Single-phase short-circuiting device for HV overhead line – CAA clamp

.

SKU: Msp CAA - Sp/lp - O/p ; Msp CAA - Sp/lp - O/pr
Category:

 

Two application methods depending on the operator’s positioning compared to the conductor:

  • By hanging the clamp on the conductor followed by pulling down (if the operator is positioned under the conductor),
  • By pushing and pressing the clamp on the conductor (if the operator is positioned above the conductor).

Components:

  • Self-locking automatic clamp – 1 piece
  • Earthing clamp – 1 piece
  • Earthing cable – 1 piece
  • Mounting – dismounting adapter (AMD/E) – 1 piece/set of 3 short-circuiting devices

Packing: waterproof bag.

Tips: we recommend the use of earthing clamps with scraping jaw (code CLPBR-12 or CLPBR-16) to clean and remove layers of oxides, dirt and protective paint from the metallic brackets of overhead line poles, in order to obtain appropriate contact resistance.
