SIMABUS connectors case study

Case Study

Powering Tomorrow's Travel

New innovative SIMABUS connectors were the key to a challenge faced on a new high-speed rail line in France.

Extraordinary Customer Experience

TE's teams worked proactively with a customer to meet a double challenge. With the expertise of TE's engineers, an adaptive solution in the new railway traction substations was provided and products were installed only 3 weeks after engineer's approval.

The Challenge

The South Europe Atlantic (S.E.A.) project, a new high speed rail line in France, will shorten the trip from Paris to Bordeaux to just over 2 hours.

The French utility required all connectors to be designed as per its requirements. For the new specific layout design of the railway traction substations, it required adaptive solutions to the infrastructures such as busbar supported horizontally by post insulators, because the conventional connector solution did not fit to this specific configuration.

The Solution

With innovative new SIMABUS connectors, TE's team took up the double challenge:

  • delivering an alternative connectivity solution
  • within the initial timeframe


These connectors allow a fixed or sliding function to the connected tube. They can be installed independently in a vertical or horizontal position at site without adaptation of the supporting structure. Their modularity also allows TE to manage available inventory on standard components. Consequently the customer’s connector becomes fast to produce by assembling standard components.

The Outcome

TE brought more than just connectors. Our experts avoided the commissioning delay of that substation which would have led to huge financial penalties.

Reworking established technical specifications, optimizing products to save costs, designing products to fit customer applications and providing technical expertise in the field, are daily business for TE’s engineering teams.
