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 of the clamp. Self-locking automatic clamps (CAA) are attached without any dismounting options on the end of insulating sticks appropriate to the installation and the mounting position.The dismounting of clamps from overhead line conductors is performed by the handling (push) of the stick upwards, simultaneously with its vertical rotation.
Dimensions of metallic boxes used for the packing of short-circuiting devices:
-1830 x 300 x 160 mm – for the version with single-module sticks
-1030 x 300 x 160 mm – for the version with telescopic sticks (low transport volume).
Packing: waterproof bag.
