Abstract

本实用新型公开了一种绝缘导线，包括通电导线和套于其外的绝缘层，所述绝缘层外包覆有耐火层。所述的耐火层为石棉布层。本实用新型的优点在于在导线的绝缘层外再包覆有耐火层，一是可以提高导线的耐高温性能，延缓绝缘层的老化周期，保证导线在恶劣工况下的使用安全；二是当外界着火时，耐火层能延缓导线的正常工作时间，给有效救助提供时间。由于石棉的造价低廉，耐火层可以为石棉布层，当然也可以用其他耐火材料制成耐火外层，同样也能达到该种效果。

Description

绝缘导线
技术领域
本实用新型涉及电线，尤其是涉及一种可以耐高温的绝缘导线。
背景技术
电线老化或气温过高导致电线短路会引起火灾，由于其他原因起火后将电线绝缘层烧坏引起线路故障，会加大火灾灾情，如何能延长电线使用时间或在起火后提供较长的救助时间，以最大限定减轻损失，常规的绝缘电线显然达不到该种要求。
实用新型内容
本实用新型的目的在于提供一种可耐高温更安全的绝缘导线。
为实现上述目的，本实用新型可采取下述技术方案：
本实用新型所述的绝缘导线，包括通电导线和套于其外的绝缘层，所述绝缘层外包覆有耐火层。
所述的耐火层为石棉布层。
本实用新型的优点在于在导线的绝缘层外再包覆有耐火层，一是可以提高导线的耐高温性能，延缓绝缘层的老化周期，保证导线在恶劣工况下的使用安全；二是当外界着火时，耐火层能延缓导线的正常工作时间，给有效救助提供时间。由于石棉的造价低廉，耐火层可以为石棉布层，当然也可以用其他耐火材料制成耐火外层，同样也能达到该种效果。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
如图所示，本实用新型所述的绝缘导线，包括通电导线1和套于其外的绝缘层2，所述绝缘层2外包覆有耐火层3；考虑到成本费用，所述的耐火层3可以为石棉布层，当然也可以由其他耐火材料制成的耐火外层，同样也能起到耐高温的安全效果。

Claims (2)

1、一种绝缘导线，包括通电导线(1)和套于其外的绝缘层(2)，其特征在于：所述绝缘层(2)外包覆有耐火层(3)。
2、根据权利要求1所述的绝缘导线，其特征在于：所述的耐火层(3)为石棉布层。
