UNP-10B “BOOMERANG” AND UNP-10 (WITHOUT REEL)

UNP-10B “BOOMERANG” AND UNP-10 (WITHOUT REEL)

UNP-10B and UNP-10 are designed for emergency earthing of overhead lines through an overhead line short-circuit by means of a jumper connected to the “grounding” in all cases requiring instant voltage disconnection of overhead lines for rescuing of those affected by electric shock. The device comprises the active part (operational), earthing part with a cramp, insulating wire weighted at the end, and earth rod EZ-1.
Permissible operating temperature is from –25 Cto +55 оC, at air relative humidity up to 80% at 25 оC.
