Problems solved by technology

[0002] At present, the insulating material of the marine power cables sold in the market is polyethylene, and the long-term working temperature is 85°C. In addition, in a high-temperature environment or when a fire occurs, the insulation of the cable will melt, causing phase-to-phase discharge of the conductors, which may cause a fire. Or an explosion occurs, causing power failure of fire fighting equipment and causing huge losses
In addition, there is a lack of shielded cables with high temperature resistance of about +200±2 degrees, wear resistance, anti-static interference, and high toughness in the wires used for connecting engines for ships and transportation engines, industry, and steel. The softness of the cable structure is very high. Traditional materials can no longer meet the needs of special environments, so it is necessary to develop a high-strength, corrosion-resistant, high-temperature-resistant marine engine control cable

Embodiment Construction

[0011] The shielded control flexible cable for marine engines consists of a conductor 1, a fire-resistant insulating layer 2, an insulator 3, an isolation layer 4, an inner lining layer 5, an armor layer 6, and an outer sheath 7. Cable conductor 1 adopts the fifth tinned conductor in GB3956, and the surface of conductor 1 is covered with a layer of fire-resistant insulating layer-mica tape. Isolation paper plays the role of anti-static interference, and has the characteristics of cold resistance, high temperature resistance, acid and alkali resistance and corrosive gas, waterproof and so on.

[0012] When the conductor cross section of the present invention is 1mm, the long-term allowable working temperature is -60~200±2°C, and when the temperature is 20°C, it is not greater than 18MΩ.km; when the temperature reaches 20°C, the insulation resistance is not less than 960MΩ.km.

[0013] The finished cables are subjected to AC voltage 50HZ voltage test.

[0014] Cable rated volta...

Abstract

The invention relates to a shield control soft cable for a ship engine, which is characterized in that a cable conductor adopts a fifth tinned conductor in GB3956, a refractory insulating layer, i.e. a mica tape is coated on the surface of the conductor, an insulator adopts an FEP insulating material which resists the high temperature of plus 250 DEG C, a layer of electricity isolated paper is longitudinally coated before cable shield weaving and performs the action of antistatic interference, and the shield control soft cable has the characteristics of cold resistance, high temperature resistance, acid and alkali and corrosive gas resistance, water prevention and the like and has the advantages of compact structure, softness, wearing resistance, flame retardance and the like.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a shielded control flexible cable used for marine engines. Background technique [0002] At present, the insulating material of the marine power cables sold in the market is polyethylene, and the long-term working temperature is 85°C. In addition, in a high-temperature environment or when a fire occurs, the insulation of the cable will melt, causing phase-to-phase discharge of the conductors, which may cause a fire. Or an explosion occurs, resulting in a power failure of the firefighting equipment, resulting in huge losses. In addition, there is a lack of shielded cables with high temperature resistance of about +200±2 degrees, wear resistance, anti-static interference, and high toughness in the wires used for connecting engines for ships and transportation engines, industry, and steel. The softness of the cable structure is very high. Traditional materials can no lon...
