The telescopic insulating sticks PTU 20-35 F have a total length of up to 1,5 m and are made of two undetachable modules.
The telescopic insulating sticks PTU 20-35 F are components of the discharging devices for capacitors.
The telescopic insulating sticks – PTU type – are provided with a hexagonal coupling systems (fix (F) that allows the connection of other kinds of protective devices (e.g. MV/HV voltage detectors, phase clamps of the short-circuiting and earthing devices), adaptors or accessories provided with hexagonal rod of 12 mm. The stick is fixed in working position by enlargement of their tubes (from the smallest to the biggest one) and blocking them through pushing buttons.
These sticks can be used to perform different operations during the workings in substations or to the overhead lines.
