Single-phase short-circuiting device for the railway contact line

.

SKU: Msp - CrTf - Sp/lp- Fc/ps
Category:

Application: from the ground, by hanging the clamp on the contact line, followed by tightening the clamp driving screw.
The classic CrTf phase clamp must be handled with an insulating stick according to the voltage of the installation.

Components:

  • Classic reduced clamp for railway transportation (CrTf) for the connection to the contact line  – 1 piece
  • Earthing cable – 1 piece
  • Manual clamp for the connection to the rail (CLPS) – 1piece

Packing: waterproof bag.

Tips: considering the positioning height of the contact line from the ground, for the application of the phase clamp to the contact line we recommend the use of PMU 400-3 B/ba sticks or of 6 metre long telescopic sticks PTU AS-400-4-C + hexagon-bayonet adapter ACMIT/C.
