The cables are intended for the distribution of electricity in fixed installations
The cables are intended for laying in tubes and pipes, on cable trays and cannot be installed directly in the ground or in water.
When burning, the cables do not release toxic and corrosive gases and have low smoke emission.
The cables are not intended to work in special environments (explosive or in the CNE side of the reactor).
