About the TeaM Cables project
- Cables, especially their insulation and jacket materials made of polymers, are vulnerable to ageing degradation during normal operation and accidents and means must be established to ensure that cable ageing does not lead to unsafe operation.
- Latest developments in polymer ageing research have revealed limits in current methods for estimating the lifetime of polymer materials. These are related to the lack of representativeness of accelerated ageing and the lack of consideration of the polymer composition (e.g. fillers, additives, antioxidants) in ageing models.
TeaM Cables will develop a novel multiscale approach for more precise estimation of the cable lifetime. The project will analyse the effects of irradiation and temperatures on cables from micro- to macroscale level, in order to develop multiscale models of ageing. Ageing in normal operation conditions and accidental conditions will be addressed.
The unique multi-scale and kinetic models produced by the project will be integrated into an open access tool – the TeaM Cables tool – which will be built on the merger of a currently used European cable management tool with a cable ageing modelling tool. In parallel, criteria and protocols for on-site use of non-destructive testing techniques will be proposed.
