Electro-graphite brushes for alternating current motor

Lampar, specializing in the production of carbon brushes of any type and dimension for electrical machines, manufactures and sells electro-graphite brushes for alternating current motors (AC motors).

Electro-graphite can be obtained from carbon material, precooked and hardened at a temperature higher than 2500ºC in a graphite furnace, where the conversion of carbon in to electro-graphite happens; the most part of impurities are removed and its physical characteristics are considerably better then the hard coal's ones.

Electro-graphite has excellent properties of switching and a high level of safety against short circuits and burning.
