Polyphase short-circuiting device for LV overhead lines with bare conductors – applied from height
.
Application: from height – by hanging the self-tightening clamp to the conductor followed by the pulling down of the clamp.
Components:
-Short-circuiting subassembly 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 plug – 1 piece
Earthing subassembly consisting of:
-Coupling plug for the connection to the short-circuiting subassembly – 1 piece
-Earthing cable – 1 piece
-Earthing clamp – 1 piece
Insulating extension stick – 1 piece
Mobile earthing rod – 1 piece
Packing: waterproof bag
