In order to strengthen the integrity of high voltage structures and thus guarantee the security and continuity of the supply of electricity in the eastern system, Ende Transmission did important maintenance work on the La Belgica transmission line – GUARACACHI 230 KV.

During routine technical inspections that were carried out during the months of November and December of The 2023 management, indications of corrosion in the structures were identified, a phenomenon considered normal given the aging of them and the climatic conditions of the environment, taking into account that the Transmission line entered into operation in 1989, and to date it has 34 years of continuous operation.

The maintenance work was carried out with the energized line and essential works of Sanding, cleaning and painting of 30 structures.This process included cleaning by mechanical abrasion and Chemistry, followed by coating with high -performance alipheic polyurethal base paint maritime degree, resistant to pollutants and UV rays to prevent corrosion and ensure durability of structures.Maintenance works not only seek to preserve existing infrastructure, but also guarantee the continuity of the operation on the line, thus contributing to the efficient operation of the national interconnected system (SIN).

The maintenance was completed without incident registration, complying with ISO 12944; Bolivian professionals implemented rigorous security measures, given the importance of the line transmission for the SIN.The height activities that were mostly carried out are highlighted With the energized line, dividing the intervention by sectors into the structure according to its danger. This particular fact consolidates the capacity of workers, since the entire line and The associated substations are operated and maintained with the employment of national labor.
