Abstract

The invention provides a degradable deep-sea cable. The degradable deep-sea cable comprises an optical fiber transmission cable, a power transmission cable, a first coating layer and a second coating layer, wherein the optical fiber transmission cable is coated with the first coating layer; the power transmission cable is twisted together with the optical fiber transmission cable coated with the first coating layer; the power transmission cable and the optical fiber transmission cable which are twisted together are coated with the second coating layer. The degradable deep-sea cable has the beneficial effect that the buoyancy force of the cable is increased effectively, and the buoyancy force of the cable can be controlled by controlling the quantity of air bubbles in a cable sheath, so that the cable can dive to a preset depth in the sea; moreover, a shielding layer is designed by weaving fine copper wires, so that the shielding layer can be effectively prevented from damaging the cable when being fractured, and effective tensile strength can be provided for the cable.

Description

technical field [0001] The invention belongs to the technical field of submarine cable design, in particular to a degradable deep-sea cable. Background technique [0002] In the existing technology, ordinary submarine cables generally use optical fiber transmission. Due to the high transmission speed of optical fiber, it is widely used for submarine transmission, and the submarine cable sheaths are made of plastic materials such as PVC, and PVC materials are used as submarine cables. Although the sheath of the cable can effectively improve the seawater erosion resistance of the sheath, the buoyancy of the sheath itself is small and cannot effectively provide a certain buoyancy for the submarine cable. Therefore, ordinary submarine cables have certain limitations in providing buoyancy. Defects. Contents of the invention [0003] The object of the present invention is to provide a degradable deep-sea cable, which not only combines optical fiber cables and power transmi...
