ITER 环形场 (TF) 线圈的设计需要一个绝缘系统，该系统能够适应为建造这些设备而计划的超大规模真空浸渍工艺，并且在辐射暴露后提供可靠的机电性能。为了满足这一需求，CTD 开发了一种环氧/氰酸酯树脂系统，命名为 CTD-425。该材料满足 TF 线圈的加工要求，导体组件的循环机械测试已证明其在 60,000 次机械循环后的机电强度。此外，该产品最近还通过了ITER国际组织协调的辐射暴露测试，现已有资格用于构建TF线圈。本文总结了该绝缘材料的性能特征和鉴定测试结果。
The design of the ITER Toroidal Field (TF) coils requires an insulation system that is amenable to the very large scale vacuum impregnation processes planned for the construction of these devices, and that will provide reliable electro-mechanical performance after radiation exposure. To address this need, CTD has developed an epoxy/cyanate ester resin system designated CTD-425. This material meets the processing requirements for use in the TF coils, and cyclic mechanical testing of conductor assemblies has demonstrated its electro-mechanical strength after 60,000 mechanical cycles. In addition, this product recently passed radiation exposure tests coordinated by the ITER International Organization and is now qualified for use in constructing the TF coils. This paper summarizes the performance characterization and qualification test results for this insulation.
