Stratiforme Industries improved the inner dielectric and mechanical properties of the composite material to bring it to a level never reached before with an SMC component, through specific testing, coating and a clever universal design. The SMC part was thoroughly tested in collaboration with SNCF (electrical) and ARMINES (mechanical) during 10 years in order to prove its relevance for use as a stand-alone insulator on multi-voltage catenary systems (750 to 25 kV).
The part design evolved through this 10-year project, starting from RTM and infusion parts to a high-productivity SMC process for the final version, benefiting from a universal design (the SMC part is common to all the ACCUM versions).
Different environmental protection coatings were developed and tested on tracks with the support of the CEF testing centre. More than 100 prototypes are currently on test tracks in France.
> Dramatically reduced installation and maintenance times
> Can be used with 750 to 25 kV lines, on all standard and specific points
> Increases the system reliability by eliminating glass and ceramic insulators
> Pre-assembled by Stratiforme Industries and delivered ready to mount
> Number of components dropped down to 10+ parts versus 100+
