In order to guarantee the optimal quality and state of the insulator chains of the first 500 kV transmission line of Bolivia Carrasco – Santivañez, Ende Transmission has carried out a Important status measurement work of the porcelain insulators chain with the line energized. For this, a new technology was used for the diagnosis of the state of the insulators of the chains.The equipment used for this measurement is a new instrument called positron.

Porcelain insulators are essential elements in high voltage transmission lines, that They provide efficient electrical insulation that prevents current leakage and guarantees system integrity.Its relevance becomes especially critical in adverse conditions, such as Storms, extreme fluctuations of temperature, pollution and other climatic events.

A specialized linen team of the company was in charge of the measurement work with the equipment Positron.This team measures and records the electric field through a scan that makes it long of the insulators chain and reveals all its conductive defects, allowing a job Line personnel insurance.In addition to providing an early diagnosis of the state of Insulators Without the need to disregard the line, it helps to identify possible problems before convert In critical failures.During the measurement security protocols were followed for guarantee The correct operation of the measurement equipment and obtaining reliable results.

The maintenance of porcelain insulators in high voltage transmission lines is a activity Very important to ensure the reliability and availability of the country’s transmission system.

The National Electricity Company (Ende Corporation), through Ende Transmission, made the change of Equipements primary in the Vinto substation, located in the department of Oruro, to strengthen the transport of energy electric and avoid any type of unexpected cuts in the service.

According to the renewal plan faced by the transmission, the change and improvement of 6 was made 115 kV park current transformers, 2 three -phase switch of 69 kV and 3 park Capacitive line output voltage transformers to the 69 kV mining company (EMV).

The vinto substation is one of the oldest facilities that composes the interconnected system National (SIN), entered operation more than 40 years ago and has been updated and Improvement, to guarantee the reliability, stability and efficiency of the electrical system.The Validity of the operation of this electrical substation is a sample of the correct administration Operational by Ende.

The state electric current currently has one of the more electricity transmission systems robust and efficient of the region and incorporates new technology to expand the transport capacity electric, also dedicates an arduous work to the maintenance of equipment, which has an important Tour of its operation.

UNICOM ENDE / 19-03-2024.- The National Electricity Company (Ende Corporation) faces the construction of the project “Transmission line in 500 kilovolts (KV) Carrasco – the associated gaps and substations”, being The second line of electric transmission in extra high voltage of Bolivia, which to date reports an advance of 77% and will allow strengthen the electricity supply in the departments of Cochabamba and Santa Cruz, in addition to providing the capacity of Electric power transport needed to market, in the future, electricity to the neighboring country from Brazil.

The project is in charge of Ende Transmission and includes the construction of a line of 186.30 kilometers long, From the Carrasco substation (extension), located in the municipality of Entre Ríos in the province Carrasco del Cochabamba Department, until the Las Grechas (new facilities) substation, located at 35 kilometers south of The city, close to the population of Basilio, in the Cordillera province of the department of Santa Cruz. Currently performs the construction of foundations, the assembly of structures and the laying of conductors in the line, as well as All civil works and equipment assembly in Carrasco substations and gaps.

The highlights of this second line in 500 kV is that, all the line designs and Substations associated, were carried out with an engineering of Ende Transmission, as well as in the execution of this work, it is used 100% national cut and labor technology, consolidating the capacity of professionals Bolivians in the field electric.

The line will allow the creation of a large capacity for electricity transport, which will interconnect The eastern and central areas of the National Interconnected System (SIN), strengthening the supply electric and allowing to have the generation surplus at the Las Grechas collector node, for the future export.

Ende will continue working to strengthen the national electrical system.With the construction of the Second line of electric transport in 500 kV, Bolivia consolidates its electrical system as one of the safest and Reliable of the South American region.
