In 2023, Global Brothers International—a certified partner of China’s nuclear power industry—was selected to supply the 110kV high-voltage switchgear and auxiliary power distribution system for Phase II of a coastal nuclear power plant in Eastern China. The facility is part of China’s national strategy to expand clean, baseload energy capacity.
Challenges
- Zero-failure requirement: Nuclear facilities demand absolute reliability—any electrical fault could trigger safety protocols or shutdowns
- Stringent compliance: Equipment must meet GB/T, IEC 60880, and nuclear-grade seismic resistance standards
- Tight integration: Systems needed seamless compatibility with existing plant control architecture
- Long-term support: Client required 15+ years of maintenance and spare parts availability
Our Solution
Leveraging our deep experience in nuclear-grade electrical engineering, we delivered a fully customized, factory-tested solution that met all technical, safety, and lifecycle requirements.
✅ 110kV High-Voltage Switchgear
- SF6-insulated metal-enclosed switchgear, rated for 110kV / 31.5kA
- Integrated protection relays with redundant communication to DCS
- Seismic qualification: Designed to withstand 0.3g horizontal acceleration (exceeding GB requirements)
- Factory acceptance test (FAT) conducted under client supervision
✅ Auxiliary LV Distribution System
- 400V switchboards with intelligent metering and load management
- Dual-power automatic transfer system (ATS) for critical loads
- All components traceable with nuclear-grade material certification
Results
- ⚛️ Successfully commissioned in Q4 2023 with zero defects
- 📊 System uptime: 99.98% during first year of operation
- 🔍 Passed rigorous on-site inspection by China National Nuclear Safety Administration (NNSA)
- 🤝 Extended partnership: Awarded follow-on contract for Phase III in 2025
Why It Matters
This project underscores Global Brothers’ role not just as a supplier—but as a trusted enabler of national energy security. In high-stakes environments like nuclear power, trust is earned through precision, compliance, and unwavering commitment to safety.
When failure is not an option, excellence is the only standard.
