This pantograph model is a high-speed current collector independently developed by HengtaiRail based on the absorption and integration of DSA series pantograph technologies.
Its structural strength has been optimized through finite element analysis and 3D design platforms such as I-DEAS, achieving enhanced aerodynamic performance.
Additionally, pantograph-catenary coupling performance has been refined using dynamic simulation software. The pantograph fully meets the operational requirements of passenger EMUs running at speeds up to 300 km/h.
