一种高压电缆的缓冲层绕包与金属套挤包联动生产线 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与金属套挤包联动生产线。
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，高压电缆在实际使用过程中，容易发生绝缘屏蔽表面、缓冲层烧蚀，导致电缆被击穿。从高压电缆本体事故分析看来，电缆缓冲层的烧蚀问题尤为严重。这是因为阻水膨胀带极易吸潮，吸潮后的带材生产出来的成品电缆，在投入使用后，前些年可能不会存在太大问题，但在运行几年、十几年后极有可能出现绝缘屏蔽表面、缓冲层烧蚀，进而增大了电缆击穿的可能性。因此，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。
