Carbon slides, current collectors

1. Application:

Carbograf Sp. z o.o. company continues the production of carbon slides for tram, trolley, railway, and industrial traction, started by Zakłady Elektrod Węglowych (Factory of Carbon Electrodes) in Racibórz decades ago. Years of experience and constant improvement of production technology results in a product successfully competing with other producers of materials made of carbon and graphite.

Zakłady Elektrod Węglowych (Factory of Carbon Electrodes) in Racibórz was a producer supplying all the national rolling stock (except for railway traction) in carbon contact strips for electricity receivers. It allows to constantly implement our client's remarks in order to improve quality and lower production costs.

Currently these experiences allow CARBO-GRAF company produce carbon strips with a high rate of quality to the price, what is very convenient for our clients.

Advantages of using properly chosen carbon shoes are indisputable, especially when it comes to:

  1. durability of traction wires

  2. elimination of breakdowns caused by welding of the receiver with a traction wire

  3. elimination of radio interference

  4. lowering of the noise

  5. lowering of exploitation costs

2. Assortment of offered slides and current collectors:
3. Dimensions of the offered slides and current collectors:
4. Composite material parameters:
5. Research and development.

As of late, CARBO-GRAF Sp. z o.o.  is developing a technology of manufacturing glued carbon slides for aluminum tram and railway pantograph frames, based on its own technology of gluing and construction of frames. Our slides are characterized by product innovation consisting in the fact that in one product there is a set of many functional and utility features, such as:

  • ability of the sliding contact strips to transfer high electric charges

  • high durability and resistance to systematically occurring service loads

  • high abrasion resistance by optimizing the hardness of the composite

  • increasing the operating comfort for the user

 

In this regard, we cooperate with national research and development centers, including AGH Kraków, the Institute of Non-Ferrous Materials in Gliwice, and the Silesian University of Technology. We are currently working on a technology for manufacturing a new generation of carbon material that allows for a significant reduction in the mass of the slide, reducing the resistance between the slide plate and the self-supporting housing, and improving the dynamics of its work.
