                        Perii electrografit            

               Periile electrografitice sunt utilizate in general pentru motoare si generatoare de curent continuu, masini stationare pentru echipamente industriale, masini tehnologice utilizate in siderurgie, textile, industria celulozei si hartiei, prelucrarea cauciucului, servomotoare cu intrefier axial, motoare electrice universale. In tractiunea electrica, varietatile periilor electrice sunt folosite pentru echiparea masinilor electrice auxiliare pentru locomotive si pentru metrou, si pentru echiparea motoarelor de tractiune urbana (tranvaie si troleibuze).
