技术领域
本发明属于电缆材料技术领域，具体地说，尤其涉及一种纳米复合乙丙橡胶电缆。
背景技术
电力电缆一般敷设在地表以下，常用作电厂、变电所、厂矿企业的动力引入或引出线。电力电缆与架空线相比，因其铺设在地表以下，所以受气候的影响较小，安全可靠，隐蔽耐用，但是材料成本、敷设费用、维护费用比较高，而且检修和故障排查也比较困难。传统电缆的外绝缘材料主要是由乙丙橡胶或聚乙烯等聚烯烃构成，因而普遍存在着易燃烧的缺陷；现有的阻燃型电缆，普遍存在柔韧性大幅度下降缺陷，其不能适用于移动频繁的场所。
发明内容
本发明的目的在于克服上述缺陷，提供一种纳米复合乙丙橡胶电缆，其原料低廉、配伍合理，绝缘性能好，在具备良好的阻燃性的基础上，保证了电缆的韧性。
