(New)
Background and justification
The need to save costs and to reduce time for the construction of underground
infrastructures and for the installation of Telecommunications cables and the
requirement to reduce the social impact of the excavation work, moves the
operating companies to use new construction and installation techniques.
The final goal is to install cables in small trenches, directly buried or in
small ducts; as a function of the dimension of the trench, the new techniques
can be referred as mini-trench (5-10 cm wide, 30-35 cm deep) or micro-trench
(6-8 cm deep and 1-2 cm wide). The second one can be considered a general
application of the Micro Cabling System patented by Siemens.
These new techniques can require new cables and components (splice closures).
Recommendations to address the issues of these new installation techniques
and the related cables and components are required to aid their establishment.
