Abstract
The utility model relates to a boring screen cable for the petroleum platform provided with an insulation wire core therein and a casing there out, wherein the insulation wire core is provided with an internal core conductor and an extrusion insulation layer; and the outside of the insulation wire core is provided with a braided shield layer and an shield layer. The cable is characterized in that the internal core conductor is provided with a wound wrapping layer; the wound wrapping layer is provided with an extrusion insulation layer; the insulation layer is provided with a braided shield layer; and the braided shield layer is provided with a extrusion protection layer.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, particularly relates to a kind of used for oil platform probing shielding power cable.
Background technology
At present, existing used for oil platform probing power cable, in insulated wire cores is arranged, restrictive coating is arranged outward, insulated wire cores has interior core conductor and extrudes insulating barrier, outside the insulated wire cores for extruding restrictive coating.When this cable is used for the electrical power transmission system of heavy-duty motor on the oil platform derrick, compressor and various pump classes and ship power system, because cable size is bigger, there is the relatively poor relatively shortcoming of flexibility, and cable does not have screen, cable is to external radiation and be subjected to external disturbance serious, the ac magnetic field instability easily causes electric system and the control system problem of being subjected to.
Summary of the invention
The utility model provides a kind of used for oil platform probing shielding power cable for solving the problem that existing known technology exists.
The purpose of this utility model provides a kind of flexibility, resistance to wear is good, has anti-bending, oil resistant, the special-purpose probing shielding of oil platform fire-retardant, that avoid disturbing power cable.
Used for oil platform probing power cable mainly is suitable for the electrical power transmission system and the ship power system of heavy-duty motor, compressor and various pump classes on rated voltage 2kV and the following oil platform derrick.This cable has increased woven shield on original property basis, strengthened the protection and the processing safety of cable.
The utility model adopts following technical scheme:
Used for oil platform probing shielding power cable, in insulated wire cores is arranged, restrictive coating is arranged outward, insulated wire cores has interior core conductor and extrudes insulating barrier, and the insulated wire cores outside is a screen, and screen is outer for extruding restrictive coating, be characterized in: interior core conductor has lapping layer outward, lapping layer is extruded insulating barrier outward, and insulating barrier has woven shield outward, and woven shield is extruded restrictive coating outward.
The utility model can also be taked following technical measures:
Described used for oil platform probing shielding power cable, be characterized in: lapping layer is nonwoven layer or polyester rete.
Described used for oil platform probing shielding power cable, be characterized in: core conductor is stranded tinned copper wire in the insulated wire cores.
Advantage that the utlity model has and good effect:
This cable compared with prior art, as used for oil platform probing power private cable, has following characteristics owing to adopted the technical program:
1, this cable is specially adapted to the electrical power transmission system and the ship power system of heavy-duty motor, compressor and various pump classes on rated voltage 2kV and the following oil platform derrick.
2, to have solved common power cable diameter bigger for this cable, and the shortcoming of flexibility relative mistake has good softness.
3, this cable has good anti-wear performance, can adapt to the special mounting environment.
4, this cable has characteristics such as oil resistant, fire-retardant, anti-daylight, low temperature resistant, humidity, low-smoke low-halogen.
5, this cable has increased woven shield on original property basis, has increased the fail safe that product uses in electromagnetic compatible environment.
Description of drawings
Fig. 1 is the utility model cross section structure schematic diagram.
Wherein, 1-restrictive coating, 2-woven shield, 3-insulating barrier, 4-polyester film lapping layer, 5-conductor.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following example now, and be described with reference to the accompanying drawings as follows:
Embodiment
