一种阻燃耐高温电力电缆
技术领域
本发明涉及电气设备领域，尤其涉及一种阻燃耐高温电力电缆。
背景技术
电气设备包括一次设备和二次设备，电缆属于电气设备中的二次设备。随着我国经济的不断发展，电缆的应用范围越来越广，其性能要求也越来越高。传统的电缆耐热性能差，在发生火灾时，容易发生燃烧，影响电力传输的同时，扩大了火灾的蔓延趋势，不能有效保障公民的生命财产安全。上述问题亟需解决。
发明内容
基于背景技术存在的技术问题，本发明提出了一种阻燃耐高温电力电缆，以解决上述技术问题。
本发明提出的一种阻燃耐高温电力电缆，包括：缆芯、绕包层、屏蔽层、阻燃层和外护套；缆芯包括一根第一线芯和多根第二线芯，第一线芯位于所述缆芯中部，其具有圆形截面，第一线芯包括第一导体和包覆在第一导体外部的第一绝缘层，第二线芯具有扇环形截面，其平行纵置，第二线芯的内弧面与第一线芯相抵，第二线芯之间通过平直面相抵，并使所述缆芯具有圆形截面，第二线芯包括第二导体和包覆在第二导体外部的第二绝缘层，玻璃纤维带绕包在所述缆芯外部形成绕包层，钢丝铜丝编织绕包在绕包层外周形成屏蔽层，陶瓷硅橡胶挤包在屏蔽层外周形成阻燃层，低烟无卤聚乙烯挤包在阻燃层外周形成外护套。
本发明提出的一种阻燃耐高温电力电缆，第一线芯和第二线芯的布置放置充分利用了电缆的内部空间，其结构紧凑，在受到外力时，缆芯不易发生移动；玻璃纤维带耐热性强、抗腐蚀性好，机械强度高，绕包在缆芯外部，提高了电缆的耐高温性能和机械强度，延长了使用寿命，降低计算机电缆绝缘老化的风险；陶瓷硅橡胶耐高温，拉力强度好，在遇到明火时，其燃烧形成坚硬的氧化层，防止火势向缆芯内部蔓延，提高了电缆的阻燃性能；外护套可防止外界热量进入电缆内，进一步提升了电缆的耐高温性能。本发明提出的一种阻燃耐高温电力电缆，结构紧凑，具备良好的耐高温性能和阻燃性能。
附图说明
图1为本发明提出的一种阻燃耐高温电力电缆的结构示意图。
具体实施方式
如图1所示，图1为本发明提出的一种阻燃耐高温电力电缆的结构示意图。
参照图1，本发明提出的一种阻燃耐高温电力电缆，包括：缆芯、绕包层3、屏蔽层4、阻燃层5和外护套6；缆芯包括一根第一线芯1和多根第二线芯2，第一线芯1位于所述缆芯中部，其具有圆形截面，第一线芯1包括第一导体11和包覆在第一导体11外部的第一绝缘层12，第二线芯2具有扇环形截面，其平行纵置，第二线芯2的内弧面与第一线芯1相抵，第二线芯2之间通过平直面相抵，并使所述缆芯具有圆形截面，第二线芯2包括第二导体21和包覆在第二导体21外部的第二绝缘层22，玻璃纤维带绕包在所述缆芯外部形成绕包层3，钢丝铜丝编织绕包在绕包层3外周形成屏蔽层4，陶瓷硅橡胶挤包在屏蔽层4外周形成阻燃层5，低烟无卤聚乙烯挤包在阻燃层5外周形成外护套6。
本方案中的第一线芯1和第二线芯2的布置放置充分利用了电缆的内部空间，其结构紧凑，在受到外力时，缆芯不易发生移动；玻璃纤维带耐热性强、抗腐蚀性好，机械强度高，绕包在缆芯外部，提高了电缆的耐高温性能和机械强度，延长了使用寿命，降低计算机电缆绝缘老化的风险；陶瓷硅橡胶耐高温，拉力强度好，在遇到明火时，其燃烧形成坚硬的氧化层，防止火势向缆芯内部蔓延，提高了电缆的阻燃性能；外护套6可防止外界热量进入电缆内，进一步提升了电缆的耐高温性能。
本方案中的外护套6沿其长度方向开设有多个散热孔7，电缆工作产生的热量可通过所述散热孔7向外部传导，进一步提高了电缆的耐高温性能。
此外，阻燃层5内设有多根吸热管8，吸热管8内填设有冷却剂，可吸收来自电缆内外的热量，更进一步提高了电缆的耐高温性能。
