Microduct Assembly 7/3.5 + 14/10mm

TWD 7/3.5 + 14/10mm, Hybrid, KNZ

For direct burial
7/3.5 mm and 14/10mm microducts
16-way, 19-way and 22-way assemblies
Low friction inner surface

The thick walled microduct bundles consist of a number of microducts with an inner low friction surface that enables installation of air-blown fiber units, nano cables or micro cables. The thick inner wall of the microducts allow for installation directly into the ground without the need for additional protection.

The duct assemblies are available in configurations with 16, 19 and 22 microducts.

7/3.5 mm microducts are optimized for installing air-blown fibres and nano cables, and the 14/10 mm microducts are for nano and micro cables. The microducts have a low-friction inner surface for the best blowing performance.

Microducts and outer sheath: HDPE

Marking	Duct assemblies have markings showing the type and tube length. The individual microducts are identified by their colors. Different colours are used according to KNZ standard. For duct assemblies with >12 ducts, the first 12 coloured ducts are marked with “1” and the following ducts are marked with “2”. The assemblies come with a green outer sheath, or with a customised outer sheath colour by special order.
