本文提供了以真空浸渍压力成型新工艺在高电性能绝缘管制造中应用的范例。将此制品与用传统卷压工艺制得的绝缘管的致密性进行分析对比后表明,管材致密性提高后介电性能明显提高,并通过实验阐述了应用真空浸渍压力成型工艺提高绝 This article provides examples of new applications of vacuum impregnation pressure molding in the manufacture of high-performance insulating tubes. Comparing the compactness of this product with the insulation tube made by the traditional crimping process, it shows that the dielectric property of the product is obviously improved after the pipe density is increased. And the application of vacuum impregnation pressure forming process to improve
