Abstract

The invention belongs to the technical field of cables, and particularly relates to an anti-corrosion submarine cable which comprises a guide core. A conductor shielding layer is fixedly connected tothe surface of the guide core, and an insulating layer is fixedly connected to the surface of the conductor shielding layer. Through cooperative use of the fixing frame, the spring, the buffer plate and the fixing rod, a certain buffer effect can be achieved between the outer sheath and the strength layer, meanwhile, the outer sheath and the strength layer have good lightness and toughness, damageof seawater impact force to the cable can be effectively reduced, and therefore the compression resistance effect of the cable is improved, the service life is long and thepracticability is higher; the lead alloy layer, the carbon fiber layer and the semiconductor waterproof belt are used so that the cable can have extremely high corrosion resistance, the problem that the submarine cable is corroded is effectively avoided, the overall structure of the cable is protected, the use performance is more ideal, and meanwhile the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a corrosion-resistant submarine cable. Background technique [0002] Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, which are expensive, but have a high degree of confidentiality. However, the application occasions and laying methods are different. Since the submarine cable project is recognized as a complex and difficult large-scale project by countries all over the world, complex technologies are used from environmental detection, marine physical survey, and cable design, manufacture and installation. Therefore, submarine cable There are not many manufacturers in the world, mainly including Norway, Denmark, Japan, Canada, the United States, Britain, France, Italy and other countries. In addition to manufacturing, these countries also provide laying technology....
