The good high fire-resisting flexible cable of communication power supply high fire-retardance of effect.
Technical solution：To achieve the above object, the high fire-resisting flexible cable of communication power supply high fire-retardance of the invention is from inside to outside
Successively include tension cored wire, around the tension cored wire set the first conducting wire group being made of more first copper alloy wires,
Be set in the first flame-retardant layer on the outside of the first conducting wire group, around first flame-retardant layer set by more second copper alloy wires
The the second conducting wire group formed, the second flame-retardant layer for being set on the outside of the first conducting wire group and it is set on the outside of the second flame-retardant layer
Insulating boot.
Further, it is exhausted filled with first in the gap between the first copper alloy wire adjacent in the first conducting wire group
Edge body.
Further, it is exhausted filled with second in the gap between the second copper alloy wire adjacent in the second conducting wire group
Edge body.
Further, the tension cored wire is twisted by more aramid fiber cored wires.
Further, first flame-retardant layer is made of ceramic fire resistant silicon rubber.
Further, second flame-retardant layer by mica paper, the first glass-fiber-fabric being sticked on the inside of mica paper and is sticked to cloud
The second glass-fiber-fabric composition on the outside of female paper.
Further, the material of the insulating boot is low smoke halogen-free flame-retardant polyolefin.
Further, the first insulator is made of more glass fiber ropes.
Further, the second insulator is made of more glass fiber ropes.
Further, the metal net mask woven by aluminum-alloy wire is provided with the outside of tension cored wire.
Beneficial effect：The high fire-resisting flexible cable of communication power supply high fire-retardance of the present invention is ensureing outermost second flame-retardant layer
Internal conducting wire is divided into two groups while reliability, is respectively the first conducting wire group and the second conducting wire group, the first conducting wire group and the
The first flame-retardant layer is additionally provided between two conducting wire groups, the important level of conducting wire is thus divided into two groups, the first conducting wire group has dual
Insurance, in the case where outermost flame retardant coating is destroyed, the first conducting wire group may continue to work, can gain time, subtract for repairing
Few loss.
Brief description of the drawings
