Abstract

The utility model discloses a three-core opto-electric composite submarine cable with a rated voltage 220kV, characterized in sequentially comprising an outer layer, an armored layer and an inner lining layer from outside to inside, wherein the inner lining layer is provided with three electric units pairwise externally tangent, three gaps surrounded by electric units and the inner lining layer are each filled with multiple filling units, the three electric units and all filling units are intertwisted to form a strand of submarine cable main core portion, the intertwisted submarine cable main core portion is wrapped with a rubberized cotton tape, at least one of all the filling units is an optical unit, and the others are filling ropes. The three-core opto-electric composite submarine cable with a rated voltage 220kV is in phase balancing when used, has no requirements for the armoring material, and causes no hysteresis loss of the armoring layer, the effective use rate of the power is improved, and the occupied marine area is greatly reduced compared with three single core submarine cables having the same specification.

Description

Rated voltage 220kV three core photoelectric composite submarine cables
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of rated voltage 220kV three core photoelectric composite submarine cables.
Background technology
Rated voltage 110kV and above cable (comprising extra large cable and land cable) all adopt single cored structure at present, this mainly is because 110kV and above single electric unit Heavy Weight, size is big, as adopts three core manufacturings big to requirement height such as technology, equipment and material, the difficulty of cables manufacturing process.
And the armoring material of single-core cable generally do not adopt magnetic material, otherwise can cause the circuit magnetic loss of armour, reduces the availability of electric power; In addition, compare with the three cores sea cable of equal specification, three single core sea cables need take the larger area marine site.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of rated voltage 220kV three core photoelectric composite submarine cables that improve the availability of electric power and can reduce the oceanic area occupancy.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: rated voltage 220kV three core photoelectric composite submarine cables, comprise the outer layer that drapes over one's shoulders that distributes successively from outside to inside, armour and inner covering, be provided with three two electric units that two-phase is circumscribed in the described inner covering, the gap, three places that described electric unit and described inner covering surrounded all is filled with a plurality of filler cells, three described electric units and all whole stranded formation one stock market cable master core segments of filler cells, be surrounded with the gluing strap outside the extra large cable master core segment after stranded, wherein at least one is the light unit in all filler cells, and remaining filler cells is a gasket for packing.
The material of described gasket for packing is a modified polymer material.
Described modified polymer material is modified polypropene (PP), modified poly ethylene (PE) or modified polyvinyl chloride (PVC).
Described electric unit comprises conductor, conductor shield, insulating barrier, insulation screen, water-blocking buffer layer, lead alloy cover and the inner sheath that distributes successively from inside to outside.
The material of described inner sheath is a semiconductive MDPE(medium density polyethylene).
Three center gap places that described electric unit surrounded are filled with the Split Down gasket for packing, and described Split Down gasket for packing and described electric unit twist together.
Compared with prior art, the three core photoelectric composite submarine cables that the utility model has the advantages that this rated voltage 220kV are phase equilibrium in use, armoring material is not required, can not cause the magnetic loss of armour, improved the availability of electric power, and shared oceanic area significantly reduces than the extra large cable of single core of equal specification; In addition, the single-core cable of the ceiling voltage level maximum cross-section of using at present is 500kV 3000mm 2, its outside diameter of cable is no more than 190mm, weight is no more than 45kg/m, and the external diameter 〉=250mm of three core submarine cables of the present invention, weight 〉=100kg/m.
Description of drawings
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, rated voltage 220kV three core photoelectric composite submarine cables, comprise the outer layer 1 that drapes over one's shoulders that distributes successively from outside to inside, armour 2 and inner covering 3, be provided with three two electric units that two-phase is circumscribed in the inner covering 3, electric unit comprises the conductor 7 that distributes successively from inside to outside, conductor shield 8, insulating barrier 9, insulation screen 10, water-blocking buffer layer 11, lead alloy cover 12 and inner sheath 13, the gap, three places that electric unit and inner covering 3 are surrounded all is filled with a plurality of filler cells, three center gap places that electric unit surrounded are filled with Split Down gasket for packing 14, three electric units, Split Down gasket for packing 14 and all whole stranded formation one stock market cable master core segments of filler cells, be surrounded with gluing strap 4 outside the extra large cable master core segment after stranded, in all filler cells wherein two be light unit 5, remaining filler cells is a gasket for packing 6.
In the foregoing description, the material of gasket for packing 6 is a modified polymer material, as modified polypropene, modified poly ethylene or modified polyvinyl chloride etc.; The material of inner sheath 13 is semiconductive MDPE, and conductor shield 8 is made up of semiconductive band and the semi-conductive layer that extrudes, and the material of insulating barrier 9 is crosslinked polyethylene (XLPE), and the material of armour 2 is a zinc-coated wire.
