Abstract
The invention discloses a composite power cable for ocean engineering. A cable core is formed by intertwisting three insulated wire cores, flame-retardant filling ropes and a control cable unit, each insulated wire core is formed by extruding a tinned soft copper conductor, a polyester film belting layer, and a crosslinked polyethylene insulating layer, the control cable unit is formed by extruding polyester tape belting and an armor layer after intertwisting three control wire cores and the flame-retardant filling ropes, the control wire core is formed by extruding a tinned soft copper conductor, a polyester film belting layer, and a crosslinked polyethylene insulating layer, and the cable core is provided with the polyester tape belting, an inner sheath layer, the armor layer and an outer sheath layer from inside to outside. The composite power cable for ocean engineering in the invention solves the problems of equipment power utilization, transmission control, and measurement signals, keeps characteristics of a common control optical cable and can also satisfy relevant standards of a low-voltage power transmission cable.
Description
Technical field
Invention relates to a kind of power cable, and particularly ocean engineering composite power cable, belongs to technical field of electric wires and cables.
Background technology
Since the sixties in 20th century, the mankind constantly increase the demand of mineral resources, the energy, start to ask for wealth to ocean on a large scale.Along with scientific and technical progress, the understanding of marine resources and environment thereof has been had to further raising, ocean engineering technology has also had very great development, and ocean development enters into new developing stage; Large-scale development submarine oil, natural gas and other solid mineral reserve, start to set up tide power plant and seawater desalting plant, fish for marine organisms to aquaculture future development from simple, utilize ocean space to build seadrome, seabed tunnel, marine factory, military base, seabed etc., formed some emerging ocean development industries.Along with the construction of various ocean engineerings, also more and more higher to the requirement of power cable for ocean engineering.
Summary of the invention
The object of the present invention is to provide a kind of ocean engineering composite power cable, make it solve equipment electricity consumption, transfer control, measuring-signal problem simultaneously, also retain the characteristic of general control optical cable and can also meet the relevant criterion of low voltage power transmission cable.
The solution of the present invention is as follows: a kind of ocean engineering composite power cable, its cable core is by three insulated wire cores, fire-retardant gasket for packing, the stranded composition in control cables unit, described insulated wire cores is by zinc-plated soft copper conductor, polyester film belting layer, crosslinked polyetylene insulated layer extrudes and forms, described control cables unit controls cores by three and fire-retardant gasket for packing extrudes polyester belt band after stranded, armour composition, described control core is by zinc-plated soft copper conductor, polyester film belting layer, crosslinked polyetylene insulated layer extrudes and forms, on described cable core, be respectively arranged with from inside to outside polyester belt band, inner restrictive coating, armour, external sheath layer.
Described inner restrictive coating and external sheath layer all adopt low smoke, zero halogen polyolefin inner restrictive coating material to make.
Described armour is for adopting metal wire knitted to form.
Beneficial effect of the present invention:
1, the present invention has increased control core in the construction of cable, integrate control, transmission of electricity copper cash, solve equipment electricity consumption, transfer control, measuring-signal problem, it has retained the characteristic of general control optical cable and can also meet the relevant criterion of low voltage power transmission cable simultaneously.
2, control cables of the present invention unit is provided with metal base transistor screen, has good shielding properties and interference free performance, has improved greatly the shielding properties of cable, has good anti-external electromagnetic field and disturbs and do not produce external interference.
3, in the present invention design, incorporate halogen-free flameproof, etc. characteristic thinking, used the material of environmental protection, based on the consideration of safety, use fire-retardant, Halogen material.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1 conductor, 2 belting layers, 3 insulating barriers, 4 gasket for packings, 5 fire-retardant belting layers, 6 inner restrictive coatings, 7 armours, 8 oversheaths.
embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of ocean engineering composite power cable, comprise from inside to outside the control cables conductor of three stranded power cable conductors of zinc-plated soft copper and three zinc-plated twisted copper conductors, not loose in order to ensure stranded conductor, closely, conductor 1 outside wrapped one deck polyester belt belting layer 2 plays to tighten and acts on and extrude crosslinked polyetylene insulated insulating barrier 3 and form and control cores, three control cores are first stranded together with fire-retardant gasket for packing 4, then extrude fire-retardant belting layer 5, fire-retardant belting layer 5 outsides arrange metal wire knitted armour 7, then three insulated wire cores, fire-retardant gasket for packing 4 and control cables unit are stranded together, then wrapped fire-retardant belting layer 5.Extrude halogen-free and low-smoke flame-retardant polyolefin inner restrictive coating 6 in fire-retardant belting layer 5 outsides, in inner restrictive coating 6 outsides, metal wire knitted armour 7 is set, extrude halogen-free and low-smoke flame-retardant polyolefin external sheath layer 8 in armour 7 outsides.
In structure of the present invention, increase control core, integrated control, transmission of electricity copper cash, solved equipment electricity consumption, transfer control, measuring-signal problem simultaneously.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
