Micro-duct air-blowing cable deployment technique was first invented by NKF Cable Company of the Netherlands, which is suitable for all kinds of network construction. In this technique, HDPE sub-ducts are blown into the parent duct made of HDPE or PVC deployed before; then micro cables of either all dielectric stranded loose tube structure or central stainless steel loose tube structure are blown into the above sub-ducts by compressed air step by step. Thus, it can overcome the disadvantages of current deployment method for duct cables and greatly increase the efficiency of duct utilization. Meanwhile, it is easy for network expansion and cable branching at anytime.
