UNICOM/ENDE TRANSMISIÓN: ENDE TRANSMISIÓN SUCCESSFULLY CARRIES OUT THE RECERTIFICATION COURSE OF LIVE LINE MAINTENANCE FROM 230 to 500 KV

ENDE Transmisión, a subsidiary of ENDE Corporación, has as its main activity maintaining the reliability and normal operation of the Transmission Network in the National Interconnected System (SIN), with high performance index values. With this purpose and within the framework of its 2021 management training plan, it has successfully completed the Live Line Maintenance Recertification Course from 230 to 500 kV.

This important course had the participation of specialized and outstanding line maintenance personnel from all the Regional and Sub-Regional offices of ENDE Transmisión (Cochabamba, Oruro, La Paz, Beni, Santa Cruz, Trópico, Potosí, Sucre, Tarija, Uyuni , San Borja and Gran Chaco), who demonstrated high capacity, responsibility and security in the execution of this type of work.

The course was carried out in a first theoretical stage virtually from October 13 to 14, 2021 and in a second practical field stage in 230 and 500 kV structures from October 18 to 29, 2021. For this course, it was counted with the presence of 2 instructors with vast experience in live line maintenance from the Brazilian CTST company (Mr. Marcelo Carvalho and Mr. Raimundo Baia Everdosa); This theoretical-practical activity allowed keeping the skills up-to-date and consolidating the knowledge of the live line maintenance technical staff.

The theoretical-practical scope of said course was as follows:

  • Review and instruction on philosophy and principles of live online maintenance.
  • Planning and methodology of live line maintenance work for Transmission overhead lines.
  • Risk analysis and electrical safety distances.
  • Materials, Tools and Equipment Technology.
  • Inspection, testing, cleaning and storage of tools and materials.
  • Safety in insulating equipment and conductive clothing / suit.
  • Entry to potential.
  • Entrance to potential through insulating ropes, chair, baskets or ladders.
  • Replacement of insulators in 230 kV voltage structure, in single triplet and double bundle of conductors in horizontal phase arrangement.
  • Replacement of insulators in 230 kV suspension structure, in single triplet and double bundle of conductors in horizontal phase arrangement.
  • Replacement of insulators in suspension structure 230 kV, double triplet and double bundle of conductors in vertical phase arrangement.
  • Replacement of insulators in 230 kV voltage structure, double triplet and double bundle of conductors in vertical phase arrangement.
  • Inspection and analysis of tension and suspension structures at 500 kV, for implementation of live line maintenance methodology.

The team of instructors of the CTST company in Brazil, in their technical report of the activity carried out, highlighted the participation of the personnel as highly competent in the technical, as well as human.
