The utility model has the advantages of the cable crookedness is good, and life is high, and simple structure, lays the convenience at light in weight.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to the low induction cable of a kind of lightweight symmetric formula.
Background technology
Low induction cable is that when having transmission, voltage is little, the feature that output current is large, therefore, cable certainly will have a large amount of heat and produce in running, in order to ensure that the heat that cable produces when small voltage big current can not have an impact to cable, prior art is mainly adopted and is solved in two ways:
(1) the netted insulating barrier of rubber and plastic is extruded with on every root cable conductor surface, during use, cooling water directly enters in outer sheath tube, make all to be filled with moisture content between cable insulation core, therefore can implement cooling to cable, ensure that the temperature stabilization of cable in running.
(2) be provided with at the cable core center of cable the sebific duct that a cross section is spoke-like core frame, the surrounding of sebific duct is provided with insulated wire cores, in sebific duct, pass into water during use, when big current small voltage, cable can take away heat by the water in sebific duct, ensure that the normal use of cable.
Prior art mainly has following problem:
Owing to needing to pass into water when cable uses, therefore need the use of a set of special equipment guarantee cable, due to adding of other equipment, the stability in use of cable is reduced, easily because the use of the problems affect cables such as the maintenance of special water flowing equipment.
Its weight of cable passing into water increases, be not suitable for using in some environment, simultaneously such cable tool is owing to adding spoke-like core frame sebific duct, or online wicking surface is extruded with the netted insulating barrier of rubber and plastic and adds the outside diameter of cable, too increase the bending radius of cable simultaneously, be inconvenient to lay.
Utility model content
The utility model is in order to solve the problem of prior art, and providing one, to have cable bend degree good, high life, and structure is simple, lightweight, lay the low induction cable of lightweight symmetric formula easily.
The low induction cable of a kind of lightweight symmetric formula described in the utility model, the bosom of this cable is provided with high strength strengthening core, with high strength strengthening core for the center of circle is outer respectively around interior phase wire core layer, foreign minister's wire core layer at strengthening core, wrapped first belting layer between interior phase wire core layer and foreign minister's wire core layer, outer wrapped second belting layer of phase wire core layer, extrudes outer jacket at the outermost layer of cable outside; Described interior phase wire core layer is made up of the first-phase phase wire core of the identical spaced arrangement of structure and second-phase phase wire core; Described foreign minister's wire core layer is made up of the first-phase phase wire core of a pair axisymmetric signal cable and the identical spaced arrangement of structure, second-phase phase wire core.
Further improvement, described high strength strengthening core is made up of high strength aramid fiber rope and the rubber sheath be extruded in outside high strength aramid fiber rope.
Further improvement, described first-phase phase wire core is formed by conductor and the insulating barrier be extruded in outside conductor with second-phase phase wire core.
Further improvement, described signal cable is made up of a pair pair twist signal core and the metal screen layer be extruded in outside signal core.
Further improvement, described signal core is made up of signal conductor and the signal isolation be extruded in outside signal conductor.
Compared with prior art, the utility model beneficial effect is:
1, the total inside and outside two-phase of the phase line of cable transmission electric power, each phase phase line is made up of phase wire core, by place in circuit in parallel for every core during use; Phase line adopts mode arranged side by side compared with single core, and the advantage that under having same cross section, core resistance in parallel is little, therefore increases the transmission quantity of electric current.Every root core sectional area is identical simultaneously, and the magnitude of current of its conveying is identical, decreases the generation of heat.And ground floor and second layer phase wire core are when arranging in cable, the core of each phase line adopts holohedral symmetry mode, and on the one hand, average electromagnetic induction, also improve cable stability on the other hand, when there being core to occur damaged, cable can normally work.
2, the cross section due to each phase line is little, in order to ensure the useful life of cable, be provided with a strengthening core at cable bosom layer, the stress point of cable is at core, such guarantee cable stress point of cable in BENDING PROCESS hits at center, ensure that the safety of cable core.
3, in order to improve the bending property of cable, in cable core, ground floor phase line, second layer phase line are all surrounded with belting layer outward, and in BENDING PROCESS, cable is inner than being easier to Relative sliding, and be more prone to bending, bending property is better.
4, cable inside is provided with signal core, and in order to ensure that signal core is not subject to the impact of power wire core in transmitting procedure, signal core has woven layer of metal shielding outward.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The low induction cable of a kind of lightweight symmetric formula as shown in Figure 1, the bosom of this cable is provided with by high strength aramid fiber rope 1 and is extruded in the high strength strengthening core that the rubber sheath 2 outside high strength aramid fiber rope 1 forms, with high strength strengthening core for the center of circle is outer respectively around interior phase wire core layer and foreign minister's wire core layer at strengthening core, wrapped first belting layer 5 between interior phase wire core layer and foreign minister's wire core layer, outer wrapped second belting layer 9 of phase wire core layer outside again, finally extrudes outer jacket 10 at the outermost layer of cable; Described interior phase wire core layer is made up of three first-phase phase wire cores of the identical spaced arrangement of structure and three second-phase phase wire cores; Described first-phase phase wire core is formed by conductor 3 and the insulating barrier 4 be extruded in outside conductor 3 with second-phase phase wire core; Described foreign minister's wire core layer is made up of a pair axisymmetric signal cable and five first-phase phase wire cores of the identical spaced arrangement of structure, five second-phase phase wire cores; Described signal cable is made up of a pair pair twist signal core and the metal screen layer 8 be extruded in outside signal core; Described signal core is made up of signal conductor 6 and the signal isolation layer 7 be extruded in outside signal conductor 6.
The utility model embody rule approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
