Abstract
The utility model discloses a waterproof flexible cable, which comprises more than one copper conductor. An insulating layer is respectively extruded outside each copper conductor, a filling layer isarranged outside the insulating layer, a winding layer is arranged outside the filling layer; and a sheath layer is arranged outside the winding layer. The waterproof flexible cable has the advantagesthat by adopting the insulating layer with ethylene-propylene insulating mixture and good insulating property, the maximum long-term operating temperature of the cable is improved to 90 DEG C, the current-carrying capacity of the cable is greatly improved, the water-absorption added value of an AC capacitor of the material is small, after being immersed in the water at 50 DEG C, the water-absorption added value of the AC capacitor is less than 15% through the comparison at the end of the fourteenth day and at the end of the first day. The sheath layer with the waterproof sheath material and higher compactness is additionally arranged, so that the end product cable can smoothly pass the two-hour horizontal sealing hydrostatic test under the water pressure of 3040Pa; as the filling layer and the winding layer with non-absorbent material are added, the cable has better waterproof performance, thereby greatly improving the service life and safety of the cable.
Description
Technical field
The utility model relates to a kind of waterproof flexible cable of technical field of electric wires and cables, the waterproof flexible cable of particularly a kind of rated voltage 450/750V and following fountain device-specific.
Background technology
At present, fountain equipment vertically water inlet phenomenon often occurs with the common rubber sleeve flexible cable of the many employings of cable in the use, cause insulation resistance decline, thereby influences the useful life of cable.The ac capacitor suction increment of insulation is big, and the highest long-term permission working temperature of conductor is 65 ℃; The permission minimum bending radius of cable is 6 times the outside diameter of cable when laying.This series products can not satisfy the waterproof requirement of fountain equipment with cable, and this type of current-carrying capacity of cable is little, can not satisfy the requirement of fountain equipment with cable.
The utility model content
Goal of the invention: utility model technical problem to be solved provides a kind of good electric property, rated voltage 450/750V and following fountain device-specific waterproof flexible cable that water resistance is superior.
Technical scheme: the utility model discloses a kind of waterproof flexible cable, comprise the copper conductor more than, outside every copper conductor, extrude, outside insulating barrier, be provided with packed layer, outside packed layer, be provided with lapping layer, outside lapping layer, be provided with restrictive coating by insulating barrier.
In the utility model, preferably, described insulating barrier is made by second third insulation compound.
In the utility model, preferably, described packed layer is filled for the waterproof rubber and is made.
In the utility model, preferably, described lapping layer is made by polyester belt.
In the utility model, preferably, described restrictive coating is made by the haloflex compound.
Beneficial effect: the utility model has the advantages that and adopt the insulation property second third insulation compound insulating barrier preferably, make the highest long-term work temperature of this cable bring up to 90 ℃, the ampacity of cable improves greatly, and the ac capacitor of this material suction increment is less, ac capacitor hygroscopicity value after 14 days in immersing 50 ℃ of water, the contrast of the ac capacitor hygroscopicity value when immersing in 50 ℃ of water 1 day, the ratio that the former increases than the latter is less than 15%.Added the higher water-proof jacket material restrictive coating of compactness, finished cable can be 3040Pa by hydraulic pressure smoothly, and 2 hours the transverse sealing hydraulic test more owing to added non-absorbent material packed layer and lapping layer, makes this cable have the better waterproof energy.The useful life and the fail safe of cable have been improved so greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done further and to be specified.
Be illustrated as the utility model waterproof flexible cable cross section structure schematic diagram.
Embodiment
As shown in the figure, present embodiment is that example illustrates execution mode of the present utility model with rated voltage 450/750V and following fountain device-specific flexible cable three-core cable.On three copper conductors 1, all extrude the insulating barrier 2 that one deck is made by second third insulation compound.The packed layer 3 that is made is filled in filling by the waterproof rubber between each insulating barrier.The lapping layer of making by polyester belt at packed layer 3 peripheral wrapped one decks 4.On lapping layer 4, extrude the oversheath 5 that one deck is made by waterproof haloflex compound.
The utility model provides a kind of thinking and method of waterproof flexible cable; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a 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 improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
