Abstract
The invention relates to a watertight control cable. The watertight control cable comprises conductors, vertical watertight layers, insulation layers, vertical watertight filling, watertight wrapping and a radial watertight sheath layer which are sequentially arranged from inside to outside, wherein each conductor is wrapped by one vertical watertight layer. According to the watertight control cable, a vertical and radial integrated watertight structure can effectively prevent water from immersing into the watertight control cable, effectively prolongs service life of the watertight control cable and reduces maintenance cost of the watertight control cable.
Description
[technical field]
The present invention relates to a kind of control cable that blocks water.
[background technology]
Fast development along with electric power system, traffic system, cable extensively is used in occasions such as harbour, hydroelectric station, river-crossing tunnel, moist rainy zone such as south particularly, cable usually will be in wet environment steady operation, this just has higher requirement to the block-water performance of cable.
Tradition control cable is answered the use of material and structure, block-water effect is very poor, along with the cable growth of running time, moisture is just invaded insulating barrier, insulating barrier will form electric branch under the effect of alternating electric field, when electric branch ran through whole insulating barrier, cable breakdown was scrapped, and increased maintenance cost and the security risk of cable virtually.
[summary of the invention]
Technical problem to be solved by this invention is: a kind of novel control cable that blocks water is provided, remedies the block water defective of aspect of existing control cable, can reach superior block-water effect from radially and vertical integrated water stop.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of control cable that blocks water, comprise the conductor that sets gradually from inside to outside, vertically water blocking layer, insulating barrier, vertically block water fillings, block water wrapped, reach the restrictive coating that radially blocks water, described vertical water blocking layer is wrapped outside conductor.
Compared with prior art, integrated water stop structure vertical and radially of the present invention can prevent effectively that moisture from immersing cable inside, has effectively prolonged the useful life of cable, has reduced the maintenance cost of control cable.

Conductor 1 blocks water and controls cable 100
Vertical water blocking layer 2 insulating barriers 3
The filling 4 that blocks water blocks water wrapped 5
Restrictive coating 6 radially blocks water
Following embodiment will further specify the present invention in conjunction with above-mentioned accompanying drawing.
[embodiment]
As shown in Figure 1, be the control cable 100 that blocks water according to the invention.
The control cable 100 that blocks water comprise the conductor 1 that sets gradually from inside to outside, vertically water blocking layer 2, insulating barrier 3, vertically block water fill 4, wrapped 5, the restrictive coating 6 that blocks water radially blocks water.The described control cable 100 that blocks water comprises three cables, and every cable comprises conductor 1, is enclosed in the vertical water blocking layer 2 outside the conductor 1 and is enclosed in vertical water blocking layer 2 insulating barrier 3 outward.Block water and wrapped 5 surround three cables, the restrictive coating 6 that radially blocks water surrounds and blocks water wrappedly 5, vertically blocks water and fills 4 between adjacent two cables.Conductor 1 adopts a class conductor or the high compact conductor of two classes, reduces the slit between the conductor monofilament as far as possible, avoids moisture to invade.Vertically water blocking layer 2 is wrapped outside conductor 1, and vertically water blocking layer 2 can absorb storage moisture, and the energy imbibition, fills up the slit between insulating barrier 3 and the conductor 1, stops moisture further to immerse cable conductor 1, reaches vertical block-water effect.Insulating barrier 3 adopts cross-linking polyethylene materials, and its fine and close molecular structure also has certain water stop function.Vertically block water and fill 4 and block water and wrapped 5 adopt water blocking yarn respectively and the lapping layer that blocks water, this is water, can fill up the space between the cable core after the expansion, reaches vertical block-water effect.Radially block water restrictive coating 6 for the outer compound stop water of high-density polyethylene plastics of interior plastic-aluminum band, bond together closely through aluminium-plastic tape behind the extruder and high density polyethylene (HDPE), reach the effect that radially blocks water.
Adopt suitable conductor 1 according to the GB/T3956 regulation in conjunction with the actual conditions conductor, adopt a class and the high compact conductor of two classes, conductor should be bright and clean, phenomenons such as no burr, overlap.The vertical water blocking layer 2 of the conductor 1 overlapping wrapped individual layer in surface, Duplication is not less than 25%.Extrude cross-linked polyethylene insulating material on the plastic extruder, can not occur coming unstuck, bad phenomenon such as bottom pour ladle, flake.Enter cross-linking process after extruding, increase temperature resistant grade and the useful life of cable.Select suitable cabler to carry out stranding, the direction of stranding is dextrad.The stranding lay ratio will comply with relevant regulations, and the speed of each parts also will be followed the pertinent regulations of operation card.Vertically block water and fill 4 employing water blocking yarns, the space of stranding is filled up, keep the rounding property of cable.Wrapped 5 the direction of blocking water is left-hand, adopts to put up wrappedly, puts up size and is 25% of twining package tape width, and wrapping angle is 25 ° to 40 °.Restrictive coating 6 radially blocks water, interior is the aluminum plastic composite belt longitudinal covering, outer is the high density polyethylene (HDPE) restrictive coating, aluminium-plastic tape has not allowed bad phenomenon such as joint, gauffer, breakage, after high density polyethylene (HDPE) is extruded, bond together closely with aluminium-plastic tape, reach radially block-water effect, high density polyethylene (HDPE) extrude extruding with insulating barrier.
Compared with prior art, integrated water stop structure vertical and radially of the present invention can prevent effectively that moisture from immersing cable inside, has effectively prolonged the useful life of cable, has reduced the maintenance cost of control cable.
