Abstract
The utility model relates to a vertically watertight cable. The vertically watertight cable comprises core wires, insulation layers, insulating shielding layers and an oversheath, wherein the insulation layers are wrapped outside the cable wires, the insulating shielding layers are arranged outside the insulation layers, and the oversheath is arranged outside the insulating shielding layers. In the vertically watertight cable of the utility model, a hot melt adhesive is utilized for filling along the vertical direction of the cables, which is not only completely filled in gaps between the multiple core wires and the oversheath, but also filled in gaps between the core wires themselves and the insulation layers, thereby achieving a function of vertical and overall-length water resistance. The reliability of such filling technology in the utility model is obviously higher than current Occidental filling technologies of vertically watertight cables. Because the vertically watertight cable achieves the above purposes, the watertight cable can be ensured to work normally in the depth of 600 meter under water.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of direction waterproof cable.
Background technology
At present used cable is to be referred to as transverse sealing cable (cable of normal tape oversheath), and promptly the oversheath of cable is made intactly, reaches the infiltration of water when preventing that cable from using under water and destroys the transfer function of cable.Yet, when laterally watertight cable uses under water, receive the restriction of the pressure that the depth of water causes, can not be in darker laying under water and working; Because oversheath in case damage, can cause along the cable length direction will seep water in a large number and cause cable to burn out,, even cause device damage again like the infiltration access arrangement.
The direction waterproof cable mainly is the transmission cable that is applied to electric power conveying, control and the signal of naval vessels, ship for civil use, marine locator, ocean signal detection equipment etc.The present direction waterproof cable of American-European countries generally is to adopt a kind of powder that the cable internal voids is carried out packing.After cable has local damage, powder water-swellable and reach the purpose that blocks water.But the maximum defective of this technology is the infiltration that can not stop water fully, has a spot of water and infiltrates, and As time goes on can infiltrate in whole cables then.In the face of present situation, therefore necessary development adapts to the novel watertightness cable of modern technologies development level, improves the waterproof ability of cable, satisfies ocean engineering pressing for equipment build-up and development.
The utility model content
The utility model provides a kind of direction waterproof cable that increases submerged cable direction waterproof property.
For solving the problems of the technologies described above, the utility model direction waterproof cable comprises: heart yearn; Insulating barrier, said insulating barrier is wrapped in the outside of said heart yearn; Insulation screen, said insulation screen are arranged on the said insulating barrier outside; Oversheath, said oversheath is arranged on the outside of said insulation screen.
Said heart yearn is at least seven cores.Between said insulating barrier and the said heart yearn, between said insulation screen and the said insulating barrier, be filled with PUR between said oversheath and the said insulation screen.The material of said insulating barrier is a crosslinked polyethylene; The material of said oversheath is a polyvinyl chloride.
The utility model direction waterproof cable is to utilize a kind of PUR vertically to fill along cable; Not only the space that forms between cable inside multiply heart yearn and the oversheath is all filled; And; Fill in space to forming between heart yearn itself and the insulating barrier, with the effect that reaches vertically, overall length blocks water and infiltrates, and the direction waterproof cable filling technique that its reliability adopts apparently higher than present American-European countries.Because the direction waterproof cable of this programme development has reached above-mentioned purpose, cable operate as normal still in the time of can guaranteeing to reach under water 600 meters degree of depth.
Description of drawings
Fig. 1 is the utility model direction waterproof cross-section of cable sketch map;
Description of reference numerals in the utility model direction waterproof cable accompanying drawing:
1-heart yearn 2-insulating barrier 3-insulation screen
4-oversheath 5-PUR
Embodiment
Below in conjunction with accompanying drawing the utility model direction waterproof cable is done further explain.
As shown in Figure 1; The utility model direction waterproof cable; Comprise: coating hot-melt adhesive 5 on the heart yearn 1 of forming cable; Outside heart yearn 1, utilize Shooting Technique to coat crosslinked polyetylene insulated layer 2 then, guaranteeing does not have the gap between single heart yearn 1 and the crosslinked polyetylene insulated layer 2, and with heart yearn 1 and crosslinked polyetylene insulated layer 2 close adhesion one.At polyethylene layer 2 outside coating hot-melt adhesives 5, and superscribe insulation screen 3, then with the 1 mutual stranded stranding of the multiply heart yearn in the cable.PUR 5 is filled in space at rope-lay strand, superscribes polyvinyl chloride oversheath 4 at last.
The utility model direction waterproof cable is to utilize a kind of PUR vertically to fill along cable; Not only the space that forms between cable inside multiply heart yearn and the oversheath is all filled; And; Fill in space to forming between heart yearn itself and the sheath, with the effect that reaches vertically, overall length blocks water and infiltrates, and the direction waterproof cable filling technique that its reliability adopts apparently higher than present American-European countries.Because this direction waterproof cable reached above-mentioned purpose, cable operate as normal still in the time of can guaranteeing to reach under water 600 meters degree of depth.
The preferred embodiment of below the utility model having been created specifies; But the utility model is created and is not limited to said embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
