If a large coil (equivalent to 40 cm) is used as a mandrel

If a large coil (equivalent to 40 cm) is used as a mandrel to pull the cable, the jacket of the cables of tight structure can be pulled in the wiring facilities in the internal plant. Wrap the cord around the coil 5 times and hold it gently when pulling.

It must not exceed the maximum value of the tensile tension. Manufacturers and suppliers of conduits, corrugated pipes and cable lubricants should be consulted for guidelines on stress values ??and lubricant use.

When pulling long cables in corrugated conduits or subducts (up to 3 miles or 5 kilometers on the outer floor or hundreds of meters on internal plant wiring), the appropriate cable lubricant should be used, but make sure it is compatible with the jacket of the cable. If possible, use a cable handle with tension control and / or an individual hitch swivel. In long-term cable runs on an external floor (more than 2.5 miles or 4 kilometers), the cable must be pulled to both ends or an automatic cable puller must be used at one or more intermediate points for a continuous run.   

When resting the fiber loops on a surface while making a roll, it must be supported in the form of an "8 figure" to avoid twisting the cable.
