CARBON CURRENT COLLECTORS AND CARBON SHOES
 
   Electrical Contacts – Our Competence
 


PanTrac – emerged from the consolidation of the electrical contact businesses of SGL Carbon GmbH, Werk Ringsdorff and Elektrokohle Lichtenberg AG, Berlin - is a center of competence for electrical contacts within the E-Carbon Group.

Electrical Contacts for railway applications are one main facet of our business. Carbon Current Collectors – made by PanTrac – distinguish themselves by excellent application performance.

The carbon profiles are produced by SGL CARBON GmbH Werk Ringsdorff one of the largest manufacturer of carbon and graphite products worldwide.



 



  Advantages of PanTrac Carbon Current Collectors
   
Your benefit: Reliability and low Life-Cycle-Cost

 

Low wear rate of our carbon grades RH 84, RH 83 M6

 

 Lead free metallized carbon grades for high and very high current load (RH 84 M6, RH 83 M6, RH 85 M6)

 

 Bond between Al-carrier and carbon profile is by an electrically conductive glue

 

 Bond is heat-resisting up to 300°C

 

 Tested with short circuit current of 30 kA (half-wave 16 2/3 Hz)

 

 Reliable Automatic-Dropping-Device system

 

 Reliable – Quality Control System – (acc. to pr EN 50405)
