Anti-corrosion submarine cable with low armoring loss for communication monitoring

Abstract

The invention relates to an anti-corrosion submarine cable with low armoring loss for communication monitoring, comprising a wire core (1), a shielding layer (2), an insulating layer (3), an insulator shielding layer, an inner protective layer (4), an armoring inner bedding layer (5), an armoring layer (7) and an armoring outer protective layer (8) which are sequentially arranged from inside to outside, wherein the armoring layer (7) consists of a plurality of non magnetic anti-corrosion metal wires (71), and an optical cable layer (6) is arranged between the armoring layer (7) and the armoring inner bedding layer (5). The anti-corrosion submarine cable has the advantages that serious eddy and magnetic hysteresis loss caused by a zinc-coated wire armoring structure can be eliminated, the allowed carry current of the cable is higher than that of the zinc-coated wire armoring cable by nearly 30 percent, the tensile strength of a submarine crosslinking power cable is ensured, and the armoring layer is formed by the non magnetic anti-corrosion metal wires, thereby having good anti-corrosion effect; besides, as a polyethylene protective layer is not needed to be coated outside the non magnetic anti-corrosion metal wires, good heat radiating effect is achieved, thereby meeting the communication and monitoring demands of the anti-corrosion submarine cable with low armoring loss for communication monitoring, reducing the armoring loss, being beneficial to heat radiation and ensuring anti-corrosion performance of armoring.

Description

technical field [0001] The invention relates to a low armor loss anti-corrosion submarine cable capable of communication monitoring, in particular to an anti-corrosion submarine cable capable of communication monitoring and low armor loss compounded with an optical cable. Background technique [0002] An existing Chinese utility model patent with the patent number CN200820034047.X titled "Submarine Optical Fiber Composite Power Cable" discloses a structure, which includes a conductor, an insulating layer, a water blocking layer, a metal sheath layer, and an inner sheath layer , inner cushion layer, outer sheath layer, armor layer, and outer layer, an insulating layer is arranged outside the conductor, a water-blocking layer is arranged outside the insulating layer, a metal sheath layer is arranged outside the water-blocking layer, and a metal sheath layer is arranged outside the water-blocking layer. There is an inner sheath layer outside the sheath layer; the outermost laye...
