Abstract

The utility model discloses a novel reel cable, and the cable is characterized in that the cable comprises conductors; each conductor is wrapped by a soft polyvinyl chloride insulating layer, thereby forming insulating cable cores; the center of a plurality of insulating cable cores is additionally provided with a hemp rope body, wherein the external diameter of the hemp rope body is slightly greater than that of each insulating cable core; the hemp rope body is wrapped by a soft polyvinyl chloride insulating layer, thereby forming a hemp rope cable core; the insulating cable cores and the hemp rope cable core are intertwisted tightly, thereby forming a stranded conductor; and the exterior of the stranded conductor is provided with a polyurethane elastomer in an extruded manner, thereby forming the novel reel cable. Because the hemp rope cable core serves as the central core of the stranded conductor, the hemp rope cable core plays a role in supporting when the insulating cable cores bends, thereby improving the buckling resistance and torsion resistance of the insulating cable cores. The polyurethane elastomer outside the stranded conductor is better in tension resistance, stretching resistance, toughness, and ageing resistance, and is also good in wear resistance, weather resistance, oil resistance, and ultraviolet resistance, thereby enabling the service life of the cable provided by the utility model to be greatly prolonged.

Description

A kind of novel winding drum cable

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of novel winding drum cable.

Background technology

At present, existing drum cable normally directly extrudes one deck insulator outward in insulated wire cores, and its useful life is very short, and especially, under extreme climate, its counter-bending ability and twisting resistance are just poorer.

Summary of the invention

In order to overcome above-mentioned defect, the utility model proposes a kind of novel winding drum cable.

The technical scheme that the utility model adopts is: a kind of novel winding drum cable, it is characterized in that: it comprises conductor, at the soft polyvinyl chloride insulation layer of conductor outer wrapping one deck, form insulated wire cores, in the middle of some insulated wire cores, add a rope made of hemp line body bigger compared with insulated wire cores external diameter, the external wrapped soft polyvinyl chloride insulation layer of rope made of hemp line, form rope made of hemp core, insulated wire cores and rope made of hemp core are closely stranded, form stranded conductor, the outer extrusion molding one deck polyurethane elastomer of stranded conductor, forms a kind of novel winding drum cable.

Because rope made of hemp core has been done the intermediate core of stranded conductor, when insulated wire cores is during in bending, there is rope made of hemp core to support, flexing resistance and the resistance to torsion of insulated wire cores have been increased, because the polyurethane elastomer outside stranded conductor has good tension stress, stretching resistance and high-strength tenacity and resistance to ag(e)ing, possess wear-resisting, weather-proof, oil resistant and anti-ultraviolet property simultaneously, therefore greatly improved useful life of the present utility model.

Embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described again.

As shown in Figure 2, a kind of novel winding drum cable, it comprises rope made of hemp line body 1, at the outer wrapped soft polyvinyl chloride insulation layer 2 of rope made of hemp line body 1, form rope made of hemp core 6, the outer wrapped soft polyvinyl chloride insulation layer 2 of conductor 3, forms insulated wire cores 5, the stranded composition stranded conductor 7 of rope made of hemp core 6 and insulated wire cores 5, the outer extrusion molding polyurethane elastomer 4 of stranded conductor 7.

Because rope made of hemp core has been done the intermediate core of stranded conductor, when insulated wire cores is during in bending, there is rope made of hemp core to support, flexing resistance and the resistance to torsion of insulated wire cores have been increased, because the polyurethane elastomer outside stranded conductor has high-tension, high-tensile strength, high-strength tenacity and resistance to ag(e)ing, possess wear-resisting, weather-proof, oil resistant and anti-ultraviolet property simultaneously, therefore greatly improved the useful life in the adverse circumstances such as high temperature, greasy dirt of the present utility model.
