Description

一种抗拉架空电缆结构
技术领域
本发明涉及一种电缆，尤其涉及一种抗拉架空电缆结构。
背景技术
随着经济发展，各行各业对电缆的要求越来越高，由于传输的需要通常要把电缆架在高空，所以需要高电压，高强度、大跨越的架设电缆，通常要求这类电缆要有极高的抗拉强度以及抗风、耐寒等特性。目前的架空电缆都采用金属加强芯或者加强筋提高电缆的抗拉强度， 这样导致电缆的重量较重，并且由于此类电缆在高空中架设，其安全性能往往低于其他类电力电缆。再者纯铜导芯电缆由于铜资源较匮乏，易受国际市场的影响，且重量较重，在运输和现场施工等方面都比较不便。
因此，为解决上述问题，特提供一种新的技术方案。
发明内容
本发明提供一种抗拉架空电缆结构。
本发明采用的技术方案是：
一种抗拉架空电缆结构，由内至外依次包括缆芯、绕包层、绝缘层和外护套层，所述缆芯由多束导芯构成，每束导芯均由铜包铝导体和抗拉纤维绞合而成，多束导芯外部包裹有绕包层，所述绕包层与多束导芯的空隙处设有填充体，所述外护套层内侧壁设有若干凸起块，所述绕包层与绝缘层之间设有编织层，所述编织层与外护套层之间设有防水层。
进一步的，所述绝缘层采用交联聚乙烯材料。
进一步的，所述填充体呈管束状。
进一步的，所述编织层由镀锌铜制成。
进一步的，每束导芯由一根铜包铝导体和两根抗拉纤维绞合而成，每束导芯之间平行设置，每束导芯与填充体之间平行设置。
本发明的有益效果是：结构简单，导芯采用铜包铝导体和抗拉纤维绞合而成有效降低了电阻系数，提高了载流量并且增强了抗张力强度，同时空隙处采用填充体进行填充，有效地提高了电缆的抗拉性能，安全系数高，采用编织层、防水层和外护套相结合的结构方式，增强了电缆的防水、阻燃性，提高了电缆的稳定性。
