For our Fabric Innerduct’s pulling tape, it have 370kg and 500kg, we advice to use 500kg pulling tape.
Cause the tension of optical cable always set as 1500N or 150kg, but while the pulling tape traction the optical cable, it will have friction between optical cable and pipeline opening. According to our experience, the force of workers traction pulling tape on road is about 10 times compare with underground pipeline optical cable tesion, and the force will gain according to undergound deepth.
For example, if undergound pipeline optical cable tesion is 25kg, then the force of workers traction pulling tape on road is about 250kg.
