Fast cable installation into ducting is key for cost effective, low disruption network build. Cable blowing is the method of choice for longer routes whereby cables are propulsed into the ducting using compressed air.

The blowing distance achieved is directly related to a number of factors including: cable to duct area fill ratio (we recommend 50 to 60% ideally but no more than 70%); weight of cable; pressure used, route difficulty (bends and gradients) and last but not least the Coefficient of Friction (CoF) from the microduct inner lining.

The contribution of the microduct inner lining to achieving speed of installation and longer blowing distances should not be underestimated. A quality lining should have the right combination of low CoF and low static for optimum results and for that reason, not all linings are created equal.
