Abstract

The invention discloses a corrosion proof cable used for an offshore oil platform. The corrosion proof cable comprise conductors, insulation cable cores and a sheath layer, wherein insulation layers respectively wrap the outer sides of the conductors to form cable cores; three cable cores are twisted and then are wrapped by aluminium wrapping belts to form the insulation cable cores; five insulation cable cores are combined and are wrapped by a copper wire braiding lining layer; an insulation cable core II of which a conductor is wrapped by an insulation layer is also arranged in the middle of the combination of the five insulation cable cores; a zinc-coated wire armor layer wraps the outer side of the lining layer; an inflaming retarding zero halogen anti-corrosion mud polyolefin sheath wraps the outer side of the armor layer. According to the cable, five insulation cable cores are arrayed, the superposition of electromagnetic waves of a variable frequency cable is reduced; the shielding layer is formed by copper wire braiding, the anti-interference characteristic is good, the armor layer adopts thick zinc-coated wire armoring, the mechanical injury can be prevented, and the corrosion and the embrittlement of the steel wire are effectively prevented by smearing pitch.

Description

technical field [0001] The invention relates to the cable industry, in particular to a corrosion-resistant cable for offshore oil platforms. [0002] Background technique [0003] The cable is usually a rope-like cable twisted by several or several groups of wires, and each group is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulated overlay. Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, aluminum alloy cables and so on. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0004] The corrosion resistance of traditional offshore oil platform cables to seawater in the actual working environment has always been a diffi...
