Innovation on the move at SADTEM!

SADTEM is moving away from its traditional business as a manufacturer of inductive instrument transformers, by launching its first Capacitive Voltage Divider.

OVS-52 is designed for voltage detection on catenaries 25kV or 27.5kV.

With a simple and proven design, based on our long experience of manufacturing quality, derived from the silicone insulators of traditional Voltage Transformers, it is perfectly adapted to severely polluted environments and is insensitive to strong temperature variations.

Qualification of the new product Y12G-C1!

SADTEM, and its partner #SECURELECSOCEM, are pleased to announce the qualification of their new Y12G-C1 product integrated into a TRI Y12GC1 assembly, developed for their client EDF/ENEDIS.

This new national market, won by two, clearly shows the competitive interest of bringing together companies from the same ecosystem at the regional level.

This set is intended for the reliability of the protection circuits of HTB/MV substations and is therefore equipped with 3 24kV Voltage Transformers (one per phase).
