Abstract
The utility model relates to a water-blocking conductor for submarine cables. The water-blocking conductor comprises a center single wire and a plurality of layers of outer single wires which are stranded in layers around the center single wire, wherein the stranding direction of the adjacent two layers of the outer single wires are opposite to each other; the gaps among the single wires are filled with a water-blocking paste, the extreme layer of the single wires is coated with two semi-conductive water-blocking tapes. The water-blocking paste is used and the extreme layer of the single wires is coated with the semi-conductive water-blocking tapes, so that the vertical water blocking performance is greatly improved, and compared with the common water blocking structure, the electrical and mechanical properties of the conductors are obviously improved.
Description
Technical field
The utility model belongs to the cable technology field, relates generally to submarine cable conductor longitudinal water-blocking technology, is applicable to the production of various middle high-low pressure submarine cables.
Background technology
Sea electric power cable is mainly used in transmitting high-power power under water, with the effect of land power cable, is equal to, and only the occasion of application is different with the mode of laying.Submarine cable is owing to being immersed in for a long time in seawater, therefore higher than overland cable to the requirement that blocks water, and when particularly cable sustains damage, blocks water and does not reach requirement, will cause the big-length cable to be scrapped, and causes heavy losses.
The structure of the water-blocking conductor that existing submarine cable is used generally has: waterstop structure, waterstop and the various ways such as water blocking yarn structure, water blocking yarn structure, but in actual use, block-water effect still awaits further raising.
Summary of the invention
The utility model is the block water requirement very high for submarine cable, and a kind of submarine cable longitudinal water-blocking conductor is provided, and by conductor structure is improved, makes its block-water performance reach large increase.
For realizing the object of the invention, the utility model adopts following technical scheme:
A kind of submarine cable water-blocking conductor, comprise the center single line and around center single line stranded outer single line from level to level; Two adjacent two-layer strands of described outer single line are on the contrary.When described product adjacent layer is stranded, every layer of single line filled waterproof paste in gap, and the outermost layer single line is surrounded with two-layer semiconductive waterstop outward.
This conductor is stranded belongs to regular stranded, starts stranded process from the second layer and adopts certain coefficient 0.90～0.98 that presses, and improve as far as possible skin and press coefficient, and internal layer presses coefficient can suitably be reduced, to reduce gap.Recharge waterproof paste between gap, increase the conductor block-water performance.By the water blocking test of various structures, record various Data Comparisons and analysis, adopt the comprehensive structure block-water effect of waterproof paste and waterstop more satisfactory.Not only the longitudinal water-blocking performance has obtained very large lifting, and conductor electric property and mechanical property have also had obvious improvement than other stop waters commonly used.
The above structure of visible employing, because submarine cable is immersed in seawater for a long time, when particularly cable sustains damage, the raising of longitudinal water-blocking performance is conducive to reduce cable and scraps length, to repair work, races against time, and avoids causing heavy losses.
the accompanying drawing explanation:
fig. 1 is structural representation of the present utility model.
In figure: 1, center single line; 2, waterproof paste; 3, semiconductive waterstop; 4, outer single line.
Embodiment
Referring to Fig. 1, this submarine cable comprise Yi Gen center single line 1 with water-blocking conductor and around the center single line by regular stranded mode stranded outer single line 4 from level to level.Strand between adjacent every one deck of outer single line is to all contrary.Start stranded process from the second layer and adopt that to press coefficient be 0.90～0.98, and should improve as far as possible skin and press coefficient, internal layer and outerly press the difference of coefficient between 0～0.1.Fill waterproof paste 2 between gap, increase the conductor block-water performance.Finally at the wrapped two-layer semiconductive waterstop 3 of outermost layer.
The outer wrapped semiconductive waterstop of the waterproof paste that this structure adopts is by after existing material water-proof material and the improvement of existing technology, carries out the lot of experiments contrast and obtains the best mode that blocks water of block-water effect.
Claims (2)
1. a submarine cable water-blocking conductor, comprise the center single line and around center single line stranded outer single line from level to level, and two adjacent two-layer strands of described outer single line are on the contrary; It is characterized in that: every layer of single line filled waterproof paste in gap, and the outermost layer single line is surrounded with two-layer semiconductive waterstop outward.
2. submarine cable water-blocking conductor according to claim 1 is characterized in that: from inside to outside, the outer single line of ground floor adopts that to press coefficient be 0.90～0.98, and skin presses coefficient and raises gradually, internal layer and outerly press the difference of coefficient between 0～0.1.
