Sediver composite insulators for railway applications


Sediver is a key partner in all insulation applications with more than 2 million insulators operating today on numerous Railway networks with different applications and voltages such as

  • 15 kV and 25 kV on AC systems and
  • from 0.75 kV to 3 kV on DC systems

Since 1955, Sediver has been a supplier of catenary insulators to many railway companies. As a proof of good performance and reliable partnership, Sediver has been selected and qualified by S.N.C.F (France) as a supplier for the TGV – the French High Speed railway - which imposes very stringent safety criteria and reliability requirements.

Sediver product range

Sediver composite insulators consist of a fiberglass rod protected by EPDM or Silicone rubber and assembled with metal fittings.
Through a highly developed design and carefully selected materials, Sediver insulators assure the safest usage which in turn reduces the cost of inspection and maintenance.

Sediver studies and adapts its insulators and end fittings to the specifications of every railway company and project:


- Feeder insulators

- Top and strut tube insulators

Sediver composite insulators can be installed safely in tunnels since both the EPDM and Silicone materials used by Sediver have self-extinguishing properties: when a flame is applied, they burn without producing any toxic fumes and extinguish as soon as the flame is removed.
