Abstract

The invention relates to the technical field of manufacture of cables for marine engineering equipment, and specifically refers to a power cable for marine engineering equipment and a preparation technology thereof. The cable comprises a cabling wire core which is formed by stranding a plurality of insulated wire cores. Each insulated wire core comprises a cable conductor formed by stranding a plurality of tinned copper wires, the cable conductor is wrapped with a fireproof layer, and the fireproof layer is wrapped with an insulating layer. The outer layer of the cabling wire core is provided with an oil-resistant inner sheath layer, and a filling rope is arranged between the oil-resistant inner sheath layer and the insulated wire cores. The outer layer of the oil-resistant inner sheath layer is provided with a braided armoring layer, and an oil-resistant outer sheath layer is arranged outside the braided armoring layer in an extruding manner. The power cable for marine engineering equipment disclosed by the invention has the characteristics of compact structure, high mechanical strength, flame retardancy, ultraviolet resistance, fireproofing, high oil resistance, and no pollution after combustion. Because of the improvement of the preparation technology, the overall mass of the cable is reduced and optimized obviously, and the distortion resistance of the cable is improved greatly.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing for marine engineering equipment, in particular to a power cable for marine engineering equipment and a preparation process thereof. Background technique [0002] With the vigorous exploitation of marine resources in various countries in the world, the rapid development of marine engineering has led to the continuous expansion of the demand for cables for marine engineering, and also put forward very high technical requirements for them. Offshore engineering cables refer to special cables used in offshore engineering projects, such as power, control and instrument cables used in various drilling rig modules, oil production platforms and other projects. In addition to requiring high mechanical strength and fire resistance, they also require excellent oil resistance performance. [0003] In the prior art, marine engineering cables are generally used instead of marine cables, and their o...
