Polyphase short-circuiting device for LV OHL lines with twisted conductors

.

SKU: Msp - T - 1 - nxSs/0,7 - Sp/lp - F/p
Categories: ,

Intended purpose: earthing and short-circuiting of twisted conductors of LV OHL lines.

 

Application: from height (from the ladder, from the basket) – by direct connection (or by means of adapters) of the short-circuiting device subassembly plugs to the sockets of the voltage connectors mounted permanently on overhead conductors.

Components:

The short-circuiting subassembly consisting of:

  • Coupling plug for voltage connectors type COT 10-95 A – „n” = 4…7 pieces
  • Short-circuiting cable – 3…6 pieces
  • Connecting cable to the earthing subassembly – 1 piece

The earthing subassembly consisting of:

  • Plug for connection to the short-circuiting subassembly – 1 piece
  • Earthing cable – 1 piece
  • Manual earthing clamp – 1 piece
  • Mobile earthing electrode (peg) – 1 piece
  • Set of coupling adapters to DPS* connectors (see NOTE) – “n” – 4…7 pieces

Packing: waterproof bag.
