Pyro MI cables serve safety applications in new landmark London development
Many tens of kilometres of Pyrotenax mineral-insulated cables serve life-safety and fire-fighting rated applications at 1fifty Cheapside in London.
Pyrotenax mineral-insulated cables have been installed for fire-rated applications in the 19 000 m2 office development at 1fifty Cheapside near St Paul’s Cathedral in London. Specified by Hilson Moran and installed by Haden Young as the backbone system for landlord services in the shell and core. These cables are used in circuits for life-safety and fire-fighting rated applications as defined in BS 7346-6 specification for cable systems. At 1fifty Cheapside, a range of heavy-duty Pyro MI cables up to 1H185 has been used for the fire-rated power applications. They include sub-mains for life safety systems, fire-fighting lifts, fire interface to mechanical equipment and panels, extract fans, motorised smoke dampers, sprinkler pumps and fire-alarm panel supplies. For the fire-rated communication applications, including voice alarms and all fire telephones, over 30 km of light-duty Pyro MI cable has been installed. 1Fifty Cheapside is a development by St Martins Proportion and due for completion in summer 2008. It has eight floors of commercial office space above retails units on the ground and lower-ground levels. The building has achieved an ‘excellent’ BREEAM rating.
