Abstract

The invention discloses a traveling floating cable for offshore platforms, which comprises tin-plated copper conductors. Each tin-plated copper conductor is coated with a cross-linked polyethylene insulating layer. The cross-linked polyethylene insulating layers are coated with a carbon fiber braided shielding layer. A high-strength tensile filling layer is arranged between the cross-linked polyethylene insulating material and the carbon fiber braided shielding layer. The carbon fiber braided shielding layer is coated with a foamed polyethylene filling layer wrapping several control line cores. The foamed polyethylene filling layer is coated with a Kevlar fiber braided strengthening layer. A medium-density polyethylene inner sheath is arranged by extrusion outside the Kevlar fiber braidedstrengthening layer. A foamed polyethylene sheath is arranged by extrusion outside the medium-density polyethylene inner sheath. A medium-density polyethylene outer sheath is arranged by extrusion outside the foamed polyethylene sheath. Compared with traditional cables, the traveling floating cable for offshore platforms in the invention has the advantages of wind-resistant, waterproof, wear-resistant, tensile, light and environment-friendly.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to an accompanying floating cable for an ocean platform. Background technique [0002] With the rapid development of marine development, the requirements for the connection between equipment on offshore platforms and the control of accompanying equipment are getting higher and higher, and ordinary power cables and control cables can no longer meet the requirements. This is a big problem that needs to be solved. How to make the cable have a longer service life and a more stable control signal in the process of power transmission, so that the cable can play a greater role has become a problem faced by the power industry. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide an accompanying floating cable for offshore platforms to address the deficiencies of the prior art. [0004] Technical solution: In order to achieve the...
