Temporary short-circuiting and earthing device, installed from the ground, for LV flag-type lines
Use
The DMCCTBTARFR device is designed for short-circuiting and earthing low voltage flag-type lines, with 5 or 6 conductors (1 neutral, 3 phases, 1 or 2 Public Lighting). It is manipulated from the ground with a telescopic insulating stick. The installation of the device must be done just after the no-voltage checking.
The DMCCTBTARFR device is composed of 2 sticks made of aluminium, on which are mounted the conductive aluminium U-profiles, equipped with 4 clamps. The first stick puts the 3 phases and the neutral in short-circuit, and the second the public lighting, by connecting itself to the last phases, beforehand short-circuited with the neutral. All the device can be earthed by a copper cable, linked to the first conductive stick.
These 2 conductive sticks are fitted on the insulated stick by a U/Tulip tool. Then, the insulating stick can be used for any operation once the line is correctly earthed.
The 6 conductors of the line can be short-circuited in only 2 operations.
