Abstract
The invention discloses a three-core photoelectric composite submarine cable with 220kV rated voltage. The cable is characterized by comprising an outer layer, an armor layer and a lining layer which are distributed from outside to inside in turn, wherein three electrical units in which every two units are externally tangential to each other are arranged in the lining layer; a plurality of filling units are filled in three gaps which are enclosed by the electrical units and the lining layer; the three electrical units and all the filling units are stranded into a submarine cable main core part; a gluing cloth tape is lapped outside the stranded submarine cable main core part; and at least one of all the filling units is an optical unit, and the rest filling units are filling ropes. The invention has the advantages that: the three-core photoelectric composite submarine cable with the 220kV rated voltage has a balanced phase during use, does not have requirements on armoring materials, can prevent the magnetic loss of the armor layer and improves the effective utilization rate of power; and the occupied sea area is greatly reduced compared with that of a single-core submarine cable with the same specification.
Description
Technical field
The present invention relates to a kind of cable, relate 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 is mainly due to 110kV and above single electric unit Heavy Weight, size is large, as adopt three core manufacturings to technology, equipment and the material etc. of cables manufacturing process require high, difficulty is large.
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 three cores seas cables with equal-specification, three single core sea cables need to take the larger area marine site.
Summary of the invention
Technical problem to be solved by this invention is to provide 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 present invention solves the problems of the technologies described above the technical scheme that adopts: 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 electric units that two two-phases are circumscribed in described inner covering, three gaps, place that described electric unit and described inner covering surround all are 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 extra large cable master core segment after stranded, in all filler cells, wherein at least one is the light unit, remaining filler cells is gasket for packing.
The material of described gasket for packing is 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 semiconductive MDPE(medium density polyethylene).
Three described electric units surround center gap place is 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, advantage of the present invention is the three core photoelectric composite submarine cables phase equilibrium in use of this rated voltage 220kV, armoring material is not required, can not cause the magnetic loss of armour, improved the availability of electric power, and shared oceanic area is than greatly reducing with the extra large cable of single core of equal-specification; The single-core cable of the ceiling voltage level maximum cross-section of using at present in addition, 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.
