Romind - Three-Phase Short-Circuiting Device
Three-phase short-circuiting device for MV OHL line – application from the ground or height – CAA clamp. Intended use: earthing and short-circuiting of conductors of MV overhead line conductors.. Application: from the ground or from height (from the ladder, from the basket), by hanging the self-locking clamps (CAA) on the conductor, followed by the pulling down the clamp, which is automatically removed from the clamp applicator.
Automatic self-locking clamps (CAA) must be handled with insulating sticks appropriate to the installation and mounting position.
The following sequence of operations shall be observed:
1. By means of the earthing subassembly, one conductor of the line is earthed
2. By means of the short-circuiting subassembly, the three conductors of the line are short-circuited, starting with the conductor earthed in the previous operation.
Components:
The short-circuiting subassembly for 3 overhead conductors includes the following components:
- Automatic self-locking clamp (CAA) – 3 pieces
- Short-circuiting cable – 2 pieces
The earthing subassembly includes the following components:
- Automatic self-locking clamp (CAA) – 1 piece
- Earthing cable – 1 piece
- Manual earthing clamp – 1 piece
- Clamp applicator (PAS/E sau PAS/C) – 1 piece
- Removal fork (CDAU/E sau CDAU/C) – 1 piece
- Mobile earthing electrode (peg) – 1 piece
Packing: waterproof bag.
Other equipments to be used:
– connectable insulating stick type PMU 20-1 B/ba or PMU 20-1 B/baS (for application from height), provided with ‘’RO bayonet’’ coupling system
– telescopic insulating stick type PTU 20-35 F, PTU 20-110 F or PTU 20-45-110F 9for application from height), provided with ‘’hexagon 12’’ coupling system
– telescopic insulating stick type PTU-AS-400-6-c (for application from the ground), provided with ‘’hexagon 12’’ coupling system
Tips: coupling ends of the clamp applicator and of the removal fork must be selected to be adapted to the coupling system of the insulating stick used.
