DB Assemblies – Wall Mounted
Trenchless
These assemblies are designed to be buried directly into prepared ground or wall mounted with Radius wall mounting brackets. They comprise of several low friction MiniGlide™ or MicroGlide™ PE microducts surrounded by a tight inner polyethylene sheath and a heavy-duty outer polyethylene sheath.
Ripcords are pre-installed to safely remove the inner sheath without damaging the microducts.
The heavier direct bury construction lies flatter in trenches and has more resistance to localised bending. It also offers additional resistance to tensile loads and on-site handling.
These assemblies are suitable for situations in damp, mildly aggressive environments for the hanging of subduct at intervals not greater than 900mm.
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.
