Universal polyphase short-circuiting device for LV overhead lines (Aerial Bundle Cables (ABC) and bare conductors)
.
Aerial Bundle Cables (ABC) provided with COT 10-95 A (ROMANIA) voltage connectors: use the short-circuiting subassembly, the earthing subassembly and the mobile earthing rod.
Aerial Bundle Cables (ABC) provided with DPS (ROMANIA) voltage connectors: use the short-circuiting subassembly, in whose plugs are mounted the coupling adaptors to DPS connectors (from the kit), the earthing subassembly and the mobile earthing rod.
Overhead lines with bare conductors: use the clamps with screw locking and insulating stick coupled to the plugs of the short-circuiting device, the earthing subassembly and the mobile earthing rod.
Components:
Short-circuiting subassembly provided with:
-Coupling plug for voltage connectors type COT 10-95 A – “n” = 4…7 pieces
