Application: from the ground, by the successive lifting of each clamp, hanging of the automatic self-locking clamp (CAA) on the conductor, followed by the pulling down of the clamp, automatically detached from the mounting adapter.
Considering the weight of the phase clamp, connected to the earthing conductor and the positioning of the overhead conductors at approx. 9 m from the ground, the application of clamps with the 9 m multipurpose telescopic insulating stick type PTU-AS-400-6-c is difficult to be performed in bad weather conditions.
In order to facilitate the application of clamps on overhead conductors, it is recommended to use the pulley system for the lifting of the short-circuiting clamps from the ground.
Components:
- Self-locking automatic clamp (CAA) – 3 pieces
- Earthing cable – 3 pieces
- Earthing clamp – 1 piece
- Mounting adaptor (AM/C) – 1 piece
- Removal hook (CDA/C) – 1 piece
- Mobile earthing rod – 1 piece
Packing: waterproof bag.
