Description

一种高性能低压侧电缆
技术领域
本发明属于电力输送设备技术领域，具体涉及一种高性能低压侧电缆。
背景技术
电缆通常是由几根或几组导线(每组至少两根)绞合而成的类似绳索的电缆，每组导线之间相互绝缘，并常围绕着一根中心扭成，整个外面包有高度绝缘的覆盖层。多架设在空中或装在地下、水底，用于电讯或电力输送。1832年，沙俄退伍军官许林格将电报线路埋在地下，六根导线之间彼此用橡胶绝缘后同放在玻璃管内，这就是世界上最早的一条地下电缆。电缆按其用途可分为电力电缆、通信电缆和控制电缆等。与架空线相比,电缆的优点是线间绝缘距离小,占地空间小，地下敷设而不占地面以上空间，不受周围环境污染影响，送电可靠性高，对人身安全和周围环境干扰小。但造价高，施工、检修均较麻烦，制造也较复杂。
现有技术的低压侧电缆存在以下问题：1、随着社会现代化的高速发展，低压侧电缆也就变得越粗越重，对低压侧电缆的要求越来越高，这是需要解决的大问题，如何使低压侧电缆在大跨距的空间更有效合理布置，使变压器发挥更大的功能，已成为电力行业面临的问题；2、不具有高强度、耐低温弯曲、柔软、环保等特性，其使用寿命较短。
发明内容
为解决上述背景技术中提出的问题。本发明提供了一种高性能低压侧电缆，具有高强度、柔软和环保等特点。
为实现上述目的，本发明提供如下技术方案：一种高性能低压侧电缆，包括软铜导体、绝缘套、接地线、加强芯和外护套，所述外护套的内部设置有两个相互对称绝缘套，所述绝缘套的内部均设置有软铜导体，两个所述绝缘套之间设置有接地线和加强芯，所述接地线安装在加强芯的一侧，所述接地线和加强芯均安装在外护套的内部。
优选的，所述绝缘套的材料为交联聚烯烃，交联聚烯烃通过125℃无卤低烟阻燃辐照。
优选的，所述接地线的材料为镀锡软铜，所述接地线的直径为1.2cm。
优选的，所述加强芯的材料为芳纶编织物，所述加强芯的直径为2.0cm。
优选的，所述外护套的材料为CPE橡胶，CPE橡胶材料通过低烟无卤阻燃辐照。
优选的，所述软铜导体的外表面设置有镀锡层，所述软铜导体的直径为1.8cm。
与现有技术相比，本发明的有益效果是：
1、本发明的导体采用超柔软镀锡软铜丝，便于变压器低压侧安装，在保证线缆外护强度的情况下增加线缆柔软性能，软铜导体中间增加一根芳纶编织加强芯，重量小，还可以增强低压侧电缆整体强度，适合大跨距施工。
2、本发明的绝缘套为交联聚烯烃材料，交联聚烯烃材料通过125℃无卤低烟阻燃辐照，具有优良的耐候、耐高温，耐振动、耐油、耐辐射，增加低压侧电缆使用寿命，同时125℃无卤低烟阻燃外护套在火灾中不会出现有毒有害气体，保证人身安全。
