Abstract
The utility model discloses a flexible waterproof cable comprising a cable core formed by twisting a plurality of insulation wire cores; waterproof ropes are filled in gaps of the cable core; an outer sheath is extruded on an outermost layer of the cable; two double-surface waterproof belt layers are repeatedly wrapped between the cable core and the outer sheath; and a wrinkle metal sheath is arranged outside the double-layer double-surface waterproof belts. Three insulation wire cores are provided, and each wire core is formed by a conductor, and an insulation layer and a waterproof belt both extruded outside the conductor. Waterproof ropes attached with waterproof paste are employed to fill gaps in a cabling process, so vertical waterproof capacity is provided for the cable; two double-surface waterproof belt layers are repeatedly wrapped outside the cable core, and repeat covering rate of each layer is bigger than or equal to 25%; the wrinkle metal sheath is employed outside the cable core waterproof belt; the flexible waterproof cable is good in bending performance and is provided with radial waterproof capacity; if water penetrates the metal sheath, the waterproof belts and the waterproof ropes can be fast expanded to stop the water from further penetrating in the cable; and the flexible waterproof cable is suitable to be applied in navigation industry in our nation.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of flexible water repellent electric cable.
Background technology
At present, the structure that water repellent electric cable mainly adopts is at the overlapping wrapped waterstop in cable core outside, or protect the principle that blocks water as cable in the employing polyethylene, the cable of this structure can not be immersed in the water work for a long time, and particularly the ship of navigation operation, fleet etc. are in the process of carrying out freight handling.Because unexpected, cable is subject to the effect of mechanical force, the outer jacket of cable might be damaged, water or moisture will immerse cable inside from breakage, then to the infiltration of cable two ends, reduce the insulation resistance of cable, its electrical property is descended, finally affect the useful life of cable.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly conducts electricity very well, flexibility is good, water preventing ability is good, the flexible water repellent electric cable of long service life.
A kind of flexible water repellent electric cable described in the utility model comprises cable core, and its cable core is by stranded the forming of some eradication edge cores; Gap at cable core is provided with waterproofing rope, and the cable outermost layer extrudes oversheath, and overlapping wrapped two-layer two-sided waterstop adopts corrugated metallic sheath outside the double-layer and double-side waterstop between cable core and oversheath.
Further improve, described insulated wire cores is three, and every by conductor and be extruded in conductor outer insulating barrier, waterstop and consist of.
Further improve, described water blocking layer is the waterproofing rope with waterproof paste again.
The beneficial effects of the utility model:
Compared with prior art, adopt with the waterproofing rope of waterproof paste during the utility model stranding and fill, this has guaranteed that cable has the longitudinal water-blocking ability, overlapping wrapped two-layer two-sided waterstop outside cable core, the overlapping rate of putting up of every one deck is not less than 25%, corrugated metallic sheath is adopted in cable core waterstop outside, its bending property is better, and has a radial water-resisting ability, when in case metallic sheath is crossed in water logging, under waterstop effect and the rapid ability that expands of waterproofing rope, stoped again the further infiltration of moisture to cable inside.Extrude the layer of polyethylene oversheath in the metallic sheath outside, this plastic sheath also has certain water-resisting ability, and can protect corrugated metallic sheath to avoid the effect of mechanical damage again.Therefore should have vertically and the ability of radial water-resisting by the flexibility water repellent electric cable, be adapted at humidity or have the place of water to use, especially be applied on the seafaring of China.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of flexible water repellent electric cable described in the utility model comprises cable core, and its cable core is by stranded the forming of some eradication edge cores; Described insulated wire cores is three, and every by conductor 1 and be extruded in conductor 1 outer insulating barrier 2, waterstop 3 and consist of.Be provided with water blocking layer 4 in the gap of cable core, the waterproofing rope that its water blocking layer 4 adopts with waterproof paste; The cable outermost layer extrudes oversheath 7, and overlapping wrapped two-layer two-sided waterstop 5 between cable core and oversheath 7 is at double-layer and double-side waterstop 5 outer employing corrugated metallic sheaths 6.
The utility model provides a kind of thinking and implementation method of flexible water repellent electric cable; concrete application approach is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
