Nuclear low voltage switchgear plays a critical role in nuclear power plants by ensuring safe and reliable power distribution.
Our nuclear low voltage switchgear is designed to meet strict safety, seismic, and quality standards for critical applications.
The Role of Nuclear Low Voltage Switchgear in Power Plants
Nuclear low voltage switchgear plays a critical role in controlling and protecting motors, pumps, ventilation systems, lighting, and heating loads. It serves as the backbone of auxiliary power systems in nuclear facilities.
Due to the high-risk operating environment, safety and reliability standards for nuclear switchgear are significantly stricter than conventional industrial applications.
Compliance with Strict Nuclear Quality and Safety Standards
All nuclear low voltage switchgear must comply with national and international nuclear regulations and complete comprehensive qualification procedures.
Key requirements include:
Dedicated technical specifications for Q2 and Q3 equipment
Seismic, aging, and failure testing for nuclear island equipment
Safety interlocking, anti-misoperation, and redundancy design
These measures ensure long-term stable operation under extreme conditions.
High-Reliability Components and Lifecycle Monitoring
Core components must meet strict mechanical and electrical endurance standards.
Intelligent Monitoring Functions
Important circuits are equipped with:
Operating time counters
Breaker opening and closing counters
Real-time status monitoring
This enables full lifecycle traceability and predictive maintenance.
Emergency and Normal Power Distribution Systems
Nuclear low voltage switchgear is mainly divided into two categories:
EE Emergency Switchboards
1E K3 safety classification
Q1 quality level
Class 1 seismic resistance
Designed for emergency power supply systems.
ER Normal Power Switchboards
Q3 quality level
NO seismic class
Suitable for normal operation systems
Both systems form a complete nuclear power distribution network.
Structural Design for Harsh Nuclear Environments
Nuclear operating environments require advanced structural and manufacturing solutions.
Key design features include:
Standardized installation methods
Reinforced cable entry systems
High insulation and heat resistance
Anti-corrosion surface treatment
Clear and durable product identification
These designs ensure long-term stability in high-temperature, high-humidity, and radiation environments.
