Abstract
The utility model discloses a high-flame-retardant double-shielded silicone rubber cable. The cable comprises several cabling cores. The cable is characterized in that the cable comprises the several cabling cores; each cabling core comprises a conductor and a high-performance nanoscale carbon fiber fire prevention silicone rubber insulation layer outside the conductor; a composite shielding layer wraps the silicone rubber insulation layer; the composite shielding layer is formed by a nanoscale carbon fiber fire prevention silicone rubber inner layer and a high-performance carbon fiber shielding outer layer; a sensing fiber is arranged between the nanoscale carbon fiber fire prevention silicone rubber inner layer and the high-performance carbon fiber shielding outer layer along a vertical direction of the cable. Compared to the prior art, by using the cable of the utility model, a plurality of nickel plating soft copper wires are intertwisted along a same direction and form a conductor so as to be served as a core; the cable is easy to be bent and an environment adaptability is high; simultaneously through arranging the sensing fiber in the composite shielding layer, accurate monitoring is performed on the cable; when the sensing fiber is fractured, a fracture position can be timely found out; an accident can be prevented and usage is safe.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of high flame retardant double shield silicone rubber for cable.
Background technology
Develop rapidly along with China's industry, the sharp increase of urban population, the continuous increase of skyscraper, hotel, hotel, large hospital, station, airport, subway and large-scale public place of entertainment, public transit facility, it is very outstanding that security against fire also seems, how in the situation that breaking out of fire, can ensure to greatest extent the unimpeded of electric power and communication line, for people win the quality time of escape and the loss that reduces property to greatest extent, become problem demanding prompt solution.And nowadays plastic insulated cable constantly increases in the industrial scope of application and consumption, common plastics insulated cable anti-flammability is poor, and after adding fire retardant, electrical insulating property reduces, and when burning produce a large amount of poisonous and harmful smog, environment, personnel and equipment have all been produced to great harm.Chinese patent CN201220591960.6 discloses a kind of nanoscale environment protection high flame resistance silicone rubber for cable, this cable comprises some insulated wire cores, insulating barrier, composite shielding layer and outer jacket, described core is by regular stranded the forming of the thin copper wire multiply with corrosion-resistant anti-oxidant coating, and adopted the metal structure extrusion process, make conductor Paint Gloss; Described core is coated with insulating barrier; Described insulating barrier consists of high-performance nano grade carbon fiber fireproof silicone rubber insulating material; Described insulating barrier is coated with composite shielding layer, and described composite shielding layer is that the high-performance carbon fibre fire prevention strengthens coating layer, nano-scale carbon fiber fireproof silicone rubber internal layer and high-performance carbon fibre screen from inside to outside successively; Described composite shielding layer is coated with outer jacket, and described outer jacket consists of carbon fiber fireproof silicone rubber material.Its advantage is easy bending, and mechanical strength is high, and waterproof, protection against the tide, anti-chemical corrosivity strengthen.In a single day but also there is an obviously deficiency, namely use the life-span to fall short of, and break down, be difficult to detect timely and accurately the cable damaged location, be difficult for changing and maintenance.In addition, heat-proof quality is not good yet.
The utility model content
The purpose of this utility model is to provide a kind of high flame retardant double shield silicone rubber for cable of new construction, and by architecture advances, not only fire resistance is better, shielding properties is better, and, when the faults such as the disconnected core of cable generation, the cable damaged location can be detected timely and accurately, easy to replace and maintain.
For realizing this purpose, the technical solution of the utility model is: a kind of high flame retardant double shield silicone rubber for cable, comprise some one-tenth cable cores, described one-tenth cable core comprises conductor and the outer high-performance nano grade carbon fiber fireproof silicone rubber insulating barrier of conductor, described silicone rubber insulation layer is coated with composite shielding layer, described composite shielding layer is comprised of nano-scale carbon fiber fireproof silicone rubber internal layer and high-performance carbon fibre shield external layer, the sensing fiber that arranges along the vertical aspect of cable between described nano-scale carbon fiber fireproof silicone rubber internal layer and high-performance carbon fibre shield external layer.
As preferably, described conductor is by multiply nickel plating soft copper silk stranded forming in the same way.
As preferably, outside described composite shielding layer, be coated with by the wrapped thermal insulation layer that forms of some polymethyl methacrylate silk ribbons.
As preferably, described thermal insulation layer is coated with by the wrapped heat insulation reinforced layer that forms of some high temperature resistant stainless steel alloy silk ribbons.
With respect to prior art, it is core that the utility model adopts the stranded in the same way conductor that forms of multiply nickel plating soft copper silk on the one hand, easily crooked, the adaptability of environment is high, nano-scale carbon fibrillatable fireproof silicone rubber material outer jacket has improved the mechanical strength of cable, waterproof, protection against the tide, anti-chemical corrosivity strengthen, and have extended the useful life of cable.Built-in sensing fiber in composite shielding layer, can monitor accurately to cable on the other hand, when sensing fibrous fracture, can clearly find fracture position, tries to avert accidents, and uses safer.The thermal insulation layer that arranges simultaneously and heat insulation reinforced layer play a very good protection when the breaking out of fire to cable.
The accompanying drawing explanation
Fig. 1 is the utility model cross-sectional view.
Wherein: 1, copper conductor; 2, insulating barrier; 3, silicon rubber internal layer; 4, shield external layer; 5, thermal insulation layer; 6. sensing fiber.
Embodiment
In conjunction with the embodiments the utility model is further illustrated with reference to the accompanying drawings.
As shown in Figure 1, a kind of high flame retardant double shield silicone rubber for cable, comprise some one-tenth cable cores, described one-tenth cable core comprises conductor and the outer high-performance nano grade carbon fiber fireproof silicone rubber insulating barrier of conductor, described silicone rubber insulation layer is coated with composite shielding layer, described composite shielding layer is comprised of nano-scale carbon fiber fireproof silicone rubber internal layer and high-performance carbon fibre shield external layer, the sensing fiber that arranges along the vertical aspect of cable between described nano-scale carbon fiber fireproof silicone rubber internal layer and high-performance carbon fibre shield external layer.Wherein, described conductor is by multiply nickel plating soft copper silk stranded forming in the same way.
In order to increase heat insulating effect, the described coated insulation layer outside is coated with by the wrapped thermal insulation layer that forms of some polymethyl methacrylate silk ribbons, and described thermal insulation layer is coated with by the wrapped heat insulation reinforced layer that forms of some high temperature resistant stainless steel alloy silk ribbons.
