Explore our premium range of smart distribution equipment and integrated power networks engineered for utilities and industrial systems.
The global power sector is experiencing a paradigm shift towards decarbonization, decentralization, and digitalization. Modern power systems face significant challenges with the integration of intermittent renewable energy sources, the electrification of transport, and the increasing frequency of extreme weather events. Smart grid distribution automation equipment acts as the central nervous system of modern power networks, ensuring continuous power flow, rapid fault isolation, and optimized load management.
Distribution Automation (DA) technologies encompass automatic monitoring, protection, and control systems implemented at the medium and low-voltage distribution levels. These systems, utilizing intelligent Ring Main Units (RMUs), metal-clad switchgears, and digital microgrid components, enable real-time grid observability. By deploying advanced sensors and communication units (such as DTUs/FTUs), power distribution systems can automatically identify faults, isolate the affected sections, and restore power through alternative paths (FLISR: Fault Location, Isolation, and Service Restoration), dramatically reducing average outage durations (SAIDI) and frequencies (SAIFI).
"By integrating real-time telemetry, solid insulated green switchgears, and edge computing automation controllers, modern distribution networks can adapt dynamically to complex bidirectional energy flows."
Edge sensing and intelligent remote control units (DTU/FTU) bridging the physical MV/LV infrastructure to Cloud Energy Management Systems.

1. Vertically Integrated Production Ecosystem: From raw copper/silicon steel preparation, CNC shearing, and precision bending to specialized processing such as epoxy resin casting and oil-immersed vacuum treatment, all key phases are executed in-house. This minimizes reliance on third-party suppliers and accelerates production speeds.
2. Advanced Testing Facilities: Every switchgear unit and transformer undergoes rigorous routine tests—including power frequency voltage withstand tests, partial discharge tests, and primary current injection checks—before shipping. This ensures international compliance with VDE, CCC, and ISO9001 guidelines.
3. Logistics and Delivery: Situated in Ningbo, our facility is positioned near major deepwater ports. This geographical proximity reduces transit times and transport costs, enabling streamlined shipping logistics for large-scale utility and industrial deployments.
