Eurico Ferreira Portugal concluded successfully the Uprating works in the Very High Voltage (VHV) Overhead Power Transmission Line, of 400 kV, between Falagueira and Cedillo, for REN - Redes Energéticas Nacionais.
This project is part of National Power Transmission Development Plan, it aims to increase the capacity of this transmission line, allowing its exploitation at a temperature of 85°C.This OPL is one of those that allows the interconnection with the Spanish power grid.
The project started May 2017 and lasted 4 months.
This Uprating contemplated the substitution of 14 prismatic modules, 29 supports and other 9 had been reinforced. Strain insulators, 14 Km of conductive cables and 24 km of guard wire were also substituted. The team also repositioned 24 km of Optical Ground Wire (OPGW) and 6 km of ground wire conductors.
Facing a tight deadline, the Eurico Ferreira’s team challenged major difficulties on the field, namely the high temperatures, closer to 40ºC, where fires had been registered.
Nonetheless, the resiliency and team’s responsiveness stood out and all the obstacles were surpassed, allowing the team to reach the objectives and ensure the quality of service and de subsequent client’s satisfaction.
