Description

一种高压电缆的缓冲层绕包及金属套焊接联动生产线 技术领域
本发明涉及高压电缆制备技术领域,特别是涉及一种高压电缆的缓冲层绕包及金属套焊接联动生产线。
背景技术
高压电缆的绝缘线芯外依次包覆有缓冲层和金属套。其中,绝缘线芯包括三层,从内往外分别为内半导电屏蔽层、绝缘层和外半导电屏蔽层。金属套的作用一是防止XLPE绝缘接触到水分产生水树枝,是电缆的径向防水层,二是能承受零序短路电流,热稳定性好。缓冲层由半导电性的阻水膨胀带绕包而成,其作用一方面是使绝缘线芯的外半导电屏蔽层与金属套保持电气上的良好接触,另一方面还有具备纵向防水性能。
目前,随着我国高压电缆生产技术的大力发展,110kV、220kV高压电联产量逐年增长。随着高压电缆生产和应用越来越多,发现电缆的故障主要集中在缓冲层的烧蚀,而造成烧蚀的主要原因是其缓冲层材料本身的性质决定的。通过上述电缆结构及材料分析可知,电缆缓冲层的材质为半导电阻水膨胀带,其具有极易吸潮的特点,若在生产的过程中发生吸潮现象,则生产后的电缆在投入使用后,在运行几年后,其绝缘屏蔽层及缓冲层会发生烧蚀,导致电缆击穿的可能性增大。故在电缆生产过程中,缓冲层的防潮处理非常关键,直接影响到电缆未来的运行稳定性。在生产过程中对缓冲层进行防潮处理目前仍处于空白期。
发明内容
