The mobile ring main unit (RMU) truck mainly consists of a chassis vehicle, a high‑voltage cabinet, a control system, bypass high‑voltage cables, quick‑plug separable connectors, an enclosed compartment, a grounding grid, a support system, an electrical system, and on‑board tools and accessories.
An open, modular frame‑type compartment structure is adopted to make full use of all available space.
The RMU and cable termination device can be removed as a whole, enabling multi‑purpose use of the vehicle and improving equipment utilization.
An internationally renowned brand such as ABB is selected for the high‑voltage compact RMU, featuring two inputs and four outputs, electric/manual operation, and high‑voltage quick‑plug interfaces.
