Three phase short-circuiting device for MV overhead line – application from height – CAA clamp

.

SKU: Msp CAA - AST - 3xSf/lf - Sp/lp - O/p
Category:

Application: from height, by hanging the automatic self-locking clamp (CAA) on the conductor, followed by pulling down the clamp.
Self-locking automatic clamps (CAA) must be handled with an appropriate insulating stick for the installation and mounting position.
According to the selected type of mounting piece, CAA automatic clamps can be applied simultaneously (using the clamp applicator) or successively (using the mounting adaptor).

Components:

  • Self-locking automatic clamp (CAA) – 3 pieces
  • Short-circuiting cable – 3 pieces
  • Earthing cable – 1 piece
  • Earthing clamp – 1 piece
  • Clamp applicator (PAS/E or PAS/C) or mounting adaptor (AM/E or EM/C) – 1 piece
  • Removal hook (CDA/E or CDA/C) – 1 piece
  • Mobile earthing rod – 1 piece

Packing: waterproof bag.
