为了实现上述目的，本发明是通过以下技术方案实现的：一种稀土铝合金低压电缆，它包括缆芯以及缆芯外部自内向外包覆的聚酯包带层、内衬层、金属屏蔽层以及交联聚乙烯绝缘护套；所述缆芯由线芯围绕加强芯均匀挤包而成；所述线芯包括稀土铝合金导体以及稀土铝合金导体外绝缘层；所述缆芯与聚酯包带层之间还设有泄流线；所述缆芯、聚酯包带层以及泄流线之间的间隙部分设有填充层；所述聚酯包带层与金属屏蔽层之间均匀设置四组镀银抗拉丝；所述镀银抗拉丝贯穿内衬层。
进一步的，所述内衬层为PVC再生层。
再进一步的，所述金属屏蔽层为多条网状钢丝编织而成。
更进一步的，所述镀银抗拉丝横截之间为0.5-0.65mm。
本发明的有益效果是：本发明结构简单、设计合理、防火性能好、安全性高、电流损失小、防腐屏蔽性好、机械性能佳。
