LSZH Single Microduct
Low Fire Hazard – High Performance
Equivalent To
Safety First
Radius CTS Low Fire Hazard (LFH) microducting is manufactured to the highest standards, with prime Low Smoke Zero Halogen (LSZH) material that is tested by BASEC to BS EN 50575 and meets an informal CPR class equivalent to B2: s1: d2: a1 in accordance with EN 13501-6 : 2014. The ducting was tested without cable. As a result, this reduces the amount and density of the smoke and toxic and corrosive gasses emitted during the combustion process.
Our LFH single microducts and assemblies can be CE marked and fully comply with LVD 2014/35/EU.
LFH microducts can be supplied as single loose tubes or as sheathed assemblies of various configurations and feature our class-leading low friction inner lining.
Our LFH microducting perfectly combines safety, optimal blowing distance and ease of installation.
Understanding CPR Fire Classification
The Construction Products Regulation (CPR) is a key legislation for fire safety in buildings, designed to help save lives and protect buildings. This regulation requires that cables come with a declared fire performance rating. The specifications for this rating fall into four categories:
- Reaction to fire Â
- Smoke production
- Flaming Droplets
- Acidity
Performance is classified into hierarchical Euroclass levels where B2 and C are those with maximum performance against fire, providing maximum protection to people and equipment. Cables belonging to classes D and E have a more basic level of safety.
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.
