Multilayer slurry-resistant fireproof cable

Abstract

The invention discloses a multilayer slurry-resistant fireproof cable, and relates to the technical field of cables. The cable comprises a cable body, wherein the cable body comprises an outer coatingsleeve, a woven mesh and an inner coating sleeve which are sequentially connected from outside to inside; three cable cores are arranged in the inner coating sleeve, and a tensile rope is arranged inthe inner coating sleeve; glass fiber filling ropes are arranged in the inner wrapping sleeve in an array mode. Cavities are formed between the inner wall and the outer wall of the inner wrapping sleeve in an array mode. The cavities are filled with a flame retardant. The cable core is protected through a double-coating-sleeve structure so that the corrosion resistance of the cable is improved; the flame retardant is arranged in the cavity in the inner coating sleeve, strong endothermic reaction occurs under high-temperature adjustment, part of heat released by combustion is absorbed, the temperature of the cable is reduced, production of combustible gas is effectively inhibited and thus combustion spreading is prevented. Tthe cable core is further protected by the aid of the glass fiberfilling ropes, and the fireproof performance of the cable is effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a multi-layer mud-resistant fireproof cable. Background technique [0002] With the continuous consumption and depletion of onshore oil and gas resources, the ocean is gradually becoming the main field of oil and gas development in the world, and it is showing a trend of developing to the deep sea and polar regions. With the acceleration of the localization rate of oil platform production, the number of domestic oil platform cables used by some domestic enterprises in the offshore industry is increasing year by year, and the demand for domestic oil platform cables is increasing. [0003] Existing oil platforms have complex structures, dense personnel, many combustibles, and are relatively isolated. Once a fire breaks out, it is difficult for personnel to escape and rescue. For example, it will cause casualties and economic losses. The cables have been eroded by mud or oil sludge f...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-layer mud-resistant fireproof cable. The cable core is protected by a double-coating structure, so that the anti-corrosion performance of the cable can be improved, and a resistance is set in the cavity inside the inner coating. It solves the problems of poor flame retardancy, mud resistance and corrosion resistance of cables used in existing oil platforms
