Founded in 1921, our name was ELECTRO-PORCELAINE and even at that time we were manufacturer of porcelain insulators


history4 history4


history2We took the name of CERALEP in 1923 when MERLIN GERIN purchased us.

Some time around the 60s CERALEP specialized in manufacturing porcelain insulators for high and ultra high voltage, specialty we still have today.

In 1972 ALSTOM ATLANTIQUE invested in CERALEP and at the same time we merged our both production plants (Andancette – Drôme in France) and Bazet (Hautes Pyrénées in France) in one site where we are today.

In 1989 KERAMIK HOLDING AG LAUFEN (Switzerland) acquired 80 % of CERALEP’s capital.

In 1993, CERALEP becomes CERAM when this Swedish group purchases our company.



CERALEP SN is now completely independent as company belongs to their employees. The 62 employees are all shareholders of CERALEP SN and have a total autonomy for decisions and investment strategy.
