Bending radius during installation should always bigger than the overall diameter the cable (unless otherwise specified the cable manufacturer).Guidelines for the installation unilan® products
Communication technology
Cable pulling
• Always pull cables directly from the drum box. Open wires tied with insulating tape between moving equipment and cable sheath (Doesn’t apply cables)
Bending radius
• According EN50173. Use all wires for retracting. For cables with pairs metal foil (S/FTP, PiMF) the foil screen should maintained close possible the point termination. two different bending radii are listed, i. That avoids possible EMC influence.
Terminating the patch panel
• Always follow the connecting hardware manuals. Never expose Uninet data cables direct heat sources. Therefore please look «regulations, standards and guidelines».: bend radius with the higher value during installation bend radius with the lower value after installation
Copper screened
Pressure data cables
Copper unscreened
• Avoid any pressure data cables! Crushing that effects the wires can have negative effect the transmission characteristics the cable. Never pull the cables over the flange the reel (risk twisting). Avoid storing ‘reserve loops’ the patch panel. Rewind unused cable and fix the end firmly. Never use hot air gun gas burner, e.g.e. When using reels always use suitable equipment that will ensure free rotation the reel. Always check the data sheets for exact specifications. The most frequent reasons crushing are improperly fixed cables, crossing cables and mechanical stress cables. For cables with intermediate sheath the intermediate sheath and associated foil screen should maintained close possible the point termination. when using heat shrinking tubing.

Cable laying
Systems
• Lay data cables separate channels from power cable and always cross 90° using bridge.
Heat influence
Fibre optic
• Foamed wires are sensitive direct heat influence
