Aerial Drop Tube — ADSS
Radius ADSS (All Dielectric Self Supporting) drop tube is an all-dielectric self-supporting design comprising a single MicroGlide™ or MiniGlide™ HDPE microduct surrounded by a non-metallic aramid strength member and a UV stabilised HDPE outer jacket. The external sheath is UV stabilised for longevity and the circular profile minimises environmental loading.
This ADSS design is suitable for customer drops overhead, direct buried or alongside walls. For aerial application, it can be used between poles with spans between 50-100m, depending on environmental conditions.
All Radius microducts feature our low friction and low static permanent inner layer which delivers class-leading cable blowing performance. In addition, our microducts can be supplied with either smooth or ribbed inner walls according to your preference.
We offer ADSS in a variety of microducts (OD/ID) for the installation of drop fibre and distribution cables into the same infrastructure.
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
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.
