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

.

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

Intended use: 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.

Benefits: easy to be assembled and applied by a single user.

Components:

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

Packing: waterproof bag.

Tips: the absence of voltage on overhead conductors is checked using the subassembly consisting of the self-locking clamp – metallic telescopic stick, with a medium voltage detector fixed 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.
