Abstract
The utility model provides a low-temperature-resistant cable comprising a conductor, a polyimides insulating layer, an insulation shielding layer, a heat-insulation layer, a steel band armoring layer and an outer sheath layer arranged in sequence from inside-out; firstly the polyimides insulating layer extrudes or wraps outside the conductor, and then the insulation shielding layer, the heat-insulation layer, the steel band armoring layer and the outer sheath layer are arranged in sequence from inside-out; the outer sheath layer is a low-smoke halogen-free polyolefin sheath layer; and the heat-insulation layer is prepared by heat-insulation cotton. The low-temperature-resistant cable arranges the polyimides insulating layer on the conductor and adds the heat-insulation layer prepared by the heat-insulation cotton in the outer sheath, thereby enabling the cable to well suit usage requirements in a low-temperature or an ultralow temperature environment; and the cable is simple in structure, low in cost and good in usage effect.
Description
Technical field
The utility model relates to cable, particularly a kind of low temperature resistant cable.
Background technology
Along with the development of society, the importance of cable grows with each passing day.From using on the industry, cable has almost all obtained extensive use in all trades and professions such as power industry, communication industry, track traffic industries; From using on the region, there are not the four corners of the world of branch and climate difference, all be used for cable.This just requires cable not only temperature capacity will be arranged, and also needs to possess low temperature resistant low power.At present more to fire-resistant, the high temperature resistant research of cable, and pay close attention to not enough to the low temperature resistant particularly limit of cable low temperature.Some the time, when common cable used at a lower temperature, phenomenons such as outer jacket cracking even cable breakage appearred in regular meeting, have a strong impact on normal power supply.
The utility model content
The purpose of this utility model is: overcome the deficiencies in the prior art, provide a kind of resistance to low temperature good, can be under low temperature even limit low temperature still can normal power supply low temperature resistant cable.
The technical solution of the utility model is: low temperature resistant cable of the present utility model, comprise conductor, and its design feature is: also comprise polyimide insulative layer, insulation screen, heat-insulation layer, steel-tape armouring layer and external sheath layer; Above-mentioned polyimide insulative layer extrudes or is wrapped behind conductor, and insulation screen, heat-insulation layer, steel-tape armouring layer and external sheath layer are provided with successively from inside to outside again.
Further preferred version is: above-mentioned external sheath layer is the low-smoke halogen-free polyolefin restrictive coating; Heat-insulation layer is the heat-insulation layer that heat-preservation cotton is made.
The utlity model has positive effect: low temperature resistant cable of the present utility model, by polyimide insulative layer is set on conductor, set up the heat-insulation layer that heat-preservation cotton is made again in the oversheath simultaneously, thereby can adapt to the use needs of low temperature even ultra-low temperature surroundings preferably, and it is simple in structure, cost is not high, and result of use is better.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Reference numeral in the above-mentioned accompanying drawing is as follows:
Conductor 1, polyimide insulative layer 2, insulation screen 3, heat-insulation layer 4, steel-tape armouring layer 5, external sheath layer 6.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
(embodiment 1)
See Fig. 1, the low temperature resistant cable of present embodiment, by conductor 1, polyimide insulative layer 2, insulation screen 3, heat-insulation layer 4, steel-tape armouring layer 5, external sheath layer 6 is formed.
Conductor 1 is copper linear part, and its cross section is circular.
Polyimide insulative layer 2 extrudes or is wrapped on conductor 1, constitutes insulated wire cores with conductor 1.
Insulation screen 3 wrapped peripheries in polyimide insulative layer 2.
Preferred employing heat-preservation cotton is filled and is formed in heat-insulation layer 4 present embodiments.It has insulation effect preferably.Heat-insulation layer 4 is arranged on the periphery of insulation screen 3.
Steel-tape armouring layer 5 is arranged on the periphery of heat-insulation layer 5.
The material of external sheath layer 6 selects for use low smoke and zero halogen environment-friendly polyolefin fire proofing to make, and external sheath layer 7 is coated on the periphery of steel-tape armouring layer 5.
The low temperature resistant cable of present embodiment is owing to be provided with polyimide insulative layer on conductor, set up the heat-insulation layer that heat-preservation cotton is made again in the oversheath simultaneously, thereby can adapt to the use needs of low temperature even ultra-low temperature surroundings preferably, and simple in structure, cost is not high, and result of use is better.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is under the situation that does not break away from spirit and scope of the present utility model; can also make various conversion and variation and obtain the corresponding technical scheme that is equal to, so all technical schemes that are equal to all should be included into scope of patent protection of the present utility model.
