A kind of light-duty high fire-retardance Double colour double-deck cable, including be arranged according to this from inside to outside internal core, double layer of insulation
And oversheath；The internal core is made of transmission core, resilient barrier frame, flame resistant filler rope and band；The transmission core
It is provided with three groups, it is evenly spaced by resilient barrier frame between three groups of transmission cores；The transmission core includes that aluminium wire is led
In the thin copper wire of aluminium wire conductor periphery, the thin copper wire is unidirectionally wound around on aluminium wire conductor, described every for body and tight
It is provided with two flame resistant filler ropes outside group transmission core；The internal core periphery is coated with one layer of band；The inner wire
Core is coated with double layer of insulation；The double layer of insulation includes the first insulating layer and second insulating layer；First insulation
Layer is coated on belting layer；The second insulating layer cladding is on the first insulating layer；First insulating layer is monochromatic insulating layer,
The second insulating layer is the colorful insulation layer for including two kinds of colors, is set in the second insulating layer interior there are four same color
Insulator, the bar shaped tongue being axially distributed along cable is equipped in the side of the interior insulation body, and four of another color are exhausted outside
Edge body is respectively placed in four bar shaped tongues；It is additionally provided with oversheath outside the second insulating layer.
Further, first insulating layer uses cross-linking polyethylene materials, the second insulating layer to use low smoke and zero halogen
Crosslinked polyolefin materials.
Further, the resilient barrier frame is made of stainless steel strip.
Further, the band is fire-resistant isinglass belt or Halogen band.
Further, the oversheath is made of cross-linked polyolefin high molecular material.
Compared with prior art, the utility model has the beneficial effects that：The utility model construction of cable is simple, mechanical performance
Well, by using the double-layer structure of monochromatic inner insulating layer and colored external insulation layer, both reached the antifalse effect of colored cable,
The content of colorful insulation layer can be reduced again, and with the lower monochromatic insulating layer supplement of price, to reduce manufacturing cost, and more
Add environmental protection；Internal core is separated using resilient barrier frame by core is transmitted simultaneously, and adds flame resistant filler rope, then using packet
With wrapped, while greatly increasing anti-torsion, the bending property of cable in this way, fire-retardant fireproof, heat-resisting, anti-aging property are also more
It is excellent and strong with bearing capacity, long lifespan.
