Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a resistance to pressure layer structure has the connecting piece cooperation resistance to compression bolster of laying at the interval to form, and a plurality of connecting pieces are owing to do not belong to a whole, obtain the reinforcing in the aspect of the compressive resistance, simultaneously, utilize the space to add the fixed chamber of holding peppermint liquid, also possess more stable cable structure when also having guaranteed effectual protection against rodents.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1 sinle silk, 2 outer insulating sheath layers, 3 fire-retardant layers, 4 connecting pieces, 41 connecting portion, 42 outer fringe portion, 43 bulge, 5 resistance to compression bolster, 6 metal armor layers, 7 fixed chamber.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, a withstand voltage cable, including sinle silk 1, the sinle silk outside is provided with the internal insulation restrictive coating, and the sinle silk is provided with the multiunit, and the multiunit sinle silk outside is provided with external insulation restrictive coating 2, and it has fire-retardant layer 3 to fill between external insulation restrictive coating and the sinle silk, and the external insulation restrictive coating outside is provided with the withstand voltage layer structure, and the withstand voltage layer structure includes a plurality of connecting pieces 4 that lay at the even interval of external insulation restrictive coating outside circumference, the connecting piece cross-section is type T type, includes connecting portion 41 of being connected with the external insulation restrictive coating and the curved outer marginal part 42 that is of connecting portion integrated into one piece, and is gapped between outer marginal part and the external insulation restrictive coating, is provided with resistance to compression bolster 5 in the clearance, the outer marginal part outside still is provided with metal armor 6. The resistance to compression is realized by the cooperation of resistance to compression bolster and connecting piece, and the setting in connecting piece clearance also guarantees that the resistance to compression of connecting piece is stable.
Further, a convex portion 43 is provided at the middle portion of the outer edge portion to protrude outward. A plurality of fixed cavities 7 filled with peppermint liquid are fixed on the inner side wall of the metal armor layer, and the fixed cavities are arranged in gaps among the outer edge portion, the protruding portion and the inner side wall of the metal armor layer.
