The first time installation of Izolyator-AKS cable accessories

On 24 September 2022 the products of the Izolyator-AKS high-voltage cable accessories plant were installed at a power facility in the Minsk region in Belarus for the first time. The installation of three terminations on the cable line of the 126 kV Ostroshchitsky Gorodok substation, which is being reconstructed by the Minsk Electric Networks, was successfully completed.

 Minsk Electric Networks serve 0.44–800 kV power grid, which provides centralized power supply to all sectors of the national economy and the population in the Minsk and Pukhovichi administrative districts of the Minsk region, on an area of   4.77 thousand square kilometers. In addition, Minsk Electric Networks serves all 40.5–363 kV transmission lines in Minsk. Minsk Electric Networks is a branch of the Minskenergo Republican Unitary Enterprise of the Electric Power Industry, which is fully responsible for the production, transmission, distribution and sale of electric and thermal energy, aimed at ensuring reliable and uninterrupted power supply to consumers in Minsk and the Minsk region.

The installed outdoor terminations with composite insulator IKM-126 are sealed armature designed for air connection of cable lines with elements of the power supply system and are installed on cables with XLPE insulation.

For the first time Izolyator-AKS cable accessories were installed at a power facility: three IKM-126 outdoor termination mounted on the cable line of the 126 kV Ostroshchitsky Gorodok substation of the Minskenergo Republican Unitary Enterprise of the Electric Power Industry in Belarus

The installation site was visited by the Minister of Energy of the Republic of Belarus Viktor Karankevich, which speaks for the importance of this power facility for the infrastructure of the Minsk region.

This installation procedure features the lifting of the pre-assembled on the ground armature with its subsequent installation on the seats of the power transmission line support.

The assembly of the terminations was carried out at prepared work stations. The lifting was done using a special locking device.
