Abstract
The utility model discloses a kind of wisdom and hand over general shield drainage locomotive cable, comprise from the inside to the outside: cable core, twining package tape, total screen and oversheath; Described cable core comprises at least one insulated wire cores, a drainage thread and is filled in insulated wire cores, packed layer between drainage thread and twining package tape; Described drainage thread is that tinned copper wire is restrainted strand in the same way and formed.The utility model can transferring electric power and signal, and drainage thread effectively can dredge the charge inducing of screen, guarantees to work alone in wisdom traffic system not by outside electromagnetic interference, effectively raises the precision of signal controlling.
Description
Technical field
The utility model relates to wisdom and hands over general shield drainage locomotive cable.
Background technology
Along with the development of wisdom traffic system, hand over the requirement of the environment for use of universal cordage and performance more and more higher to wisdom.Require, under the prerequisite ensureing cable serviceability, to reduce the insulation thickness of cable and the diameter of conductor as much as possible, improve heatproof, oil resistant, rub resistance, resistance to environmental rating, require that insulating material has the environmental friendliness performances such as low-smoke non-halogen flame-retardant simultaneously.Along with the space of the wisdom vehicles reduces gradually, the structure of cable is more and more compacter, and the working space of core of a cable is also more and more less, and Signal transmissions class cable to each other distance is very little, and existing cable structure can not meet this requirement.
Utility model content
The purpose of this utility model is to provide wisdom and hands over general shield drainage locomotive cable.
Realizing this uses the technical scheme of novel object to be that a kind of wisdom hands over general shield drainage locomotive cable, comprises from the inside to the outside: cable core, twining package tape, total screen and oversheath; Described cable core comprises at least one insulated wire cores, a drainage thread and is filled in insulated wire cores, packed layer between drainage thread and twining package tape; Described drainage thread is that tinned copper wire is restrainted strand in the same way and formed.
Described insulated wire cores is followed successively by conductor, insulating barrier and insulation screen from the inside to the outside; Described conductor is that tinned copper wire is stranded in the same way.
Described insulated wire cores and drainage thread contact with each other.
Described insulation screen is aluminium-plastic tape double layer screen.
Described total screen is copper wire establishment shielding.
Adopt technique scheme, the utility model has following beneficial effect: the construction of cable of the present utility model is compact, pliability is good, fire resistance is high, possesses on-line monitoring cable real-time working temperature feature, effectively raises cable work safe class.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is the structural representation of the utility model multicore cable.
Attached number in the figure is:
Cable core 1, insulated wire cores 11, conductor 11-1, insulating barrier 11-2, insulation screen 11-3, drainage thread 12, packed layer 13, twining package tape 2, total screen 3, oversheath 4.
Embodiment
(embodiment 1)
See Fig. 1, wisdom hands over general shield drainage locomotive cable, comprises from the inside to the outside: cable core 1, twining package tape 2, total screen 3 and oversheath 4; Described cable core 1 comprises two insulated wire cores, 11, drainage thread 12 and is filled in insulated wire cores 11, packed layer 13 between drainage thread 12 and twining package tape 2; Described drainage thread 12 forms for strand restrainted in the same way by tinned copper wire.Described insulated wire cores 11 is followed successively by conductor 11-1, insulating barrier 11-2 and insulation screen 11-3 from the inside to the outside; Described conductor 11-1 is that tinned copper wire is stranded in the same way.Described insulated wire cores 11 and drainage thread 12 contact with each other.Described insulation screen 11-3 is aluminium-plastic tape double layer screen.Described total screen 3 is copper wire establishment shielding.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the above MV shielded cable is only specific embodiment of the utility model representative; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
