Description

A kind of novel flame-retardant fireproof cable
Technical field
The invention belongs to technical field of cables, especially relate to a kind of novel flame-retardant fireproof cable.
Background technology
Fire-retardant fireproof cable is generally laid in Along Railway, connection device and machine room.In prior art, the structure of typical fire-retardant fireproof cable as shown in Figure 1, it be coated on the polyethylene inner sheath 6 of braiding copper cash outside by the insulated wire of parallel or stranded placement, the aluminum-plastic composite membrane 4 enveloped by insulated wire, the braiding copper cash 5 be positioned at outside aluminum-plastic composite membrane, extrusion molding, the double-deck galvanized steel strip 7 be coated on outside polyethylene inner sheath, extrusion molding are coated on polyethylene outside double-deck galvanized steel strip or halogen-free and low-smoke flame-retardant polyolefin oversheath 8 is formed; Insulated wire is made up of copper conductor 1, the polyethylene layer 2 that envelopes copper conductor; Tinned wird 3 to be positioned at outside insulated wire and simultaneously coated by aluminum-plastic composite membrane institute with insulated wire.Thunder and lightning or forceful electric power power transfer ratio are easier to cause stray electrical current; And railway mostly is strong electric traction, thus stray electrical current is more, comparatively large, easily cause and catch fire, burn, therefore, partial cables needs to be designed to flame retardant type; In addition, when cable is in machine room, also need to adopt fire resistive construction.
In prior art, for the cable of transferring electric power, except employing LSOH anti-flaming sheath, also adopt and on conductor, be wound around mica tape do insulating barrier or adopt inorganic mineral to do insulating barrier; To signal of communication series products, mostly protect on sheath, general employing LSOH anti-flaming oversheath, for insulation, because the electric capacity of signal of communication class cable needs cable pair is less, therefore insulating material generally adopts polyethylene or polyethylene foamed.Because polyethylene heatproof is lower, once there is electric discharge burning, the high temperature of generation can melt polyethylene layer very soon, causes short circuit, causes major safety risks to driving.
Publication No. is CN103903772A, name is called: a kind of fire-retardant fireproof cable, be made up of insulated power core, proof copper-wire braided screen, steel-tape armouring layer and silicone rubber jacket, described insulated power core is from inside to outside extruded in successively on three tinned copper wire stranded conductors by aluminium-plastic tape lapping layer and pe sheath to form, three tinned copper wire stranded conductors are arranged on carbon nano-fiber inner core, and insulated power core internal clearance has been partially filled flame resistant filler rope; Fire-retardant fireproof lapping layer extrudes three eradication edge power wire core and becomes cable core; Flame-retardant packed layer is provided with in described cable core internal clearance; Described cable core is from inside to outside extruded with proof copper-wire braided screen, steel-tape armouring layer and silicone rubber jacket successively.Its multi-layer fireproofing Principle And Method of Flame Retardation Design also can not solve the problem.
