High Voltage Overhead (LEA) and Underground (LES) Power Lines

Major maintenance LEA 400 kV Rosiori - Gadalin, phases: ET, DALI, PT + CS, DTAC

In the first stage, based on the technical characteristics of the line, the technical expertise of the OHL elements was performed: poles, sockets, foundations, active and 
protective conductors, clamps and fittings, insulator chains. The expertise was made on the basis of visual observations, computerized verification calculations, mechanical 
strength of the poles and by mechanical and electrical tests of some samples of conductors, clamps, fittings and insulators taken from the line. 
Also, by performing some topographic measurements and some calculations, the coexistence of 400kV OHL with other objectives (crossings and approximations) was 
analyzed. At the end of the expertise, it was proposed to carry out works to remedy the deficiencies found.
In the following phases, DALI, PT + CS were developed and detailed from a technical and economic point of view in accordance with the legal content norms, the works 
approved by the Technical Expertise.
