ITER磁体系统包括18个校正线圈（CC），由NbTi导管内电缆10ka导体制成，绕成多个煎饼。匝绝缘和地绝缘采用玻璃带/聚酰亚胺交织多层复合材料进行电绝缘，该复合材料应浸渍环氧树脂。在这些线圈的制造过程中，仍有一些技术问题需要解决。其中一个问题是绝缘系统的浸渍和固化，要达到良好的机械性能和足够的高压绝缘（5kv）。采用真空加压浸渍法（VPI）对绝缘系统进行了制造试验，这是一种有效的方法，可以去除绝缘系统中的干点和过富树脂等缺陷。为了模拟和优化可行的VPI工艺，制作了两个长度为1000 mm的VPI试样。本文详细介绍了混凝土的绝缘材料和绝缘结构的VPI工艺，并给出了相关的机械和电气试验结果。在室温和液氮温度（77 K）下对其力学性能进行了测试，包括抗拉强度、层间剪切和压缩剪切（45）。此外，还对试验样品上匝绝缘和地绝缘的介电强度进行了测试。根据设计要求对试验结果进行了讨论。
ITER Magnet System includes 18 Correction Coils (CC), made with NbTi cable-in-conduit 10 kA conductor, wound into multiple pancakes. The turn and ground insulation were electrically insulated with a glass tape/polyimide interleaved multilayer composite, which should be impregnated with epoxy resin. Some technical issues remaining have to be addressed in the manufacturing process of these coils. One of the issues is the impregnation and curing of the insulation system, which should achieve good mechanical properties and sufficient high voltage insulation (5 kV). The authors performed manufacturing trials of the insulation system using the vacuum pressure impregnation (VPI) method, which is an effective process to remove defects such as dry spots and over rich resins in the insulation system. In order to simulate and optimize the feasible VPI process, two VPI test samples with the length of 1000 mm have been fabricated. In this paper, we introduce the detailed VPI process including the insulation materials and insulation structures for CC and present the results of the related mechanical and electrical tests performed. The mechanical properties, including tensile strength, inter-laminar shear as well as compressive shear (45 ) were evaluated at room temperature and liquid nitrogen temperature (77 K). In addition, the dielectric strength of the turn insulation and the ground insulation on the test samples were also examined. The results of the tests were discussed versus the design requirements.
