DB Assemblies – HDD
Trenchless
Part of the Radius CTS Trenchless range, these heavy-duty microduct assemblies are designed for installation by mole ploughing and directional drilling where high tensile loads and extra cable protection are required.
These installation methods are most suited to grass verges and soft ground and can be very cost-effective allowing for much faster deployment than traditional trenching in addition to reducing disruption and installation time.
The metal-free assemblies comprise several MiniGlide™ thick-walled low friction microducts surrounded with a thin inner polyethylene (PE) sheath and a heavy-duty abrasion-resistant outer PE sheath.
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 CTS 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 CTS, 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.
