Deep-sea cable with long direction waterproof characteristic for ship

Abstract

The invention relates to a ship deep sea cable with the vertical watertight characteristic, which is provided with three to six conductors, each of which is composed of copper wires stranded with high conductivity, and the surface of each copper wire is coated with sealant. Each of the conductor is extruded with insulating layers. The sealant filled between the insulating layer and the periphery to compose the cable. An isolated area layer is wound at the periphery of the cable core; an outer sheath is extruded at the periphery of the isolated area layer, wherein the insulating layer is made of ethylene-propylene rubber materials. The sealant is the nonflowing sealing gluewater. The outer sheath is made of the chlorinated polyethylene materials. The invention provides a ship deep sea cable used in the deep water, particularly used in the sea with vertical watertight characteristic, and the sea water can not impregnate into the inner of the cable.

Description

technical field [0001] The invention relates to a cable, in particular to a deep-water cable for ships with longitudinal watertight properties, and belongs to the technical field of electric wires and cables. Background technique [0002] In recent years, the scale of my country's shipbuilding industry has expanded rapidly, the output of ships has increased sharply, and the types and structures of ships have been continuously upgraded. It is imperative to strive to improve the localization of my country's ship supporting equipment and realize the leapfrog development of my country's ship supporting equipment. As the nerves and blood vessels of the ship, the marine cable is also an important supporting equipment for its localization. Cables are also directly related to the safety, reliability and advancement of ships. Ordinary cables cannot prevent seawater from infiltrating into other compartments and entering equipment through the interior of the cable when encountering s...

AI Technical Summary

Problems solved by technology

Ordinary cables cannot prevent seawater from penetrating into other cabins and equipment through the interior of the cable when encountering seawater, and cannot ensure that water enters the next door of the watertight compartment without passing through the cable.

At the same time, seawater entering the cable will also corrode the cable, causing the entire cable to be scrapped and even damage the precision equipment connected to the cable.
