Ce-Tek manufactures two series of fire rated junction boxes:
-CEP which is made from glass reinforced polyester with thick walls.
-CEX which is made from 316L stainless steel.
These two ranges have been passed for use to IEC331 at 750°C for 3 hours
and to BS6387 CWZ at 950°C for 3 hours (C is resistance to fire alone, W is resistance to fire with water and Z is resistance to fire and mechanical shock).
Both series comply with BS8519-2010 for life safety.
Ce-Tek products are to be found in the Channel Tunnel, the Channel Tunnel Rail Link project, London Underground, Thames service tunnels, M25 Motorway tunnels and canal tunnels for Network Rail.
