According to the test results, the Izolyator high-voltage bushing with RIP insulation was approved for use at power facilities in Brazil

From 24 April to 9 May 2023, in Brazil, with the participation of TDM Service & Solution engineering company, type tests of the 600 kV Izolyator RIP transformer bushing, designed for the Teles Pires Transmission power line, were successfully completed.

TDM Service & Solution is a Brazilian engineering company active in the electricity sector. The company provides services for installation, commissioning, maintenance, diagnostics and overhaul of transformer equipment at medium and high voltage substations. TDM Service & Solution is also represented in other Latin and North American countries.

Teles Pires Transmission is a 500 kV line for the transmission of electricity from hydroelectric power plants, including the Teles Pires power plant in the central region of Brazil (Mato Grosso state), to the southeast of the country and part of the National Interconnected System (Sistema Interligado Nacional). Construction, operation and maintenance of power facilities of the line are carried out by specially created companies Guaraciaba Transmissora de Energia S.A. and Matrinchã Transmissora de Energia S.A. Both companies are controlled by the State Grid Brazil Holding, the Brazilian branch of the State Grid Corporation of China, and Companhia Paranaense de Energia, a Brazilian utility the state of Parana.

The tests were carried out in the laboratory of the Electric Energy Research Center located in Nova Iguaçu in the state of Rio de Janeiro.

The Brazilian Electric Energy Research Center (Centro de Pesquisas de Energia Elétrica — Cepel) is engaged in experimental research, development and testing of technical solutions for the development of the national electrical engineering and power industries. The head office of the Cepel is located in Rio de Janeiro.

The Izolyator Group was represented by the Senior Sales Manager — Asia & America Denis Grankin at the tests.

According to the test results, for the first time, a high-voltage bushing with internal RIP insulation manufactured by the Izolyator Group was approved by the Cepel for use at power facilities of the National Interconnected System (Sistema Interligado Nacional).

Representatives of TDM Service & Solution and Izolyator Group are satisfied with the results — the tests were completed successfully!

The event came as an important step towards the development of Russian-Brazilian cooperation in such key sectors as electrical engineering and power industry.

The attention that the leadership and relevant industry organizations of Brazil pay to large projects to modernize and develop the country's power grid infrastructure gives that fact an even larger weight. According to the current ten-year plan for the development of the power sector (Plano Decenal de Expansão de Energia), 6.122 kilometers of power transmission lines and substations with a total transformer capacity of 400 MVA are planned for erection in the near future.
