Added value

SuperGrid Institute’s material platform has developed a strong knowledge in dielectric materials through a close partnership with renowned laboratories such as IMP and G2ELab. The core competency of this platform lies in material ageing under thermo-electric stress. Each step, from material preparation, physicochemical and electrical characterisation, ageing test design and ageing testing is performed in the platform and benefits from the support of partners to offer a service that focuses on the specific application of the material in the high voltage system.
