Abstract
The utility model relates to a kind of waterproof cable, comprise jacket layer, the inwall of described jacket layer is provided with water blocking tape layer, the inwall of water blocking tape layer is provided with interior jacket layer, the inside of interior jacket layer is provided with some equally distributed conductors, the outer wall of conductor is provided with one deck insulating case, filling cotton layer between the outer wall of insulating case and interior jacket layer.Waterproof cable reasonable in design of the present utility model, arranges water blocking tape layer, after water enters oversheath between jacket layer and interior jacket layer, the material of water blocking tape layer is met water and is just expanded, stop moisture to spread further along cable, therefore there is good waterproof action, extend the useful life of cable.
Description
Technical field
The utility model relates to a kind of waterproof cable.
Background technology
Along with the fast development of power industry, data communication industry, urban track traffic industry etc., the requirement of all trades and professions to cable is more and more higher, in use, not only will avoid that cable is mechanically damaged, insulation harm, ageing of insulation are rotten, also humidified insulation will be avoided, i.e. waterproof.Under normal conditions, cable is often laid in ground or have the place of water, due to the permeability of cable sheath material, or cable cover(ing) is by mechanical damage, water enters cable inside, and cause the interior formation water tree that insulate, water tree is constantly oxidized, cause the destruction to insulation, this substantially reduces the life-span of cable.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of waterproof cable.
Waterproof cable of the present utility model, comprise jacket layer, the inwall of described jacket layer is provided with water blocking tape layer, the inwall of water blocking tape layer is provided with interior jacket layer, the inside of interior jacket layer is provided with some equally distributed conductors, the outer wall of conductor is provided with one deck insulating case, filling cotton layer between the outer wall of insulating case and interior jacket layer.
Compared with prior art the beneficial effects of the utility model are: waterproof cable reasonable in design of the present utility model, between jacket layer and interior jacket layer, water blocking tape layer is set, after water enters oversheath, the material of water blocking tape layer is met water and is just expanded, moisture is stoped to spread further along cable, therefore there is good waterproof action, extend the useful life of cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of waterproof cable described in the utility model embodiment.
In figure:
1, jacket layer; 2, water blocking tape layer; 3, interior jacket layer; 4, conductor; 5, insulating case; 6, cotton layer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of waterproof cable, comprise jacket layer 1, the inwall of described jacket layer 1 is provided with water blocking tape layer 2, the inwall of water blocking tape layer 2 is provided with interior jacket layer 3, the inside of interior jacket layer 3 is provided with some equally distributed conductors 4, and the outer wall of conductor 4 is provided with one deck insulating case 5, filling cotton layer 6 between the outer wall of insulating case 5 and interior jacket layer 3.
Waterproof cable reasonable in design of the present utility model, arranges water blocking tape layer, after water enters oversheath between jacket layer and interior jacket layer, the material of water blocking tape layer is met water and is just expanded, stop moisture to spread further along cable, therefore there is good waterproof action, extend the useful life of cable.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
