Embodiment Construction

[0013] like figure 1 , an ultra-flexible cable according to the present invention, comprising a cable conductor core 1, placing electrical steel wire, electrical steel wire rope, aramid wire or aramid rope as a reinforcing core 2 in the middle of the cable conductor core 1, The insulating layer 3 is extruded outside the core. The conductive core is braided with copper strands around the reinforcing core using a braiding machine. The diameter of steel wire for electrician is 0.20~1.0mm, the diameter of steel wire rope for electrician is 1.0~5.0mm, and the tensile strength is between 850~1550Mpa. The diameter of the aramid yarn is 0.20-1.0mm, and the diameter of the aramid rope is 1.0-5.0mm.

[0014] In the present invention, a high-strength thin steel wire (rope) for electrician is placed in the middle of the cable conductor core, and aramid fiber (rope) is used as a reinforcing core, and copper strands are used to weave around the reinforcing core by a braiding machine to fo...

Abstract

The invention discloses a super-flexible cable which has a rational structure and better tensile performance. The super-flexible cable comprises a cable conducting core, wherein an electrician steel wire, an electrician steel wire rope, an aramid yarn or an aramid rope are placed in the middle of the cable conducting core to serve as a reinforcing core. The conducting core is formed by weaving copper strand wires around the reinforcing core through a weaving machine. By optimizing materials used by the manufactured cable and rationally designing the cable structure, the cable has super flexibility and superior bending, winding, torsion and tension performances, so that requirements of some special occasions are met.

Description

[0001] technical field [0002] The invention belongs to the field of power cables, in particular to an ultra-flexible cable used on mobile equipment (such as port machinery, mining machinery, metallurgical tank trucks, wind power equipment, robot arms, etc.), the cable requires excellent bending, torsion, Torsional and tensile properties, so as to meet the needs of some special occasions. Background technique [0003] Almost all ports and wharves use hoisting machinery for transportation operations, mining under the mine has used more efficient mining equipment, and blast furnaces in the metallurgical industry are limited by environmental conditions, and molten metal can only be transported by rail tank cars..., The mechanical equipment in these occasions must use a special cable, one end of which is connected to the fixed end, and the other end is connected to the control box, cable reel or power generation equipment of these mechanical equipment. It moves frequently and ...
