产品介绍

冷缩电缆终端头是利用弹性体材料(常用的有硅橡胶和乙丙橡胶)在工厂内注射硫化成型,再经扩径、衬以塑料螺旋支撑物构成各种电缆附件的部件。现场安装时,将这些预扩张件套在经过处理后的电缆末端或接头处,抽出内部支撑的塑料螺旋条(支撑物),压紧在电缆绝缘上而构成的电缆附件。因为它是在常温下靠弹性回缩力,而不是像热收缩电缆附件要用火加热收缩,故俗称冷收缩电缆附件。早期的冷收缩电缆终端头只是附加绝缘采用硅橡胶冷缩部件,电场处理仍采用应力锥型式或应力带绕包式。产品属性现在普遍都采用冷收缩应力控制管,电压等级从1kv到35kv。冷缩电缆终端头,1kv级采用冷收缩绝缘管作增强绝缘,1kv级采用带内外半导电屏蔽层的接头冷收缩绝缘件。四芯电缆终端分叉处采用冷收缩分支套。注意事项必须指出的是,在安装到电缆上之前,预制式电缆附件的部件是没有张力的,而冷缩电缆终端头是处于高张力状态下,因此必须保证在贮存期内,冷收缩式部件不应有明显的永久变形或弹性应力松弛,否则安装在电缆上以后不能保证有足够的弹性压紧力,从而不能保证良好的界面特性。其他说明冷缩电缆终端头具有体积小、操作方便、迅速、无需专用工具、适用范围宽和产品规格少等优点。与热收缩式电缆附件相比,不需用火加热,且在安装以后挪动或弯曲不会像热收缩式电缆附件那样出现附件内部层间脱开的危险(因为冷缩电缆终端头靠弹性压紧力)。与预制式电缆附件相比,虽然都是靠弹性压紧力来保证内部界面特性,但是它不像预制式电缆附件那样与电缆截面一一对应,规格多。

低压电力电缆冷缩附件,俗称冷缩电缆终附件,亦称1KV冷缩电缆头。低压冷缩电缆头分为单芯、三芯、四芯、五芯,分别适用于电缆截面积介于10-400mm之间,是一种采用抗老化性强的高弹性进口硅橡胶原料制作的新型电缆附件,产品具有抗漏电痕、抗电蚀;耐高低温、耐恶劣环境、高弹性等物理特性。其绝缘电气性能优越,密封性可靠,收缩力恒定,不受电缆弯曲造成绝缘死角。产品安装方便、快捷,便于电力抢修。产品现场安装时不借用任何明火或专业工具,克服了热缩型在施工时需要热源的缺点,便于野外使用,并提高了产品的安全性和可靠性。产品安装后对电缆保持径向压力,防潮防湿效果好,并使用了密封胶、防水胶带等进一步提高了密封效果。

安装工艺指导

安装时,请将预扩张件套在经过处理后的电缆末端或接头处,抽出内部支撑的塑料螺旋条(支撑物),压紧在电缆绝缘上而构成电缆附件。
