It sets, convenient for effectively avoiding cable run, in case damage cable, is also prevented from and is hindered by impaired cable, more to the inspection under dark surrounds
Repair, repair and safeguard etc. that related works provide a convenient；High intensity, transmission capacity is big, and service life is long, saves a large amount of shaft towers,
And shorten the construction period, greatly save sapce charge, human cost；After combustion cable jacket sinter into ceramic hard shell and
It does not melt under fire (950~1300 DEG C) environment, drip, and be resistant to certain external impacts, to ensure cable
It remains to work normally in case of fire, and there is good soft pliable song under the Novel firefighting fire-resisting cable normality
Can, simple production process need not increase dedicated equipment, be a kind of fire resistance more preferably product, be expected to the crowd from now on
More high requests, high standard engineering project in find broad application.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of fire-fighting distribution line high stable fire safe type power cable, including support frame of conductor 1, it is described
Support frame of conductor on be provided with multiple arcs slot, it is corresponding in each arc groove to be equipped with insulated fireproof core, be combined into cable core；Institute
The insulated fireproof core stated is by conductor 2, the polyethylene layer being extruded in outside conductor 3 and is extruded in outside polyethylene layer
Carbon fiber flame-retardant layer 4 is constituted；It is equipped with low smoke and zero halogen polyethylene anti-flaming filled layer or composite material of silicon carbide in the gap of cable core
Filled layer 5, metal wire knitted shielded layer 6 is externally provided in cable core, flame retardant coating 7 is externally provided in metal wire knitted shielded layer, in fire resisting
