An oil platform seabed water-blocking composite power transmission cable, including a cable core provided with wires and water-blocking filling ropes, the wires are two wire groups with different voltage levels and different specifications; the outer conductor of each wire in the low-voltage wire group Coating insulation layer, the outer conductor of each wire of the high-voltage wire group is coated with conductor shielding layer, intermediate insulation layer, insulation shielding layer, semi-conductive resistance water tape layer, and metal shielding layer; Plastic composite tape layer, inner sheath, metal armor layer, outer sheath, tape layer. The conductor of the cable wire adopts a double-layer structure: the central layer conductor is twisted with multiple strands of copper wire coated with water-blocking grease, and then covered with a semi-conductive resistance water tape layer in the central layer; the outer layer conductor is coated with multiple strands The copper wire of the water-blocking ointment is coated on the outside of the semiconductive resistance hose layer of the central layer, and then wrapped on the outer semiconductive resistance hose layer. The utility model has the composite function of power transmission with different voltage levels, and one cable can be used for both purposes, saving investment; the cable has good water blocking performance and high strength, and can meet the use requirements of the power cable used on the seabed for offshore oil platforms.
Description
Technical field
The utility model relates to a kind of power cable, especially the sea electric power cable of used for oil platform.
Background technology
Existing offshore oil platform subsea power transmission cable function singleness, block-water performance is lower, and insufficient strength is difficult to adapt to the instructions for use that offshore oil platform is used for the power cable in seabed.
Summary of the invention
The purpose of this utility model provides a kind of oil platform seabed complex function, that block-water performance is good, intensity is high composite electric transmission cable that blocks water that has, to adapt to the instructions for use that offshore oil platform is used for the power cable in seabed.
The oil platform seabed that the utility model the provides composite electric transmission cable that blocks water comprises the cable core that is provided with lead and blocks water gasket for packing, and lead is the lead group of two different electric pressures, different size; The conductor outsourcing insulating layer coating of every lead of low-voltage lead group, the conductor of every lead of high voltage lead group be coating conductor screen, intermediate insulating layer, insulation screen, semiconductive water blocking tape layer, metal screen layer successively outward; Metallized aluminum plastic composite strip layer, sheath, metal armouring layer, outer jacket, belting layer successively outside cable core.
In order to strengthen block-water performance of the present utility model, conductor of the present utility model adopts double-decker: the central core conductor coats central core semiconductive water blocking tape layer again with stranded the forming of copper wire of multiply coating greasy for preventing water; Outer contact is coated on outside the central core semiconductive water blocking tape layer with the copper wire that multiply applies greasy for preventing water, coats outer semiconductive water blocking tape layer again.
The beneficial effects of the utility model are: have the complex function of the electric power transfer of different electric pressures, a cable is dual-purpose, reduces investment outlay; The block-water performance of cable is good, intensity is high, can adapt to the instructions for use that offshore oil platform is used for the power cable in seabed.
