Abstract
The utility model relates to a special cable. The utility model is characterized in that comprises multi-core cables, wherein a power supply wire flame resistant insulation layer (3), a steel strip layer (2) and an outer surface insulation layer (1) are orderly covered on the multi-core cables; each cable comprises power supply wires and an outer insulation surface layer (4). The utility model is characterized in that a plurality of signal wires in the power supply wire flame resistant insulation layer (3) are parallel with the multi-core cables; each signal wire comprises conducting wires (10) and an insulation layer (8). The utility model has the advantages that because signal transmission wires and the power supply wires are combined together, the utility model can complete installation and construction at one time, does not need laying in a wire distributing manner, reduces construction quantities, lowers the total cost and avoids influencing the regular production by interrupting the signal wires in the course of the operation.
Description
One, technical field: the utility model relates to a kind of cable, especially a kind of private cable line.
Two, background technology: electromechanics combines with the height of automation at present, requires supply of electric power and control realization synchronously automatically, and original cable comprises outer surface insulating barrier, steel belt layer, power line flame retardant insulation and multicore cable composition, only has single power supply function.When electrical equipment is controlled, need to use in addition control signal wire, certainly will increase workload like this.The tensile strength and the safeguard procedures of synchronous signal line are simple, often occur in use damaging, and influence ordinary production.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of private cable line is provided.
Its technical scheme is: comprise the multicore cable that outer surface insulating barrier (1), steel belt layer (2), power line flame retardant insulation (3) coat, every cable comprises power line (6) and external insulation top layer (4), it is characterized in that: with multicore cable is parallel many holding wires are arranged in power line flame retardant insulation (3), every holding wire comprises lead (10) and insulating barrier (8).
Wherein, the skin at holding wire is coated with holding wire metal screen layer (7) and holding wire appearance insulating barrier (5).
More preferably in power line flame retardant insulation (3) with the parallel filling tape (9) that is provided with of multicore cable and holding wire.
Beneficial effect is: because the utility model adopts signal transmssion line and power line are lumped together, installation once can be finished, and does not need separated time to assist and establishes, and has significantly reduced construction volume, reduced total cost again, avoided holding wire to interrupt in the use and influence ordinary production.
Four, description of drawings:
Accompanying drawing is the cutaway view of embodiment of the present utility model.
Among the figure: 1, single core insulation layer 9, filling tape 10, signal conductor in cable outer surface insulating barrier 2, steel belt layer 3, insulating barrier 4, power line flame retardant insulation 5, holding wire appearance insulating barrier 6, power line conductor 7, holding wire metal screen layer 8, the holding wire.
Five, embodiment:
With reference to accompanying drawing, the utility model will be further described:
To have the signal transmssion line of metal screen layer and the power line of needs and lump together, be combined into the private cable line that a kind of existing power power-line has signal transmssion line again.In order to better meet the demand of electric heater, signal transmssion line is not subjected to Electromagnetic Interference, holding wire has screen, power line is for improving the life-span of heatproof degree prolongation terminals, the power line insulating barrier adopts flame retardant insulation, has stretching resistance filling tape or steel belt layer to increase the mechanical strength of cable simultaneously.Specific as follows: holding wire comprises that by several signal conductor 10 and insulating barrier 8 form, and is coated with holding wire metal screen layer 7 and holding wire appearance insulating barrier 5 in the outside of holding wire.Every cable comprises power line conductor 6 and the fire-retardant logical edge layer 4 of power line, is coated in insulating barrier 3, steel belt layer 2 and the cable outer surface insulating barrier 1 with holding wire is parallel.In order to increase the tensile strength of cable, in power line flame retardant insulation 3 with multicore cable and the parallel filling tape 9 that is provided with of holding wire.
The radical of cable and holding wire disposes as required, presses the auxilliary good cable of actual range during use, and power line is connected convenience, saving of labor, safety with holding wire difference electrical equipment with control circuit.
