Description

一种碳纤维材质电线电缆
技术领域
本发明涉及电力输送技术领域，尤其涉及一种碳纤维材质电线电缆。
背景技术
现有的电缆，一般采用镀锌钢丝作为线芯，外层绞合圆形的铝合金线。这种电缆主要存在以下几方面的问题：一、由于外层绞合的是圆形的铝合金线，导致线与线之间的间隙大，有效截面积小，且外径大，储存和运输过程中占用空间大。二、由圆形的铝合金线绞合形成的外层表面凹凸不平、不光滑，容易堆积冰雪或其他负重物质，增加电缆的负重，抗冰雪能力差，容易压弯破坏电缆。三、所用镀锌钢丝的抗拉强度低，重量大，架设时跨距较小，架设电缆所需的杆塔数量多，不但成本大，浪费人力物力，而且占用土地资源多。
基于以上问题，现有的电缆已无法满足电力建设快速发展的新需求。
发明内容
本发明的目的是为了克服现有技术的不足，提供了一种碳纤维材质电线电缆。
本发明是通过以下技术方案实现：
一种碳纤维材质电线电缆，包括由碳纤维复合芯形成的导体芯层，所述的导体芯层由内到外依次包括有硬铝圆线绞合层、碳纤维包覆层、绝缘导热层、限位护套和外护套；
所述硬铝圆线绞合层、碳纤维包覆层和绝缘导热层设置在限位护套内；
所述外护套包括由内向外的PET塑料绕包带，绕包带外包裹有金属丝编织网，金属编织网外包裹有橡胶保护套；
所述限位护套和外护套之间的空隙内设有氧化镁填充物。
进一步的，所述碳纤维包覆层的一端设置有交直流变换器。
进一步的，所述限位护套为软质塑料。
进一步的，所述的硬铝圆线绞合层为3股硬铝圆线绞合而成。
进一步的，所述导体芯层包括一根碳纤维复合芯。
与现有的技术相比，本发明的有益效果是：利用碳纤维复合芯绞合形成的导体芯层，提高了架空输电电缆的抗拉强度，且重量轻，可实现大跨距架空并且提高了载流量，架空输电电缆所需的杆塔数量减少，大大降低了人力物力等成本，并且土地资源少；限位护套的设置加强了电缆之间的稳定性，避免电缆的位移；并且外护套上的金属丝编织网大大加强了电缆的抗老化能力，从而延长了使用寿命。
附图说明
图1为本发明的结构示意图。
图中：1、硬铝圆线绞合层；2、碳纤维包覆层；3、绝缘导热层；4、限位护套；5、外护套。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参阅图1所示的一种碳纤维材质电线电缆，包括由碳纤维复合芯形成的导体芯层，所述的导体芯层由内到外依次包括有硬铝圆线绞合层1、碳纤维包覆层2、绝缘导热层3、限位护套4和外护套5；
所述硬铝圆线绞合层1、碳纤维包覆层2和绝缘导热层3设置在限位护套4内；加强了电缆之间的稳定性，避免电缆的位移。
所述外护套5包括由内向外的PET塑料绕包带，绕包带外包裹有金属丝编织网，金属编织网外包裹有橡胶保护套；金属丝编织网大大加强了电缆的抗老化能力，延长使用寿命。
所述限位护套4和外护套5之间的空隙内设有氧化镁填充物。
其中，所述碳纤维包覆层2的一端设置有交直流变换器；交直流变换器上还可以连接漏电保护器和温控器。
其中，所述限位护套4为软质塑料，所述的硬铝圆线绞合层1为3股硬铝圆线绞合而成，所述导体芯层包括一根碳纤维复合芯。
与传统的同类产品相比，本发明的碳纤维复合电缆可满足大截面高压、特高压线路的建设，减少了电力在传输中的损耗，提高了电力传输效率。
本发明的碳纤维复合电缆利用碳纤维复合芯绞合形成的导体芯层，从而提高了架空输电电缆的抗拉强度，且重量轻，可实现大跨距架空并且提高了载流量，架空输电电缆所需的杆塔数量减少，大大降低了人力物力等成本，并且土地资源少；限位护套的设置加强了电缆之间的稳定性，避免电缆的位移；并且外护套上的金属丝编织网大大加强了电缆的抗老化能力，从而延长了使用寿命。
