Description
Technical field
The utility model relates to a kind of underwater suspended optoelectronic composite cable.
Background technology
Along with the development of oceanology, surface platform equipment and more and more being used in seafari activity of underwater monitoring equipment. For these equipment provides electric power support and Signal transmissions service then to need to use optoelectronic composite cable. Common optoelectronic composite cable is from great, after laying, the drag force of surface platform equipment and underwater monitoring equipment is relatively big, will certainly affect the normal operation of equipment.
In order to reduce the own wt of optoelectronic composite cable, reduce and subsea equipment pulled impact, need to design the optoelectronic composite cable that a relative density is little, tensile strength is high, make the gravity of itself roughly equal with the buoyancy being subject to, such optoelectronic composite cable just can stop the optional position in water, reduce the stressing influence in operational process, reach the requirement suspended under water.
Practical novel content
The purpose of this utility model is to provide a kind of underwater suspended optoelectronic composite cable.
The technical solution adopted in the utility model is:
A kind of underwater suspended optoelectronic composite cable, comprise cable core and sheath, enhancement Layer, outer jacket, described cable core is by light unit, transmission of electricity copper cash unit and is positioned at light unit, the central reinforce member of transmission of electricity copper cash unit central authorities stranded forms, described smooth unit is 1 or 2, described transmission of electricity copper cash unit is 2, described sheath and outer jacket are wrapped on cable core successively, are provided with enhancement Layer between described sheath and outer jacket.
Described sheath, outer jacket are made up of Low Density Polyethylene.
Described enhancement Layer is Kafra fiber.
Advantage of the present utility model: rational in infrastructure, cable core adopt 1 light unit and 2 transmission of electricity copper cash unit or 2 light unit with 2 transmit electricity the stranded compositions of copper cash unit, the size of central reinforce member can be reduced, make cable core stranded compacter, reducing the deadweight of cable core, the design of interior outer jacket ensure that electrical property and the mechanical performance index of optoelectronic composite cable, and the tension that the design of enhancement Layer compensate for central reinforce member is not enough, reduce optoelectronic composite cable deadweight, ensure that electric property, optical property.
