Abstract
The utility model discloses a zero-buoyancy photoelectric composite cable. An optical fiber unit group is arranged at the center of the insulated core of the cable, insulated power lines and foamed polyethylene pipes are twisted on the outer layer of the optical fiber unit group to form the cable core, an aramid layer is braided on the outer layer of the cable core, and a first sheath layer and a second sheath layer are arranged outside the aramid layer successively. According to the cable of the utility model, the cable zero buoyancy requirement can be satisfied while satisfying other electrical performance and mechanical performance index requirements.
Description
Technical field:
The utility model relates to a kind of neutral buoyancy photoelectric compound cable.
Background technology:
Along with improving constantly of underwater communication technology, more and more harsher with the requirement of cable to pulling system under water, require not only that its external diameter is little, tensile strength is high, but also to have neutral buoyancy, the density that requires cable and the density variation of seawater be less than 3%, but aramid layers is arranged, the existence of fiber unit and copper core conductor owing in the cable, these materials are 1 times of the density of seawater to not waiting more than 8 times, and this has increased the manufacture difficulty of cable greatly.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of neutral buoyancy photoelectric compound cable, when satisfying other electrical property and mechanical performance index requirement, can also satisfy the requirement of zero in cable buoyancy.
The utility model technical solution problem adopts following technical scheme:
A kind of neutral buoyancy photoelectric compound cable, the center of cable insulation core is provided with the fiber unit group, consist of cable core at the outer strand insulation high power line of described fiber unit group and polyethylene foamed pipe, at described cable core outer braid aramid layers is arranged, described aramid layers is provided with the first restrictive coating and the second restrictive coating outward successively.
Described the first restrictive coating is successively by polyethylene layer, polyethylene foamed layer and polyethylene layer is compound consists of.
Described the second restrictive coating is successively by the polyethylene foamed layer and polyethylene layer is compound consists of.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, external diameter is little, economic benefits: the technological difficulties of neutral buoyancy cable maximum are the control of density, because equipment machining accuracy, the existence of the problems such as workman's operation technique, so that the realization of neutral buoyancy, very difficult, especially the close target of density in order to realize cable density and seawater in the sheath course of processing, the tradition manufacture process is often repeatedly processed, the outside diameter of cable of making like this is generally all very large, but also be difficult to realize producing in enormous quantities, and the three lager coextrusion foamed extruder is adopted in the making of the utility model cable, can control accurately simultaneously the thickness of the first restrictive coating internal layer and outer field polyethylene thin layer, while is according to the adjusting of temperature and speed, effectively controlled the foam degrees precision of intermediate layer polyethylene foamed layer, extrude and cable density is carried out integral body measure afterwards, calculate through accurate, carry out again extruding of the second restrictive coating, by fine setting outermost layer polyethylene thickness, realize the neutral buoyancy requirement of cable, so the manufacturing of this cable is saved 2-3 road manufacturing procedure than traditional manufacture process, external diameter reduces about 10%, economic benefits.
2, the technique realizability is strong: the Italian three lager coextrusion foamed extruder of specialty is workable, foam degrees can be as accurate as 0.06%, the external diameter tolerance can be controlled in the 0.1mm, and outermost layer polyethylene thin layer can carry out the thickness fine setting simultaneously, effectively guarantees the realizability of technique.
3, outward appearance is good, mechanical strength is good: conventional simple polyethylene foam can amplify the open defect of cable core, and the usually inadequate rounding of outward appearance, adopt scheme of the present utility model, successfully solved this problem, owing to all have the polyethylene thin layer at the polyethylene foamed layer, so that cable smooth in appearance rounding, greatly improved cable simultaneously and received resistance to compression deformability on the spool.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 fiber unit group, 2 power lines, 3 polyethylene foamed pipes, 4 aramid layers, 5 first restrictive coatings, 6 second restrictive coatings.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: referring to Fig. 1, the neutral buoyancy photoelectric compound cable of present embodiment, the center of cable insulation core is provided with fiber unit group 1, at the outer strand insulation high power line 2 of described fiber unit group and 3 one-tenth cable cores of polyethylene foamed pipe, at described cable core outer braid aramid layers 4 is arranged, described aramid layers is provided with the first restrictive coating 5 and the second restrictive coating 6 outward successively.
Described the first restrictive coating 5 is successively by polyethylene layer, polyethylene foamed layer and polyethylene layer is compound consists of.Described the second restrictive coating 6 is successively by the polyethylene foamed layer and polyethylene layer is compound consists of.
The cable of present embodiment makes by following technical process: outsourcing fiber unit group 1, respectively power line 2 and polyethylene foamed pipe 3 are stranded in fiber unit group 1 at fiber unit group 1 external application cabler and consist of cable core, in cable core external application 24 ingot braiding machines braiding aramid layers 4, the cable core of woven aramid fiber is wrapped up the first restrictive coating 5 through the three lager coextrusion foamed extruder, wrap up the second restrictive coating 6 at the three-layer co-extruded extruder of the first restrictive coating 5 external applications.
