DB Assemblies – Aluminium
Double Sheath
Direct Bury (DB) microduct assemblies with MiniGlide™ & MicroGlide™ are robust and designed to be buried directly in the ground. The assemblies include a 150µ aluminium layer which acts as a moisture barrier.
Made from high-quality prime PE materials, all our microducts feature our proven Low Friction permanent inner coating to deliver class-leading blowing performance. Available with ribbed or smooth inner bore according to your preference.
What is Low Friction coating?
A solid layer of lubricant is evenly distributed on the inner wall by coextrusion as part of the manufacturing process, providing a permanent low friction and low static surface which lasts for the life of the duct.
Low friction values allow quicker installation and optimal blowing distances. Radius microduct offers superior blowing performance in this market.
Low Friction Matters
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.
Class Leading
Friction Properties
At Radius, we have spent years of careful formulation and testing to achieve our class leading low friction and low static inner coatings. Our low friction compounds are home crafted, no ready-made mixes there!
And the results speak for themselves in the field where for the last 30 years we have helped our customers achieve proven consistent long install lengths thanks to our high-performance low friction coating.
