Introduction
Madison Technologies provides tube bundle assemblies in Direct Install (DI), Direct Bury (DBT) and Low Fire hazard (LFH).
System Features
-
Flexibility - When wrapped around a 10d mandrel (where d = tube diameter) there is no kinking or damage and an appropriate diameter ball passes completely through the microduct.
-
Pressure - Micro duct withstands 17 bar air pressure underwater for 2 hours without leaks.
-
Friction - Low friction lining material used to increase fibre blow distance.
-
Crush - After a 1000N load (used on Polyethylene microducts) and 400N load (used on Low Fire Hazard mirco ducts) for 1minute, the residual deformation of the microduct does not exceed 15% measured within 1 minute
Features
Direct Install Microducts (DI)
The assembly is surrounded with an aluminimum layer, bonded inside a sheath of black MDPE for direct-in-duct installation, not suitable for direct burial. A rip cord is pre-installed along the entire length, under the sheath, to rip through the aluminium and sheath using correct procedure.
