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:

Intended use: earthing and short-circuiting of conductors for MV overhead lines.

Application: from height (from the ladder, from the basket), by the hanging of the automatic self-locking clamp (CAA) on the conductor, followed by the pulling down the clamp.

Self-locking automatic clamps (CAA) must be handled using an insulating stick appropriate to the installation and the 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 adapter).

Components:

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

Packing: waterproof bag.

Operations must also include the following equipment:

– connecting insulating stick type PMU 20-1 B/ba or PMU 20-1 B/ba, provided with ‘’Ro bayonet’’ coupling system.

– telescopic insulating stick type PTU 20-35 F, PTU 20-110 F or PTU 20-45-110F, provided with ‘’hexagon 12’’ coupling system.

Tips: the coupling ends of the applicator / adapter and of the removal hook must be selected so that they can be adapted to the coupling system of the used insulating stick.
