Therefore please look «regulations, standards and guidelines».
. The most frequent reasons crushing are improperly fixed cables, crossing cables and mechanical stress cables. Never pull the cables over the flange the reel (risk twisting).e.

Pressure data cables
Copper unscreened
• Avoid any pressure data cables! Crushing that effects the wires can have negative effect the transmission characteristics the cable. That avoids possible EMC influence. For cables with intermediate sheath the intermediate sheath and associated foil screen should maintained close possible the point termination. Always check the data sheets for exact specifications. Rewind unused cable and fix the end firmly.Guidelines for the installation unilan® products
Communication technology
Cable pulling
• Always pull cables directly from the drum box. two different bending radii are listed, i.
Terminating the patch panel
• Always follow the connecting hardware manuals.
Heat influence
Fibre optic
• Foamed wires are sensitive direct heat influence. Avoid storing ‘reserve loops’ the patch panel. when using heat shrinking tubing. Bending radius during installation should always bigger than the overall diameter the cable (unless otherwise specified the cable manufacturer). Open wires tied with insulating tape between moving equipment and cable sheath (Doesn’t apply cables)
Bending radius
• According EN50173. Never expose Uninet data cables direct heat sources.
Cable laying
Systems
• Lay data cables separate channels from power cable and always cross 90° using bridge. When using reels always use suitable equipment that will ensure free rotation the reel.g. Never use hot air gun gas burner, e. For cables with pairs metal foil (S/FTP, PiMF) the foil screen should maintained close possible the point termination. Use all wires for retracting
