Tecbor® Boards - Cable Tray

Protecting the wiring adequately will be crucial when electrical supply systems must be kept in optimal running conditions during fires. In tunnels, heavy traffic buildings or high-rises, it is of paramount importance to perform orderly evacuations while basic systems keep running.

Tecbor® B 40 mm has been tested covering a cable tray from different sections and evaluated according to UNE EN 1363-1 general requirements, following the heating curve defined by UL 1709 standard. Electric conductivity, short-circuit between cables and earth fault have been also added.

Facilities may be accessed through inspection hatches. Likewise, Tecsel® Grids allowing for ventilation and sealing the hole in case of fire have been tested (For additional information, please contact our Sales Department.).
