Abstract

The invention discloses a sea cable comprising a sea cable comprising 4 cable wires; the surfaces of the 4 cable wires are provided with a glass fiber insulation layer; a ceramic polyolefin thermal-insulation layer is arranged between the cable wire and the glass fiber insulation layer; one side, far away from the ceramic polyolefin thermal-insulation layer, of the glass fiber insulation layer isprovided with a waterproof layer; the waterproof layer comprises a polyethylene glycol terephthalate layer. The waterproof layer, the polyethylene glycol terephthalate layer, a polyurethane layer, a PTFE layer, a corrosion resistance layer, a polyethylene layer, an epoxy resin layer, a polycarbamate layer and an aluminium alloy protection layer are matched in usage, thus solving the problems thatan existing sea cable is poor in a waterproof corrosion resistance effect on the seabed, so the cable is easy to be damaged; the sea cable is good in waterproof corrosion resistance effects, can prolong the sea cable service life, and can improve the practical value of the sea cable.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a marine cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Insulated covering layer, the cable has the characteristics of internal electrification and external insulation. [0003] When laying cables on the seabed, it is necessary to use marine cables, but the existing marine cables have poor waterproof and corrosion resistance on the seabed, which leads to the phenomenon that the cables are prone to damage, which makes the service life of marine cables shorter and reduces the practicality of marine cables. sex. Contents of the invention [0004] The object of the present invention is to provide a marine cable which has the advantages of good waterproof and corrosion resistance, an...
