EMC study for comparison in accordance with current regulations between installation of underground cables in single-core mode and installation of visible helically routed cables

The purpose of the study project is to assess whether or not, with regard to the potential interference that can be caused by electrical conduits to the telecommunications infrastructure, in the case of adopting an electrical conduit consisting of three single-core MV cables installed in a trefoil or in a plane, the effects are comparable to those of an electrical conduit consisting of an equivalent trio of MV cables installed in a visible helix.

The new Electronic Communications Code, which entered into force on 24 December 2021 (Legislative Decree no. 207 of 8 November 2021 – Implementation of Directive (EU) 2018/1972 of the European Parliament and of the Council of 11 December 2018 establishing the European Electronic Communications Code, hereinafter ECC) in Art. 56 (Electricity installations and pipelines, buried metal pipes – Interference – ex art. 95 Code 2003) prescribes, for the construction, modification or relocation of any electrical energy pipeline, the issuance of a prior authorisation by the Inspectorate of the Ministry, competent for the territory; this authorisation, in the case of visible helically routed cables, is replaced by a certificate of conformity. In this context, the overall objective of the project is to carry out a study to assess, in relation to the potential interference that can be caused by electrical conduits to telecommunications infrastructures, whether, in the event of adopting a different Medium Voltage (MV) cable-installation configuration from the one traditionally used by the company e-distribuzione (DSO of the ENEL group operating in Italy), the effects are comparable or whether there are significant differences between the two types of solutions.
