Abstract
The utility model discloses a single core submarine cable, include the conductor that blocks water that strands into the art by many conductor single lines, the interior gap filling within a definite time of the conductor that blocks water there is the electrically conductive glue that blocks water, the conductor from interior to exterior that blocks water has set gradually conductor shield, insulating layer, insulation screen, semi -conductive water -blocking tapes, semiconduction rent water cushion layer, the plumbous cover of alloy, restrictive coating and armor, the nested iron shielded layer that is provided with between semi -conductive water -blocking tapes and the semiconduction rent water cushion layer, the internal surface and the surface of armor have the mekralon layer around the package respectively. The utility model discloses the conductor that blocks water makes the gap between the conductor filled up by the conducting resin that blocks water completely through adopt filling the conducting resin that blocks water, effectively plays the effect of vertically blocking water, plays the effect that well blocks water in the sea water, have resistance to wear, corrosion -resistant, long service life, reliable and stable advantage.
Description
Technical field
This utility model relates to field of cable technology, particularly relates to a kind of single submarine cable.
Background technology
Sea electric power cable is owing to being arranged on the seabed of circumstance complication, affected by sea beat, seawater corrosion and many X factors for a long time, its design, manufacture and installation requirement are all significantly larger than common cable, and sea electric power cable has been largely fixed the length in its service life for the effect quality blocked water.
Chinese patent literature CN104409153A discloses a kind of high filling high water resistant cable, including cable core and the protective jacket 8 being coated on outside described cable core, described cable core is the conductor that some electric units are intertwined, and described electric unit includes metal bare wire 6, is coated on the waterstop 3 outside described metal bare wire 6 and ethylene propylene rubber insulated layer 7 the most successively.The most in the structure shown here firstly the need of being coated with waterstop 3 outside metal bare wire, it is coated with ethylene propylene rubber insulated layer 7 the most again, uses this structure, every metal bare wire to be required for being coated with operation through twice before stranded, the integral diameter that the program easily causes cable is thicker, and processing cost rises.
Summary of the invention
For the problems referred to above, this utility model provides a kind of wear-resistant, corrosion-resistant, and service life is long, stability and the high single submarine cable of reliability.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of single submarine cable, including the water-blocking conductor being twisted into art by many conductor single lines, gap in described water-blocking conductor is filled with conduction and blocks water glue, described water-blocking conductor is disposed with conductor shield from the inside to the outside, insulating barrier, insulation screen, semiconductor waterstop, semiconductive rents water subfill, alloy lead set, restrictive coating and armor, described semiconductor waterstop and semiconductive are rented nesting between water subfill and are provided with metal screen layer, the inner surface of described armor and outer surface are rotating around being surrounded by polypropylene fibre layer.
Further, described insulating barrier is crosslinked polyethylene.
Further, described armor is that almag steel wire is wrapped to be formed, the loop configuration that the cross section of described almag steel wire is distributed in same periphery.
From the above-mentioned description to this utility model structure, compared to the prior art, this utility model has the advantage that
1, this utility model water-blocking conductor is filled the conducting resinl that blocks water make the gap between conductor be filled up by the conducting resinl that blocks water completely by being used, effectively play longitudinal water-blocking effect, compared with traditional water-blocking conductor, the higher requirement that blocks water can be met, play the effect well blocked water in the seawater.
2, this utility model uses the wrapped armor of magnesium alloy steel wire, and at armor inner surface and outer surface rotating around being surrounded by polypropylene fibre layer, wear-resistant, corrosion-resistant, it is ensured that the service life of submarine cable, stability and reliability are high.
