Application: from the ground, by hanging the phase clamp on the round section conductor, followed by the tightening of the clamp driving screw.
Classic / automatic phase clamps must be handled using an insulating stick according to the voltage of the installation, provided with “RO bayonet’’ coupling system.
Constructive phase clamps:
Packing: waterproof bag.
– Multipurpose modular insulating stick type PMU 110-2 B/ba / PMU 220-2 B/ba / PMU 400-3 B/ba
