Romania – Electrical installation work – Mărirea capacității de distribuție prin modernizare LEA 110kV Târgu Mureș-Livezeni-Corunca-Fântânele, respectiv stațiile de transformare Tg. Mureș, Livezeni, Corunca și Târnăveni

Design and Execution of the work: "Increasing the distribution capacity by modernizing the 110kV Târgu Mureș-Livezeni-Corunca-Fântânele OHL, respectively the Tg. Mureș, Livezeni, Corunca and Târnăveni transformer stations", will be done according to the attached documentation. In order to achieve the proposed results, the following will be performed in this work: • Re-conduction of overhead power lines This component targets the following overhead power lines: - 110kV Fântânele Corunca OHL - in full, over a distance of 18.05km - 110kV Corunca Livezeni OHL - over a section of 1.8km; In total, we will be able to count 19.85 km of modernized OHL. • Implementation of LES instead of OHL This chapter provides for the replacement of overhead lines with underground ones, over a distance of 7.5km, as follows: - Corunca – Livezeni OHL will be introduced in underground cable over a distance of 3km; - Livezeni-Târgu Mureș OHL will be completely replaced with underground cable over a distance of 4.5km • Modernization of electrical substations:  Modernization of Târgu Mureș substation by replacing its outdated primary and secondary equipment and implementing a single sectioned busbar at the 110kV level;  Modernization of Târnăveni substation, primary and secondary circuits. In Târnăveni substation, a 110kV double busbar scheme will be implemented, and one of the bars will be sectioned by the longitudinal coupler;  Modernization of Livezeni transformer substation and equipping it with two new power transformers, of higher power than the existing ones. Livezeni substation will be modernized both in terms of primary and secondary equipment. The substation scheme will be with a single sectioned busbar at the 110kV level.  Modernization of the primary circuits in the Corunca station by replacing obsolete primary equipment in the 110kV outdoor station.
