FIRECEL MI are intended to be installed in critical safety circuits which are used to operate under fire conditions in severe applications where the mechanical cables performances are primarily required.
Production process foresee many steps of diameter reduction (both drawings and rollings) separated by high temperature annealing.
Strong compression of MgO powder (density about 2 g/cm3) allows very high values of insulation resistance (also if burned, 180° bent or flattened) and thermal conductivity. Therefore current ratings are higher than soft skin cables, especially at high temperature.
Cable Uses
- Drilling & Tunnelling
- Emergency Lighting
- Fire Alarms
- Fire Detection
- Hazardous Areas
- Historical Buildings
- Industrial Plants
- Harsh Environments
- Mining
Fire Standards
Our ’Enhanced’ MI cables are manufactured in the European Union in accordance with British Standards BS EN 60702 –1: 2002 and EN 50200:2013 Clause 26.2.
Cable construction
| Conductor | ETP solid (not stranded) copper cores, from 1 to 400 mm2, melting point 1082°C |
| Insulation | Magnesium Oxide (MgO) as electrical insulation, high performance at high temperature (melting point 2600°C) |
| Metallic Outer Sheath | High quality DHP copper sheath, manufactured starting from tubes extruded and drawn only (not welded), melting point 1082°C |
| Outer Sheath | LSZH additional outer covering. Such flame retardant polyolefin is characterised by high performance in corrosion resistance and low smoke emission |
