Ocean high voltage-resistant and anti-corrosion cable convenient for replacement and maintenance

Abstract

The present invention discloses an ocean high voltage-resistant and anti-corrosion cable convenient for replacement and maintenance. The cable for ocean is fixed on a cable channel which is employed to have a secondary protection effect and facilitate replacement and maintenance, the laying construction is convenient, the cable is not completely in contact with the cable channel to have an effecton protection of the cable and improve the service life of the cable, the internal and external portions of the cable channel are coated with anti-corrosion coating, the anti-corrosion coating is coated with an asphalt coating layer at the outer side of the cable channel to have anti-corrosion and high voltage-resistant effects, the cable itself has high voltage-resistant and anti-corrosion performances, a titanium alloy sheath is employed in the cable, is better than a traditionally used titanium alloy sheath, is non-poisonous, high in intensity, good in anti-corrosion performance, not easy to break off and convenient for turning of the cable, and a resin insulation layer, a braided strap, a mothproof layer, a reinforcement layer, an anti-corrosion layer, a liner and an armour of the cable itself have a good protection effect on the cable core body so as to improve the service life of the cable on the ocean.

Description

Technical field: [0001] The invention relates to the field of marine cables, in particular to a marine high-voltage and corrosion-resistant cable that is easy to replace and maintain. Background technique: [0002] Submarine cables are cables wrapped in insulating material and laid on the seabed for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern undersea cables use fiber optics to transmit telephone and internet signals. The core of the submarine cable is made of high-purity optical fiber as thin as a hair, which guides light along the path of the optical fiber through internal reflection. [0003] The existing marine cables are very troublesome to lay, the project is large, and the efficiency is low. Generally, the cables are slotted in the seabed, and then the cables are buried in the slots, and then covered with cement covers. When the cables need to be repaired or damaged, they will b...

Problems solved by technology

[0003] The existing marine cables are very troublesome to lay, the project is large, and the efficiency is low. Generally, the cables are slotted in the seabed, and then the cables are buried in the slots, and then covered with cement covers. When the cables need to be repaired or damaged, they will be replaced. , it is necessary to pull the cable out of the groove, which is not only inefficient, but also inconvenient for laying next time. The existing marine cable is in direct contact with seawater. Service life, the existing cables use lead alloy as a protective material, which will produce toxic substances when the ocean corrodes, which poses hidden dangers to the life safety of marine organisms, and the existing cables have poor compression and corrosion resistance as a whole, and the replacement cost High, difficult to operate
