Cable for ocean platform and production process thereof

Abstract

The invention discloses a cable for an ocean platform. The structure of the cable is as follows: the innermost layer is a conductor, the conductor is formed by twisting a plurality of copper single wires, a polytetrafluoroethylene layer is arranged outside the conductor, a polypropylene film layer is arranged outside the polytetrafluoroethylene layer; the polypropylene film layer is externally provided with a water-blocking yarn layer, the water-blocking yarn layer is externally provided with a water-soluble film layer, the water-soluble film layer is externally provided with a dyeing layer, the dyeing layer is externally provided with a high-density polyethylene film layer, the high-density polyethylene film layer is externally provided with a ceramic fiber layer, and the ceramic fiber layer is externally provided with a polyurethane outer sheath layer. Through structural design and material combination, the cable is tensile and corrosion-resistant, and has the characteristic that a damaged part is easy to check and find.

Description

technical field [0001] The invention belongs to the technical field of cable preparation, and in particular relates to a cable suitable for ocean platforms. Background technique [0002] An offshore platform is a structure that provides production and living facilities for activities such as drilling, oil extraction, consolidation, observation, navigation, and construction at sea. As the country goes to the deep sea, a large number of offshore platforms emerge. As an important supporting equipment for offshore platforms, cables provide guarantee for the stable operation of offshore platforms. The humidity of the environment where the offshore platform is located is extremely high, and the seawater is also highly corrosive, which requires the tensile and corrosion resistance of the cable to be ensured. [0003] The water-blocking function of the water-blocking yarn is that when the main body of the water-blocking yarn meets water, it can expand rapidly to form a large jelly,...

AI Technical Summary

Problems solved by technology

[0004] There are many steel structures on offshore platforms. Under the corrosion of seawater, the steel structures are easy to form sharp edges and corners. Due to the blowing of waves and sea winds, the platforms will shake, so that the cables will rub against the steel structures of the platforms. After a long time, the cables will produce Damage, so that water vapor invades the cable, the cables are bundled together, and most of the damage points are on the side of the steel structure, which is easy to be ignored during the inspection
