Abstract

一种铝合金芯铝绞线接续管,涉及一种电力设备。该接续管两侧出口端为带有锥度的拔梢。本实用新型结构简单,成本低廉,方便工程应用。该接续管两侧出口端为带有锥度的拔梢,提高了导线压接强度保留率,增大了拉断力,压接拉力试验值大于设计破坏力的95%,能够安全可靠地完成导线的接续。

Description

铝合金芯铝绞线接续管
技术领域
本实用新型涉及一种电力设备。
背景技术
铝合金芯铝绞线作为一种新型节能导线,被大力提倡推广应用。但是,目前该类型导线在接续时没有相配套的接续管,如果套用其它类型导线的接续管,如常规的钢芯铝绞线接续管拔梢长度相对较短,并且整体为圆柱形结构,由于导线结构型式的不同,很难完全匹配,即使基本匹配,压接后的拉断力也达不到使用要求,直接影响架线的安全可靠性,从而为铝合金芯铝绞线的导线接续带来困难。
发明内容
本实用新型的目的是提供一种铝合金芯铝绞线接续管,以解决目前该类型导线没有配套接续管,无法可靠完成导线接续的问题。
本实用新型主要由接续管本体组成,解决其技术问题所采用的技术方案是该接续管两侧出口端为带有锥度的拔梢,拔梢长度为导线外径的3倍,拔稍的锥度为1:7至1:8。
采用本实用新型的积极效果是结构简单,成本低廉,方便工程应用。该接续管两侧出口端为带有锥度的拔梢,提高了导线压接强度保留率,增大了拉断力,压接拉力试验值大于设计破坏力的95%,能够安全可靠地完成导线的接续。
附图说明
下面结合附图和实施例对本实用新型进一步说明:
图1是本实用新型结构示意图;
图中1拔梢、2接续管本体。
具体实施方式
如图所示:该接续管本体2两侧出口端为带有锥度的拔梢1,拔梢1长度为导线外径的3倍。其中拔稍1的锥度为1:7到1:8。接续管本体采用纯铝材质。
