Abstract
The present invention relates to a cold resistant polyvinyl chloride sheath power cable. The cold resistant polyvinyl chloride sheath power cable comprises oxygen-free copper conductors, and insulating layers are arranged on the outsides of the oxygen-free copper conductors respectively. A low temperature resistant ammonia ester filling layer is arranged on the outside of the insulating layers, a cold resistant polyurethane cold resistant lapping layer is arranged on the outside of the flexible low temperature resistant ammonia ester filling layer, and a cold resistant polyvinyl chloride sheath layer is arranged on the outside of the cold resistant polyurethane cold resistant lapping layer. The cold resistant polyvinyl chloride sheath power cable of the present invention is high in stability, good in cold resistance and strong in flexibility.
Description
Technical field
The present invention relates to a kind of cable, be specifically related to a kind of power cable.
Background technology
Along with the development of science and technology, insulation and the sheath material of high-quality, high-tech content are developed, in addition the fast development of global economy, the diversity of use occasion also gets more and more, in order to be applicable to more and harsher use occasion, we used chlorinated polyethylene sheath cabtyre cable.Manufacture chlorinated polyethylene sheath cabtyre cable, solve the instability that common cable exists at present, anticorrosive property is poor, can not frequently movement, and creep-resistant property deficiency, the problems such as pliability is poor, not wear-resisting are effective methods.
Background technology
Along with use occasion require more and more higher, there is high-quality, the cold resistant cable of high-tech content is developed, we are vast in territory, and temperature great disparity is comparatively large, so use cold resistant cable to become inexorable trend at special occasions, cold resistant cable, solve the instability that common cable in the past exists, lower temperature resistance is poor, and use occasion is wide not, the problems such as pliability difference are effective methods.
Summary of the invention
Goal of the invention: the object of the invention is to overcome deficiency of the prior art, provide a kind of stability high, cold resistance is good, the cold resistance polyvinyl chloride sheath power cable that pliability is strong.
Technical scheme: in order to solve the problems of the technologies described above, a kind of cold resistance polyvinyl chloride sheath power cable of the present invention, it comprises oxygen-free copper conductor, insulating barrier is provided with outside described oxygen-free copper conductor, low temperature resistant ammonia ester packed layer is provided with outside described insulating barrier, outside described soft type low temperature resistant ammonia ester packed layer, be provided with cold-resistant polyurethane cold-resistant lapping layer, outside described cold-resistant polyurethane cold-resistant lapping layer, be provided with cold resistance polyvinyl chloride restrictive coating.
Described oxygen-free copper conductor is at least two.
Described low temperature resistant ammonia ester packed layer is soft type low temperature resistant ammonia ester packed layer.
Described low temperature resistant ammonia ester packed layer, cold-resistant polyurethane cold-resistant lapping layer and the cold-resistant layer of cold resistance polyvinyl chloride restrictive coating composition.
Beneficial effect: compared with prior art, its remarkable advantage is in the present invention: overall structure of the present invention is simple, packed layer, lapping layer, jacket portions adopt cold-resistant material, the every cold tolerance of effective raising, than common cable cold tolerance more stability, anticorrosive property is better, creep-resistant property is better, pliability is stronger, adopts oxygen-free copper conductor, effectively improves properties, more stable than fine copper, fine aluminium cable, conductivity is higher, this long product lifecycle, realistic instructions for use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, a kind of cold resistance polyvinyl chloride sheath power cable of the present invention, it comprises oxygen-free copper conductor 1, insulating barrier 2 is provided with outside described oxygen-free copper conductor 1, low temperature resistant ammonia ester packed layer 3 is provided with outside described insulating barrier 2, outside described soft type low temperature resistant ammonia ester packed layer 3, be provided with cold-resistant polyurethane cold-resistant lapping layer 4, outside described cold-resistant polyurethane cold-resistant lapping layer 4, be provided with cold resistance polyvinyl chloride restrictive coating 5; Described oxygen-free copper conductor 1 is at least two; Described low temperature resistant ammonia ester packed layer 3 is soft type low temperature resistant ammonia ester packed layer; Described low temperature resistant ammonia ester packed layer 3, cold-resistant polyurethane cold-resistant lapping layer 4 and cold resistance polyvinyl chloride restrictive coating 5 form cold-resistant layer 6.Overall structure of the present invention is simple, and packed layer, lapping layer, jacket portions adopt cold-resistant material, effectively improve every cold tolerance, than common cable cold tolerance more stability, anticorrosive property is better, and creep-resistant property is better, and pliability is stronger, adopt oxygen-free copper conductor, effective raising properties, more stable than fine copper, fine aluminium cable, conductivity is higher, this long product lifecycle, realistic instructions for use.
The invention provides a kind of thinking and method; the method and access of this technical scheme of specific implementation is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, some improvements and modifications can also be made; these improvements and modifications also should be considered as protection scope of the present invention, and all available prior art of each part not clear and definite in the present embodiment is realized.
