Specific embodiment
Embodiment:Referring to Fig. 1, a kind of overload-alarm power cable, including cable core, the cable core includes some heart yearns, The heart yearn includes conductor 2, the outer wrapping insulating barrier 3 of the conductor 2;Protective layer is wrapped in outside the cable core, the protective layer by Inside there is belting layer 5 and outer jacket 6 outward;Obturator 4 is filled between the cable core and the protective layer;The cable core it Between four core analog quantity temp.-determined type temperature sensing cables 1 are set, the four cores analog quantity temp.-determined type temperature sensing cable 1 is along the cable core axis Direction extends, and end and detector(Controller)Connection.
In the present embodiment, the detector is connected to warning device and/or cable power roof-cut resistence.
In the present embodiment, the cable core has three, four, five heart yearns, and the heart yearn is distributed in triangle disposition, described Four core analog quantity temp.-determined type temperature sensing cables are arranged on cable core middle part.
In the present embodiment, the conductor uses compacting pressing conductor(Annealing compacting pressing conductor)It is made.
In the present embodiment, the obturator is fireproof glass silk fiber.
In the present embodiment, the belting layer is made of glass fiber band.
In the present embodiment, the outer jacket is made of low-smoke halogen-free environment high polymer.
The temperature module uses four core analog quantity temp.-determined type temperature sensing cables, is made up of four cores, during temperature change, four cores Lead line resistance to change, when resistance variations reach the alarm threshold value of setting, detector sends fire alarm signal or cuts Power-off source.
Using annealing compacting pressing conductor as cable core conductor.
The outer extruded insulation layer of conductor, three cores are divided into red, yellow, and green, and four cores are divided into red, yellow, and green, orchid.Ground connection core color is Black.
Fireproof glass silk fiber filling rounding is placed during stranding.
While wrapped one layer of glass fiber band.
Extrude outer jacket of the one layer of low-smoke halogen-free environment high polymer as cable.
In addition, referring to Fig. 2, protective layer outer surface(That is the outer surface of outer jacket 6)Along cable length direction spaced set Several rectangular tag slots 61, the tag slot surface is coated with luminescent coating.The interval wire that sets of two adjacent marks connects Binding structure 62, graduation mark is set in the attachment structure.Due to be provided with the tag slot with luminescent coating, therefore cable resolution compared with Height, especially for rather dark environment, improves the security of cable, because tag slot is equally spaced, when cable is locally by outer After power stretching, it is easy to recognize the place that is stretched, after block design graduation mark is identified, resolution is higher.
