Polyphase short-circuiting device for LV overhead lines with bare conductors – applied from height

.

SKU: Msp - 1 - nxSf/lf - Sp/lp - O/p
Category:

Intended purpose: earthing and short-circuiting of bare conductors of LV overhead lines.

Application: from height (from the ladder, from the basket) – by hanging the self-tightening clamp to the conductor followed by the down pulling of the clamp.

Components:

The short-circuiting subassembly is provided with:

  • Self-tightening clamp with insulating stick – “n” = 4 … 7 pieces
  • Short-circuiting cable – 3 … 6 pieces
  • Connection cable to the earthing subassembly provided with socket – 1 piece

The earthing subassembly consisting of:

  • Plug for the connection to the short-circuiting subassembly – 1 piece
  • Earthing cable – 1 piece
  • Manual earthing clamp – 1 piece
  • Insulating extension stick – 1 piece
  • Mobile earthing clamp – 1 piece

 

Packing: waterproof bag
