Sediver product range

With over 60 years of specialized experience in insulators, complemented by laboratory tests, Sediver can offer the safest and most reliable toughened glass insulators for railways which can be depended upon for their mechanical and electrical strength throughout their life.

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


- Feeder insulators

- Top tube insulators

Sediver glass strut and top insulators
   

- Strut tube insulators

Sediver glass railway strut and top insulators

The top and strut insulators are of a rigid construction, comprising three or four toughened glass shells connected by intermediate metal fittings. The toughened glass shells and metal fittings are assembled together using alumina cement, to give a bond which is stronger than the components themselves.
