Abstract
The utility model discloses a novel cold-resistant cable. The cable comprises a jacket layer, a filling layer, an insulation layer and a copper conductor wire. The copper conductor wire is coated by the insulation layer. The cable further comprises a heat absorption and heat conduction layer. The heat absorption and heat conduction layer is tightly coated by the jacket layer. The filling layer disposed between the insulation layer and the heat absorption and heat conduction layer. The cable utilizes the silicone rubber insulating layer or the fluoroplastic insulating layer, and the silicone rubber jacket layer or the fluoroplastic jacket layer that are difficult to fracture in low temperature conditions, so that low temperature resistant capability of the cable is improved, the heat absorption and heat conduction layer has a good heat absorption function, a high heat efficiency, and a long service lifetime, and is safe and reliable.
Description
Technical field
The utility model relates to cable technology field, is specifically related to a kind of novel cold resistant cable.
Background technology
Along with the increasing in mankind's activity field, the range of application of cable is also progressively strengthening.Particularly also increase gradually in the use of extremely frigid zones cable, this just requires cable will have very strong cold resistance, thereby cable is run more secure, reliable at extremely frigid zones.At present, widely used cold resistant cable conductor is under the microthermal climate of burst, and potential safety hazard, appears in the phenomenon that there will be insulation and sheath hardening, the generation that becomes fragile is ftractureed.Therefore make cable have cold tolerance, cold district is better used the technical barrier that becomes field of cables more simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of novel cold resistant cable, and this cable has good pliability under low temperature environment, and can long-term safety operation under the microthermal climate of burst.
In order to address the above problem, the utility model is realized in the following manner:
A kind of novel cold resistant cable, comprise restrictive coating, packed layer, insulating barrier and copper conductor line, described copper conductor line is wrapped with insulating barrier, also comprises heat absorption conductive layer, described heat absorption conductive layer is extruded with restrictive coating outward, and described packed layer is between insulating barrier and heat absorption conductive layer.
Described heat absorption conductive layer adopts high heat-conduction polyurethane insulating material to make.
Described restrictive coating is silicone rubber jacket layer or fluoroplastics restrictive coating.
Described insulating barrier is silicone rubber insulation layer or fluoroplastic insulation layer.
Preferably, described packed layer adopts high-strength tensile type polyester yarn.
Compared with prior art, the beneficial effects of the utility model: this cable is by selecting silicone rubber insulation layer or fluoroplastic insulation layer and silicone rubber jacket layer or fluoroplastics restrictive coating, under cryogenic conditions, be not easy cracking, improve the low temperature tolerance ability of cable, heat absorption conductive layer has good heat absorption function, the heat efficiency is high, long service life, safety, reliable.
