleeve adopts three-layer composite structure, and the fire-proof insulation performance is better.Adopt metal wire shielding layer, increased the interference free performance of cable.External sheath layer is corrugated stainless steel, has improved anti-collision of the present utility model, shock resistance, tensile property, and has further improved intensity of the present utility model and fire protecting performance.Organic insulator adopts polyether sulfone materials, and it has avirulence, self-extinguishment, and not adding any fire retardant namely 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 good application value and wide market prospects are arranged.
