Three-core cable is used for transferring electric power, use widely in power industry, the structure of existing three-core cable has three mutually insulated wires and is positioned at external insulation layer and the sheath of wire, its shortcoming is that wire easily ruptures when bending at external insulation layer electric wire, because wire is comparatively hard, existing three-core cable is not provided with buffer structure between wire.Owing to there is such problem, so be necessary to improve existing three-core cable.
Summary of the invention
The purpose of this utility model is deficiency in order to solve above-mentioned technology and a kind of three-core cable being provided with buffer structure between wire designed.
A kind of three-core cable designed by the utility model, comprise the wire that three are surrounded by inner insulating layer, also comprise external insulation layer and sheath, three wires are all positioned at external insulation layer, external insulation layer is located in the inner chamber of sheath, the equilateral triangle ring of the cross section of described external insulation layer to be a drift angle place be circular shape, described sheath lumen shape and external insulation layer match, described three wires are isosceles triangle distribution, the silicones packing that a cross section is concave lens shape is provided with between three wires, silicones packing makes three interior drift angles of three wires and external insulation layer hold out against.
As preferably:
External insulation layer built with fire-retardant powder, to improve the fire retardancy of three-core cable.
Described sheath outline is circular, and in the part that sheath wall thickness is larger, fluting is equipped with Noctilucent material;
The equilateral triangle ring of described sheath outline to be also drift angle place be circular shape, the inner chamber of sheath is setting on the upper side, and in the part that sheath bottom wall thickness is larger, fluting is equipped with Noctilucent material;
Described groove is fishtail;
Three-core cable designed by the utility model, structure is comparatively tangible, and three wires are isosceles triangle distribution, can bear larger pressure, intensity is higher, in pressurized situation, silicones packing is relatively soft, first produces deformation, wire is formed and effectively cushions, do not make wire form stronger very stiff and demanding situation, make wire not easy fracture, inner insulating layer not cracky like this, avoid bringing short circuit problem thus.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 three-core cable;
Fig. 2 is the structural representation of embodiment 2 three-core cable;
Fig. 3 is the structural representation of embodiment 3 three-core cable;
Fig. 4 is the structural representation of embodiment 4 three-core cable.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, three-core cable described by the present embodiment, comprise the wire 1 that three are surrounded by inner insulating layer 2, inner insulating layer 2 is low halogen polythene materials, wire 1 is aluminum steel or copper cash, also comprise the external insulation layer 3 of wear-resisting type polythene material formation and the sheath 4 of black rubber material formation, three wires 1 are all positioned at external insulation layer 3, external insulation layer 3 is located in the inner chamber of sheath 4, the equilateral triangle ring of the cross section of described external insulation layer 3 to be drift angle places be circular shape, described sheath 4 cavity shape and external insulation layer 3 match, the distribution in isosceles triangle of described three wires 1, the silicones packing 5 that a cross section is concave lens shape is provided with between three wires 1, silicones packing 5 makes three wires 1 hold out against with three interior drift angles of external insulation layer 3.Described sheath 4 outline is circular.
Three-core cable described by the present embodiment, its beneficial effect is: structure is comparatively tangible, and three wire 1 distributions in isosceles triangle, can bear larger pressure, intensity is higher, in pressurized situation, silicones packing 5 is relatively soft, first produces deformation, wire 1 is formed and effectively cushions, do not make wire 1 form stronger very stiff and demanding situation, make wire 1 not easy fracture, inner insulating layer 2 not cracky like this, avoid bringing short circuit problem thus.
Significantly, the layers of material mentioned in the present embodiment is not unique, and those skilled in the art should carry out screening to current material and replace.
Embodiment 2:
As shown in Figure 2, the three-core cable described by the present embodiment, as different from Example 1: described sheath 4 outline is circular, and in the part that sheath 4 wall thickness is larger, fluting is equipped with Noctilucent material 7.Described groove is fishtail, can fill Noctilucent material 7 better.Noctilucent material 7 can be styrene type fluorescer, coumarin type fluorescer, pyrazoline type fluorescer or benzo oxygen nitrogen type fluorescer.
Three-core cable described by the present embodiment, the line that three Noctilucent materials 7 of its outside are formed has glowing at night function, can be in sight at night, prevents electric shock accidents, and the line formation of three Noctilucent material 7 formation is that a kind of solid shows wide effect; Because sheath 4 outline is circular, its inner chamber is delthyrial cavity, and must form the part that described sheath 4 wall thickness is larger, difficulty that the part that this wall thickness is larger is slotted is less, and not too can affect the barrier propterty of sheath 4.
Embodiment 3:
As shown in Figure 3, the three-core cable described by the present embodiment, as different from Example 1: the equilateral triangle ring of described sheath 4 outline to be also drift angle place be circular shape, make three-core cable be comparatively pier triangular shape on the spot, structural strength is high.
Embodiment 4:
As shown in Figure 4, three-core cable described by the present embodiment, as different from Example 1: the equilateral triangle ring of described sheath 4 outline to be also drift angle place be circular shape, the inner chamber of sheath 4 is settings on the upper side, and in the part that sheath 4 bottom wall thickness is larger, fluting is equipped with Noctilucent material 7.Such three-core cable also has glowing at night function, can be in sight at night, prevents electric shock accidents.
Above-described embodiment is only to design of the present utility model explanation for example, and significantly, the protection range of this patent is not limited to above-described embodiment.
The various equivalent modifications or supplementary that those skilled in the art do above-described embodiment, all should fall into the protection range of this patent.
