Abstract

The invention discloses an insulating material for a cable insulating layer and an underwater composite cable, and mainly relates to the technical field of cables. The insulating material comprises an outer sheath, an armor layer, a waterproof layer and a flame-retardant layer, wherein the flame-retardant layer is internally provided with conductors and coated optical fibers which are distributed alternatively; loose tubes are arranged outside the coated optical fibers; the loose tubes are internally provided with frames; a shielding layer, an insulating layer, an insulating shielding layer, a taped covering and an inner sheath are arranged on the conductor; the insulating layer is made of an insulating material with following raw materials: a PVC (Polyvinyl Chloride) resin, white carbon black, a diphenyl ether resin, an MBS (Methyl Methacrylate) resin, a cresol-formaldehyde resin, a linseed alkyd resin, ethylene-propylene-diene-terpolymer rubber, fatty alcohol-polyoxyethylene ether, calcium stearate, calcined clay and the like. The insulating material has the beneficial effects that protection of the underwater composite cable is remarkably improved, the properties of the insulating material and the insulating layer are optimized and improved, and construction and use requirements of the underwater composite cable are met.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an insulating material for a cable insulating layer and an underwater composite cable. Background technique [0002] Submarine cable is a wire wrapped with insulating material and laid on the bottom of the water, mainly including underwater communication cables and underwater power cables. In recent years, the vigorous development of the economy has ushered in a period of rapid development in the development of oil and natural gas. The operation of underwater robots, the construction of platforms, and the connection of drilling platforms are all inseparable from cables. [0003] Based on its structural characteristics of "two cables in one", the composite cable has the advantages of saving cable laying channel resources, low cost, convenient operation and maintenance, etc., and is widely used in the laying of underwater cables. Due to the long-term impact, corrosion, accidental i...
