Abstract
The invention discloses a three-core high-strength waterproof fire resistant cable. The cable comprises a cable core composed of a cable core body and two reinforcement cores. The cable core body is composed of a conductor, an insulating layer, an inner protective sleeve, a shielding layer and an outer protective sleeve from inside to outside in sequence. The two reinforcement cores are identical in structure, and each reinforce core is composed of a steel wire rope, a protective layer and an armored layer from inside to outside in sequence. The outer protective sleeve on the outmost layer of the cable core body is respectively connected with the armored layers on the outmost layers of the two reinforcement layers through plastic connecting parts. The cable is simple in structure, convenient and rapid to manufacture, low in production cost and high in abrasion resistance, through the two steel wire ropes on the outer side of the outer protective sleeve, the strength of the whole cable is enhanced, and the service life of the cable is prolonged. The outer protective sleeve is additionally arranged outside the cable core, so that the structure of the cable core is well protected and not prone to be damaged, and the service life of the cable is further prolonged. The cable further has better waterproof fire resistant performance.
Description
Technical field
The invention belongs to power cable field, be specifically related to a kind of three core high-strength waterproof fire-resisting cables.
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.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide that a kind of flexibility is better, water-and fire-proof is good, can be arbitrarily crooked and draw, three core high-strength waterproof fire-resisting cables of easily broken core not.
A kind of three core high-strength waterproof fire-resisting cables of the present invention, comprise that described cable core consists of conductor, insulating barrier, inner sheath, screen and oversheath from inside to outside successively by a cable core and two cable cores that strengthening core forms; Two described strengthening core structures are identical, consist of successively from inside to outside steel wire rope, protective layer and armour; The outermost oversheath of described cable core is connected with two outermost armours of strengthening core respectively by plastic fastening.
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, two described reinforced relative positions that are positioned at cable core, up and down relatively or left and right relative.
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.
Beneficial effect of the present invention is:
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; In addition, use 2 strengthening cores, more can strengthen the intensity of cable, make cable core not easily broken, more firm.

accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of three core high-strength waterproof fire-resisting cables of the present invention, comprise that described cable core consists of conductor 1, insulating barrier 2, inner sheath 3, screen 4 and oversheath 5 from inside to outside successively by a cable core and two cable cores that strengthening core forms; Two described strengthening core structures are identical, consist of successively from inside to outside steel wire rope 7, protective layer 8 and armour 9; The outermost oversheath 5 of described cable core is connected with two outermost armours 9 of strengthening core respectively by plastic fastening 6.The gap of described cable core is provided with packed layer 10, at the outer total oversheath 11 of one deck that extrudes again of whole cable core.
Two described reinforced relative positions that are positioned at cable core, up and down relatively or left and right relative; 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 invention provides a kind of three core high-strength waterproof fire-resisting cables; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
