The slip ring system is the core component of the main and auxiliary generators of the railway diesel locomotive. It is located between the generator and the locomotive converter to provide the rotor with a stable excitation current. The slip ring system needs to endure harsh operating conditions such as high temperature, high current, and vibration. Through design simulation, Morteng selects high-strength and good electrical conductivity materials, uses special technology to make locomotive slip ring system, and verifies the performance and durability of the product through simulation tests. The effect is excellent in customer application sites and successfully replaced imported products. .
