一种交联聚乙烯绝缘聚烯烃护套无卤低烟阻燃电力电缆
技术领域
本发明涉及电力电缆技术领域，尤其涉及一种交联聚乙烯绝缘聚烯烃护套无卤低烟阻燃电力电缆。
背景技术
随着我国社会发展进步，高层建筑、大型商场等建筑物不断增多，用电量不断提高，如果采用低压供电，在电缆用量、敷设安装工作量及敷设空间用量等都需要很大投入，因此，逐步采用中压供电降低成本是电力行业发展的必然趋势。近几年，为了提高电气线路的安全等级，减少电气火灾事故的发生及损失，国家建设部、公安部以及一些地方政府相继出台了一些电气设计规范，而低烟无卤电缆由于具有燃烧时烟密度小，透光率高，无卤酸气体放出，无有害副产物等优点，因此得到广泛的应用，但是，市场上出现的大多数电力电缆难免会存在散热效果不佳、强度较低等缺点导致电力电缆使用寿命较低，针对以上不足，我们推出一种交联聚乙烯绝缘聚烯烃护套无卤低烟阻燃电力电缆，来代替旧式的电力电缆，满足人们的生活需求。
发明内容
本发明的目的是为了解决现有技术中存在散热效果不佳、强度较低的缺点，而提出的一种交联聚乙烯绝缘聚烯烃护套无卤低烟阻燃电力电缆。
为了实现上述目的，本发明采用了如下技术方案：

优选的，所述支撑四棱台是由硬度较高的橡胶材料制成，所述支撑四棱台的内部均设有空腔。
优选的，所述加强层等角度固定设有多个加强钢丝，所述加强钢丝为直径长度2mm的镀锌钢丝。
优选的，所述无卤低烟内护套层和隔热层相接触的表面设有多个齿槽。
优选的，所述第一防水层、多个支撑四棱台和第二防水层之间形成水冷却通道。
优选的，所述填充层是由无碱玻璃纤维材料制成。
优选的，所述隔热层是由无卤聚烯烃材料制成。
优选的，所述第一防水层和第二防水层均是由防水橡胶材料制成，所述第一防水层和第二防水层的表面均涂布有具有憎水性能的环氧树脂。
优选的，所述编织屏蔽层是由镀锡铜丝加芳纶纱编织而成。
本发明提出的一种交联聚乙烯绝缘聚烯烃护套无卤低烟阻燃电力电缆，有益效果在于：本发明通过设置加强条、加强层和加强钢丝，可以有效的提高本发明自身的强度，通过设置由防水橡胶材料制成由第一防水层和第二防水层，以及在第一防水层和第二防水层的表面涂布具有憎水性能的环氧树脂，可以对本发明进行有效降温延长使用寿命的同时可以有效地防止在进行水冷工作时出现漏水的现象，同时与内部均设有空腔的支撑四棱台相配合，可以防止本发明在受到挤压时堵塞冷却水的流通，通过设置由无卤聚烯烃材料制成的隔热层，使本发明的隔热、抗震缓冲和耐火性能得到提升，通过在无卤低烟内护套层的表面设有多个齿槽，使无卤低烟内护套层和隔热层之间形成多个空腔，进一步降低了热量的导入，本发明通过采用多种无卤低烟阻燃材料，在火灾事故发生时避免了因燃烧产生大量的烟雾以及有毒有害气体，提高了安全性。
