The integrated primary and secondary distribution RMU is designed to meet the specific requirements of the State Grid Corporation of China, offering seamless interchangeability of equipment from different manufacturers within specified parameters. This enhances the convenience of operation and maintenance, allowing for direct replacement of faulty or substandard equipment without the need for complex system redesigns.

This innovative solution integrates both primary equipment (RMU), sensors, and secondary components (control systems, distribution terminals) into a complete ring main unit. It effectively manages both high-voltage and low-voltage distribution, protection, and control, making it ideal for urban power grids, industrial power systems, and large buildings.
