This system has been studied, projected and realized by Cembre in 1988 after a deep analysis of existing electrical connection systems and their performances. The aim of the Cembre system is to provide a general and substancial improvement on the most important caractheristics of a contact between the rail and the electric cables like:

• extremely low resistance (in terms of micro-ohms);
• easy installation procedures and not depending on operator skilness;
• short installation time (less than one minute for each operation);
• possibility of disconnection / connection of attached cables.
• cold extruded (requires no heating to the rail).

After extensive tests, either in laboratory or in the field, the system has been recognized as totally reliable and perfectly matching the above listed requirements.
