Description

一种耐用电力电缆
技术领域
本发明涉及一种耐用电力电缆。
背景技术
现有的电力电缆在电力行业中应用广泛，行业的应用范围涉及的地区也比较多，不仅在城市中需要电力电缆进行输电配电，城乡一体化进程中，乡村的覆盖面积也在增大，然而乡村地区中还有很多的地方处于贫困落后地区，环境比较差，这就很大程度上影响了电气设备的应用，传统的电力电缆在技术上还无法适应一些恶劣的环境，因为在耐磨性能和电力电缆的弹性方面还存在很大差距，这样就加大了勘察力度，检修频繁耗费了大量的人力物力，同时另一方面乡村泥泞，灰尘石块摩擦多，下了雨之后还经常有积水，为了增大安全系数，需要提高电力电缆抗耐磨性和防水性能。
现有的三相电力电缆存在一个很大的缺陷就是A相、B相、C相导线都是圆柱形，这样各相之间容易滑动摩擦，时间久了，容易出现各相之间短路。
发明内容
本发明要解决的技术问题是提供一种设计简单、安全性高、抗拉性能强、抗磨性能强和防水性能高的耐用电力电缆。
为解决上述技术问题，本发明采用如下技术方案：
一种耐用电力电缆，包括有电缆主体，所述电缆主体设置有五层，由外到内分别是保护层、圆钢丝铠装层、阻水层、第一屏蔽层和第一绝缘层，所述保护层内部设置有一条以上的抗拉绳，所述第一屏蔽层设置有三层，由外到内分别是第一铜丝网层、铝层和第二铜丝网层，所述第一绝缘层内部设置有固定支架和三根导体，所述固定支架固定连接三根导体，所述固定支架呈三角形设置，所述导体上设置有第二绝缘层，所述第二绝缘层上设置有第二屏蔽层，所述固定支架由按重量份数配比的尖晶石20‐24份、页岩20‐22份、莫来石18‐20份、钛酸酯10‐12份、硅藻土18‐20份、竹炭16‐18份、镁砂10‐12份、碳化硅16‐18份、丙烯酸树脂14‐16份、苯二甲酸二丁酯10‐14份、硼酸锌12‐16份、醋酸乙烯酯10‐16份、硅酸钾14‐18份、聚硅氧烷12‐16份和冰醋酸16‐18份制成。
进一步的，所述第一绝缘层内部设置有一条以上的加强筋，提高了电缆的强度。
进一步的，所述保护层与圆钢丝铠装层之间设置有荧光层，当电缆磨损严重时，晚上会出现荧光，可以及时修复电缆，提高安全性。
进一步的，所述保护层外表面设置有刻度，利于计算电缆长度。
进一步的，所述抗拉绳与保护层为一体化设置，使电缆的结构更加紧凑和稳固。
进一步的，所述保护层表面设置有防水膜，提高了电缆的防水性能。
固定支架的制造方法，包括有以下步骤：
1)取尖晶石20‐24份、页岩20‐22份和莫来石18‐20份，送入破碎机中制成颗粒，再送入气流粉碎机中制成粒径为100nm‐200nm的粉末，备用；
2)将硅藻土18‐20份送入粉碎罐中，采用物理的方法，通入高压气体、通过气流的作用，硅藻土在粉碎灌中进行撞击，进行粉碎，备用；
3)将步骤2)中硅藻土粉末送入负离子搅拌器中，负离子搅拌器中释放正离子，硅藻土释放负离子，通过正负离子之间的吸附作用，形成硅藻泥，备用；
4)取竹炭16‐18份送入气流粉碎机中制成粉末，送入加热器中，加入钛酸酯10‐12份、丙烯酸树脂14‐16份和苯二甲酸二丁酯10‐14份，温度升至80‐100℃，持续1‐2小时，备用；
5)取镁砂10‐12份、碳化硅16‐18份、醋酸乙烯酯10‐16份和硅酸钾14‐18份，送入高速搅拌机中，搅拌均匀，再送入加热器中，温度升至50‐60℃，持续20‐30min，备用；
