Abstract
The invention relates to an anticorrosive submarine cable capable of radially and vertically blocking water. The cable comprises a plurality of water-blocking conductors, wherein semiconductive water-blocking lapping belts 1, internal shielding layers, insulation layers, external shielding layers, copper belt shielding layers and semiconductive water-blocking lapping belts 2 are sequentially arranged outside the conductors from inwards to outwards so as to form a plurality of insulation cores which jointly extrude and wrap an internal water-blocking belt so as to form cable cores, an aluminum plastic vertical wrapping belt, a middle water-blocking belt, a PE internal sheath, a steel armour layer, an external water-blocking belt, a PE external water-blocking layer and a fiber outer serving layer are sequentially arranged outside the cable cores from inwards to outwards so as to form cable bodies; a water-blocking yarn is arranged between the insulation cores and the internal water-blocking belt for filling. The submarine cable disclosed by the invention is compact in structure, can prevent submarine corrosion, is strong in outside force resistance, good in pressure resistance, good in water-blocking performance, and long in service life.
Description
Technical field
The present invention relates to a kind of submarine cable, particularly relate to a kind of anticorrosive, footpath longitudinal water-blocking submarine cable.
Background technology
The restriction people of the factors such as Marine Geology inclement condition, environment are changeable, corrosive properly is strong fail to complete preferably ocean development, but the domestic cable seldom possessing footpath longitudinal water-blocking performance, this cable is mainly used in the strong marine environment of ocean deep-etching, High Voltage, high infiltration, mechanical stress, for better developing marine resources.
Summary of the invention
The present invention provides a kind of compact conformation, anti-seawater corrosion to overcome the above problems, external force resistance ability is strong, anti-pressure ability good, anticorrosive, the footpath longitudinal water-blocking submarine cable of long service life.
Technical scheme of the present invention is: described cable comprises some water-blocking conductors, described conductor sets gradually semiconductive outward from the inside to the outside and to block water twining package tape one, internal shield, insulating barrier, outer shielding layer, copper strip shielding layer and the semiconductive twining package tape two that blocks water forms insulated wire cores, described some insulated wire cores jointly extrude interior waterstop and form cable core, described cable core sets gradually plastic-aluminum outward from the inside to the outside and indulges band, middle waterstop, PE inner sheath, steel wire armor layer, outer waterstop, the outer water blocking layer of PE and fiber serving form cable body, be provided with water blocking yarn between described some insulated wire cores and interior waterstop to fill.
Described water-blocking conductor is pressed layer by layer by category-B compact conductor and forms, and innermost layer conductor is vertical bag one deck single-sided insulation waterstop outward, wrapped single-sided insulation waterstop between every layer of conductor.
Described internal shield and outer shielding layer are semiconductive shielding layer.
Described insulating barrier is XLPE water resistant tree insulating barrier.
Compact conformation of the present invention, anti-seawater corrosion, external force resistance ability is strong, anti-pressure ability good, block-water performance is good, long service life.
