Abstract
The utility model discloses a longitudinally-sealed waterproof flexible cable. The longitudinally-sealed waterproof flexible cable includes regularly-twisted longitudinally-sealed compound flexible conductors, a polyolefin/rubber composite insulation layer, a tinned copper-braided armoring layer, a heat-sealed aluminum/plastic composite tape longitudinally-wrapped waterproof layer and a poly ethylene (PE) radial waterproof jacket layer which are arranged from outside to inside sequentially. According to the longitudinally-sealed waterproof flexible cable of the utility model, the insulation layer is boned with the conductors through hot melt adhesive, so it can be ensured that water and air do not flow along the axial direction of the conductors; the exterior of the insulation layer is wrapped with the tinned copper-braided armoring layer and is coated with a sealant so as to be sealed, such that pressure resistance and mechanical strength can be improved; and the exterior of the braided armoring layer is provided with the heat-sealed aluminum/plastic composite tape and is pressingly wrapped with a poly ethylene (PE) outer jacket layer, such that the radial waterproof jacket layer can be formed, and therefore, the water will not penetrate the cable jacket along an axial direction to enter the cable jacket when the cable is subjected to horizontal water pressure. When a fractured surface of the cable is subjected to water pressure, the water will not flow in the cable along an axial direction, and when the cable is subjected to horizontal water pressure, the water will not penetrate the cable jacket along an axial direction to enter the cable jacket, and therefore, the longitudinally-sealed waterproof flexible cable has great application value and market prospects.
Description
Technical field:
The utility model relates to a kind of water-proof cable, particularly relates to the longitudinal sealing waterproof flexible cable that a kind of energy satisfies the requirement of higher hydraulic pressure lower seal.
Background technology:
Vertically waterproof sealing---be exactly when the section of cable is subject to hydraulic pressure, gas pressure, section is mobile vertically within it to stop water, gas.
Laterally waterproof---when cable was subject to Water Pressure, water can not enter cable inside along radially passing cable cover(ing) exactly.
Cable conductor has the space by tangent stranded the forming of cylinder single line between the single line, also have the gap between conductor and the insulation; When the cable cross section was subject to larger pressure, as not taking effective protection, aqueous vapor just flowed along the gap between them, the impact extremely dangerous on the security performance generation of cable.Existing waterproof technique is to fill the materials such as waterproof yarn, waterproof powder and waterproof between conductor, although can play certain resistance effect, under larger pressure, air-tightness can not satisfy actual requirement.
All macromolecular materials have water absorption in various degree, particularly water penetration is particularly serious in larger hydraulic pressure situation, alone macromolecular material is as overcoat, under high pressure can not play effective waterproof effect, moisture can see through restrictive coating enter cable inside, and the usage safety performance of cable is worked the mischief.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of longitudinal sealing waterproof flexible cable is provided, guarantee that water, gas is not along the conductor axial flow.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of longitudinal sealing waterproof flexible cable includes from the inside to surface successively: regular stranded vertical glue sealed composite flexible conductor, Polyolefin and rubber composite insulating barrier, tin-coated copper braiding armour, heat seal aluminum plastic composite belt longitudinal packaging waterproof layer and PE be the water-proof jacket layer radially.
Described regular stranded vertical glue sealed composite flexible conductor and Polyolefin and rubber composite insulating barrier are by the PUR bonding together, described Polyolefin and rubber composite insulating barrier and tin-coated copper braiding armour by the PUR bonding together, described heat seal aluminum plastic composite belt longitudinal packaging waterproof layer and PE radially water-proof jacket layer are in the same place by hot melting cohesion.
Positive beneficial effect of the present utility model is as follows:
1, the utility model conductor adopts regular lay configuration, and direction of lay ectonexine direction is consistent, identical with bundle strand direction, insulating barrier adopts water proof type polyolefin and rubber combined, insulating barrier and conductor dbus are crossed PUR and are bonded together, insulating barrier and conductor are combined closely, and guarantee that water, gas is not along the conductor axial flow.
2, the utility model carries out tin-coated copper braiding armour and applies simultaneously fluid sealant sealing for improving voltage endurance capability and mechanical strength outside insulating barrier; When preventing that cable is subject to horizontal hydraulic pressure, water can radially not pass cable cover(ing) and enter its inside, outside the braiding armour heat seal aluminium-plastic tape is set and extrudes PE outer jacket bonding to form radially water-proof jacket layer.
3, the utility model has realized that the cable section is under the 3.5MPa Water Pressure, vertically water-tight, air tight under 2 hours, 3 meters experimental conditions of cable length, pressure is unchanged, cable 72 hours insulating surfaces under the 4.0MPa Water Pressure keep dry, do not have moisture to see through cable cover(ing) to enter cable inside, reach the cable seal waterproof effect.
4, the utility model solved cable section be subject under the Water Pressure water not within it section flow vertically
Moving technical problem has solved when cable is subject under the horizontal Water Pressure water and can radially not pass cable cover(ing) and enter its inner technical problem, has good using value and marketing prospect.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Referring to Fig. 1, a kind of longitudinal sealing waterproof flexible cable includes from the inside to surface successively: regular stranded vertical glue sealed composite flexible conductor 1, Polyolefin and rubber composite insulating barrier 2, tin-coated copper braiding armour 3, heat seal aluminum plastic composite belt longitudinal packaging waterproof layer 4 and PE be water-proof jacket layer 5 radially.Regular stranded vertical glue sealed composite flexible conductor 1 bonds together by PUR with Polyolefin and rubber composite insulating barrier 2, Polyolefin and rubber composite insulating barrier 2 and tin-coated copper braiding armour 3 by the PUR bonding together, heat seal aluminum plastic composite belt longitudinal packaging waterproof layer 4 and PE radially water-proof jacket layer 5 are in the same place by hot melting cohesion.
This utility model has solved cable and has been subject to the not technical problem that flows vertically of section within it of water under the Water Pressure at section, solved when cable is subject under the horizontal Water Pressure water and can radially not pass cable cover(ing) and enter its inner technical problem, had good using value and marketing prospect.
