Abstract
The utility model discloses a flame-retardant multifunctional composite cable. The composite cable comprises a plurality of signal cable insulated wire cores and a plurality of power cable insulated wire cores, wherein the plurality of signal cable insulated wire cores are concentrically stranded to form a shielded cable core; a first packing layer is filled in the gap in the shielded cable core; the shielded cable core is concentrically stranded with the plurality of power cable insulated wire cores to form a cable core after being concentrically wound with a first belting layer and a first shielding layer outside the shielded cable core in sequence; and a second packing layer is filled in the gap in the cable core; and a second belting layer, a second shielding layer, an isolating layer, a metal belting layer and a sheathing layer are concentrically wound outside the cable core in sequence. In the utility model, power cables and signal cables are combined into a cable, so that electrical energy and signals can be transmitted by the same cable, and the cable serves a function of shielding the interference of electromagnetic induction generated by electrified current and has flame retardant property.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of flame-retardant multifunctional composite cable.
Background technology
In recent years, country vigorously advocates to conservation-minded society development, from the national grid to the factory, the layout of electric wire cable for building, is also improving towards compact, economizing type.Yet the signal of some equipment, monitoring loop are not only the transmission of signal at present, need a power cable to realize the transmission of electric energy toward contact, and the electromagnetic interference of cable electric current generation when also requiring can suppress to switch on.If lay two kinds of cables respectively, not only time-consuming taking a lot of work installed and to be taken up room greatly, and cost and later maintenance expense all can remain high, and is difficult to satisfy the requirement of building a conservation-minded society.
The utility model content
The technical problems to be solved in the utility model provides a kind ofly organically to be combined power cable core and signal cable core, and put screen at combination cable core peripheral hardware, realize that a cable can transmission of electric energy, can realize the signal transmission again, and play the flame-retardant multifunctional composite cable of shielding interference effect.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of flame-retardant multifunctional composite cable, comprise signal cable insulated wire cores and power cable insulation core, some signal cable insulated wire cores are twisted with one heart and are made the shielding cable core, space in the shielding cable core is filled with first packed layer, the shielding cable core twines first belting layer outward successively with one heart, first screen, make cable core with the some concentric strands of power cable insulation core again, space in the described cable core is filled with second packed layer, and described cable core is wound with second belting layer outward successively with one heart, the secondary shielding layer, separator, steel belt layer and restrictive coating.
Cable core described in the utility model adopts the strand system core structure of 2 cores+multicore, 3 cores+multicore, 4 cores+multicore, 5 cores+multicore to form by power cable insulation core and signal cable insulation shielding core.
Signal cable insulated wire cores described in the utility model and power cable insulation core are coated with retardant plastic insulation layer.
First, second belting layer described in the utility model and first, second packed layer are the fire proofing layer.
First, second screen described in the utility model is for twining copper strips screen or braiding copper wire screen.
Separator described in the utility model is for extruding the flame retardant plastics layer.
Steel belt layer described in the utility model is a double-deck galvanized steel strip gap winding arrangement, and its gap is not more than 50% of bandwidth.
Restrictive coating described in the utility model is for extruding the flame retardant plastics layer.
The utility model compared with prior art, Stability Analysis of Structures, compactness, overall dimension is less, power cable and signal cable are combined into a cable, realized that same cable can transmission of electric energy, can carry out the transmission of signal again, cable also plays the effect of the electromagnetic induction interference of shielding electrical current generation simultaneously, and cable has fire resistance.Because power cable and signal cable are combined, two independent relatively cables have been saved shielding, armouring and sheath material, have reduced the manufacturing cost of product, have reduced repeating when cable is installed and have connected up the wiring space of having saved cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, be an embodiment of the utility model flame-retardant multifunctional composite cable, mainly comprise signal cable insulated wire cores 2 and power cable insulation core 1 among this embodiment, at first twist with one heart and make the shielding cable core by three signal cable insulated wire cores 2, space in the shielding cable core is filled with first packed layer 3, the shielding cable core twines first belting layer 4 and first screen 5 outward successively with one heart, make cable core with three power cable insulation cores, 1 concentric strand again, space in the described cable core is filled with second packed layer 6, and described cable core is wound with second belting layer 7 outward successively with one heart, secondary shielding layer 8, separator 9, steel belt layer 10 and restrictive coating 11.
In the utility model cable core, power cable insulation core 2 and signal cable insulated wire cores 1 the shielding cable core of strand system with one heart can adopt the strand system core structure of 2 cores+multicore, 3 cores+multicore, 4 cores+multicore, 5 cores+multicore to form.Signal cable insulated wire cores 2 and power cable insulation core 1 adopt retardant plastic insulation layer to coat.Belting layer and packed layer are the fire proofing layer.Screen 5 is for twining copper strips screen or braiding copper wire screen.Separator 6 is for extruding the environmental protection flame retardant plastic layer.Steel belt layer 7 is a double-deck galvanized steel strip gap winding arrangement, and its gap is not more than 50% of bandwidth.Restrictive coating 8 is for extruding the flame retardant plastics layer, its oxygen index＞35%.
The utility model is realized the branch shielding outside the signal cable cable core, realize total shielding with the combination cable core outside of power cable again, make power cable and signal cable can both suppress the electromagnetic induction interference that electrical current produces, and combination cable has fire resistance, is applicable to the place that precision electronic device is concentrated.
The utility model provides a kind of thinking and implementation method of flame-retardant multifunctional composite cable; concrete application approach is a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
