The disadvantage is that when a fire breaks out, the performance of the cable to prevent the flame from spreading is not strong, and the flame is easy to spread to the insulating layer, causing great hidden dangers to the safety of ships and personnel.
[0003] For marine composite control cables, the flame retardant performance is very high. When the cable is on fire, the ordinary structure of the cable cannot effectively prevent the flame from spreading.
Moreover, the main reason for the fire of the cable is that the conductors have too much carrying capacity, and the heat emitted by each conductor is concentrated in the cable core. Once the temperature reaches the spontaneous ignition point of the filling material, the cable will definitely catch fire.

The invention discloses a marine composite control cable. The marine composite control cable comprises a center control cable, X external control cables and X thermal baffles. The X thermal baffles are used for separating the center control cable and the X external control cables. A center control conductor is located between every two adjacent thermal baffles. The external control cables are surrounded and covered by the thermal baffles in a half mode, and the opening of the thermal baffles faces the outer side of the center control cable. The external control cables are sequentially coated with inner inflaming-retarding wrapping belt lapped covering layers, tinned copper belt lapped covering layers, external inflaming-retarding wrapping belt lapped covering layers and polyolefin outer sheath layers. The external control cables abut against the inner inflaming-retarding wrapping belt lapped covering layers and extrude the thermal baffles on the center control cable. According to the marine composite control cable, the phenomenon that due to the fact that the heat emitted by the conductors is centralized on a cable core, spontaneous combustion is caused is avoided, and the service life of the control cable is prolonged.
Description
technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a composite control cable for ships. Background technique [0002] With the development of the shipbuilding industry, especially with the development of large-tonnage ship technology, the demand for cables for ships is also increasing. With the development of science and technology, the requirements for cables matching ships are getting higher and higher. The flame retardant cables usually used basically use flame retardant insulating materials, flame retardant tapes, flame retardant fillers, and flame retardant sheath materials. Its disadvantage is that when a fire breaks out, the performance of the cable to prevent the flame from spreading is not strong, and the flame is easy to spread to the insulating layer, causing great hidden danger to the safety of ships and personnel. [0003] For marine composite control cables, the flame retardant performance is ver...
