This paper describes a thermal model of electric contacts suitable for power circuits, especially for pantograph–catenary system used to supply the electric vehicles as tramways and trains. Because the contact pieces are made of different materials, the thermal model deals with two different thermal power loss using fractions of the total thermal power. The maximum contact heating and the heating distribution expressions have been established for both contact pieces. This model has been validated for an electric contact between a small pantograph and a copper disc with the aim to simulate the contact between the pantograph and the catenary. The model can be used to analyse the thermal behaviour of electric contacts made of different materials at different values of the electric current, contact force or ambient temperature, in steady-state conditions.
