Abstract
The invention discloses a seismic-isolation five-core flat cable. The cable is of a flat structure, three phase line cores in parallel are arranged in the center of the cable, multiple soft springs in one semicycle and multiple hard springs in the other semicycle are arrayed outside the phase line cores in parallel, the soft springs and the hard springs are externally wrapped by an elastic inner sheath, and the elastic inner sheath is wrapped by a sheath in an extruded mode. The seismic-isolation five-core flat cable is safe, reliable, good in seismic-isolation effect and long in service life.
Description
Technical field
The present invention relates to electric wire field, especially a kind of shock insulation type five core flat cable.
Background technology
For earthquake prone areas, the cable being embedded in underground is given a shock for a long time, easily breaks down, and existing cable lacks corresponding isolation measure.
Five-core cable in prior art, usual structure is all that five to be extruded with the circular core of insulation stranded, or four segment conductor-cores and a circular core stranded.Five-core cable core comprises five identical cores such as grade of five cross-sectional area of conductor, " three large two little " core that three cross-sectional area of conductor are large, two cross-sectional area of conductor are little or " four large one little " core that four cross-sectional area of conductor are large, cross-sectional area of conductor is little, lack corresponding isolation measure, cause decline to a great extent the useful life of cable.
Summary of the invention
The present invention is the shortcoming overcoming prior art existence, and provide a kind of safe and reliable, isolating affection is good, the shock insulation type five core flat cable of long service life.
For solving above technical problem, a kind of shock insulation type five core flat cable of the present invention, this cable is squashed structure, cable center is provided with three phase cores arranged side by side, at the outer laid out in parallel half-turn some slinky springs of phase core and half-turn some hard springs, slinky spring and the outer wrapped elasticity inner sheath of hard spring, extrude sheath outside elasticity inner sheath.
Described phase core is by phase conductor and wrappedly form at the outer elasticity inner sheath of phase conductor.
Described hard spring is formed by supporting to play the heart and be extruded in support bullet heart elasticity protective case.
Described phase conductor forms by some monofilament are stranded.
Described slinky spring is with the equidistant gap arrangement of hard spring or be covered with in the side of phase core periphery, and both quantity is identical.
Beneficial effect of the present invention is: carry out shock insulation protection by slinky spring, hard spring and oven wire mesh blanket to phase core and control conductor, effectively can improve the useful life of cable in the area that earthquake is multiple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, a kind of shock insulation type five core flat cable of the present invention, this cable is squashed structure, cable center is provided with three phase cores 1 arranged side by side, at the outer laid out in parallel half-turn of phase core 1 some slinky springs 4 and half-turn some hard springs 7, slinky spring 4 wrapped elasticity inner sheath 3 outer with hard spring 7, extrudes sheath 5 outside elasticity inner sheath.Described phase core is by phase conductor 2 and wrappedly form at the outer elasticity inner sheath 3 of phase conductor 2; Described hard spring 7 plays the heart 8 by support and is extruded in the support bullet heart 8 elasticity protective case 9 and forms; Described phase conductor 2 forms by some monofilament 6 are stranded; Described slinky spring 4 is with the equidistant gap arrangement of hard spring 7 or be covered with in the side of phase core periphery, and both quantity is identical.
Above-mentioned is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improve and adjustment also should be considered as protection scope of the present invention.
