Description

一种抗严寒风力发电用电力电缆
技术领域
本发明属于电力电缆领域，具体是一种抗严寒风力发电用电力电缆。
背景技术
在全球能源日益紧张的今天，国家对可再生能源的需求不断增加，因此作为风力发电设备配套产品的低温风能电力电缆，正在成为有巨大市场潜力的电缆新品种，开发并投向市场。低温风能电力电缆广泛用于风能发电机转子的联接或用于塔内、外非移动电源的联接等，解决了设备安全运行的隐患，更新了环境效益，带来了经济效益。现有低温风能电力电缆的缺点为：在低于-55℃时绝缘、护套容易开裂造成短路，影响设备正常使用。
发明内容
本发明所要解决的技术问题是提供一种耐压性能好，耐腐蚀性能好，能抗严寒的风力发电用电力电缆。
本发明所述的一种抗严寒风力发电用电力电缆，包括缆芯，所述缆芯由一根芳纶加强元件和若干根绝缘线芯绞合而成，在缆芯内空隙处设有保温棉，在缆芯外套有聚氯乙烯绝缘管，在聚氯乙烯绝缘管绕包铝塑复合带，在铝塑复合带外挤包内护套，在内护套外编织非磁性钢丝加非磁性钢带金属结构的铠装层，在铠装层外设有交联聚乙烯外护套，最后，在交联聚乙烯外护套外挤包聚氨酯保温管。
所述绝缘线芯由无氧铜导体以及包覆在无氧铜导体外的交联聚乙烯绝缘管组成。
所述内护套包括腈纶纤维层、涤纶纤维层和连接层，所述连接层位于所述腈纶纤维层和涤纶纤维层中间并相互连接，所述中间层的材质为氯丁橡胶。
本发明的有益效果在于：
1、采用芳纶抗拉元件替代钢芯，不仅使得电缆的抗拉强度得到了很大的提高,而且柔韧性好,具有很好的抗氧化性与阻燃性能，而且断裂伸长率较小,不易发生变形。另外,芳纶材料的密度相比降低很多,相同抗拉强度要求下可大大降低电缆的重量。
2、填充采用保温棉，使得电缆的内部保温效果更好。
3、缆芯外设有聚氯乙烯绝缘管，使得电缆具有较好的抗拉、抗压强度。
4、绝缘线芯的绝缘采用交联聚乙烯绝缘管，代替了现有的一导体一绝缘的结构，不含增塑剂，不会霉变和滋生细菌，耐热性好，常规工作温度可达95℃，能够经受110℃环境下8000小时，耐压性能好，耐腐蚀性能好，能经受大多数化学药品的腐蚀，隔热效果好，节约能源，能够任意弯曲，不会脆裂，在同等条件下，水流量比金属管大，抗蠕变强度高，可配金属管，可省去连接管件，降低安装成本，加快安装周期，便于维修，交联聚乙烯管的重要特性在于其强度和耐温性能，特别是其蠕变强度，其强度随使用时间的变化不显著，寿命可达50年之久。
5、设有铝塑复合带，使得电缆具有更好的阻水性能。
6、采用非磁性钢丝加非磁性钢带金属铠装层结构形式，以达到很好的抗拉性、抗干扰性、使用寿命长等效果。
7、内护套各层之间结合强度高，耐雨水冲洗度好，多次清洗对防晒效果毫无影响，能有效抵御紫外线和光照，隔热效果优异，抗老化性强，一般普通的电缆抗老化是30年，本抗老化可达50年。
8、最外层设有聚氨酯保温管，保护了电缆的耐寒性，使得电缆具有强度高、耐冲击、耐环境老化预应力裂开、耐腐蚀、耐低温、易焊接、施工简便，严格密封无渗漏，还具有容重轻、强度高、绝热、隔音、阻燃、耐寒、防腐、不吸水、施工简便快捷等优异特点，另外，聚氨酯保温材料，适应温度为+120℃—-196℃，使得电缆在冰雪天气因结冰致使通信信号传输中断，造成无法挽救的经济损失。
