The UZS VLI grounding device is designed for stationary grounding of insulated overhead lines (VLI) with a voltage of 0.4 kV. It is installed at the beginning and end of each VLI mainline, on long linear branches, at sectionalizing points, and at crossings with lines above 1000 V. This solution provides a reliable and convenient grounding system, enhancing safety during line maintenance.
