Abstract
The utility model discloses a kind of high-strength waterproof fire-resisting cable, comprise the cable core consisting of cable core and strengthening core, described cable core consists of conductor, insulating barrier, inner sheath, screen and oversheath from inside to outside successively; Described strengthening core is from inside to outside successively by steel wire rope, protective layer and armour; The outermost oversheath of described cable core is connected by the outermost armour of plastic fastening and strengthening core.This construction of cable is simple, it is convenient to manufacture, production cost is low, and anti-wear performance is high, by the steel wire rope in oversheath outside, has strengthened the intensity of whole cable, has extended the useful life of cable; At the external one deck oversheath that adds of cable core, can well protect the structure of cable core, not fragile, further extended useful life of cable; This cable also has better water-and fire-proof performance.
Description
Technical field
The utility model belongs to power cable field, is specifically related to a kind of high-strength waterproof fire-resisting cable.
Background technology
As everyone knows, fire-retardant and the flame resistance of cable can be in use significance level, fireproof cable has in the past adopted the structures such as the mineral insulations such as magnesium oxide and metallic copper sheath, restriction due to each side, cause continuously big-length to be produced, and can not carry out bending, be not easy to mounting and installation, so there is flexible fire-proof cable, big-length is produced continuously by contrast, cross section is also unrestricted, there is good bending property simultaneously, mounting and installation is also very convenient, fire protecting performance is excellent, fire resistance rating not only meets the regulation in GB GB/T 19666-2005 and rower GA 306.2-2007, also can meet the 650 ℃ of 3h of A level that stipulate in Britain BS6387, 750 ℃ of 3h of B level, 950 ℃ of 3h of C level, the combustion requirements of 950 ℃ of 20min of S level, simultaneously, in burning, can tolerate water spray and mechanical impact.
At present, along with social development, the speed of designed for communications cables Cheng Genggao and transmission frequency, the isolation of insulation builds
Verified to be reduced to permission level be unsuccessful will crosstalk, and at least some known twistings are to comprising the isolation as shield member work to cable, and these interlayers comprise metal insert, and these metal inserts are enclosed in the insulating element of insulation.These traditional insulating elements are made and are assembled more expensive.In addition, these shielding interlayers keep relatively thick, thereby cause cable bulky, in staff is carrying out cable laying process, are easy to destroy outer jacket in laid processes.
In sum, the deficiency that prior art exists, flexible poor, water proofing property is poor, fire resistance is poor, in the use procedure of cable, easily by crooked and traction arbitrarily, easily causes disconnected core.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of flexible, water-and fire-proof is good, can be arbitrarily the high-strength cable of crooked and traction.
A kind of high-strength waterproof fire-resisting cable described in the utility model, comprises the cable core consisting of cable core and strengthening core, and described cable core consists of conductor, insulating barrier, inner sheath, screen and oversheath from inside to outside successively; Described strengthening core is from inside to outside successively by steel wire rope, protective layer and armour; The outermost oversheath of described cable core is connected by the outermost armour of plastic fastening and strengthening core.
Further improve, the gap of described cable core is provided with packed layer.
Further improve, the outermost layer of described cable core is provided with total oversheath.
Further improve, described insulating barrier consists of multi layer cloud master tape.
Further improve, described plastic fastening is polythene material, after heating, can be sticked together with oversheath and armour.
The beneficial effects of the utility model are:
Compared with prior art, this construction of cable is simple, it is convenient to manufacture, production cost is low, and anti-wear performance is high, by the steel wire rope in oversheath outside, has strengthened the intensity of whole cable, has extended the useful life of cable; At the external one deck oversheath that adds of cable core, can well protect the structure of cable core, not fragile, further extended cable useful life; This cable also has better water-and fire-proof performance.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of high-strength waterproof fire-resisting cable described in the utility model, comprises the cable core consisting of cable core and strengthening core, and described cable core consists of conductor 1, insulating barrier 2, inner sheath 3, screen 4 and oversheath 5 from inside to outside successively; Described strengthening core is from inside to outside successively by steel wire rope 7, protective layer 8 and armour 9; The outermost oversheath 5 of described cable core is connected with the outermost armour 9 of strengthening core by plastic fastening 6; The gap of described cable core is provided with packed layer 10; The outermost layer of whole cable is provided with total oversheath 11.
Described insulating barrier 2 consists of multi layer cloud master tape; Described plastic fastening 6 is polythene material, after heating, can be sticked together with oversheath 5 and armour 9.
The utility model provides a kind of high-strength waterproof fire-resisting cable; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
