Consideration of the topic ‘High-voltage bushings with RIN-insulation’ began with a report by Alexander Slavinsky, which, based on an analysis of objective factors, showed clear advantages of RIN-insulation and the prospects for mass use of high-voltage bushings with this type of internal insulation.

he speaker noted that currently Izolyator already supplied high-voltage bushings of this type to power grid facilities of Russia and Europe. These are RIN-insulated bushings 110–330 kV for transformers, 35–110 kV for switches, and also 220 kV bushings for current-limiting devices operating on the basis of high-temperature superconductors at minus 200 °C.

Representatives of the electric grid companies Krymenergo and Sevastopolenergo stated they have successful experience of operating high-voltage bushings with RIN-insulation and intentions of further purchases.

Representative of the Federal Grid Company of the Unified Energy System, a member of Rosseti Group, informed the meeting participants about the start of pilot operation of the 220 kV bushing with RIN insulation installed on a transformer in May of this year.

Taking into account all the above, as well as successful certification of high-voltage Izolyator RIN insulation bushings by Rosseti Group, the Technical Council decided to purchase such bushings for 35–500 kV for installation on transformers, autotransformers, oil circuit breakers and reactors, and also to form emergency reserve.
