This part is suitable for the transmission of electric energy for electric traction vehicles in the third rail power supply system of the railway. The current carrying capacity is 3000-4500A. The standard manufacturing length of a single steel-aluminum contact rail is 15m, and contact rails with non-standard lengths can also be produced according to site construction and design requirements. If the passing frequency of the power receiving shoe reaches more than 1 million times per year, the test shows that the wear of the contact rail steel belt is only 0.03mm. In the course of use, when the thickness of the stainless steel surface wears to 2mm. the contact rail should be replaced. Based on this calculation, the service life of the contact rail can reach about 60-80 years.
