Marine moisture-proof and corrosion-proof power cable

Abstract

The invention relates to a marine moisture-proof and corrosion-proof power cable. The power cable comprises a plurality of coaxial conductors. The conductors are distributed at the periphery and the center of a cable core. An insulating layer and a shielding layer are arranged outside the conductors to form an insulated conductor core. A composite waterproof warping tape is extruded outside the insulated conductor core to form the cable core. A metal corrosion-proof layer is arranged outside the cable core. A water-blocking layer is arranged outside the metal corrosion-proof layer. A sheath layer is arranged outside the water-blocking layer. The marine moisture-proof and corrosion-proof power cable is simple in structure, good in environment adaptability, water-blocking, moisture-proof, resistant to seawater corrosion, convenient to machine, and long in service life.

Description

technical field [0001] The invention relates to a power cable, in particular to a moisture-proof and corrosion-resistant power cable for ships. Background technique [0002] With the development of modern science and technology and the improvement of people's living standards, as well as the increasingly complex and high flexibility requirements of ship structures, people continue to pay more attention to the safety and environmental protection of ship cables. As the traditional insulation and sheath materials of flame-retardant cables, most of them are flame retardants mixed with halogen-containing polymers and halogen-containing flame retardants. Although these halogen-containing materials have excellent flame When the material is thermally decomposed and burned, a large amount of thick black smoke and toxic, corrosive, and irritating gases will be released, which seriously hinders firefighters from fighting fires and evacuating personnel, and will corrode equipment, delay...

As the traditional insulation and sheath materials of flame-retardant cables, most of them are flame retardants mixed with halogen-containing polymers and halogen-containing flame retardants. Although these halogen-containing materials have excellent flame When the material is thermally decomposed and burned, a large amount of thick black smoke and toxic, corrosive, and irritating gases will be released, which seriously hinders firefighters from fighting fires and evacuating personnel, and will corrode equipment, delay rescue time, and give Great losses to people's lives and property
