Abstract

The invention discloses a medium and high-voltage cable for moving a petrochemical device and a manufacturing method thereof. A semiconducting conductor shielding belt, a semiconducting conductor shielding extruding and wrapping layer, an oil-resistant rubber insulating layer, a semiconducting insulating shielding extruding and wrapping layer and an insulating shielding braiding reinforcing layer are sequentially arranged outside a stranded copper conductor; three insulating shielding phase wire cores are provided with central tensile components; three grounding wires and a plurality of tensile filling cores are integrally stranded into a cable core; and an oil-resistant rubber inner lining layer, an aluminum foil polyester composite belt shielding layer, a tin-coated copper wire braided shielding layer, an oil-resistant rubber inner sheath, an armored braided layer and an oil-resistant rubber outer sheath are sequentially arranged at the periphery of the cable core. A multiple shielding effect is achieved by the cable, and the oil-resistant rubber insulating layer, the oil-resistant rubber inner sheath and the oil-resistant rubber outer sheath achieve a triplex protection effect, so that the oil resistance of the cable is better. The central tensile components are arranged in the center of the three insulating shielding phase wire cores, and the tensile filling cores are arranged at the peripheries of the three insulating shielding phase wire cores, so that the cable can bear high tensile force.

Description

technical field [0001] The invention relates to a cable, in particular to a medium and high voltage cable for petrochemical equipment movement; the invention also relates to a manufacturing method for a medium and high voltage cable for petrochemical equipment movement. Background technique [0002] Liquefied natural gas ships are known as the jewel in the crown of shipbuilding. Along with the development of petrochemical marginal oil and gas fields, they have promoted the construction and development of LNG-FPSO, a floating LNG production, storage and transportation device that integrates LNG production, storage and unloading, as a new project The particularity of the industry and its working environment full of flammable and explosive oily gas has extremely high requirements for supporting cables. The existing medium and high voltage cables cannot meet the comprehensive performance of stability, shielding, softness, oil resistance and corrosion resistance, and compactness. ...
