Abstract
The utility model discloses a kind of three core high-strength waterproof fire-resisting cables, comprise that described cable core is made up 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, are made up 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.This construction of cable is simple, it is convenient to manufacture, production cost is low, and anti-wear performance is high, by 2 steel wire ropes 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.
Description
Technical field
The utility model belongs to power cable field, is 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 structure such as the mineral insulations such as magnesium oxide and metallic copper sheath, due to the restriction of 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 excellence, 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 DEG C of 3h of A level that specify in Britain BS6387, 750 DEG C of 3h of B level, 950 DEG C of 3h of C level, the combustion requirements of 950 DEG C 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 bending 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 that a kind of flexibility is better, water-and fire-proof is good, can be arbitrarily bending 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 described in the utility model, comprise that described cable core is made up 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, are made up 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 is made up 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; In addition, use 2 strengthening cores, more can strengthen the intensity of cable, make cable core not easily broken, more firm.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of three core high-strength waterproof fire-resisting cables described in the utility model, comprise that described cable core is made up 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, are made up 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 is made up 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 three core high-strength waterproof fire-resisting cables; 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 improve and also should be considered as protection range of the present utility model.
