Pyro MI Cable Fixings

Pyro cable tray with double run

To secure Pyro MI Cable, far fewer fixings are required in comparison with other cable types. By using Pyrotenax recommended fixing distances, savings of up to 40% can be achieved on fixing costs compared to conventional fixing distances. Whether fixed on the surface, on a cable tray, behind plaster, in a roof space or suspended ceiling, Pyro MI cable measures up to a real installation cost advantage. The fixing distances shown in the table below represent a saving of up to 40% in comparison with traditional methods of installation practice, where pliable cables are fixed at an average of 225mm (9”) intervals compared to the Pyrotenax recommendation of 350mm (14”) centre.

Where considerable lengths of cable are involved, the savings can be very substantial—especially when matched against the cost of the cable itself.
