Pulley system for lifting from the ground the phase clamps, CAA type, of MV overhead line three-phase short-circuiting devices

Intended use: application from the ground of mobile three-phase short-circuiting devices code Msp-CAA-AS-3xSp/lp-O/p on MV overhead lines.

Directions of use: lifting and applying the phase clamps on overhead conductors as follows:
– the CAA type lifting clamp with pulley (1), mounted in stick extension piece (3), fixed in the coupling system of the telescopic insulating stick PTU-AS-400-6c, is lifted and applied beforehand on the highest phase of the MV overhead line.

– each phase clamp of the short-circuiting device is fixed successively in the stick extension piece (3), then, by pulling the lifting cord (2) (passed through the pulley of the lifting clamp (1)), the phase clamp, the earthing cable and the telescopic insulating stick are easily lifted at the necessary height for applying the phase clamp on the overhead line conductor.

The dismounting of phase clamps from the overhead line conductor is performed using the CDA/C dismounting hook (4), assembled directly in the coupling system of the telescopic insulating stick.

Components:
-CAA lifting clamp with pulley (1) – 1 piece
-Lifting cord (Ø 8 mm) (2) – 1 piece
-Stick extension piece (3) – 1 piece
-Dismounting hook CDA/C (4) – 1 piece
-Winding support for the lifting cord (5) – 1 piece
