Embodiment 1

[0030] See figure 1 , a flexible torsion-resistant and tensile flexible cable for an electro-hydraulic vehicle, from the inside to the outside is a composite conductor 100, an inner insulation layer 200, a reinforcement layer 300 and an outer insulation layer 400; the composite conductor 100 includes 7 groups of conductor groups 110 and 6 bundles of copper foil tows 120; the 7 sets of conductor groups 110 are normally twisted in the manner of 1+6; the conductor groups 110 include 7 strands of conductor units, which are normally twisted in the manner of 1+6; The conductor unit adopts 40 copper wires arranged in a structure of 1+7+13+19; the conductor structure arranged in the above way is more compact and stable.

[0031] See figure 1 , the above-mentioned 6 bundles of copper foil tows 120 are respectively arranged in 6 gaps formed between the 6 groups of conductor groups 110 located in the outer layer and the 1 group of conductor groups 110 located in the center, so as to inc...

Abstract

The invention discloses a flexible torsion-resistant tensile flexible cable for an electric hydraulic vehicle. The flexible torsion-resistant tensile flexible cable sequentially comprises a compositeconductor, an inner insulating layer, a reinforcing layer and an outer insulating layer from inside to outside, wherein the composite conductor comprises seven conductor groups and six copper foil wire bundles; the seven conductor groups are twisted regularly according to a 1 + 6 mode. The six copper foil wire bundles are respectively arranged at six gaps formed between the six conductor groups positioned on the outer layer and the one conductor group positioned in the center. The conductor groups of the cable conductor adopt a 1 + 6 structure, so that the structure of the cable is more stable; and the six copper foil wire bundles are respectively arranged at six gaps formed between the six conductor groups positioned on the outer layer and the conductor group positioned in the center, sothat the tensile property of the cable is improved.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a flexible torsion-resistant and tensile-resistant flexible cable for an electrohydraulic vehicle. Background technique [0002] With the development of the times, electro-hydraulic vehicles in industrial production and cargo transportation have gradually replaced the previous mechanical hydraulic vehicles. The cables of electro-hydraulic vehicles will be exposed to mineral oil in the environment, and the cables are required to be oil-resistant, high-temperature resistant, soft, and wear-resistant. The current hydraulic vehicle cable is composed of three parts: conductor, insulation layer and reinforcement layer. During use, the tensile performance and torsion performance are poor, the service life is short, the structure is simple, and the stability is insufficient. Contents of the invention [0003] The purpose of the present invention is to provide a flexible torsion-resis...
