High voltage indicator UVNU-10 DSH univers. for voltage detection without climbing the pole (light-sound indication built-in power source self-test) Antitok D413802

High voltage indicator is designed to detect the presence or absence of voltage on the current-carrying parts of 10 kV AC overhead lines through direct contact with these parts without climbing the tower, directly from the ground surface. The presence of AC voltage is notified by an acoustic and light signal.
