Primary-Secondary Integrated Distribution Network Module

To ensure the universal interchangeability of equipment from different manufacturers within a specified range and over a defined period, enhance the operational and maintenance convenience of ring main units (RMUs), and promote the high-quality development of integrated primary‑and‑secondary RMUs, the company has coordinated China Electric Power Research Institute Co., Ltd., design institutes, operating entities, manufacturing enterprises, and testing organizations to undertake standardized design work on typical structural configurations, primary interfaces, distribution automation terminals, and other components. This approach facilitates the seamless replacement of entire units with equipment from other manufacturers when failures occur during operation or when quality issues are identified through random inspections, while also ensuring that the internal structures of products from various manufacturers remain consistent.
