Abstract

The invention relates to a high voltage control and power integrated cable and a preparation method thereof, and belongs to the technical field of wires and cables. The high voltage control and powerintegrated cable comprises a control cable and a power cable, the power cable is located in the center of the cable, the control cable encircles the outer side of the power cable, and a shielding layer, a lining layer, an armor layer, an oxygen barrier and a sheathing layer are arranged on the outer side of the control cable. The preparation method of the cable comprises the steps of conductor stranding; insulating layer extruding; cabling, wherein the power cable is located in the middle, and the control cable is located outside; isolation layer wrapping, wherein polyester film is used for wrapping in a double-layer overlapping mode; shielding, wherein copper wire open lapping shielding and copper wire wrapping shielding are conducted; lining layer pressing wrapping; armor layer wrapping,wherein double galvanized steel strip wrapping is conducted; oxygen barrier wrapping, wherein overlapping wrapping is conducted by means of oxygen isolation belts; sheathing layer wrapping, wherein sheath extrusion production is conducted. The cable has the advantages of being good in roundness, small in wiring space, convenient for construction detection, simple in preparation technology, high in capacity of resisting external electromagnet interference and the like.
