Copper graphite carbon brush is one of the important types of carbon brushes. Since its main components are copper powder and carbon powder, it is also called copper-carbon alloy carbon brush. Copper graphite carbon brush has the advantages of small resistance coefficient, strong conductivity, fast heat conduction, resistance to arc erosion, high temperature resistance, good lubrication performance, and corrosion resistance. It is mainly suitable for various large DC motors, generators, collector ring motors, and other motors that require high current density. It is an ideal material for preparing modern self-lubricating friction parts and electrical contact conductive parts. Its demand fields are very wide, covering mechanical transmission, transportation, military, aerospace, and other fields that require friction reduction and conductivity. Copper graphite carbon brushes can be divided into low copper, medium copper, and high copper carbon brushes according to the copper content. The pantograph slide is an important current collection element on electric locomotives. It is installed at the top of the pantograph and directly contacts the overhead contact wire. During train operation, it obtains current from the contact wire to supply power to the locomotive. The pantograph slide must have good friction reduction and self-lubrication properties, certain wear resistance, sufficient impact strength, very low resistivity and contact resistance, and good heat resistance and arc resistance.

Busbar current collector is one of the most important components in the busbar system. The busbar current collector is the main device for picking up electrical energy on the current collection side in the busbar system. It directly conducts electrical energy to the electrical equipment through the sliding contact between the current collection brush and the guide rail, thereby achieving mobile power supply for the system. The current collector consists of two parts: a mechanical tension device and a current collection brush that directly slides in contact with the guide rail.
The mechanical tension device determines the sliding contact pressure between the current collection brush and the guide rail and the stability of the mechanism. The current collection brush is the conductor that slides in contact with the guide rail to pick up electrical energy. Its performance, conductive quality, and the quality of material structure and composition will directly affect the safe operation quality of the entire system equipment. (Industry: busbar, sliding wire, sliding conductor, sliding contact mobile power transmission and supply)

Note: When selecting a current collector, the capacity of the current collector should match the electrical equipment. When the single-pole capacity is insufficient, a double-pole current collector can be used. The lateral movement distance and contact direction movement distance can be enlarged according to user needs.
