Three-phase short-circuiting device for MV overhead line – application from the ground – self-locking clamps

.

SKU: Msp - N - AS - 3x35/10 - O/p
Category:

Intended use: earthing and short-circuiting of MV overhead line conductors placed maximum 10.5 m from the ground.

Application: from the ground, by hanging the self-locking clamps mounted at the end of metallic telescopic sticks on overhead conductors, using the insulating stick included in the short-circuiting device.

Components:

  • Metallic telescopic stick with self-locking clamp – 3 pieces
  • Insulating stick with two modelues – 1 piece
  • Metallic drum for the transportation of earthing cables – 1 piece
  • Earthing cable, l=10m; S=35 mm – 3 pieces
  • Manual earthing clamp – 1 piece
  • Mobile earthing electrode (peg) – 1 piece

Packing: waterproof bag.

Tips: the absence of voltage on overhead conductors is checked by means of the subassembly consisting of the self-locking clamp – metallic telescopic stick, with the voltage detector DTCIER/P 635 kV mounted in the special part at the end of the insulating stick consisting of two modules. The voltage detector is not included in the product set.
