Abstract
Disclosed in the utility model is a fire-proof insulated shielding cable. The cable comprises a cable core and a protection sleeve coating the outside of the cable core; and a filling layer is arranged between the protection sleeve and the cable core. The cable core is formed by twisting of two insulated wire cores including conductors and insulated layers coating the outsides of the conductors; and the insulated layers have three-layer composite structures that is characterized in that organic insulated layers, inorganic insulated layers and insulated shielding layers are successively arranged from inside to outside. The protection sleeve has a four-layer composite structure that is characterized in that an inner fire-proof layer, an outer fire-proof layer, a metal filament shielding layer and an outer sheath layer are successively arranged from inside to outside. The filling layer is an inorganic fire-proof expansion layer; the organic insulated layers are made from polyether sulfone extruding materials; the inner fire-proof layer is a ceramic silicon rubber layer; and the outer fire-proof layer is a crusting polyolefin layer. The provided fire-proof insulated shielding cable has the advantages of high temperature resistance, acid-alkali erosion resistance, good flame retardant performance, excellent anti-interference property, and high 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 due to the fire resistance of cable with 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 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 four layers of composite construction, it is followed successively by from inside to outside: interior flame retardant coating, outer flame retardant coating, metal wire shielding layer and external sheath layer, described packed layer is inorganic fire-resistant expanding layer, and described organic insulator adopts polyether sulfone to extrude material and makes, and described interior flame retardant coating is the ceramic silastic-layer, and described outer flame retardant coating is crust type polyolefin layer.
As preferably, described external sheath layer is corrugated stainless steel.
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 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 in insulating barrier, without any inflammable medium, insulation property are good.Protective sleeve adopts four layers of composite construction, and the fire-proof insulation performance is better.Adopt metal wire shielding layer, increased the interference free performance of cable.Packed layer is inorganic fire-resistant expanding layer, and after cable was met fire, inorganic fire-resistant expanding layer produced to expand and compresses, the effectively isolated temperature that reduces.The interior flame retardant coating that ceramic silicon rubber consists of, under burning condition, change the refractory heat-insulating structure of similar ceramic-like solid refractory heat-insulating cover when meeting high temperature into, crust type polyolefin crust performance is good, make outer flame retardant coating under burning condition, meet fire and crust, interior flame retardant coating is tightly wrapped up, have good in the effect of itching.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.
