The pantograph disconnector consists of one or three poles. Each pole consists of one support insulator, one rotating insulator, the pantograph mechanism and a counter contact.

   Pantograph disconnectors are the best solution for busbar selection, since they can ensure isolation/connection directly across the vertical gap between lower and upper busbar.

   Güral TFPK, TFPA and TFP Series Pantograph Disconnectors are high performance and compact solutions for high voltage systems. With variations designed to serve for a wide range of system voltages, Güral TFPK, TFPA, TFP Series Pantograph Disconnectors currently operate worldwide at system voltages from 72.5kV to 550kV.

   The flexibility of the design of Güral TFPK, TFPA, TFP Series Pantograph Disconnectors allows almost any custom solutions requested by the client, including earthing capability of load, insulation levels, driving variations and construction assembly types.

   Pantograph disconnectors can be fitted generally in crosswise layouts.
   

   The disconnectors can be equipped with insulators in accordance with IEC, ANSI or DIN specifications.
   

   The pantograph mechanism is installed on the support insulator and transfers the movement of the rotating insulator to the arms of the pantograph disconnector. The mechanism is housed in an aluminium cast enclosure, protecting it against pollution and ice. The mechanism compensate the weight of the pantograph arms are also installed in this housing.

   Each pantograph mechanism is equipped with four high strength aluminium arms to ensure a rigid construction with a very high short circuit rating. Current is transferred through the joints by multi-contact system having high and homogenous current carrying capability.

   The main contacts are made of copper having special shape with a silver plated surface. The counter contact consists of two vertical aluminium tube and a horizontal silver-plated copper tube which has to be connected to the busbar system.
   

   Güral pantograph disconnectors may be equipped with one earthing switch, which can be built-on to the pantograph disconnector.
   

   The pantograph disconnectors and/or earthing switches can be single-pole or gang operated by means of a motor-operated drive mechanism or a manual-operated drive mechanism.

   In case only one drive mechanism is used for gang operation, the poles are interconnected by means of coupling rods.

   MD Series motor drives and HD series hand drives have aluminium housings and special design auxiliary switches. MD series motor drives also have manual operation by a crank.
   

   The pantograph disconnectors are designed and tested in accordance with latest IEC standards.
   

   The pantograph disconnectors and earthing switches are pre-assembled and adjusted in our workshops as complete as possible.

   The construction is designed so that all disconnectors can be installed and adjusted at site very easily without the need of any special tools.  Güral provides installation instructions and assembly drawings.
   

   The disconnectors and earthing switches supplied by GÜRAL are designed so as to ensure that they are maintenance free.

   However, to guarantee a long and trouble-free service period, we advise that a visual inspection of the contacts and bearing points be carried out at regular intervals.
