Abstract

The utility model discloses a composite cable for ships and water platforms, which comprises three large conductors, two small conductors and insulating layers. Each of the three large and two small conductors is wrapped in one insulating layer; after wrapped and insulated, the two small conductors are intertwisted, lapped, braided and shielded to form a wire pair; and the wire pair and cores of three large insulated conductors are intertwisted to form a bundle. The cable core bundle is then wrapped in a belting layer, wherein flame retardant type glass fiber ropes as a filling layer are arranged between the belting layer and the insulating layers; an inner lining layer and an armored layer are wrapped around the belting layer, wherein the armored layer is braided by tin-coated copper wires, and the braiding density is no less than 90%; and a high-flame-retardation low-smoke halogen-free corrosion-resisting polyolefin sheath layer is wrapped around the armored layer. The composite cable of the utility model can meet low-smoke, halogen-free, flame-retardation and other performance indexes of ship and water platform cables, and at the same time solves moistureproof and anticorrosion problems.

Composite cable for ships and water platforms

technical field

The utility model relates to the cable industry, in particular to a composite cable for ships and water platforms. the

Background technique

Marine cables are special cables for power, lighting, control, communication and other systems of rivers, oceans and water construction platforms. As the main mode of logistics transportation in the world, shipping has always played a pivotal role. Since entering the 21st century, the center of the world's shipbuilding industry has gradually shifted to Southeast Asia, and my country has gradually become the world's largest shipbuilding and processing area, promoting the development of the world's shipbuilding industry. the

The traditional cables for ships and water platforms have always been difficult to solve the problems of oil resistance and corrosion resistance in the actual working environment. the

Utility model content

The utility model provides a composite cable for ships and water platforms, which can meet performance indicators such as low smoke, halogen-free, and flame retardancy of the ships and water platforms. At the same time, the cable also solves the problems of moisture resistance and corrosion resistance. the

The scheme of the utility model is as follows: a composite cable for ships and water platforms, including three large conductors, two small conductors, and an insulating layer. The outer sides of the three large conductors and the two small conductors are respectively wrapped with an insulating layer. After the small conductor is wrapped and insulated, it is twisted and shielded to form a wire pair group. The wire pair group is twisted with three large insulated wire cores to form a bundle. After the bundle is wrapped, the outside of the cable core is wrapped with a tape layer. Flame-retardant glass fiber rope is used as a filling layer between the insulating layer and the inner lining layer and armor layer are wrapped on the outside of the tape layer. The armor layer is braided with tinned copper wire, and the weaving density is Less than 90%, the outer side of the armor layer is wrapped with a high flame-retardant, low-smoke, halogen-free, corrosion-resistant polyolefin sheath layer. the

The cross-sectional area of the large conductor is 25-300mm ² , and the cross-sectional area of the small conductor is 1.0mm ² .

The insulating layer material is flame-retardant cross-linked polyolefin. the

The shielding of the wire pair group is braided with tinned copper wire. the

The inner lining layer is made of extruded polyolefin with high flame retardant, low smoke, halogen free and corrosion resistance. the

The armor layer of the utility model adopts a wire core composite structure, three large conductors are used for power transmission, two small conductors are used for signal transmission, and are protected by separate shielding to reduce the interference of external electromagnetic waves, tinned copper wire braided structure It is used for signal transmission and protected by separate shielding to reduce the interference of external electromagnetic waves. It is composed of tinned copper wire braiding, with high weaving density, good shielding performance, excellent resistance to external electromagnetic field interference and no external interference. The flame-retardant cross-linked polyolefin material is insulating and has excellent flame-retardant properties; the halogen gas released when the cable material is burned, the pH value and conductivity of the gas aqueous solution are low, and has low corrosion performance; the cable generates less smoke when burned, and has Wear resistance, tear resistance, oil resistance, ozone resistance, corrosion resistance, high flame retardancy and other properties. the
