Abstract
The utility model relates to a fire -resistant control cable that blocks water, including cable unit, second filling layer and second protective layer, the cable unit includes conductor wire, conductor wire 's cross -section is regular polygon, conductor wire includes conductor core and copper coating, conductor wire in close contact with of each other forms the conductor and restraints, the conductor is restrainted the surface and is first filling layer, first filling layer surface is the insulating layer, the insulating layer surface is fire -retardant layer, fire -retardant layer surface is first protective layer, the second filling layer is located between the cable unit, the second protective layer is located second filling layer surface. The utility model discloses a coppered steel wire that utilizes regular polygon is as the core, has strengthened the intensity of the whole core of cable for the cable is non -deformable under the rainwater weather condition, and the rethread increases the fire -retardant water proof material of first protective layer and second protective layer, makes the cable wholeness stably to be particularly suitable for the more area use of china's rainwater.
Description
Technical field
This utility model belongs to field of cables, is specifically related to a kind of fire-resistant watertight control cable.
Background technology
China much areas are many due to rainwater, and existing cable is easier to be deformed by rain drop erosion, deformation of i.e. making moist, cause cable to consolidate poor performance, cable interior waterproof is deteriorated, as met the harsh conditions such as fire, under these conditions, fire resistance is the most seriously affected existing cable.
Utility model content
For above-mentioned problem of the prior art and non-foot point, this utility model provides a kind of fire-resistant watertight control cable, and cable core intensity increases, and firm performance is good, and fire-resistant blocks water.
For solving the problems referred to above, adopted the technical scheme that:
A kind of fire-resistant watertight control cable; including cable unit, the second packed layer and the second protective layer; described cable unit includes conductor silk; the cross section of described conductor silk is regular polygon, and described conductor silk includes that conductor cores and copper coating, described conductor silk are brought into tight contact with each other formation conductor bundle; described conductor bundle outer surface is the first packed layer; described first packed layer outer surface is insulating barrier, and described insulating barrier outer surface is flame-retardant layer, and described flame-retardant layer outer surface is the first protective layer；Described second packed layer is between described cable unit, and described second protective layer is positioned at described second packed layer outer surface.
Preferably, the thickness range of described copper coating is 0.1mm to 0.8mm.
Preferably, the one during the cross section of described conductor silk can also be square, regular pentagon or regular hexagon.
Preferably, the material of described first packed layer is glass cord.
Preferably, the material of described insulating barrier is polrvinyl chloride.
Preferably, the material of described first protective layer is polrvinyl chloride.
Preferably, described second protective layer is water blocking tape layer.
Use technique scheme, acquired provide the benefit that:
Fire-resistant watertight control cable in this utility model; by utilizing the coppered steel wire of regular polygon as core body; enhance the intensity of cable entirety core; cable is unlikely to deform under rainwater weather condition; again by increasing the fire-retardant water proof material of the first protective layer and the second protective layer; make cable overall performance stable, be particularly suitable for the area use that China's rainwater is more.
Accompanying drawing explanation
Fig. 1 is the structural representation of fire-resistant watertight control cable of the present utility model.
Fig. 2 is the structural representation of conductor silk in this utility model.
Sequence number in figure: 1 conductor silk, 11 conductor cores, 12 copper coatings, 2 first packed layers, 3 insulating barriers, 4 flame-retardant layers, 5 first protective layers, 6 second packed layers, 7 second protective layers.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, this utility model is further described, but this utility model is not limited to these embodiments.
Embodiment 1
As shown in Figures 1 and 2, the fire-resistant watertight control cable of one that the utility model proposes, including cable unit, second packed layer and the second protective layer, described cable unit includes conductor silk 1, described conductor silk 1 includes conductor cores 11 and copper coating 12, the thickness of copper coating is 0.2mm, described conductor silk 1 is brought into tight contact with each other formation conductor bundle, described conductor bundle outer surface is the first packed layer 2, the material of described first packed layer is glass cord, described first packed layer 2 outer surface is insulating barrier 3, the material of described insulating barrier is polrvinyl chloride, described insulating barrier 3 outer surface is flame-retardant layer 4, described flame-retardant layer 4 outer surface is the first protective layer 5, the material of described first protective layer 5 is polrvinyl chloride；Described second packed layer 6 is between described cable unit, and described second protective layer 7 is positioned at described second packed layer 6 outer surface, and described second protective layer is water blocking tape layer.
This utility model is not limited to above-mentioned detailed description of the invention, and those skilled in the art also can make multiple change accordingly, but any all should contain in the range of this utility model claim with this utility model equivalent or similar change.
