Layer, water blocking layer, flame-retardant layer pass sequentially through adhesive and are connected with water barrier, and the flame-retardant layer is fire-retardant fiber band, in substrate layer
On offer densely covered micropore.
The utility model is using the above-mentioned technical solution beneficial effect to be reached：Using waterproofing type conductor,
Adding water blocking yarn during stranded compact conductor can effectively strengthen conductor water-resisting ability；Using the cable core of fire-retardant waterproofing type, cable core into
In cable technique, waterproofing rope and wrapped waterstop are filled so that the cable has fire-retardant and fire resistance simultaneously, can effectively prevent
Accelerate insulation ag(e)ing because the factors such as moist, immersion produce water tree and electricity tree with cable is reduced, the insulaion resistance for causing declines, electricity
Cable punctures and the loss caused by initiation fire；New Ceramic silicon rubber layer is applied to into the flame retardant coating or insulating barrier of cable
When, not only with wrapped, and bag can be indulged, processing technology is simplified, cost can be greatly lowered, and, ceramic SiClx
Rubber layer has good flexibility and elasticity, the characteristic for possessing usual silicone rubber, can be at 350～3000 DEG C, flame 3min
Under the ablation time above, the ablated housing for changing into ceramic-like forms one layer of hard protective layer, plays the extraneous fire of isolation
The effect of flame, so as to protect the object for being burnt without damage；The waterstop of the cable has anti-flammability while blocking water, and removes from
The trouble of how wrapped one layer of inhibiting tape is needed again during actual production, production stage is effectively simplified；Using with anti-flammability
Adhesive, further increases the water preventing ability of waterstop.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in Figure 1, one kind blocks water fireproof power cable, it include cable core 1, waterproofing rope 2, waterstop, sheath 4,
