The high-voltage cable assembly is a high-voltage electrical product used to realize the electrical connection of roof high voltage circuit. It mainly consists of high-voltage cables and their supporting cable accessories. Common cable accessories for locomotives include T-shaped connector, outdoor terminal and indoor terminal. In addition to the above cable accessories, EMU also includes the L-shaped connector.
Nearly 8000 high-voltage cable assemblies produced by CED have been installed on power centralized EMUs, HXD2 and HXD3 series electric locomotives. The products are mature and reliable with strong technical strength and rich operation and maintenance experience.
