News International-French

13 Mar 2019

ACCUM is a universal composite catenary cantilever validated from 750V to 25kV and suitable for all standard and specific railtrack profiles, designed for easy supply, installation and maintenance.

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.

Key Benefits:
> 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+

This innovation has been selected as a finalist for the JEC Innovation Awards 2019 in the Industry & Equipment category.

The JEC Innovation Awards - organized by the JEC Group - are recognized as the industry’s most prestigious awards that identify, promote and reward the most innovative composite projects worldwide.

The award winners will be announced during JEC World 2019 on 13 March at 4.30pm. Stratiforme Industries will showcase their innovation at JEC World 2019 at Booth N32, Pavilion 6. Their associated partners are Armines Douai, CEF Centre d'essais ferroviaires, SNCF Réseau.
