Portable grounding device ZPT for overhead ground-wire cable of power lines 110-1150 kV
Grounding device is intended for worker’s protection from induced electric current shock by means of overhead ground-wire cable’s for power lines 110-1150 kV and also can be splitting.
Grounding device consists of:
• Insulating rod;
• Clamp and cramp for fixing grounding device on the overhead ground-wire cable;
• Flexible grounding conductor in transparent polymer sheath. Conductor’s ends are pressed in cable lugs. In connecting places there are sheathes from wire or polymer material for protection conductor from break.
