4, the excellent conductive performance of restrictive coating material can guarantee that the earthing potential of all signal transmission apparatus of high ferro all fronts all keeps balance at any time; Restrictive coating adopts elastomeric material, has cushioned the Through ground wire surrounding medium to extruding and friction that Through ground wire produces, further improves this ground wire cable moral anti-seismic performance.
Considered the environmental protection factor during product development of the present invention,, not produce environmental pollution around can be along the line railway so this product material therefor is environment-friendly materials.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a sectional view of the present invention, illustrates structure of the present invention.
Among the figure: 1, earth lead, 2, the conductor core wire of alarming line, 3, the alarming line insulating barrier, 4, the packed layer of conductive elastomer material, 5, the restrictive coating of conductive elastomer material.
Embodiment
As shown in Figure 1; The present invention includes the conduction cable core; At the outer extrusion molding wrap jacket layer 5 that is with of conduction cable core, filling has inserts 4 between conduction cable core and said restrictive coating 5, and said restrictive coating 5 and inserts 4 are respectively the conductive elastomer through the polyolefin material of cross-linking radiation; Said conduction cable core is by warning wire 2 and its peripheral earth lead 1 of distributing is stranded constitutes, and the peripheral extrusion molding of the conductor core wire of said warning wire is enclosed with the insulating barrier 3 of polyolefin material elastic material.Further:
As shown in Figure 1; Said conduction cable core constitutes by 6 earth leads of 1 warning wire and its periphery that distributes are stranded; The conductor core wire of said warning wire 2 is made up of by conventional boundling is stranded conductive monofilament; Said earth lead 1 is made up of by left-hand is stranded conductive filament, and the embodiment of said earth lead 1 divides two kinds of situation:
Embodiment 1:
See Fig. 1; Each layer of earth lead 1 is made up of by regular structure arranged mode and by left-hand is stranded zinc-plated copper monofilament; The stranded pitch diameter ratio of said earth lead 1 each layer is increased progressively to internal layer by skin successively; Optimal cases is that said earth lead 1 outermost stranded pitch diameter ratio is 9, and the stranded pitch diameter ratio of all the other each layers of earth lead increases progressively 2 by skin to internal layer successively.Above-mentionedly be meant by regular structure arranged mode: the tin-coated copper monofilament quantity of every adjacent two layers differs 6, and is as shown in table 1.
Table 1 earth lead lay configuration and parameter
Embodiment 2:
See Fig. 1; The outermost of earth lead 1 is two-layer to be pressed regular structure arranged mode (identical with arrangement shown in the table 1) and is pressed the stranded formation of left-hand by zinc-plated copper monofilament 6; All the other each layers of earth lead 1 are pressed regular structure arranged mode (identical with arrangement shown in the table 1) and are pressed the stranded formation of left-hand by copper strand wire; The stranded pitch diameter ratio of said each layer of conductor cable core is increased progressively to internal layer by skin successively; Optimal cases is that said earth lead 1 outermost stranded pitch diameter ratio is 9, and the stranded pitch diameter ratio of all the other each layers of earth lead also is to increase progressively 2 successively by skin to internal layer.Above-mentionedly be meant by regular structure arranged mode
:That is: the two-layer tin-coated copper monofilament quantity of outermost differs 6, differs 6 by the quantity of from outside to inside order second layer tin-coated copper monofilament and the quantity of the 3rd layer of strand, differs 6 by from outside to inside order since the strand quantity of the 3rd layer of every adjacent two layers.In the present embodiment, table 1 is seen in the silk footpath of said zinc-plated copper monofilament, and the line footpath of said copper strand wire is chosen by conventional design or computational methods.
When earth lead 1 was stranded, the apolegamy of mould was very crucial, with the performance of presentation quality that is directly connected to conductor and cable.Aperture like selected mould is bigger than normal, can cause twisted wire to jump silk, and pitch is inhomogeneous, and conductor is rounding not, and the conductor diameter fluctuation is bigger; And the mould aperture is less than normal, can cause twisted wire to block up, and breaks, and it is difficult to wear silk, even conductor occurs and be the ring shape, and the tin pull-up falls, and D.C. resistance is defective.Through repeated calculation and trial-production, select the mould aperture to be of a size of 1.05 ~ 1.10 times of Theoretical Calculation conductor assembly outer diameter, stranded cable core surface-brightening, the pitch that goes out is even, and conductor assembly outer diameter rounding, does not evenly have the silk of jumping, burr, fracture of wire, drawing-down phenomenon.
