Abstract
The utility model aims to provide a low-temperature-resistant cable. The low-temperature-resistant cable is characterized by sequentially comprising conductors, an insulation inner sheath, and an outer sheath from interior to exterior; and an insulation layer is arranged between the outer sheath and the insulation inner sheath. Due to the design of the insulation layer, the low-temperature-resistant cable can be insulated, and cannot be frozen easily; and the damage of freezing to the cable can be reduced. The low-temperature-resistant cable has a simple structure, common insulation cotton is used as the insulation layer, the low-temperature-resistant cable is light in weight, and the gravity of the cable cannot be increased. The low-temperature-resistant cable is simple in structure, low in cost, and suitable for various transmission lines and has a good effect.
Description
Technical field
The utility model relates to a kind of cable, specifically relates to a kind of low temperature resistant cable.
Background technology
Development along with power industry, data communication industry, urban track traffic industry etc.; All trades and professions require increasingly highly to cable, in use, not only will avoid cable to receive mechanical damage, insulation harm, ageing of insulation rotten etc.; Also under cryogenic conditions, use, promptly low temperature resistant.Existing transmission line does not have winterized equipment, and one to winter, snows or rain on transmission line, to freeze easily, breaks electric wire, causes large-area power-cuts.Sometimes even cause short circuit to cause fire, be absolutely unsafe.
The utility model content
The purpose of the utility model is to overcome above-mentioned technical problem, and a kind of low temperature resistant cable is provided.
Concrete technical scheme is following:
A kind of low temperature resistant cable is characterized in that, is followed successively by conductor, insulation inner sheath, oversheath from the inside to the outside, is provided with heat-insulation layer between oversheath and the insulation inner sheath.
Preferably, said heat-insulation layer is that heat-preservation cotton is filled the heat-insulation layer that forms.
The low temperature resistant cable of the utility model adopts the heat-insulation layer design, owing to be provided with heat-insulation layer, can realize electric wire self insulation, and is not-easy-to-freeze, reduced the electric wire that brings because of freezing and damaged.The utility model is simple in structure, selects for use general heat-preservation cotton to make heat-insulation layer, and light weight can not increase the gravity of electric wire self.The utility model is simple in structure, and cost is low, and is effective, is fit to various transmission lines.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1-conductor, the 2-inner sheath that insulate, 3-heat-insulation layer, 4-oversheath.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
A kind of low temperature resistant cable is followed successively by conductor 1, insulation inner sheath 2, oversheath 4 from the inside to the outside, is provided with heat-insulation layer 3 between oversheath 4 and the insulation inner sheath 2.Said heat-insulation layer 3 is filled the heat-insulation layer 3 that forms for heat-preservation cotton.
At last, it is also to be noted that what more than enumerate only is the practical implementation example of the utility model, obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought the protection range of the utility model.
Claims (2)
1. a low temperature resistant cable is characterized in that, is followed successively by conductor, insulation inner sheath, oversheath from the inside to the outside, is provided with heat-insulation layer between oversheath and the insulation inner sheath.
2. low temperature resistant cable according to claim 1, said heat-insulation layer are that heat-preservation cotton is filled the heat-insulation layer that forms.
