Description

升降灯用螺旋电缆
技术领域
本实用新型涉及电缆制造领域,特别是一种升降灯用螺旋电缆。
背景技术
螺旋电缆是一种利用线缆螺旋的可伸缩性来工作的设备连接线,被广泛的应用于各种移动设备和升降设备中。
螺旋电缆在实际应用中,如果长期处于超过其弹性变形极限的状态,会导致塑性变形,失去原有的弹性,造成线缆的机械疲劳现象。目前市场的螺旋电缆的弯曲性能较差,连续使用时恢复效果越来越差,导致最终无法恢复到初始状态,容易出现电缆卡断现象,影响设备的正常使用,也增加了维护费用。
发明内容
本实用新型目的在于提供一种柔韧性、弯曲性能优秀的升降灯用螺旋电缆。
本实用新型包括三股绝缘导体,在所述绞合的绝缘导体外设置TPU外护套层;所述绝缘导体包括无氧铜丝导体,在所述无氧铜丝导体外包裹PVC绝缘层。
本实用新型采用0.10mm、0.08mm以下较细铜丝作为导体,使电缆的柔韧性、弯曲性能优秀,克服了电缆在较长时间使用的情况下不能恢复初始状态的问题,避免了电缆卡短现象,降低了维护费用。本实用新型被广泛应用于应急抢修移动照明灯具传输电能、连接。
附图说明
图1为本实用新型结构示意图。
具体实施方式
如图1所示,本实用新型设有三股绝缘导体,在所述绞合的绝缘导体外设置TPU外护套层3;所述绝缘导体包括无氧铜丝导体1,在所述无氧铜丝导体1外包裹PVC绝缘层2。
