Microduct thick-walled DB 7/3.5 for direct laying in ground, MelbyeArt. no.: 5044258
Holds up to 24 micro-tubes of dimensions 5/3.5mm as well as also for DB24 a micro-tube of 10/8mm. The tubes are manufactured as a low friction pipe and have an inner layer specially designed to reduce friction against the fibre. The tubes are transparent so that the components in the tube are visible. In order to identify the tubes, they have different colours and are numbered. In each tube, up to 12 fibres can be installed.
The micro-tubes are protected against water and mechanical loads by an aluminium barrier, alternatively a sealing tape, and one (DB1) or two (DB2-DB24) PE layers. For DB1, the PE layer is approx. 3mm and for other DB-configurations, the inner PE layer is 1.6 mm and the outer approx. 3mm. DB2-DB24 has a ripcord string above the inner PE layer to open the pipe without damaging the tubes.
Design
1. 5/3.5 mm tubes with a low-friction type inner layer
2. Ripcord, two for DB1 and one for the remaining configurations
3. Aluminium jacket or sealing tape
4. Inner HDPE jacket (not DB1)
5. Orange outer HDPE jacket
The pipe is meter-marked.
