Spl. Pressure Blasting Mc for of Electric Rails & Tramways Roof-mounted Pantographs Contact Strip Machine

A Pantograph Contact Strip is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. The carbon strip’s friction and wear properties are affected by the electric current, and the wear rate increases with higher electric intensity.

Surface roughness plays a crucial role in the pantograph-catenary system used in electric trains. Higher roughness can lead to higher friction, which might increase wear on the pantograph strips, but also provides better grip, improving current collection stability.
