SKU: Msp - CAA - AST - 3xSf/lf - Sp/lp - O/p - E (model ENEL); Msp - CAA - AST - 3xSf/lf - Sp/lp - O/p - T (model cu prăjini telescopice)
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) are attached without any dismounting options on the end of insulating handling sticks, appropriate to the installation and the mounting position.

Components:

  • Self-locking automatic clamp (CAA) with handling stick – 3 pieces
  • Short-circuiting cable – 3 pieces
  • Earthing cable – 1 piece
  • Earthing clamp – 1 piece
  • Mobile earthing rod – 1 piece

Handling stick type:

  • single module (version E)
  • telescopic with two sections (version T)

Packing:

Dimensions of metallic boxes used for the packing of short-circuiting devices:

-1830 x 300 x 160 mm – for the version with single module handling sticks

-1030 x 300 x 160 mm – for the version with telescopic handling sticks (lower volume for transport).
