Tecbor\u00ae Boards - EI-120 Cable Tray Protection<\/h1>
<\/div><\/div>[vc_row_inner equal_height=”yes” content_placement=”middle”][vc_column_inner width=”2\/3″][vc_column_text]<\/p>\n
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
\nbasic systems keep running.
\nTecbor\u00ae\u00a0 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.
\nElectric conductivity, short-circuit between cables and earth fault have been also added. Facilities may be accessed through inspection hatches. Likewise, Tecsel\u00ae Grids allowing for ventilation and sealing the hole in case of fire have been tested (For additional information, please contact our Sales Department<\/a>.).<\/p>\n

Description of assenbly<\/h2><\/div>[vc_column_text]The tray is protected by a layer of Tecbor\u00ae 40 mm boards set together with 5.2×80 mm self-tapping screws. At duct section joints, place a 200 mm wide board strip of 20 mm Tecbor\u00ae B and fix it to the metal tray and to each other using 3.5×45 mm screws.
\nThe duct is anchored to the slabs with a 12 mm rod and supported by 50x50x5 mm angle sections.
\nBoard joints and screw heads should be covered with Tecbor\u00ae joint paste ready to use.
\nPenetrations seals:<\/strong>
\nFill the hole between the duct and the structural work with 50 mm and 145 kg\/m3 rock wool and paint both sides with Tecbor\u00ae joint paste<\/a> 1 ready to use.[\/vc_column_text][vc_single_image image=”28551″ img_size=”800×400″ alignment=”center” onclick=”link_image”][\/vc_column_inner][\/vc_row_inner][vc_empty_space height=”30px”][\/vc_column][\/vc_row][vc_row][vc_column]
