It is an imperative prerequisitefor the safe and economic opera-tion of both – Light and HeavyRail transit vehicles – to assureuninterrupted and complete cur-rent collection from the catenary– or the power rail.
It is Schunk’s worldwide objectiveto design, manufacture, and pro-vide a variety of individual com-ponents to support efficient railand road operations.
We Supply
complete pantographs carbon current collector strips
for roof pantographs carbon current collector strips
for 3rd & 4th rail applications carbon current collector inserts
for trolley pole systems
Why Carbon?
The excellent physical propertiesof carbon have been exploited formany decades to transmit powerfrom overhead contact wiresand/or power rails to electricallyoperated vehicles. Some of thoseproperties are:
an excellent sliding capability great electric and heat conduc-
tability high mechanical strength good damping properties no tendency to weld formation of protective coating
(patina) largely corrosion proof stable contact conditions prevention of radio interference
As the result of the advancesmade in the design of electricallyoperated traction units, greaterdemands have been placed on thecontact material, which conse-quently facilitated the worldwideintroduction of carbon compo-nents for current transfer. Themost important demands are:
increased vehicle performanceexpectancy
superior comfort higher speeds reduced operating costs
Schunk supplies appropriate car-bon grades, and suitable carriermaterials, for almost all require-ments.

Grades – Current Load
Guide-Line for Current Load – Pantograph Sliding Strips
All values mentioned are calculat-ed per mm sliding strip width.
Operating Currents above thegiven range will result in shorterlifetime.
Standstill currents are subject ofvarious factors i.e.: material,cross sectional area, type andstate of the catenary, permissiblecatenary temperature, mean con-tact force per strip and last but
not least the carbon grade in use.Further details will be given byour engineering department orany subsidiary listed on page 14in this brochure.

Permissible Peak Current Load
Among specific conditions dur-ing operation peak currents 50 %higher than the mentioned guide-line values are possible. Furtherdetails will be given by our engi-neering department or any sub-sidiary listed on page 14 in thisbrochure.

Note: Alternate suggestions toallow greater load than the abovemaximum ratings:
usage of higher load capacitygrades and designs
wider contact surface by em-ploying wider carbon profiles
more current collector strips(e.g. 4 strips instead of 2 strips,or 2 strips and one center, etc.)
more catenary wires acceptance of a higher wear
factor
The wear of the carbon currentcollector strips is influenced bytwo factors, the electrical and themechanical wear.

Guide-Line Values for Current Load – 3rd & 4th Rail
The 3rd Rail contact is a planecontact. Therefore the standardvalues are given as an area unit.The maximum permanent current-carrying capacity during opera-tion is 10 A/cm2 for plain carbongrades, for metal-impregnated ver-sions 12 A/cm2 and 15 A/cm2 forthe casted design.
Modern METRO- and SUBWAY-Systems utilize 3rd Rail systemsto satisfy the current supply. Thepower rails consist mostly ofsteel, bronze, or aluminum alloymaterials. Typically the contactsare exposed to the followingloads:
Requirement Profile
mechanical impacts high starting and stopping cur-
rents high dust exposure
Compared to conventional cur-rent collection systems withmetal contacts, carbon gradeshave the following advantages forthose applications:
careful treatment of power rail excellent sliding property minimal arcing low noise level reduced weight
Due to the high mechanical wearand tear, grades with a high den-sity are preferably used. De-pendent on the electrical loads,carbon, or metal-impregnated car-bon, is utilized.

Carbon Inserts – Trolley Pole Systems
With electrically operated bussesthe current transfer from thecatenary to the vehicle is con-ducted by means of a current col-lector head, which is mounted tothe end of a trolley pole. Contactwith the catenary is achievedthrough a carbon insert, which isclamped exchangeable into ametalshoe.

Design Variations
Schunk supplies carbon inserts inall of the above mentioned gradesfor all customary collector shoedesigns.
The double-wedge-shaped insertproved itself again and again, dueto its easy and safe installationand the great fit into the collectorshoe.By tailoring the insert to thecross sectional area of the cate-nary, an optimization of contactcondition can be achieved.
